XXXIII. APRIL. 1919. No. 1. INTRODUCTORY. With the March, 1919, issue. The OTTAWA Naturalist, the official organ of the Ottawa Field- Naturalists' Club, ceased to exist under that name. The Ottawa Naturaust had a long and honour- able career. Like all similar publications it had its trials, its ups and downs, financial troubles, etc., but it weathered all storms and appeared fairly regularly during its thirty-two years of existence. In its pages are to be found many articles of great scientific value and we would like to have space to remind our readers of at least some of the more important of the contributions which it presented. With the increase in its size, improvement of paper, specially prepared articles, etc.. Vol. XXXII, certainly may be regarded as an excellent production and one which has brought forth many words of encourage- ment from its readers. This, the April issue of the organ of the club appears under a new name The CANADIAN FlELD- Naturalist. Such a change was intimated in the April, 1918, issue of The Ottawa Naturalist, and at the recent annual meeting of the Club, held on March 18, 1919, the same was duly approved. This change in name will not, of course, affect in any way the spirit of the publication. Such change only reflects its widened sphere of influence. We hope it will develop along improved lines and ultimately be accepted as the organ not only of The Ottawa Field-Naturalists' Club, but of similar organizations throughout Canada. There is an ex- cellent opportunity for the naturalists of Canada to assist in building up this publication and making it truly representative of Canadian scientific research. The popular side will, of course, not be overlooked. Special efforts will be made to make it useful to amateur naturalists, teachers and the public gen- erally. The subscription price for the present volume which will contain six issues, namely for the months of April, May, September, October, November and December will be $1.00. Thereafter the volumes will consist of nine issues each volume beginning with the January number; the subscription price of each volume will be increased proportionately. NOTES ON THE CASPIAN TERN (STERNA CASPIA) AND THE PARASITIC JAEGER (STERCORARIUS PARASITICUS) IN MANITOBA. By Professor Chas. H. O'Dongghue, D.Sc, and J. Nelson Gowanlock, B.A., Fellow in Zoology, Zoological Department, University of Manitoba. Island faunae, ever an interesting field in orni- thology, become particularly attractive in contin- ental areas where lake islands afford the only suit- able breeding grounds for certain water birds. The following observations refer to a small but interesting island in the northern part of Lake Winnipeg visited on July the 9th and 1 3th, 1918, whereon a colony of Caspian Terns (Sterna caspia) was found. No record of this species breeding in Manitoba has hitherto been published. A specimen of Parasitic Jaeger (Stercorarius parasiticus) was also secured and constitutes the first inland record for this province. Through the courtesy of the Riverton Fish Company, of Riverton, Man., the authors were enabled to make the journey a round trip of some 500 miles from Hnausa to Berens Island. The objects of the trip were first to study if possible, breeding colonies of White Pelicans (Pelecanus erythrorhynchos) and second, to gather some idea of the biological conditions on the northern portion of the lake. The original intention to make Rein- deer Island the base proved impracticable and a camp was established at Swampy Bay, Berens Island, where the Riverton Fish Company main- tained a large fishing station. We desire to express The Canadian Field-Naturalist [Vol. XXXIII. our warm appreciation of the sympathetic assistance afforded by the men at the stations, particularly by Mr. Johnny Jonasson. Berens Island was chosen mainly because of the possibility that White Pelicans would be found breeding on Pelican Island which lies some four or five miles west of Berens Island. Pelican Island lies approximately in longitude 951/2 and latitude 52!/2 and is a typical, rocky lake island, some ten to fifteen acres in extent. Between Pelican Island and the northern shore of the lake, there are no islands and so its north coast meets the full force of the waves raised by the winds sweeping across this 100 miles of open water. Lake Win- nipeg with its area of over 8,000 square miles, is very dangerous owing to its quick changes from calm to storm and fishermen familiar with the whole lake, declare this region between Pelican and Berens Islands to be the worst. The shores of Pelican Island are extremely rocky ^there are no sand beaches and a landing from a rowboat requires cautious management even in calm weather. The island is partly wooded with birch, ash, etc., but inland the ground is depressed in a basin-like central hollow, overgrown with marsh vegetation. A barren tongue of land juts out from the east side of the island forming a shingle spit. THE TERNERY. The first time the authors approached the island in a skiff, flocks of birds were observed resting on the eastern point, while with prism binoculars. Herring Gulls and Terns could be distinguished everywhere along the shingle spit and adjacent shore. Two young Herring Gulls, still in natal down, ran down the beach to the water as the boat reached land. One of these was captured. The uproar among the birds caused by the landing increased when the shingle spit was reached. Numerous de- serted Herring Gulls' nests, substantially built of vegetable debris, lined the edge of the grass zone or were scattered over the bare pebbles and every- where were the remains of pellets disgorged by the gulls. No eggs were found until the zone of vegetation had ended, when, passing out onto the bare eastern spit, a densely populated ternery was discovered. Over this space were between 200 and 300 occupied nests, frequently almost touching, each containing one or two eggs. After a brief survey of the ternery, a low hiding blind was erected and left for the birds to return to the colony. On returning later, the whole colony was seen to be still on the wing, shrieking and screaming above the breeding ground. The cause was soon revealed. In the midst of the colony was a fisherman method- ically gathering the eggs from the nests. The old fellow could scarcely understand English and after much difficulty, it was explained that some of the nests were to remain undisturbed. The birds were now so thoroughly alarmed that an hour spent in the hiding-tent in the hope of photographing them proved vain and the remaining hour or so of light was expended in examining and photographing the nests and eggs. An adult Caspian Tern was col- lected together with some clutches of eggs. A fair portion of the colony had not been disturbed. It was hoped that the next visit would find the owners of these nests back at the task of incubation and so the hiding-tent was left in position, as carefully concealed as possible. On July 13, Pelican Island was re-visited. The birds were observed as before, resting on the rocks and along the shore. On approaching the breeding ground, the usual alarm of the parent birds was not in evidence and closer examination showed that every remaining egg had been destroyed evidently by crows (vide infra) and on the whole spot not a single occupied nest remained. A specimen of Parasitic Jaeger and two still occupied Herring Gull nests were also discovered during this visit. Reference to the published records of Manitoban birds yielded only an isolated record of the Caspian Tern. It is not mentioned by Bell (3) nor by E. Thompson Seton (II and 12) and is recorded only by Nutting (6) whose record is cited by Preble (7). Nutting collected a single Caspian Tern on Lake Winnipeg at the mouth of the Saskatchewan river in 1892. The A.O.U. Check List (I) says of the Caspian Tern: "Range nearly cosmopolitan" but gives few North American breeding records, viz: "Great Slave Lake, Klamath Lake, Oregon, on islands of northern Lake Michigan, on coast of Southern Labrador, and also on coasts of Texas, Louisiana, Mississippi and (formerly) Virginia". The discovery of such a colony in Lake Winnipeg is, therefore, of unusual interest. Although there are no published records of the species breeding in Manitoba, we have reason to believe that it was previously recognized by Mr. Eric Dunlop, since killed in action in France, a naturalist who in 1914 and 1915 collected in northern Lake Winnipeg for the Carlisle Museum, Carlisle, England. Dunlop is said to have found the Caspian Tern breeding on the west coast of Reindeer Island, but, unfortunately, his records are not available. While in the north, the authors met with Dunlop's chief guide, Capt. Goodman, who through his work with Dunlop had become acquainted with many of the birds. Capt. Good- man stated that in 1914 the Caspian Terns were found breeding only on the west shore of Reindeer Island and had not been noted anywhere else although numerous islands, including Pelican Island, were then visited.

The Caspian Terns' nesting ground was a com- pact area situated on a slope of the shingle spit and measured only some 20 yards by 30 yards. The ternery sloped from some 10 to 12 feet above lake level at the highest point down to some four feet above lake level at the lowest point. In this space were well over 200 nests. Somewhat over 400 eggs were noted and exact measurements taken of 46 of them. A small, peculiar pond to the west of, and some 10 yards from the boundary of the ternery, contained a few water plants and algae and was well populated with large frogs (Rana pipiens). This pond showed every evidence of being much visited by the birds. Between 600 and 800 adult Caspian Terns must have been observed on the first visit, the birds resting on the stones along the shore, fishing cff-shore or flying together with Herring Gulls and Common and Forster Terns above the island. The stomach of the individual shot con- tained remains of small fish. The identity of the species was first suspected from the size and shape of the eggs, later determined by close range observa- tion from '.he hiding-tent and finally confirmed by the finding of dead specimens and the shooting of an adult female. The nest frequently consisted of mere depressions in the shingle, absolutely no vegetable or other materials being utilized. In some other instances, grass bents, dead rushes, bits of drift, etc., were gathered together forming a rude, basin-shaped structure. Thus the type of nest appears to re- semble most closely that of Lesser Tern (Sterna m'lnuta) (9) and not that of the Common Tern (Sterna hirundo) (10) which most frequently builds quite a noticeable nest of gathered materials. The deserted and much better constructed nests of Herring Gulls were occasionally used by the Cas- pian Terns, apparently no additions or alteration being made by the new tenants. In no case did the number of eggs in a nest exceed two. Frequently, there was only one egg, usually fresh, in a nest. It is of interest that Van Winkle (5) records three as the usual number of eggs per nest on the Gravel Gull Islands, Lake Michigan, whereas we found that in some cases where there were two eggs m the nest, they were both in such an advanced stage that there would have been ample time for the third egg to have been laid had three been the normal number of the clutch. The eggs exhibited a considerable range of varia- tion in color, size and type of marking, but destruc- tion by the fishermen and the crows prevented the taking of a series of measurements similar to those made by Rowan, Parker and Bell (10) as was originally intended. The measurement of a char- acteristic series of 46 eggs was fortunately secured, from which the following data were obtained: Average length, 63.59 m.m. ; average breadth, 43.84 m.m.; greatest length, 72.00 m.m.; shortest length, 56.00 m.m. ; greatest breadth, 46 m.m. ; least breadth, 41.00 m.m. The two eggs of a clutch sometimes differed con- siderably, though a sufficient number were not ex- amined to allow of satisfactory statistical treatment. Thus: in clutch No. 33 the two eggs were 70 x 46 and 67 X 45 m.m.; in clutch No. 23 the two eggs Avere 66 X 45 and 63 x 43 m.m. Like differences were found also in color, for in one nest one egg was of a pale blue background with a few very faint spots, while the second was he-^vily spotted and blotched wi;h black upon a brown background. The eggs that were opened and examined exhibited every stage of development from practically no incubation, the primitive streak stage, through to large embryos. The majority, how- ever, were fresh. None seemed less than a week from hatching. THE PARASITIC JAEGER. The Parasitic Jaeger (Stercorarius parasiticus) of which a specimen was found on July 23 on the north end of Pelican Island, is also a bird of some interest as it is the first record for this area. The Canadian Catalogue of Birds (Macoun, 5) gives the following record for Hudson Bay: "a specimen of the melanistic form (of Stercorarius parasiticus) taken at Fort Churchill, Hudson Bay, 1845 (Dr. Gillespie, Jr.)" Preble (7), however, records the species as occurring on the coast of Hudson Bay, below Cape Eskimo in 1900. Both of these, how- ever, are on the sea-coast and at least 500 miles north of Pelican Island. The two other members of this strange genus, the Pomarine Jaeger (Stercor- arius pomarinus) and the Long-tailed Jaeger ^5. longicaudus) have been recorded for Manitoba, the former on Hudson Bay (Preble, 7) and the latter once from Aweme, Man., May, 1903, by Mr. Norman Criddle (Macoun, 1909) and also once from Clandeboye, Man., October, 1902, by Atkin- son (2). The specimen of Parasitic Jaeger which the authors discovered was lying dead on the rocky ground above the drift line in the midst of a de- serted Herring Gull colony. The individual was an example of the white phase. From the situation and appearance of the bird it is possible that it had been killed by Herring Gulls while poaching on the colony, a fate several times recorded for this species. OTHER BIRDS. The following observations were made concern- ing other species of birds noted on Pelican Island: HERRING GULL (Larus argentatus). This species April, 1919] The Canadian Field-Naturalist had practically completed breeding. Over 300 de- serted nests and but four occupied nests were dis- covered three with well-grown young and one with eggs. RING-BILLED GULLS ( LaTus delaTvarensis) were noted in company with the last species. forester's terns (Sterna forsteri) and COMMON TERNS (Sterna hirundo) were numerous, almost equalling the Caspian Terns in numbers. The gulls and terns all consorted together freely. BLACK TERNS ( Hydrochelidon nigra surinamensis) were entirely absent although they are quite numer- ous in the south end of Lake Winnipeg. WHITE PELICAN (Pelecanus erythrorhynchos) were not noted, although excreta and two humeri were found. However, the species was regularly observed fishing in Swampy Bay, five miles from Pelican Island, so it probably is a frequent visitor here also. SCAUP DUCKS (Marila mar'da or M. affinis) were observed, five or si.x individuals together, resting on the water not far offshore from the ternery. MALLARD (Anas boschas) were observed and one adult female collected. WHITE-WINGED SCOTERS (Oidemia deglandi) are frequently caught and drowned in the fishermen's nets. They probably visit Pelican Island frequently. Two or three LEAST SANDPIPERS (P'uob'.a minu- tilla) were observed on the beach. LESSER YELLOW-LEGS (Totanus flavipes) were seen feeding along the water-edge. A PECTORAL SANDPIPER (Phobia maculaia) was shot out of a flock of five feeding near the ternery. Several SPOTTED SANDPIPERS (Aciitis maculaia) were found feeding along the shore. Night hawks (Cbordedes virginianus) were noted at Swampy Bay and very probably inhabit Pelican Island. None was observed probab'.y because both visits were made during daylight hours. CROWS (Corvus brachyrhynchos) were common on the island. When the ternery was first visited, the crows gathered near at hand to watch the pro- ceedings. When the second visit was paid, the crows were disturbed from the area of the ternery itself, where they were engaged in eating the Caspian Terns' eggs. The crows appear to feed largely upon the dead fish cast up by the water and they were constantly observed patrolling the shores in search of such food. Nests were found in considerable numbers. SAVANAH SPARROWS (Passerculus sandivichcnsis savanna) were in song and apparently breeding near the ternery. CEDAR WAXWINGS (Bombyc'dla cedrorum) wers common in the trees on Pelican Island. They were still in flocks and had not yet, apparently, begun nesting. RED-EYED N'IREOS (Vireosylva olivacea) were noted here as they were on every island and bit of the wooded shore the authors visited during the whole trip. YELLOW WARBLERS (Dendroiza aestiva aesliva) were common and breeding. BLACKBURNIAN WARBLERS (D^ndroica blacff- burniae) were noted and were in full song. The discovery of the Caspian Tern Colony on Pelican Island is especially interesting in the light of our knowledge of the distribution of this bird. The A. O. U. Check list (1) gives the winter range of this species as "South Atlantic and Gulf Coasts". To and from this region, logically, the Pelican Island terns must each year journey; yet there is not a single record of a Caspian Tern being collected in Central or Southern Manitoba. The route of migra- tion that would seem most reasonable is that down the Red- River-Mississippi Valley chain, yet this ab- sence of records proves fairly conclusively that the Caspian Terns do not regularly or in numbers, tra- verse this path. The alternative suggestion is a migration route by way of Hudson Bay, thence to the Atlantic coast and thence southward. The Pelican Island and Reindeer Island colonies might thus possibly be explained as an invasion of this species from Hudson Bay, these islands the out- liers of the numerous islands including Berens Island being the' first of the group upon which the species has established itself. The birds in going to their winter range, still probably use the old route of invasion and travel circuitcusly out by way of Hudson's Bay and the Atlantic coast. Analagous to this might be cited the case of the Bobolink y'Dolichonyx oryzivorus) which, according to Ccoke (4) has invaded Utah by extending its range far westward, then southward yet in returning to its winter home in southern Brazil, the Utah bobolinks do not go directly, but move along their old invasion route. I.e., they first journey northward, then east- ward, then they turn south to their distant winter range. It is conceivable that in the case of the bobolink, a frequenter of damp meadows, its choice of route is partly, perhaps largely, determined by following such suitable localities and therefore it does not cross the arid regions to the south and southeast of the points reached in its new advance. Indeed it is only since the extension of irrigation in certain parts of Utah that it has made its appear- ance there. Whereas the Caspian Tern, having once got into the lake region has practically an unbroken inland water system over which it could return to the south. The Pelican Island colony is declared by the The Canadian Field-Naturalist [Vol. XXXIU fishermen, who recognize the Caspian Tern to be a new bird on the lake, to date within the last few years. Indeed the earliest definite information re- garding it was their report that three years previous to our visit, a wolf crossed to Pelican Island from Swampy Bay and destroyed all eggs and young birds in the colony. The species was not found by Dunlop when he visited the island in 1914 and it is hardly possible that he could have missed it had it been there. Capt. Goodman stated that, on Rein- deer Island, Dunlop found the Caspian Terns breed- ing as late as mid-August. REFERENCES. 1.

Much interest has recently been aroused over what appears to be phenomenal deposits of sugar on the leaves of Douglas fir (Pseudotsuga laxifolia) in cer- tain areas of British Columbia. Although Douglas fir sugar has been known to the Indians of the dry- belt for many years, its occurrence seems to have been overlooked by the numerous surveyors and others who have travelled in the province; at least, in-so-far as the writer is aware, no record has been made of its occurrence previous to 1915, when an illustration appeared in the British Columbia Botan- ical Office Report for the year 1914, showing a branch of Douglas fir laden with white masses of sugar. This photograph was prepared from speci- mens received from Mr. Jas. Teit, of Spence's Bridge, B.C., who, in connection with his ethnol- ogical work on the plants used as food by the British Columbia Indians, wished to have an ex- planation of the deposits; Mr. Teit also forwarded samples of Douglas fir sugar to Dr. E. Sapir of the Geological Survey of Canada, who had the samples analyzed. During the summer of 1917, when the European conflict caused an increase in the cost of living and the introduction of measures to economize sugar, in- terest in this phenomenon was renewed and in- tensified by the appearance of a glowing account supplied to one of the Vancouver newspapers by some irresponsible contributor. As a result, a num- ber of people became quite enthusiastic regarding this "new" discovery and hastened to ascertain its commercial possibilities. In view of the fact that many people in Canada are interested in the phenomenon, and at the request of Mr. Teit, the writer consented to give a summary of what is known regarding Douglas fir sugar and the factors influencing its exudation as deposits on the leaves. All the information relating to the dis- tribution and habitats of sugar-bearing Douglas firs was supplied by Mr. Teit who, being resident in the heart of the dry-belt and having an intimate knowledge of the Indians of the interior, was best able to secure the necessary data. It appears that Douglas fir sugar cannot be relied on as an annual crop. Some years it is abundant, other years little or none is found. It is therefore regarded by Indians as an extra, rather than a necessary part of their food supplies, but when avail- able in quantity it is collected and may be kept for future use. NOT THE WORK OF INSECTS. Previous to having seen the specimens, the writer suspected that the sugar had been produced as an exudation on the leaves through punctures made by insects possibly aphides; such as is said to occur on Tamarix mannifera which, when attacked by a Coccus, yields a kind of mucilaginous sugar the manna of Mt. Sinai; but information to the effect that only healthy trees produced the sugar and that such trees were practically free from insec's. April, 1919] The Canadian Field-Naturalist with the exception of such as were feeding on the sugar, led one to suspect that the sugar might be related to the manna of commerce, obtained from several species of ash (Fraxinus) as an exudate wh]ch assumes the form of flakes or fragments. When specimens were received, however, in the summer of 1914, it was seen that none of the pre- viously recorded sugars corresponded with the pe- and pending the results of the analysis which was then being carried out by Dr. F. T. Shutt, Dominion Chemisi:, at Ottawa. APPEARANCE OF THE SUGAR. The sugar appears as white masses varying in size from '/4 of an inch to I J/2 or 2 inches in diam- eter. The smaller masses are formed like white drops at the tips of single leaves, occasionally two or three Brancli of Douglas fir laden with white masses of .sugar. (From B. C. Hot. Office Rep., 1914). culiar masses formed by Douglas fir. A careful search for information as to its chemical analysis revealed nothing to show that even its occurrence was known. On account of its interest and novelty at the time, the photograph in the Botanical Office Report was supplied to record its occurrence and illustrate the phenomenon, pending an investigation into the circumstances under which it was formed. leaf-tips are inbedded in larger drops, while the largest masses are usually scattered irregularly over the leaves and branchlets. The sugar tastes decidedly sweet, passing tempor- arily into a pasty consistency during dissolution in one's m.ou'h; it is completely soluble. When col- lected it IS quite hard and dry, with no tendency to be sticky. A slight rain is sufficient to dissolve the 8 The Canadian Fik'.d-Naturalist [Vol. XXXIII. sugar ofl the trees, and patches of recrystalized sugar may then be found at the base of trees or on the ground. Frequently, however, in this situation it daes not recrystalize but may be found in a fluid or semi-fluid condition which is attractive to flies and other insects. Sometimes, as above mentioned, insects feed on the sugar while still on the trees, and it is reported that bears go af^cr it, causing the breakage of many branches. EXUDATIONS BY OTHER PLANTS. A.s is well known, many plants have structures known as walerpores,, situated usually at the tip or apex of the leaves, and, in the case of lobed leaves, often at the tips of the lobes or teeth along the margin. Occasionally when the root-pressure is very active, so much water is forced up into the plant that the leaves become gorged witli water which escapes through these water-pores compar- able to a kind of safety valve. Most people are familiar with the drops of water at the tips of grass leaves in the morning after a hot dry summer day and a cool, clear night, giving origin to the Scotch saying, "Ilka blade o' grass keeps its ain drap o dew . In some localities, where the soil is calcareous, minute white incrustations of lime are found around the water-pores; ihese incrustations may be found on grasses, and are of common occurrence on certain species of Saxifrages which show them on every tooth along the margin of the leaves, such incrusta- tions are small, and are only formed under certain ecological cond tions, in which temperature of the soil and atmosphere, and water content of the soil are important factors. FACTORS INFLUENCING EXUDATION OF SUGAR. A review of the disfributicn, and various factors influencing the prcduction of sugar by Douglas fir, will prove of especial interest to physiological and ecological botanists, to whom the phenomenon will serve as a splendid illustration of the influence of environment en a plant which under ordinary con- ditions in Bntish Columbia does not exude sugar. DISTRIBUTION. The region in which sugar-bearing Douglas firs are most abundant, lies between the 50th and 51st parallels and between 12l-122 long. This in- cludes the driest and hottest part of the dry-belt of British Columbia. Within this area they are rather common in the Thompscn valley west of the mouth of the Nicola river, also near the junction of the Thompson and Fraser rivers at Lytton ; they have been found a little above Lilloet in the Fraser valley, but according to present information are not known to occur north of Clinton in this region. About 10 miles north of the apex of the angle formed by the junction of the Thompson and Fraser rivers, lies Betani valley, at an altitude of between 3,500 and 4,000 feet, some years sugar is comparatively abundant on trees in this region; the geology and flora is very different from that of the adjacent Thompson or Fraser valleys; here one may find sugar-bearing Douglas firs growing on the southern and south-western slopes having the great- est sun exposure. The soil produces a thick cover- ing of grass and other vegetation, indicating a plenti- ful supply of available soil moisture; differing in this respect from the dry gravelly southern and south-western slopes of the main valleys of the Fraser and Thompson. Suitable habitats are found at intervals over a considerable area of the dry-belt regions, in ad- dition to samples received from the north and south sides of the Thompson river near Spence's Bridge, Douglas fir sugar has been reported from around Kamloops and Savona, also from the Nicola and Similkameen valleys, and is said to be found in the southern part of Okanagan valley. In-so-far as the chief of the Kootenay Indians is aware, it is not known in the Kootenay country although it is re- ported by an Indian as being found in eastern part of Washington state. United States. HABITATS. The habitats in which sugar-bearing firs are found, are usually on gentle slopes facing east or north in that region of the dry-belt where the Doug- las fir is encroaching on the dry-belt flora. The trees are in comparatively open areas with abund- ant exposure to the sun. SOIL MOISTURE. As a rule, sugar is not found on trees situated on fully exposed southern or western slopes, nor on areas where Douglas fir forms a dense forest. Southern and western slopes, exposed to the full heat of the sun, dry cut much sooner than ground gently sloping to the east or north; the greater abundance of soil mcisture in the latter is a point to be kept in mind. ABUNDANT SUNSHINE. In the region above mentioned the descending zone of the Douglas fir and the ascending zone of yellow pine overlap, so that the trees are well exposed to the sun, not being so crowded as to limit the foliage to a narrow crown, as happens in dense forests. An abundance of leaves exposed to the sun will result in an abundant formation of carbohydrates during the day; under ordinary conditions these carbohy- drates would be removed from the leaves and trans- ported to growing tissues or storage tissues during the night. This normally takes place in most plants, including Douglas fir in its natural habitat in the coast area where it forms dense forests of gigantic trees. April. 1919] The Canadian Field-Naturalist TEMPERATURE OF SOIL AND AIR. In the dry-belt area it is evident that Douglas fir trees are exposed to the sun for a greater number of hours per day, the soil and atmosphere is warmer, the forests are more open, with freer circulation of air, than Douglas fir forests in the coast area. MAXIMUM ROOT-PRESSURE. It appears then that in years when Douglas firs are fully exposed to a long succession of hot, cloud- less days in midsummer, and provided with the re- quisite soil conditions (i.e., temperature and available water) the trees gradually accumulate an excess of carbohydrates during the many hours daily ex- posure to sun, the increasing temperature of the soil enables the cells of the roots to maintain or increase their activity during the night, which in dry-belt regions in midsummer is very short, and during which root-pressure is at its maximum. DRY ATMOSPHERE. When night comes on, the chlorophyll-containing guard-cells have ceased photosynthesis, the guard- cells become isotonic (i.e., of equal concentration) with the surrounding cells, and the stomata close; so that even during warm nights little evaporation can take place from leaves so well protected with cutin. As a result of the increased root-pressure and ces- sation of transpiration the leaves become gorged with water in which the sugar formed by the re- conversion of starch into sugar is dissolved and exuded as drops at the tips of the leaves. The warm dry atmosphere at that time of the year causes the rapid evaporation of the water, leaving the sugar in the form of drops of various sizes as a deposit at the tip. Occasionally two or three such drops come in contact with each other and fuse to form one large drop, frequently they become so large that they fall from the leaf tips onto the leaves or branches below; a succession of these large drops cause the formation of the larger irregular deposits referred to above. There is no doubt about the exudation of the sugar from the leaf-tips; deposits may be found in all stages, from mere traces up to large drops, in some cases just dried as they were about to fall. With a knowledge of the ecological conditions under which Douglas fir exudes sugar, one can understand why it may be rare or absent in some years; one or two dull, cool, or wet days would suffice to alter one or more of the factors which play a necessary part in promoting its exudation. A dull day would enable the tree to utilize much of the excess sugar or store it as starch or other reserve food. A cool day would diminish the activ- ity of the sugar forming cells in the leaves, and by lowering the temperature of the soil would lessen the activity of the roots, thus diminishing the root- pressure and exudation of water, while a wet day and subsequent evaporation from the soil would more effectually lower both the soil and atmospheric temperatures. Other factors would be affected, bui the above summarizes the main points. ANALYSIS OF THE SUGAR. The results of Dr. Shutt's analysis of two sam- ples one supplied in 1914, the other in 1917 in- dicate a high degree of constancy of composition of Douglas fir sugar. The preliminary analysis made in 1914 gave the following results: Total sugars after hydrolysis 96.25% Reducing sugars 23.3 The analysis of the 1917 sample furnished the following data: Total sugars after hydrolysis 91.91 Reducing sugars 24.86 Foreign matter, etc., insoluble in water .64 Moisture 7.00 Subsequent to the analysis, a contribution* from the Carbohydrate Laboratory of the Bureau of Chemistry, U.S. Department of Agriculture, Wash- ington, D.C. a laboratory especially equipped for the examination of saccharine substances, reports a complete analysis of the same product. A summary of their findings is as follows: "The sample of Douglas Fir manna yielded abcul 50% of pure crystalline melezitose, and there IS evidence that the manna contains sucrose and some reducing sugar probably a mixture of glucose with a smaller quantity of fruc"^ose. The percentage composition of the sample of dry manna that we examined was approximately: Melezitose 75-83% Sucrose 2.9% Reducing Sugars 11.5%" Melezitose is an extremely rare trisaccharide of the formula C H O which on hydrolysis yields IS n2 16 ^ J J plucose and turanose, the latter is very difficultly hydrclyscd to glucose and fructose but in the con- ventional methods of sugar analysis, the only pro- duct of hydrolysis having direct reducing action is glucose. *The Occurrence of Melezitose in a Manna from the Douglas Fir, by C.

Ask the average Canadian to name our educa- tional institutions and it is scarcely likely that "Museums" would be included in the list. Ask a dweller in New York City the same question, and if he omitted "Museums" he would show that he failed to appreciate the advantages at his very doors. Modern pedagogy recognizes the importance of studying objects rather than the description of ob- jects; the modern museums display, in instructive and attractive manner, things gathered from the great and wonderful world around us. We have primary and secondary schools, and higher up are the colleges and universities, but museums include among their attending students the toddling infant, and the grey-haired patriarch. Let us consider some few of the things which great museums have to teach us. One of the newest as well as one of the greatest of the museums on this continent, is the American Museum of Natural His- tory, situated in New York City. Its exhibits are multitudinous and truly impressive. Who can view understandingly the wonderful mounted specimens of the reptilean monsters of the dim geologic past, without having a broader, more profound, more accurate view of the brief moment of time in which we live? Who can stand before those creations of art, the background bird groups, without having a better understanding and appreciation of the beauties of our b;rd life in its natural setting? Such work is as truly the work of the artist, as are paintings and statues! The wonderful array of minerals and the priceless collections of gems and precious stones il- lustrate the best that the rocks have to reveal. As wanderers from outer space, there are to be seen some of the largest meteorites known. Among them are included Peary's wonderful specimens from Greenland, one of which is as large as an ex- plorer's tent. And what of the National Museum at Washing- ton? Few will fail to recall the wonderful groups of American aboriginies, transfixed as it were near their habitations in the midst of their daily tasks, with their implements, and food supplies nearby ; nor can the fine groups of African game animals be forgotten, including rhinoceros, buffaloes and lions, collected by Colonel Theodore Roosevelt. From the Field Museum of Natural History, Chicago, the visitor carries away a better under- standing and clearer picture of African antelope, hyenas, zebras and leopards in their natural habitat than pages of descriptive writing could have given. The Milwaukee Public Museum takes the visitor back to the days of early colonial life in America, and depicts a street scene, say in Massachusetts, with small frame houses, homemade furniture, dove cotes, and people dressed in simple homespun. Fine groups of mammals and birds and many other ex- hibits are there, but the colonial village is unique. The New York State Museum at Albany illus- trates in wonderfully realistic form, the early fish- like creatures of the geologic past, and one of the earliest trees known from fossil remains. The Iroquois indian groups, prepared from indian models, under the direction of a Mohawk Indian, perpetuate the memories of Indian life as it was when Champlain was founding Canada. And there are other great museums at Pittsburg, Brooklyn, Boston, Philadelphia, and elsewhere, all teaching their lessons to the visitor. Volumes could be written descriptive of them, each writer depicting those exhibits which appeal to him most. It must not, however, be supposed that the public exhibits make up the entire museum, nor that all specimens are placed on exhibit. Great as is the popular educative value of exhibits, many specimens must also be preserved for comparison and study by specialists and research students. Zoological speci- mens generally fade when placed on exhibit, and groups of mammals, birds and insects have to be replaced by new material from time to time. So it happens that for every specimen on exhibit hun- dreds or in many cases thousands of valuable speci- mens may be carefully stored away, where they are available for study, or to replace other exhibits. Besides the exhibitions and the special researches carried on by modern museums, lecture halls are pro- vided, where members of the staff lecture to students from schools and colleges and to the public in general. So far reference has been made to the museums of the United States only; let us now turn to the museums of Canada. Among these are the pro- vincial Museum of British Columbia, at Victoria, the Banff Park Museum, the Redpath Museum of Natural History at McGill University, Montreal, the Museum of the Natural History Society of New Brunswick at St. John, the Royal Ontario Museum at Toronto, and the Geological Survey Museum housed in the Victoria Memorial Museum at Ottawa. The British Columbia Museum is particularly mentioned by visitors because it contains a complete collection of the game animals of the province. The Banff Museum appeals to tourists because of its April, 1919] The Canadian Field-Naturalist II game exhibits. The Redpath Museum contains a variety of collections, dating back over many years, and is a storehouse of valuable study material for McGill University. The Museum of the Natural History Society of New Brunswick, at St. John, emphasizes the direct instruction side of museum work, and, although possessed of limited resources, with the co-operation of the railways, places timely exhibits before the people by means of museum cars. The Royal Ontario Museum at Toronto has, within the last six or seven years, assumed the lead- ing position in Canada on account of its exhibits. It contains a number of very interesting features, among which are its collections of oriental arms and armor, its antique furniture and musical instruments and its well arranged collections of minerals and inverte- brate fossils. Our national institution, the Geological Survey Museum housed in the Victoria Memorial Museum at Ottawa, contains the exhibits long housed on Sussex street, including all the collections made by the Geological Survey since its founding by Sir William Logan in 1842. The collections of indian clothing, weapons, works of art, and utensils are very complete and fine, and could not be replaced. The herbarium represents collections from all parts of the country. The zoological collections contain specimens of most of the species of the vertebrate fauna of Canada and in some lines it is very com- plete. About 13,000 bird skins are catalogued and carefully stored for study, and the game and fur- bearing mammals are represented by many specimens. It is in palaeontology, hcwever, that the Geological Survey Museum ranks especially high. All the type specimens described by the noted Canadian palaeontologists, Elkanah Billings and J. F. Whiteaves (that is the specimens which were first studied and upon which the species were founded) are contained in the invertebrate collection, along with the types cf more recent workers, and thou- sands of valuable specimens gathered from all parts of Canada during 75 years of exploration. In vertebrate palaeontology, many line specimens re- present the huge creatures of past geologic ages, and the Cretaceous dinosaurs from the Red Deer Valley of Alberta form a collection second only to that of the American Museum of Natural History, New York. These were obtained during the past six years by the veteran collector, Charles H. Sternberg and his sons, and were being described by the late Lawrence M. Lambe. There are also the ores and minerals of Canada, of which we may be justly proud. Specimens have been collected from all parts of the country and a very good display of these is now being placed on exhibit in the economic museum of the Geological Survey, at 227 Sparks street. It IS not to be supposed, however, that because of the collections already made, that nothing is left to be done. A museum must be a growing concern like all other institutions that possess life and a future. Dr. W. T. Hornaday has said that the British Museum surpasses all other museums because a devoted nation has for generations collected tro- phies and specimens for it from all corners of the earth. It remains for Canadians to give their Museum such support that it may be made and kept, an object of sustained national pride. Specialists have been appointed to take charge of the various divisions cf natural history and a fair start had been made in arranging public exhibits when the Parliament Buildings were burned. The Museum building was needed for Parliament and all museum material had to be hurriedly packed and stored. Thus, so far as the public is concerned there has been no National Museum for the past three years. The preparation of exhibits has con- tinued but has been much curtailed by lack of space. Plans are ready however for placing many fine exhibits in the halls as soon as the building is once more made available for museum purposes. Let us picture to ourselves what the museum may some day be like. The Ethnological hall is intact and with its wealth of aboriginal material may be reopened on short notice. The hall of fos-^il verte- brates may be quickly rearranged, so as to display its huge reptilian monsters, early mammals, birds, and fishes altogether a suggestive chapter of the geologic past. The wonderful collection of fossil shell fish and other inhabitants cf the early seas when arranged according to formations and biologic groups will be one of the best assemblages of its kind in America. The contemplated bird group, repre- senting the avifauna of southwestern Ontario (the extreme southern tip of Canada), should fascinate all bird lovers. Musk ox, moose, polar bear, beaver and other groups of cur big game and fur bearing mammals are planned and some are partly executed. These with scenic backgrounds and natural acces- sories, should be a source of education and delight to all lovers cf nature, and to sportsmen especially. For the miner and mineralogist there will be systematic collections of minerals and rocks, models of mining camps, and maps and plans of mines. For the botanist there is the herbarium, for the entomologist the insect collections and so on. In short, with the specialists who are in charge and with the nucleus of a great collection already on hand, effective, popular support expressed through Parliament is all that is needed to make our museum in the near future something to be proud of, an educational institution, teaching effectively all branches of the natural history of Canada. 12 THE BIRDS OF SHOAL LAKE, MANITOBA. By p. a. Taverner. (Continued from page 164 of The Ottawa Naturalist, Vol. XXXII.) 103. *BLACK-BILLED CUCKOO, Cocc^zus eryhro- phihalmus. Job reports seeing this species on the western side of the lake on June 27 to 30, 1912. We saw none in 1917 though we heard rumors of cuckoos having nested in the vicinity. In 1918 the Black-bill appeared on June 14, after which Young noted a few birds almost daily to August 1. 104. BELTED KINGFISHER, CeT^le alcyon. Strangely enough, on the borders of such a fine lake we saw no kingfishers in 1917, though Young reports one on May 2, 1918. The Ward brothers say that in previous years there were always a few about, and Seton reports a specimen taken by Miller Christy on May 15, 1887. The only ex- planation of their present absence seems to be the lack of fish caused by the extreme akalinity of the lake at its present level. 105. ^HAIRY WOODPECKER, Dryohates villosus. Rather rare. Only two seen during the spring visit and one in September of 1917. Young noted the species, in 1918, in limited numbers, from June 3 to Sept. 26, taking juveniles but recently from nest, so it doubtless breeds in the vicinity. Five of our specimens are c learly referable to D. v. leucomelas though one, Sept. 22, 1917, falls slightly short of leucomelas measurements. 106. *DOWNY WOODPECKER, Dryohales pubescens. Several seen during the spring of 1917, but none in the autumn. Observed by Young in 1918 in small numbers from May 3 to Sept. 12. 107. ^YELLOW-BELLIED SAPSUCKER, Syphrapicus varius. Next to the Flicker the commonest woodpecker. Several nests were found and the species was still present during the fall visit in 1917 and to the end of September, 1918. 108. RED-HEADED WOODPECKER, MalanepTes eryihrocephalus. Though we have no substantiating evidence, the Ward brothers declare that they have seen one or two individuals. There should be but little mis- take with such a showy and strongly marked species. 109. "^FLICKER, Colapies auratus. Very common and breeding. Still present in 1918 to date of leaving Oct. 2. Young says that through September they were very busy feeding on ant hills. 110. ^NIGHTHAWK, Chordeiles yirginianus. Very common in 1917. First arrival May 18. One seen on Sept. 17, but none thereafter that year. The specimens taken seem to be virginianus. One is near!y light enough to be regarded as hesperis but as it can be matched by individuals from New Bruns- wick and central Ontario, I hesitate to so identify it. 111. "^RUBY-THROATED HUMMINGBIRD, Archi- lochus colubris. Quite common throughout the spring visit of 1918 ?nd noted bv Young occasionally in 1918 from June 1 to end of August. 1 12. """whip-poor-will, Anirosiomus vociferous. Heard in 1917 nearly every night during the spring visit and once in the autumn, on Sept. 17. Young only observed it once on June 6 in 1918, but his difficulty in hearing would prevent his noting it very often. 113. ^KINGBIRD, Tyrarmus tyrannus. First seen in 1918 on May 18; very common by the 29th. On Sept. 18 a flock of six were seen. Common in 1918 from May 17 to Sept. 10. 1 14. ^PHOEBE, Sayornis phoebe. One taken by Young, on Aug. 30, 1918, is our only record. 1 1 5. ^CRESTED FLYCATCHER, MyiaTchus crinitus. In 1917 only one was seen, June 1. In 1918, Young noted it twice in early June, three times in July, and once in September. The Ward brothers say that in 1916 Frank McGiifon took a set of eggs locally. 116. OLIVE-SIDED FLYCATCHER, Nutallornis borealis. In 1917 one reported on June 5 and one taken on ihe 14th. In 1918 Young noted several on June 4 to 9, and again a single bird on Aug. 17. 1 1 7. "^WOOD PEWEE, Myiochanes yirens. Our only record for this species consists of two specim.ens taken by Young on June 18 and July 2, 1918. The former is a female and had an egg ready to lay, thus verifying the species as a breeder in the locality. 118. "'"yellow-bellied FLYCATCHER, Empidonax flavlventris. One taken on Maple Island above the Narrows on May 30, 1917. As sight records unsupported by the ear are unsatisfactory in regard to the smaller flycatchers, citing the specimens taken by Young in 1918 is probably the better way of reporting his experience. He took specimens of this species on June 4 and Aug. 1 5. April, 19i9] The Canadian Fielx)-Naturalist 13 119. *TRAILl's flycatcher, Empidonax trailli. First seen on May 9, becoming almost common by the 1 4th. In 1918 Young took one on June 8. All specimens are referable to the Alder Flycatcher, E. t. alnorum. 120. ^LEAST FLYCATCHER, Empidonax minimus. In 1917 first seen on May 23. By the 30th they were common in all the bluffs. Young's experience in 1918 seems about similar. He took specimens from May 30 to July 31. 121. ^HORNED LARK, Oiocoris alpesiris. In 1917 very common during the spring visit, but only a few present in the autumn. In 1918, Young found them consistently common throughout his stay from late April to early October. On April 24 he found a large flock (100) in company with Lap- land Longspurs. He obtained one specimen from it, a well-marked O. a. alpestris. All other birds taken are O. a. praticola. It is worth while noting, as a caution against taking assumed breeding dates as evidence of nesting, that only six days after the taking of the above evident migrant alpesiris nearly fully fledged young of praticola were col- lected. Thus local biids had young out of the nest before more northern nesters had left for their breeding grounds. 122 MAGPIE, Pica pica. The Ward brothers say that the Magpie occas- ionally occurs about Shoal Lake. They recall one seen in July and two in June, 1904. May 21, 1918, William Ward reported seeing one near camp, and a few days later Frank Ward had exceptional op- portunities of watching another at Gimli on the shores of Lake Winnipeg, some forty miles east of us. 123. BLUE JAY, C\^anocilta cristata. In 1917 fairly common in spring but not noted during the autumn visit. In 1918 Young noted the species until Sept. 28. 124. CANADA JAY, Perisoreus canadensis. Said by the Ward brothers to be a winter visitor, coming sometimes as early as September, but less numerous of late years. 125. RAVEN, Corvus corax. Said by the Ward brothers to be fairly common during hard winters. 126. ^AMERICAN CROW, Corvus hrachyrhynchos. Very abundant. Residents do not complain much of its destructiveness to crops but it is certainly a great nest robber and its effects upon the ducks must be marked and serious. Amongst Young's speci- mens are two that he concluded from their actions to be mated, but, while the male is large even for C. h. brachyrh\)nchos, the female falls well within the measurements for C. b. hespris. Considering other Canadian prairie specimens with these, I do not consider the two races satisfactorily differentiated. 127. ^BOBOLINK, Dolichonyx oryzivorus. In 1917 a few were seen on wet meadows in the spring, none in the autumn. In 1918 Young noted them from June 8 to Aug. 22. The residents say that occasionally they do some damage to grain. 128. *COWBIRD, Moloihurus ater. Very abundant. Noted by Young in 1918 to Sept. 7. 129. *YELLOW-HEADED BLACKBIRD, Xanthoce- phalus xanthocephalus. The least common of the resident blackbirds. Oc- casional small flocks were found foraging here and there on the uplands, cultivated fields and dry marshes. In 1918 still scarcer than during the pre- ceding season. It seems that this bird requires more extensive marshes than the Red-wing. In 1917 we found resident colonies in a few places while the Red-wings occupied every reedy slough. Young reports no breeding birds in 1918. His latest re- cord for the species is Aug. 26. The juveniles in first winter plumage are quite similar to the adults but the white primary coverts are reduced to traces and the crown and hind neck concolorous with the back. In one specimen, a stripped plumage, similar to that of the juvenile Red-wing is just disappearing on the breast where it is being replaced with yellow of rather a deeper orange than that of the adult. 130. *RED-WINGED BLACKBIRD, Agelanius phoeniceus. Very abundant, breeding in every suitable locality. The A. O. U. Check List recognizes the Red- winged Blackbird of central North America as the Thick-billed Red-wing, A. p. fortis. This race Mr. H. C. Oberholser (Auk XXIV, 1907, pp. 332- 336) further divides into northern and southern forms, calling the Canadian race A. p. arctolegus, extending its range east to Isle Royal, Lake Super- ior, and restricting fortis to the United States, south from Nebraska. As the A.O.U. Committee has not as yet recognized arctolegus, from the standpoint of the Check List, it can be regarded as a synonym of fortis. The diagnosis for fortis calls for a larger bird than phoenicus, the eastern race, with a com- paratively shorter, thicker bill. Arctolegus is char- acterized by its describer as a large phoeniceus with slight color differences in the female. To obtain easily compared factors of shape and size, I have divided the length of the bill by the depth for an index of shape and multiplied them together for an index of size. The former gives the length in units of depth, and the latter a pro- duct that whilst more or less arbitrary in itself, when derived from specimens of the same species, should be strictly comparable with each other and representative of relative size, irrespective of the disturbing element of shape. 14 The Canadian Field-Naturalist [Vol. XXXIII. Comparing Shoal Lake birds with other material, I have made use of the following adult male mater- ial: 9 from Mass., southern Ont. and southern Mich. ; 7 from Shoal Lake and two from Douglas, Man.; and 7 from Sask., Alta., and Mack. The measurements of these birds together with those sim- ilarly derived from Mr. Oberholser's paper above cited, tabulate as follows: Index Index Wing Wing shape, size, average. Min. & Max. 9. Eastern Canada. 1.9 24.5.1 121.7 (116.0-128.0) 7. Manitoba 1.96 264.1 124.4 (120.5-128.0) 7. Sasic.. Alta., Mack 1.8 229.2 127.2 (111. .5-132. .5 ) 10. plioeniceus (H.C.O.) 1.8 269.2 118.8 (114.0-122.0) 12. arctolegus (H.C.O.) 1.88 304.8 125.4 (121.5-130.0) 11. fortis (H.C.O. )_- 1.88 254.04 129.7 (125.0-134.0) In color, I find Shoal Lake females showing a slightly greater amount of white below, most dis- tinctly on the throat and upper breast, but the dis- tinction is too slight and inconsistent for certain or individual recognition. It will be seen that the difference in shape of the bills of these various strains is very slight, and in no case marked enough to warrant the title "Thick- billed", in fact Oberholser's arctolegus and fortis have more slender bills than phoeniceus, and the Shoal Lake specimens considerably exceed all others in this direction having minimum and maximum in- dices of 1.72 and 2.22. It is also evident that whilst there is a slight in- crease in size of both bill and wing of this species westward over the prairie provinces, the difference is not so marked in the new material as in Ober- holser's measurements: also that individual variation is almost as great as the racial distinction and is one of averages, leaving the bulk of individual specimens subspecifically unrecognizable by character. Such distinctions do not in the view of the writer form criteria sufficient for systematic separation and nomenclature. Irrespective of such judgment on the races concerned it is evident that these Shoal Lake birds are just about intermediate between east- ern and v/est plains birds though personally I do not care to separate them from phoeniceus. 131. '%ESTERN MEADOW LARK, Sternella neglecia. Very common during all visits. The song of the Western Meadow Lark is justly noted. It is one of the most wonderful prairie sounds and its con- stant repetition and infinite variety is characteristic of the west. However, eastern ears may be par- doned for a little disappointment on first hearing it. If they expect to hear a glorified eastern Meadow Lark song they certainly will be disappointed. While it is a beautiful production it is not the song they have been accustomed to associate with the coming of spring. It has many charms of its own, but they are not familiar; in fact hardly a note suggests the well remembered voice of the old eastern friend and until its source is traced, even an experienced orn- ithologist is apt to wonder as to the identity of the singer. It will, I think, take several seasons' exper- ience with this species to build up a new set of associations and take it to the heart in place of the well beloved eastern harbinger of spring. 132. ^BALTIMORE ORIOLE, Icterus galbula. In 1917, arrived on May 23, common on June 2; not seen in the autumn. In 1918, arrived on May 16, the bulk disappeared on July 23, and the last one was seen on Aug. 6. 133. ''^RUSTY BLACKBIRD, Euphagus carolinus. Not recognized in spring, but one was noted on Sept. 21, 1917; not recorded by Young in 1918. 134. ^brewer's blackbird, Euphagus cyanoce- phalus. Very amundant and nesting in nearly every open bluff. They follow the ploughman about his work gleaning from the newly turned furrow, and as- sociate commonly with the sheep perching upon their backs and scrutinizing the fleece, probably for ticks. On Sept. 25, 1917, three were taken from a flock. Of these one female, seemingly an adult by its completely granulated skull, had the iris red- dish-brown just flecked with straw. All other specimens taken had the usual straw-colored iris. 135. ^BRONZE crackle, Quisculus quiscula. In 1917 there was a thriving colony of Bronzed Crackles nesting in the willows just behind the Ward house until persevering work with a shot gun removed them, after which many more attractive birds of less questionable character were able to appropriate the premises. The Wards accuse them of domg considerable damage by killing young chicks. While I cannot substantiate this charge I have little doubt as to its truth. None were seen in the autumn of 1917, but Young noted the species as late as Sept. 27, in 1918. 136. ^'EVENING GROSBEAK, Hecperiphona vespcr- iina. In 1917 we saw two to four individuals. May 20, 24 and 25, and secured several specimens. I noted that the bills of these were as green as those of summer birds from British Columbia and quite different from the yellow mandibles of eastern mid- winter specimens. The difference is probably sea- sonal rather than subspecific. Unfortunately these are amongst the birds that were lost. In 1918, Young noted three and two Sept. 25 and 30. 137. '^PURPLE FINCH, Carpodacus purpureus. None noted during either spring. Two or three were seen on several days in a small growth of hawthorn in September. In 1918, Young noted small numbers from July 1 1 to Aug. 26, and a single individual on Sept. 25. April, 1919] The Canadian Field-Naturalist 15 138. ^GOLDFINCH, Asiragalinus Irisiis. None seen in spring until May 27, 1917, after which they became common and were still num- erous in September. Young noted them in 1917 from April 29 to his departure on Oct. 2. 139. *PINE SISKIN, Spirtus p'nus. In 1918 Young noted 5 on June 5, 2 on the 21st, and one Sept. 24, taking specimens on the first two occasions. 140. *SNOW BUNTING, Plectrophenax nivalis. In 1918, Young found large flocks on his arrival on April 24, and saw them almost daily until May 24. After this, 5 were noted on the 22nd and one on the 28th. Specimens taken on April 21 and May 2 are in high breeding plumage. 141. ^LAPLAND LONGSPUR, Calcarius lapponicus. A few seen between May 22 and 25. Very abundant in the autumn, occurring in large flocks in the long grass of the old marshes and on the lake shore. In 1918, Young found large flocks on April 24, but the bulk of the species left after the 30th. One straggler was taken on June 4, In the autumn the flocks of the previous year were absent and he noted but one individual on Sept. 23. 142. ^CHESTNUT-COLLARED LONGSPUR, Calcarius ornaius. A single bird secured on June 6, 1917, and a flock of seven noted on the 9th. It was not seen by Young in 1918. Seton has a specimen taken by Miller Christy in May, 1887, but the Ward brothers are not familiar with it, and it is doubtless rather rare in the locality or very local in distribution. 143. ^VESPER SPARROW, Poocaetes gramineus. Strangely absent both springs in the vicinity of the lake though from the train one was seen a few miles south of Erinview. In the autumn of both years they were seen about the Ward house in limited numbers between Aug. 23 and Sept. 28. These birds are rather large for the eastern race, and though in rather indeterminate juvenile plumage can probably be referred to the western race P. g. confinis. 144. ^SAVANNA SPARROW, Passerculus sand- fvichensis. Very common indeed during all visits. The local breeding birds show the bright yellow eye-brow common to the birds of the prairie provinces, and certainly do not agree with the described characters of P. s. alaudinus and at present seem without a name. The autumn birds are slightly darker than savanna and are both with and without the yellow loral spot. I suspect that both a resident and a migrant form are represented, but I do not care to refer them to any sub-species generally accepted at present. 145. baird's SPARROW, Ammodramus bairdii. Though reported by Chapman as very common at Shoal Lake and by Seton as common and breed- ing, the species was carefully searched for both seasons without success. Undoubtedly it has de- parted from the country with the lowering of the lake level and the disappearance of the broad marshes. 146. ^LECONTe's SPARROW, Passerberbulus lecontei. Scattered individuals were met with both seasons in widely separated localities both in spring and in autumn. 147. ^nelson's SPARROW, Passerberbulus nelsoni. The western form, the Prairie Sharp-tailed Sparrow, P. n. nelsoni was met with in scattered individuals in various parts of the surrounding coun- try as late as September 25. The juvenile plumage is quite different from that of the adu't and might well be taken for a different species. All strong ochre, slightly paler below and only broken by restricted fuscous centres of second- aries and wing coverts which become fainter and almost concealed across the back, a double crown stripe and a faint bar back from the eye. The outer web cf the first primary is edged with clear cream and the tail is ochracecus-fuscous with dark shaft. One specimen shows adult plumage appearing in the juvenile dress indicating that full plumage is assumed the first winter. 148. ^Harris's sparrow, Zonolrichia querula. Very common on our first arrival in 1917. Most of them left about May 28, though a couple of individuals remained to the end of our stay. Frank Ward reported seeing one carrying nesting material from his chip-yard towards the nearby bluff and suspected that they were nesting in the locality. The same authority tells us that some years ago he found a nest of this species on the ground in the shelter of an old log. On the return visit the same autumn they were common again in their old spring haunts and I was informed that individuals had been noted regularly through the summer. With this possibility of finding breeding birds. Young watched carefully for them during the summer of 1918, but between May 28 and Sept. 14 none were noted. They returned on Sept. 14 and were still present when he left on Oct. 2. The most peculiar thing about these autumn birds was the unusual abundance of adults in comparison to juven- iles. Of perhaps fifty birds seen but three or four were juvenile either by plumage or cranial char- acters. This is unusual enough amongst autumn birds to justify special mention, as usually juveniles greatly outnumber adults. 149. *WHITE-crowned sparrow, Zonolrichia leucophrys. In 1917, single individuals seen on May 15 but 16 The Canadian Field-Naturalist [Vol. XXXIIi. common throughout the autumn stay. In 1918, present in limited numbers from May 6 to May 23 and rather more numerous Sept. 1 7 to 30. Of those in adult plumage, two males (May 13, 1918 and Sept. 20, 1917) have the white loral line continuous to bill and can therefore be ascribed to Z. I. gambeli. The other has it faintly interrupted across the lores and must therefore be regarded as intermediate be- tween Z. I. leucophrys and gambeli. 150. white-throated sparrow, Zonotrichia albicolUs. Common both spring and autumn. In 1918, absent from May 27 to Sept. 8, except four in- dividuals seen on July 24. Great numbers seen Sept. 19-27, but still present when Young de- parted on Oct. 2. 151. *TREE SPARROW, Spizella monticola. Not noted in 1917. In 1918 observed Iron: April 26 to May 4, and again on Oct. 1 and 2. One specimen, female, April 30, I refer to 5. m. monticola. 1 52. ^CHIPPING SPARROW, Spizella passehna. Very common in the spring of 1917. To the end of May flocks of a hundred or more were met. In the autumn the species was not certainly identi- fied though the first day of arrival I thought I recognized them amongst the hordes of clay-colored sparrows. In 1918, Young noted a few on May 4 and 8. From the 16th to 27th it was present in flocks of from 50 to 100. The species departed on June 8 and no more were seen except 3 on July 23. 153. ^CLAY-COLORED SPARROW, Spizella pallida. Very common in spring and autumn. In 1917, they seemed to leave on Sept. 21, but in 1918, Young noted them to the date of leaving on Oct. 2. 154. ^SLATE-COLORED JUNCO, Junco h^emalis. In 1917, but one specimen seen in the spring but fairly common in the autumn. In 1918, Young noted it from April 24 to May 1 5 and from Sept. 6 to Oct. 2. 155. *SONG SPARROW, Melospiza melodia. Common in spring and autumn of both years. In 1918, present on arrival, April 24, and when leav- ing, Oct. 2. Specimens taken between May 13 and July 31, probably breeding birds are the slightly lighter form, with more distinct markings, than eastern M. m. melodia and I refer them to M. m. juddi. 156. ^Lincoln's sparrow, Melospiza lincolni. In 1917, single individuals seen and taken on May 19 and June 1. In the autumn seen nearly daily in limited numbers. Noted in limited numbers by Young in 1918 from May 11 to 25 and more commonly from Aug 3 to Oct. 1. 157. *SWAMP sparrow, Melospiza georgiana. Seen in small numbers in the spring of 1917 and more commonly in the autumn. In 1918, Young noted it from May 4 to 30 and again Aug. 21 to Oct. 2. Strangely enough but one bird was seen in the summer, June 10, which seems to indicate that the species does not breed in the locality. 158. %0X SPARROW, Passerella iliaca. One specimen taken Sept. 22 is all that was seen in 1917. In 1918, Young noted single individuals on Sept. 16, 24 and 30, and a flock of 30 on the 25th. 1 59. ^TowHEE, Pipilo eryihropthalmus. In 1917, fairly common in the spring and still present Sept. 19 and 21. In 1918, Young saw a few individuals with general regularity from May 24 to July 29. A single bird, Aug. 13, and another Sept. 19. 160. ^ROSE-BREASTED GROSBEAK, Zamelodia ludoviciana. Fairly common during the spring visit in 1917. In 1918 observed irregularly from May 16 to Aug. 5. 161. ^PURPLE MARTIN, Progne subis. A few seen daily in 1917, probably the same ones. A few occupied a box near an adjoining summer cottage and another colony was found nest- ing according to aboriginal habit in a hollow tree a few miles from camp. In 1918, noted by Young from May 17 to Sept. 20. 162. *CLIFF SWALLOW, Peirochelidon lunifrom. In 1917 a few seen daily with the flocks of Barn Swallows about camp and occasional birds else- where. Seton noted twenty-five nests on a barn in 1891. In 1918, noted from May 24 to Sept. 17. 163. ''^BARN SWALLOW, Hitundo erylhroga&ier. Small colonies occupy most of the farm building groups in the neighborhood. In the autumn of 1917 this was the only swallow seen. In the chilly morn- ings a small flock of them would be found warming themselves on the sunny roof of the house where the frost was melting. As soon as the day warmed they disappeared over the meadows and rarely re- turned until the next morning. The last seen were on Sept. 21. In 1918, they remained common until Sept. 20. 1 64. *TREE SWALLOW, IridopTocne bicolor. In 1917, only a few seen each day in spring and none in the autumn. In 1918, they remained com- mon until Aug. 21, but a few were seen thereafter until Sept. 1 7. 165. *BANK SWALLOW, Riparia riparia. A few observed daily in the spring of 1917. The Ward brothers say that one stage of the lake left numerous steep banks five to six feet high and that swallows nested in these in great numbers. Now April, 1 91 9] The Canadian Field-Naturalist 17 these banks are far removed from the water, cut down by cattle and sheep, and are deserted by the birds. We saw no nesting places in the vicinity. Young noted it in 1918 only in autumn, arriving on Aug. 17, and seen in small numbers irregularly until Sept. 12. 166. '^CEDAR WAXWING, Bomhycilla cedroTum. In 1917, a flock of a hundred or so seen on May 1 1 and smaller lots daily thereafter through the spring visit but not noted in the autumn. In 1918, the species was first seen on June 4th and irregularly observed until Sept. 26. 167. ^LOGGERHEAD SHRIKE, Lanius ludovicianus. In the spring of 1917 we found two breeding pairs and a single individual. I can find little foundation for Ridgeway's color distinction, "de- cidedly paler" of the White-rumped Shrike, L. I. exubitorides. Prairie birds are very slightly paler than L. m. migrans from eastern Ontario. The dif- ference can only be observed by the closest com- parison. In the four specimens taken at Shoal Lake the rumps are intermediate between that of eastern birds and excubitorides from Alberta. I, therefore, regard them as intermediates between these rather poorly defined races. 168. ^RED-EYED VIREO, Vireos^lva oUvacea. In 1917, not seen until May 30 after which oc- casional birds were noted. Not seen that autumn. In 1918, Young noted the species continuously, in fair numbers from May 17 to Sept. 16. 169. ^PHILADELPHIA VIREO, Vireosylva Philadelphia. Not noted by us in 1917, but Seton has a speci- men in his collection taken at Shoal Lake by Miller Christy on May 20, 1887; Young collected specimens on the following dates in 1918, May 21 and 24, June 1 and Sept. 24. 170. ^WARBLING VIREO, Vifeosylva gilva. In 1917, quite common after May 28. In 1918, Young found it constantly present in fair numbers from May 20 to Sept. 26. All specimens are V. g. gilva. 171. Solitary vireo, Lanivireo solitrius. Not noted by us in 1917, but seen by Young in 1918 from May 10 to 20 and Sept. 2 to 16. 172. '^^BLACK AND WHITE WARBLER, Minotilta varia. In 1917, occasional individuals seen after May 30 in spring and one on Sept. 19. In 1918, Young noted it with fair regularity, but scarcer in July, from May 8 to Sept. 26. It probably breeds. 1 73. ^NASHVILLE WARBLER, VermivoTa ruhri- capilla. Not noted in 1917 but reported by Young in 1918 to be very common in May and September. Noted May 18 to June 20 and Sept. 2 to 26 with occasional individuals through July. 174. "^ORANGE-CROWNED WARBLER, VermivoTa celala. In 1917, seen the first two days of our spring visit and on Sept. 19. In 1918, Young noted it only from May 17 to 24. In specimens obtained the yellow is slightly lighter than in comparable eastern species, but as this is probably due to the cleaner and better condition and make up of the skins, I regard them as V. c. celala, the geographical probability. 175. "^TENNESSEE WARBLER, Vermivora peregrina. Not noted in 1917, but reported by Young in 1918 to be very common in May and September. Noted May 18 to June 24 and Sept. 2 to 26 with occasional individuals through July. 176. '='CAPE MAY WARBLER, Dendrioca tigrina. Two taken at Maple Island on May 30, 1917, and noted by Young on May 21 to 24, 1918. 177. ^YELLOW WARBLER, Dendroica aesiiva. In 1917, a few present on our arrival on May 17 but common after June 1. In 1918, common from May 8 to Sept. 16. Compared with the writer's experience with this species in southern Ontario this is a very late stay for the species as in the Lake Erie neighborhood Yellow Warblers are rarely seen after Sept. I. 178. "^MYRTLE WARBLER, Dendroica coronata. In 1917, the commonest Warbler on both visits. In spring i; disappeared abcui June 1, after which but occasional individuals were seen. 1 79. "^MAGNOLIA WARBLER, Dendroica magnolia. In 1917, rather scarce in spring. In 1918, on the contrary. Young found it quite common from May 16 to the 27th and in the late autumn from Sept. 2 to 28. 180. ^CHESTNUT-SIDED WARBLER, Dendroica pensylvanica. Individuals seen June 4 and 5 and on Sept. 17. Not seen by Young in 1918. 181. *BAY-BREASTED WARBLER, Dendroica caitanea. In 1917, only seen on June 2 and 6. In 1918, only noted on Sept. 6 to 12. 182. *BLACK-POLLED WARBLER, Dendroica striata. In 1917, first seen on May 30. Quite common on June 2, and but occasional individuals thereafter. One seen on Sept. 1 7. 183. ^BLACKBURNIAN WARBLER, Dendroica fusca. One taken by Young en May 16, 1918, is our only record. 184. *BLACK-THROATED GREEN WARBLER, Dendroica virens. Individuals seen by Young on May 24 and Sept. 4, a specimen being taken on the latter date. He also reports the remains of another impaled by shrikes without giving date. 18 The Canadian Field-Naturalist [Vol. XXXIIL 185. '^PALM WARBLER, Dendroica palmarum. In 1917, present in limited numbers on our ar- rival but none seen after May 25. Several seen between Sept. 19 and 22. In 1918, noted by Young from May 8 to 30 and Sept. 6 to Oct. 2, the date of departure. 186. ^OVENBIRD, Seiurus aurocapillus. In 1917, a few^ single individuals v^ere heard and seen in the deeper woods from May 29 on. Be- fore leaving they become slightly more common. In 1918, noted by Young from May 21 to June 3, one individual in July, and then again from Sept. 2 to 14. This is a retiring species and oftener recognized by ear than sight. Its absence through June, July and August is probably more apparent than real. 187. ^NORTHERN WATER THRUSH, SeiuTus nove- boracensis. In 1917, two water thrushes were seen, perhaps an original pair. May 18 and June 2, in the dry willow grown creek bed by the Ward house. On Sept. 19 another was noted in the same locality. In 1918, the species was noted with daily regularity from May 10 to 25 and Sept. 4 to 26, with a single individual on Aug. 22. The specimens are in a very mixed lot of plumages, and one a male, Sept. 12, is nearly as white below as a Louisiana Water Thrush, 5. motacilla ; two other specimens are nearer the eastern one S. n. noveboracensis than S. n. notabilis. Three others while yellower below and blacker above and characteristic notabilis are quite comparable with some New Brunswick birds. I find that Grinnell's Water Thrush rests UDon very inconstant characters. 188. ^CONNECTICUT WARBLER, OpOTornis agiUs. On June 4, 1917, one bird was seen under ex- cellent conditions for determination, when shot it fell far away in heavy brush and could not be found. One juvenile was taken by Young on Sept. 16. 189. ^MOURNING WARBLER, OpoTotnis Philadelphia. Several times in the spring of 1917 I thought I heard this bird in a slashing in the oak patch in the big bluff behind the camp. It kept so close to a limited locality that I have no doubt that it was nesting nearby. It was absolutely identified June 14 when secured. In 1918, the species was noted by Young from May 30 to June 8 and one was taken Sept. 7. Specimens of this species in fall plumage are rather scarce in collections as it usually drifts through very inconspicuously early in the autumn. 190. ''^MARYLAND YELLOWTHROAT, Ceothlypis trichas. Quite common after June 2. In the autumn in- dividuals were seen Sept. 21 and 22. The species obtained are referable to G. /. occidentalis, the Western Yellow Throat. The backs are faintly lighter than eastern and intermediate between them and individuals from Indian Head and Edmonton, but the white foreheads are decidedly more extensive than in eastern species. 191. "^Wilson's warbler, Wihonia pusilla. Only seen in 1918 on May 18. In 1918, Young observed the species on May 16, 18 and 24. 192. "^CANADIAN WARBLER, Wilsonia canadensis. One taken on June 6, 1917, and noted by Young on May 24 and June 4. 193. "^REDSTART, Setophaga ruticilla. Not seen in 1917 until May 29, but common thereafter. In 1918, Young observed it from May 18 to June 8 and from Aug. 26 to Sept. 27. He did not note it through the summer. 194. "^AMERICAN PIPIT, Anthus rubescens. In 1918 fairly common during the early days of our spring visit along the lake shore, but none seen after May 30. Abundant in the fall occurring in large flocks, scattered bunches and individuals on all bare ground. In 1918, noted by Young on May 13 and 27 and Sept. 14 to date of departure Oct. 2. 195. "^sprague's pipit, Anthus spraguei. Between June 5 and 9, 1917, I was much puzzled by an oft repeated and haunting bird song that could be barely heard and which I was unable to locate or recognize. It was a fine silvery gradually de- scendmg Ree-ree-ree-a-ree-a-ree-a-aree-aree of about eight notes, and an octave in range. It had a peculiar ringing jingle like the Veery but mere sus- tained and regular. After innumerable futile at- tempts at discovering the singer at last I found it high over head flying about in circles for minutes at a time. It beat its wings vigorously against the slight breeze, making altitude rather than headway, and then the song came down. After the first two or three syllables reached the ground the wings fixed and the bird would sail in a downward spiral through the remainder of the song. This was re- peated time and time again. It took considerable patience to watch the little vocalist until it came down to earth by an almost straight dive. Though nearly out of sight in the air the speed with which it dropped and the distance away at which it alighted indicated that it was originally up no more than a hundred yards or so while singing. Thereafter we could hear this song nearly the whole of every fine day, but this was the only bird of the species that we met. In 1918, Young reports the species oc- casionally throughout the summer from June 21 to Sept. 7. 196. ^CATBIRD, Dumatella carolinensis. Common, found in nearly every bluff. In 1918, Young noted it almost daily from May 20 to Sept. 11. April. 1919] The Canadian Field-Naturalist [^ 197. %RO\VN THRASHER, Toxostoma rufum. Fairly common. At least two pairs lived within hearing of cur camp in 1917 and we met with half a dozen more on our spring rambles. In 1918, Young noted it constantly from May 16 to Aug. 24 with a couple of late individuals on Sept. 12 and 17. 198. '^HOUSE WREN, Troglodytes aedon. Very abundant and heard singing everywhere. They do not seem as inclined to build about the farm buildings as the species does in the east. There were innumerable possible nesting places about the farm- steed that few eastern wrens could resist yet none of them were occupied. A few individuals were still present during the autumn visit. In 1918, Young noted it continuously and regularly from May 10 to Sept. 30. Specimens are distinctly T. a. parl^mani. 199. 'WINTER WREN, N annus h'.cmalis hiemalis. Not seen in 1917, but in 1918 \ oung observed single individuals from May 20 to 23,. and on Sept. 16. 200. "^SHORT-BILLED MARSH WREN, Cislotlwrus stellaris. Not uncommon in certain localities. While usually inhabitating damp marshes some were found in dry grass or even in brushy edges in typical House Wren ground. None were certainly recognized in the fall of 1917 though Young lists it occasionally from June 1 to Sept. 25. 201. ''^LONG-BILLED MARSH WREN, T elmaiodyies palustris. Hardly commoner than the Short-bill and not so widely distributed. This species requires wetter and more extensive swamps than that species and the drying up of the marshes would more severely limit its habitat. A Marsh Wren glimpsed on the shore of a small pond on Sept. 19, 1917, was supposed to be of this species. Owing to their more restricted habitat the Long-biiled Marsh Wren was, in 1918, even scarcer than the previous year. Young only records occasional individuals May 7 and June 10. Specimens show the light back, and brown rather than black head of T . p. iliacus. 202. ='"BROWN CREEPER, Cerlhia familiaris. Young took two specimens of the Brown Creeper on Sept. 23 and 26, 1918. 203. ^"red-BREASTED nuthatch, Sitta canadensis. One individual seen by Young on Sept. 24, 1918. 204. '*^black-capped chickadee, Penihestes airicapillus. Only seen in 1917 on May 20 and Sept. 26. Of the former one female was taken with an egg in oviduct ready for deposition. Scattered individuals noted by Young throughout the summer of 1918. Specimens taken have constantly longer tails than any but extreme eastern specimens and hence are referred to P. a. sepientr'ionalis. 205. "^RUBY-CROWNED KINGLET, Regains calendula. In 1917, single individuals seen May 20 and June 1. In September a few were seen nearly every day. In 1918, noted by Young daily from May 7 to 24 and Sept. 9 to 30. 206. ^Wilson's thrush, Hylocichla fuscescem. Common. Its golden chain song could be heard every evening from our camp. In 1918, Young re- corded it nearly every day from May 9 to Sept. 28. All specimens show the slightly olive back of the Willow Thrush, H. f. salicicola. 1^1. "^Alice's thrush, H\)locichla alkiae. Thrushes of this genus were fairly common during migrations, but the bush was generally so dense and the birds so shy that collection gave the only certain separation between Alice's and Olive-backed Thrushes. I was fairly certain that we had speci- mens of both in the spring collection of 1917, but they all were lost in transit. One specimen taken by Young on Sept. 19 belongs to this species. 208. *0LIVE-BACKED thrush, Hylocichla ustulata. In 1918, Young noted thrushes under this head- ing from May 15 to June 1 and Sept. 6 to 20. All his specimens except one mentioned under previous heading are of this species which is probably the more common. We have specimens of the following dates: juvenile and adult males Sept. 18, 1917, Sept. 6 and 9. 1918; and juvemle females Sept. 9, 1918. These four are slighlty but consistently more oliva- ceous (or grayer) above and rather more heavily spotted on breast than comparable eastern H. u. sn>ainsoni differing from them almost as much as the Willow Thrush, H. f. salicicola differs from the Veery, H. f. fuscescens. I find these same distinctive characters in an autumn specimen from as far west as Jasper Park but not in spring and summer birds from intermediate points. These specimens agree closely with the description and range of H. u. almae Oberholser, and if every per- ceptible difference is regarded worthy of a separate name this form probably has claim to reinstatement in the Check List. 209. ^HERMIT THRUSH, Hylocichla guttata. Quite common during the spring of 1917. The last specifically recognized was on June 2. In the autumn one was taken on Sept. 19. In 1918, Young noted the Hermit Thrush from May 13 to 24 and Sept. 3 to 30. These are of course eastern Hermit Thrush, H. g. pallasii. 210. ^AMERICAN ROBIN, Planesticus migratorius. Common on all visits, in 1918, at date of de- parture, Oct. 2. 21 1. ^BLUEBIRD, Siala sialis. Though not known by the Ward brothers as a 20 The Canadian Field-Naturali3T [Vol. xxxiii. bird of the locality, we took a pair in 1917 on May 28, and later some six individuals were seen at var- ious times in the neighborhood. In 1918, Young saw 2 and 7 birds on June 24 and 25. On Oct. 2 as he was leaving there was a migrational wave of the species and he lists 50 for that day. This suggests that far from Shoal Lake being the most northern extremity of the species range here there is a habitat beyond that is occupied by them in considerable numbers. The species is apparently spreading into this country. ADDENDA. Since the publication of the earlier parts of this paper the following published data on the birds of the locality have been called to my attention in Recent Bird Records for Manitoba by E. T. Seton, Auk, XXV, 1908, pp. 450-454. 20. (anlea) BLACK DUCK, Anas ruhripes. Mr. Seton here reports another Shoal Lake specimen of this species in his collection taken by Geo. H. Meacham in 1901 who reports "two or more were shot at Shoal Lake in 1899". 28. (aniea) WOOD DUCK, Aix sponsa. Seton says: "G. H. Meacham reports it rare at Shoal Lake, but one or two are seen there each year". 212 LEAST BITTERN, Ixohrychus exiUs. Seton says: "Frank M. Chapman saw one at Shoal Lake, June, 1901". BRIEF REPORT OF THE OTTAWA FIELD-NATURALISTS' CLUB FOR THE YEAR ENDING MARCH 18, 1919. The fortieth year of the existence of The Ottawa FieM-Naturalists' Club has been the most successful in the recent history of the society. The club activities are directed toward popularizing and diffusing knowledge of the natural sciences, and have been carried on in three chief ways: a course of lectures, two series of field excursions, and the publication of The Ottawa Naturalist. The club membership now numbers 540. Twenty- cne members serving overseas have been carried gratis. The lecture programme consisted ot seven sched- uled lectures and a special lecture on wild geese by Mr. "Jack" Miner, of Kingsville, Ontario. The lectures are planned to create a more intelligent interest in Canadian natural history, and to give a better understanding of the value of scientific work. The field excursions were well patronized, especially the spring series at which the attendance averaged 38. Weather conditions reduced the at- tendance at the fall series. The spring series con- sisted of five outings and the autumn series of three outings. Scientific men attended the excursions to direct interest and answer questions. The Ottawa Naturalist, the official organ of the Club has been enlarged in dimensions and im- proved in material qualities and by the introduction of a cover design, more illustrations and more articles of Dominion-wide interest. At the request of several natural history societies of the Dominion, a plan of affiliation has been ar- ranged, the magazine of The Ottawa Field-Natur- ahsts' Club to be the medium of publication. The officers and committees for the year 1919 are as follows: President, M. Y. WiUiams; Vice-Presidents, L. D. Burling, P. A. Taverner; Secretary, Clyde L. ' Patch; Treasurer, F. W. Waugh; Editor, Arthur Gibson. Additional members of Council: Hoyes Lloyd; W. T. Macoun, G. A. Millar, R. M. Anderson, J. M. Macoun, Miss M. E. Cowan, Miss Crampe, C. B. Hutchings, C. M. Sternberg, H.

The organization meeting of the American Society of Mammalogists was held in the New National Museum, Washington, D.C., April 3 and 4. 1919, with a charter membership of over two hundred and fifty, of whom sixty were in attendance at the meeting. The following officers were elected: President, C. Hart Merriam (Washington) ; First Vice-President, E. W. Nelson (Washington) ; Second Vice-President, Wilfrid H. Osgood (Chi- cago) ; Recording Secretary, H. H. Lane (Okla- homa) ; Corresponding Secretary, Hartley T. H. Jackson (Washington) ; Treasurer, Walter P. Taylor (Washington). The Councilors are: Glover M. Allen (Cambridge) ; R. M. Anderson (Ottawa, Canada); J. Grinnell (Berkeley); M. W. Lyon (Washington); W. D. Matthew (New York); John C. Merriam (Berkeley) ; Gerrit S. Miller, Jr., (Washington) ; T. S. Palmer (Washington) ; Edward A. Preble (Washington) ; Witmer Stone (Philadelphia); and N. Hollister (Washington), Editor. Committees were appointed on: Life Histories of Mammals, Charles C. Adams, Chairman; Study of Game Mammals, Charles Sheldon, Chairman; Anatomy and Phylogeny, W. K. Gregory, Chair- man; and Bibliography, T. S. Palmer, Chairman. The policy of the Society will be to devote its attention to the study of mammals in a broad way, including life histories, habits, evolution, palaeonto- logy, relations to plants and animals, anatomy and other phases. The Society arranged to start the pub- lication this year of a "Journal of Mammalogy," in which popular as well as technical matter will be presented. This journal will fill a long felt want in the natural history world, for with all the pub- lications dealing with bird life on this hemisphere, there h?s been none making a specialty of the no less interesting and important mammalian life. In choosing the name of the Society, the word American is used in the broad sense of including all the Americas, North as well as South. Canada was represented at the organization meeting by two men, and several Canadians appear among the charter members. The Society starts out demo- cratically, with but one class of members, the gen- eral concensus of opinion being that the establish- ment of fellows and different classes of members would not be conducive to the good feeling and harmony desirable in a society of scientific aims. The Society invites the co-operation and support of all persons in the study and conservation of the mammalian life of America. Remarks Concerning Sand Launces. There has recently been received for identification by the Fisheries Branch of the Department of the Naval Service a number of small specimens of Sand Launce (Ammod^les personatus) obtained from Barclay and Clayoquot Sounds, British Columbia. The genus Ammo(i^)ies is represented on our coasts by three reported species m all, and all of which inhabit sandy shores. The geographical ranges of the three are as follows: A. personatus: Shores of the Pacific from Cali- fornia to Alaska, embracing British Columbia and the Aleutian Islands and westward to Japan. (This is the species of which the Department received specimens.) A. americanus : Maritime Provinces, Gaspe Basin, Labrador and Newfoundland, southward to Cap:; Hatteras, North Carolina. A. dubius: Labrador and Greenland, southward to Cape Cod. (As its name implies this is a doubtful species, and was first recorded by Rein- hardt in 1838.) Altogether there are about eight different species of sand launces, of which, besides our own, may be mentioned A. lanceolatus and A. tobianus, both of which occur on the British coasts. Andrew Halkett. THE mountain BLUE BIRD, AND ITS IRREGULAR APPEARANCE. Every observer of birds has noticed the abundance or scarcity of certain varieties in different years, and the reason of this periodical variation in appearance is often hard to account for. There are several birds that come under this class in Alberta, and perhaps the most prominent of these is the Blue Bird, (ours is the Mountain variety Sialia currucoides.) The winter of 1917-18 was quite severe up till about the middle of March, when it turned very mild and spring like. On the 21st of the month I was very much surprised to see three Blue Bird flying along the telephone wires on one of the prin- cipal streets of Camrose. This was fully two weeks earlier that I had ever recorded them before in my twenty-eight years residence in Alberta. A few days later the weather turned suddenly cold, and the month ended with below zero tem- peratures. The cold extended into Montana, be- tween 200 and 300 miles south of this latitude. There is reason to believe that these three birds were not the only ones to come north around the 21st of the month, and it is likely that a large mi- gration took place at that time. The cold weather 11 The Canadian Field-Naturali?t [Vol. XXXIII. came on so unexpectedly that there can be little doubt but what all the Blue Birds that ventured so far north at that time must have perished. The consequence was that there was practically an entire absence of these birds in this district the following summer. F. L. Farley, Camrose, Alberta. On the early life-history of the American LOBSTER (Homarm americanus). Were this tiny creature, just after it has emerged from the egg, to be enlarged to say ten inches in length and a regular ten-inch long lobster put along side of it, two forms, quite unlike in general appearance would be seen. The reason for this difference in general form is because whilst the mature lobster crawls about upon the bed of the sea, the little juvenal does nothing of the kind, but swims, or rather floats upon its back, through the water or near the surface of the water. It would be interesting to follow out in detail how this most valuable of all crustaceans becomes more and more modified as it passes from moult to moult, but it must suffice for the present to point out that by the time the lobster has acquired the crawling mode of locomotion it has not then reached an inch in length. Obviously the free swimming mode of movement is primitive, and there are crustaceans, for instance the phyllopods, which swim upon their backs throughout their life-histories, but in the case of the decapods, which stand higher in the scale of crustacean life, and to which shrimps, crabs, and the lobster belong, this phenomenon is usually only temporary, and in the case of the lobster is purely so. Now when the mother lobster, guided by her instincts, approaches the more shallow parts of the sea in order that her eggs may hatch off her swim- merets, and once the eggs are all hatched off, her maternal duties are over, for that is all the maternity she has. The young nauplii are now left to their own resources. It was a wise provision of nature that led the mother lobster to the shallows, for the little helpless creatures are there defended against many dangers which would have been encountered further out at sea. Furthermore, they undoubtedly meet there with a plenteous supply of surface food. Nor is this all. In the sheltered harbors and bays the little lobsters have an opportunity to undergo their metamorphosis until as little crawling creatures they seek refuge among the sea-weeds and under the rocks; from which time on they become better and better equipped, through increase in size, a shell hardened with carbonate of lime, and a pair of powerful claws, to protect themselves at consider- able depths in more exposed parts of the bed of the sea.

Waugh, Geological Survey, Ottawa. Canoeing, it may be remarked by way of in- troduction, is one of a number of thmgs which have been borrowed, either for use or amusement, from the American Indian. The name, strangely enough, has been introduced from a region at some distance from that with which we are accustomed to con- nect canoe culture in its typical form, being derived from the word "canoa," in use among the Arawak of the West Indies. This was adopted in a similar form by the Spaniards, and as "candt" by the early French in Canada. The fact that there was already a name in current use, then, is no doubt the reason none of the names applied by the Indians of the Eastern Woodland area of America was adopted. An Ojibwa term, fairly well-known from its em- ployment by Longfellow in "The Song of Hia- watha", is "cheemaun". A name applied to a very large craft is "nabikwan". A Mohawk appella- tion is "gahonwe'ia" ; rendered by the Onondaga, a related tribe, as "gaho'nwa". It is interesting to note, in the last-mentioned dialects, the close resem- blance to the term for a bark bowl or trough. Quaint early English forms, now obsolete, are canow and cannoe . There is little doubt that, in the earlier days of French exploration and settlement along the St. Lawrence and of English settlement in New Eng- land, the birch-bark canoe of Indian make was very soon adopted as the most convenient method of travel. We can readily infer, also, from early writers and other such sources, the extremely im- portant part played by the canoe in the develop- ment of a very large portion of the North Am- erican continent. It would obviously be most interesting to trace the canoe and other such devices to their origins, but there are indications that the problem in hand is one of the diffusion or spread of a cultural trait already elaborated, or partly elaborated, it may be in some other region. This is in part suggested by both the extent and the continuity of the area in which canoes are used. We can see that migra- tions of population, or the influence of one tribe upon a neighboring one (accultural influence) would soon disseminate the canoe idea, possibly in a simple form, very widely, and that, under the influence of the varied materials at hand and diversified require- ments, specialization in various directions would later arise. Materials naturally played an important part.. In areas where trees were not at hand, or were less convenient, such materials as rushes were sometimes built into a boat-shaped raft (see the balsa of Cali- fornia) ; or a skin-covered craft was employed, as in the Eskimo area, among the neighboring Kutchin of the Yukon, the Tahltan and other Athabascans of the Mackenzie region, and in some parts of the Plams) see the "bull-boat," a tub-shaped craft of skin and withes, used by various Siouan tribes, in- cluding the Mandan and the Hidatsa; also by the Ankara, a Caddoan tribe). The Omaha (Siouan) used hide-covered boats or canoes of ordinary type, but with a rude framework, indicating the slight de- velopment among them of ideas regarding naviga- tion. In the last-mentioned craft, an oar or large paddle was used for steering, the paddlers sitting near the bow. One of the most interesting developments in North American navigation was the canoe of birch-bark, which apparently reached its perfection in the Algonkian area, a region extending from around the Great Lakes, and some distance west- ward, to the maritime provinces and the New Eng- land states, though the birch canoe area exhibits cul- tural extensions in various directions, but particularly northward and westward to the Mackenzie river basin. There is little doubt that this distribution was largely determined by the range of the canoe birch (Betula pap^rijera), which extends practically from the Atlantic coast to the Rockies, as well as to some distance south of the international boundary. The disappearance of the birch southward is indicated by the fact that very inferior canoes of elm, buttonwood and basswood bark were constructed by the Iro- quois of Central New York state and southward, who evidently found the materials Icist mentioned 24 The Canadian Field-Naturalist [Vol. XXXIII. more plentiful. The Iroquois canoe is everywhere stated to have been heavy and loggy, inconvenient for portaging and short-lived generally. In fact, so poor a craft it was in comparison with that of the Algonkians, that the Iroquois are said to have traded eagerly for the lighter and more substantial con- trivance.^ Bark and skin-covered canoes, however, are not the only craft which have been used by Canadian Indians, since at least two other devices usually constructed in a very primitive style are found side by side with considerable advancement in naviga- tion. The dugout, for instance, which is usually little more than a hollowed-out log, is employed by a great many tribes along with canoes of a much superior kind. Another very primitive-ap- pearing contrivance, the raft, is distributed quite widely, though employed to a greater extent in some areas than in others. It may be unnecessary, or even impossible, for us to decide which of the foregoing came into use first, but we should certainly be quite near the mark in placing the raft first in degree of simplicity, with the simpler class of dugout next. THE BIRCH-BARK CANOE. Practically everywhere within the region of Al- gonkian influence proper the birch-bark canoe was essentially the same, such differences as occur con- cerning mostly the shape of bow and stern, which has evidently been derived almost exclusively from a single pattern, with local variations in the amount of curvature or recurvature and the method of deck- ing over at the ends, where such a device was em- ployed. The Malecite (western New Brunswick) and Ojibwa forms are very good examples of the extremes in outline in the Algonkian region. The Malecite canoe also exhibits the decking-over sheet at the ends, with side-flaps, in a well-developed form. As we proceed westward, this sheet decreases in size in the Algonquin canoe of northern Quebec and Ontario and becomes vestigial in a smaller form used by certain of the neighboring Ojibwa. The same purpose, that of preventing the inflow of water, is accomplished by the recurving ends of the Ojibwa type with which we are most familiar. Regarding the Algonkian tribes of central Labra- dor, Turner remarks that "a tribe of great dis- similarity between the Naskopies and the Little Whale River Indians (Eastern Cree) is that the iDr. E. Sapir, in "Time Perspective in Abor- iginal American Culture," Memoir 90, of the Geological Survey (Canada), p. 20, remarks: "Sim- ilarly, the clumsy elm-bark canoe of the Iroquois seems less adapted to its cultural environment than the various types of birch-bark canoe of their Algonkian neighbors. We may risk the guess that the Iroquois bark canoe is an imperfect cojiy in elm- bark, a characteristically Iroquois material, of the superior Algonkian types, and connect this further with the general consideration that the Iroquois were rather more inclined to be cross-country walkers than the neighboring Algonkian tribes, who were more adept river and sea folk." birch-bark canoe of the latter is much more turned up at each end, producing a craft well adapted to the swift currents of rivers." He also states that "the occupants are skilful boatmen," that "sails are sometimes erected in a single canoe," and that "at times two canoes are lashed together and a sail spread from a single mast."- An offshoot of the Algonkian canoe was the "rabiscaw" of the Hudson Bay Company, an extra large birch-bark craft designed to meet the demands of the fur-trade. A prominent feature was the high, upturned bow and stern decorated with gaudy designs. At the western extremity of the bark canoe arc" we find at least two somewhat divergent forms which suggest an attenuation of eastern accultural influence, combined, possibly, with modifications from other sources. The Dog-ribs, an Athabascan tribe of the Mackenzie basin, like the Ojibwa, construct a birch- bark canoe having separate keel-pieces for the bow and stern. The small and narrow ribs and the slender, widely-separated siding or flooring strips extending from end to end, however, show some resemblance to kayak construction. A special fea- ture (also showing a resemblance to the kayak)'' is the fairly extensive sheet of decking at either end. Conspicuous side-flaps, of the type found in the Algonquin decking, are lacking. The seams are sewn with spruce root and gummed. Among the Kootenay and the various Salish tribes of southern British Columbia is found a canoe of pine or spruce bark, rather rude in general work- manship and showing but little external resemblance to eastern forms. The most striking feature is the peculiar pointed extension of the lower part of bow and stern, which is said to be specially adapted to rapid rivers. From a structural point of view no radical difference from eastern types is to be noted. The bark of the yellow cedar (Thuja excelsa) is also mentioned as a British Columbia canoe-making material. A Slave canoe from the neighborhood of Hay river (flowing into Great Slave Lake) exhibits an upward extension at the bow and stern which adds much to its picturesqueness. In other respects it conforms closely to eastern models. A description of Ojibwa canoe-making will no doubt give a fair idea of the methods employed throughout most of the bark canoe area.^ The process is most interesting and requires considerable skill. sTurner, Lucien M., "Ethnology of the Ungava District." llth Annual Kept, of the Bureau of Eth., Washington, D.C., p. 182. sMention of this resemblance is made by Pet- itot, m "Autour du Grand Lac des Esclaves," p. 268. 4<^rom data obtained by the writer among the Saulteaux, or Ojibwa of the Lake Nipigon region.

Thin strips of cedar (Thuja occ'idenlal'is) for the ribs, and the sheeting used between the ribs and bark to prevent injury to the latter, are obtained, split into approximate sizes and placed in water to render them more flexible. Another important requisite is the birch-bark, which peels off most easily late in June or early in July. This is rolled up and laid away in the shade. Towards evening, or at any time, if the day is cloudy, stakes (nine or more to a side) are driven into the ground at intervals to approximate the length and width of the canoe. These are made to flare outward slightly. The bottom pieces of bark are now placed in position, overlapping a few inches in the middle where they are to be joined. A single length of bark is pre- ferred for the bottom. This, however, is not always obtainable, so that two pieces, or even three, may be used. Stones are laid on the bark to hold it down, and a bottom frame, approximating the width of the canoe at the bottom and pointed at both ends, is applied. The work so far is done by the men. The next operation, that of shaping the bottom by making slashes or gores on each side and sewing these with spruce root, is done by the women. The gores are made towards the ends, where the canoe begins to narrow. The upper edges of the bark are also trimmed evenly. The spruce root for sewing has been split by the women to a suitable size and rendered flexible by steeping in fish broth. The men next lay the upper lengths of bark along- side, measure them by trial, then place them in position. The bottom pieces are now scored along the bottom with an axe where they are to be creased for the taper to bow and stern, after which both upper and lower barks are pinched together by stakes driven closely and tied at the top. An inner frame (or "inside gunwale") giving shape to the upper edge of the canoe, and having exactly the right taper and curve, has been prepared be- forehand and is now placed between the upper barks and sewn closely and firmly to them. Pieces of cedar, bent to the approved shape of bow and stern, are placed between the barks at the ends of the canoe, the bark trimmed to conform to these in out- line, then sewn to them with spruce root. The Sevang, as before, is performed by the women, to whom this part of the work is always assigned. Stitches of uneven length are often employed, par- ticularly around the ends, to prevent the bark from splitting.'^ The gores and laps have in each case been well cemented or stuck together with clear gum boiled a little to thicken it. r.Other devices for preventing the edges from splitting along seams, are: The sewing of an extra strip of bark around the outer edge of the canoe beneath the gunwale; also the inclusion under the stitches of a strand of spruce root (often used along longitudinal seams where barks are joined). Both of these schemes are employed by the Dog-ribs Slaves and Chipewyans. The bottom frame, which is merely temporary, is now removed, the ribs taken from the water, bent to shape around the knee, cut to length and driven into place with a mallet. Other thin strips of cedar, three or four inches wide, are driven between the ribs and bark as the work proceeds. The purpose of these is to form a protective flooring and siding. The canoe, particularly at this stage, is kept well moistened both inside and out. The placing of the ribs and sheeting proceeds, generally speaking, from each end to the centre. Cross-pieces, to keep the top spread, are hammered in at every second rib. The ribs are a couple of inches wide and about ihe some width apart. When the insertion of ribs and sheeting is completed, the canoe may require a gen- eral correction in shape, which is given by tying it between stakes and exposing it for a while to the sun. The next process, also a woman's job, is to get ready, or rather, to have ready, the spruce gum and to gum the seams. All laps have their outer edges running backwards or towards the stern, so as not to obstruct the motion of the canoe. The spruce gum IS obtained from trees which have been gashed the year before, is boiled a while to thicken it and mixed with powdered charcoal some say, to make it look nice. The bottom seam is coated with clear gum and pegged, not sewn. A little grease is said to be added to the gum by most tribes to render it more elastic. The ad- dition of the powdered charcoal is not universal. Among the Micmac of Nova Scotia and Cape Breton the women and girls are said to have pre- pared the gum by chewing it. The last step in Saulteaux canoe-making is to attach a top gunwale strip. This is nailed on at present, but may have formerly been fastened on by tying or binding with spruce root. The Malecite, according to information supplied by Mr. William Mclnnes, Director of the Geological Survey, Ottawa, construct temporary or emergency canoes of spruce bark which are used for bringing out furs from the hunting camps in the spring. The ribs and frame are roughly constructed of withes or saplings, flattened slightly and rather widely spaced, the bow and stern being chinked with clay. Mr. Mclnnes also furnishes an interesting de- scription of the manner in which the Malecite protect the bottoms of birch-bark canoes in shallow streams: Lengths of spruce bark, with the smooth inner sur- face placed outward, are wrapped around the bot- toms of the canoes from end to end and held in position by tying their edges to the thwarts with cedar inner bark. Another material, which is pre- ferred to the spruce bark on account of its lightness, consists of strips of cedar about two inches wide and three-quarters of an inch thick. The strips run May. 1919] Plate II. /. 3. f^it^- -'1 J I '' II "_' in'L^ - i V V]-,-!] ,JT Illllllll1ll |)l |!)l|l |lll\llllllll| f!l^ i)\ CANADIAN CANOES. 1, Ojibwa canoe (Northern Ontario): 2, Chipewyan: 3, Slave; 4, Kootenay, Shuswap and other southern B.C., tribes; .5, Haida.

The sides of the Micmac canoe are up-curved and turned in towards the centre to exclude heavy seas. The Eskimo kayak, for present purposes, may be regarded as a highly specialized canoe, differing from the Algonkian in the important, though not essential, respect of having the framework so con- structed that it is held together independently of the cover; and in the superficial one that the covering ^ ^ / V /. 2. 3. ^ .' 6. 7. 8. fl.

ESKIMO CANOES. In only one region, the great insular area of the North Pacific Coast, was a true seafaring culture is of skin instead of bark, to which we may add that of being decked over so as to accommodate, in most cases, but one person. The upper rim or frame of two pieces is made first, with mortises for the insertion of ribs and thwarts and holes for lashings. The thwarts are placed in pos- ition and the upper part or deck practically com- pleted, one of the last steps being the attachment of a middle strip lengthwise along the top, except where it is intersected by the opening or man-hole. The whole affair is then turned top or face down- May, 1919] The Canadian Field-Naturalist 29 wards. The ribs are now shaped and fitted and their ends inserted in the upper side-pieces and secured with wooden pins. The ribs are usually from two to six inches apart. The other longitudinal strips are then attached to the sides, with a similar piece along the middle of the bottom, which, like the other canoes described, is destitute of a keel. The sealskin covering is sewn together and ap- plied to the framework wet, so that it stretches tightly as it dries. The sewing, as in the case of the Algonkian canoe, is done by several women working together in order to complete the job at one sitting. A double waterproof stitching renders the seams water-tight. of Yukon Territory and Alaska possesses features which give it an intermediate position between the umiak and the canoe of the region to the south and east. A canoe-like feature is the wedge-shaped bow and stern. A pointed or leaf-shaped paddle is used. The umiak is said to have been entirely aban- doned on the east coast of Labrador." In parts cf the latter region and in Alaska it is used largely by the men for whale and walrus hunting as well as for general purposes. Lengthy journeys or migra- tions are often undertaken in it and its capacity is said to be remarkable. The bow and stern of the Labrador umiak are DISTRIBUTION MAP, the dotted portion showing the Eskimo kayak and umiak region, and tlie part covered by oblique lines, tlie bircli-bark canoe region. According to E. W. Hawkes, from whose memoir wider than those of the Alaskan, which gives it a on the Labrador Eskimo the foregoing description is clumsier appearance. It is usually about twenty- taken, "Great speed is maintained by the Eskimo in five feet long and is steered with a rudder, quite their frail kayaks. It is said that a single Eskimo likely an Asiatic borrowing, as are also the oars. in a kayak will propel it as fast as two white men will a canoe. The Eskimo ventures out in a sea that an Indian would not dare attempt. . . .''" The umiak, an open craft, also used by the Eskimo, presents a somewhat different appearance from the kayak due partly to its not being decked over and partly to its being rather deeper and rowlocks and sails. In Alaska the umiak is pro- pelled by the more aboriginal paddle, the steering being done with an extra long and heavy one. SAILS.
