In company with a party of botanists and others, the wirter spent the summer of 1905 in the Selkirk Mountains of British Columbia, much of the time in scientifically unexplored parts of that beautiful range. The Selkirks occupy the major part of teh Kootenay district of south-eastern British Columbia. It will be seen by reference to a map that they are bounded on practically all sides by the Columbia and Kootenay Rivers and the long and narrow Kootenay Lake.
