sional glimpse of the lake until the foot of the cliffs at the summit is 
reached. From this up the view is superb. 
The most impressive feature of the panorama spread before the eye 
is the great stretch of timbered country visible. Westward, to the 
summit of the Mission range there is nothing to be seen of the mountains, 
so well are they hidden by the forests of pine, fir, and tamarack. The 
lake with its swamp and meadow relieves the somewhat monotonous view 
of forest, and sparkles and glistens in comparison with the sombre green 
of the trees. It looks beautiful in the valley far below. To the south is 
the timber belt along the Swan river. Pathless save for the trail men- 
tioned, unbroken by the woodman’s ax save for the few trees cut by the 
early settlers along the lake shore, it stretches as far as the eye can 
reach, and dimly beyond may be seen the high snow crowned summits 
marking the valley yet almost unknown. On the right may be seen the 
high summits of the Mission range, McDonald being most conspicuous. 
To the left Swan peak rises high towards the clouds, and in late summer 
wears a crown of white. Eastward the lower summits hide the wooded 
valley of the South fork. Everywhere forests greet the eye. No one can 
comprehend the enormous quantities of marketable timber visible from 
the summit of this mountain, almost all of which is in the forest reserve. 
While the ascent is largely devoid of interest it is certainly worth 
while to see this great stretch of timbered country, and few are likely 
to make the ascent and be disappointed with the view. 
The ornithology of the lake has been partially studied by Mr. Sillo- 
way, who has a special report on the birds of the region. This will 
be issued separately later. Mr. Whitford has made a comprehensive 
study of the forest region about the lake. He has travelled through many 
miles of pathless woods guided by the compass. Several weeks have been 
spent in this work. The result will be of great value to students of the 
laboratory, and to students of forestry in general. His report will no 
doubt be published in full by the Bureau of Forestry. 
It would be premature to make report of the entomostraca in the 
lake. The material consists of collections made during two different 
summers. In 1900 the writer spent several days at the lake. Pumipings 
were made from different depths, and a number of surface hauls made. 
In 1902 Mr. Silloway made almost daily collections during the month of 
June. The work of Forbes has been previously referred to. 
Shell life in the lake seems to be scarce. No more than six species 
have been found in the water or along shore. They ure as follows: 
Planorbis trivolvis Say. At the lower end they seemed rather com- 
mon. At the upper end, in the swamp, Mr. Silloway secured a good 
series, and reported them abundant. 
Limnaea stgnalis, L. A few specimens of this large shell were pick- 
ed up at the lower end. At the upper end they were common in the 
swampy bay, where Mr. Silloway gathered a moderate quantity. 
Limnaea emarginata, Say. Specimens very cosely related to those 
found at McDonald lake, described as variety montana, were taken spar- 
ingly. 
Physa heterostropha, Say. A few were picked up along shore at the
