Ww. RANDOLPH TAYLOR. 
In 1921 the writer made a camping trip through portions of the 
mountains of British Columbia with Dr. M. H. Jacobs, collecting 
algae and bryophytes as much as possible! During the past season 
under the same leader he was able to visit other portions of this terri- 
tory and to secure further collections. The party entered the Selkirk 
Mountains from Golden, B. C., in late August ard traversed succes- 
sively parts of Cañon Creek, the Spillamacheen River, Grizzly Creek 
and the Beaver River, passing between the first three by passes in 
which branches of these streams had their sources. Camps were 
made at various points on the North Fork of Canon Creek giving 
opportunity to visit several snow fields and small glaciers feeding 
this stream, and to visit that fork of Grizzly Creek which headed 
up with the North Fork. This is an entirely different Canon Creek 
from that visited in 1921 near Revelstoke. From a camp on the 
Spillamacheen a visit was paid to Prairie Mountain, which lies between 
the upper part of that stream and the Beaver River. This is a long 
grassy ridge, comparatively low, (6-7000 feet) with a few streams 
and springs which proved particularly rich. The party finally left 
this portion of the country at Connaught on the Canadian Pacific 
Railroad. A shcrt trip was also made up the Yoho Valley at Field 
and another in the neighborhood of Lake Louise in Alberta, but little 
collecting was done on these trips. Material was secured under much 
the same difficulties as on the previous trip and cared for in the same 
way. 
Instead of the rigorous weather conditions of 1921 the party in 1923 
was favored with clear skies and a warm sun, so that the pools in the
