The timber about Big Fork is chiefly yellow pine, Douglas 
balsam cottonwood mong the smaller trees and shrubs were 
dwarf maple, black haw, alder, red cedar, low juniper and 
species of willow and wild rose. The wild syringa was in full 
loom on our arrival, the large waxy-white flowers borne in 
clusters in great profusion vieing with a species of Holodiscus and a 
Spiraea in being the most conspicuous object in the woods. e 
latter, having large, plume-like panicles of small, white flowers 
ing to cream-color then yellowish-brown, forms large, graceful 
shrubs several feet tall, usually occurring in clumps. The nine- 
bark, service-berry, silver-berry, choke-cherry, thimble-berry, 
prickly currant and gooseberry were common. The latter, which 
was found with fruit nearly black, or sometimes wine-colored an 
in some cases a clear golden-yellow-brown, was mildly sour and 
een good to eat. They may possibly prove to be different 
spec 
The bucethonn from which Cascara Sagrada is made, was n 
common but occasional here and also at Ravalli. The aie 
trumpet honeysuckle was one of the attractive features of the 
deep woods. Mountain alder was found with white cedar, silver 
pine or white pine, Lodgepole pine and dwarf yew a few miles 
east of Big Fork along the Swan River. 
The highest elevation at which we collected was on Mt. Mac- 
Dougal (7,500 feet), which we visited on July 31. This gave us 
a range of 4,500 feet in elevation from the lake level. The way 
lay mostly through heavy timber with occasionally a small lake 
orswamp. The silver pine became more abundant as we neared 
the mountains and Lodgepole pine, western larch and balsam 
cottonwood were found extending far up the slopes. Our trail 
up the mountain pe was through a “burn” thickly overgrown 
with Jersey tea. Three species of huckleberries, which were 
delightfully area were abundant, the two large, purple- 
fruited ones and the low red, small-fruited nes pe or 
Alpine fir, Englemann’s spruce, Alpine pine and Alpine juniper 
were found on the highest elevations.
