was common around the shores of the lake, and in the woods might be 

 seen woodpeckers of several species. Cabanis's woodpecker was not 

 uncommon, Batchelder's woodpecker was occasionally seen and heard, 

 one pair of red-naped sapsuckers was seen for a day, the lordly pileated 

 woodpecker made announcement of his presence by his loud call and hard 

 and slow pounding on the trees, while the red-shafted flicker was seen 

 and heard daily. At dusk the western night hawk occasionally was seen 

 in the air, while during the day, strange as it may seem, an occasional 

 humming bird was seeking food from the various flowers about the lake. 

 The sharp and far-away sounding call of the western wood pewee was 

 frequently heard on the hillside. Wright's flycatcher was common iu the 

 timber south of the lake. The black-headed jay was not uncommon, and 

 a single curious Rocky Mountain jay was one day seen lurking around 

 camp. Higher up on the mountain, above 4,700 feet, Clarke's nutcracker 

 was found. In the woods adjacent to the lake the American crossbill 

 was common, and pine siskins were frequently noted in the air overhead 

 or occasionally were seen in camp having come for crumbs. Everywhere 

 on the reservation where observations were made the western chipping 

 sparrow was found. Around the lake Shufeldt's junco is abundant. Black- 

 headed grosbeaks were not seen about the lake, but at the ponds a mile to 

 the south they were abundant. The brilliant Louisiana tanager was every- 

 where to be seen, while the handsome cedar waxwing was frequently no- 

 ticed at the pond with the grosbeaks. The red-eyed vireo, warbling vireo, 

 Audubon's warbler, Townsend's warbler, and Macgillivray's warbler were 

 the insect feeders noted in the trees. The Rocky Mountain creeper was- 

 only occasionally seen, though the slender-billed nuthatch is common. 

 Every walk brought to view the long-tailed chickadee. The notes of the 

 olive-backed thrush were regular features of the woods. A single pair 

 of western robins were feeding the young on the nest during the stay at 

 the lake. 



The region seems to be a place of resort for birds, where they come 

 for a time and disappear, as is the case with the region as far as man la 

 concerned. Later investigations may reveal more. 



CONCHOLOGY OF SINYALEAMIN LAKE. 



One would expect to find an abundance of shells in and around such 

 a body of water as this lake. In this, as in many other points, there is 

 disappointment. These clear cold lakes do not offer a large supply of 

 food for such dainty feeders as shells and the supply is not abundant. 

 The small alpine form, Pyramidula strigosa, var. alpina, has been 

 previously referred to as having been found near the summit of the 

 mountain. In the woods along the borders of the lake the larger Pyra- 

 midula strigosa Gld., var. cooperi W. G. B., was taken rather abundantly. 

 With the preceding P. soiitaria was found in less abundance.. Only a 

 few Polygyra townsendiana Lea, var. ptychopliora A. D. Br., were taken. 

 These two have so far been found together, tue former most abundantly, 

 the latter much less so. These four land species were all that could be 

 found. In the water three more species were taken, all sparingly. 

 Physa heterostropha Say was not abundant, but several large and very 

 fine specimens were taken. Now and then Planorbis trivolis was seen.
