quite destitute of trees. There are occasional small lakes, and here 

 and there marshes and small streams. "> 



On the drier slopes and ridges two species of juniper occur, Juni- 

 perus communis var. sibirica and Jumperus horizontaiis, both to be 

 seen in abundance from the river bank up to the Summit. Both species 

 grow as rather low, rounded bushes. On the higher mountain slopes 

 are groves of spruce and balsam fir, extending downward in cool, 

 shaded cafions, as along Telegraph Creek, or occurring so'metimes as 



Fig. C. East end of Sawmill Lake, near Telegraph Creek. Mammals that 

 especially frequent the grass and bushes about the shores of the lake are shrews 

 {Sorex personatus personatus and S. obseurus obscurus), Drummond meadow mouse, 

 and Stikine jumping mouse. Birds that nest amid the same surroundings are 

 the spotted sandpiper, alder flycatchef, rusty blackbird, rusty song sparrow, and 

 Forbush sparrow. The lesser yellowlegs was seen feeding about the shores of 

 the lake, but apparently was not nesting there. Grebes, loons, and ducks were 

 seen daily upon the lake during .Tune and probably were nesting. Photograph

small, isolated clumps on some north-facing slope well down in the 

 poplar forest. 



Of low-growing shrubbery, a conspicuous plant of the drier slopes 

 is Shephei'dia canadensis (locally known as soapberry), which forms 

 dense thickets of considerable extent. The berries are an important 

 bird food. The wild cherry {Prunus demissa) was another .noticeable 

 plant, forming dense thickets along the banks of the stream near the 

 town, the bushes from three to six feet high and, by the middle of 

 June, a mass of white flowfirs. The service berry {Amelanchier 

 florida) grows abundantly, forming bushes from four to ten feet high,
