The trunks of young trees make excellent ridge-poles for tents. Myrica Gale L. Sweet Gale.â'Mouth of Chariot River, June 28; Hill Island Lake, July 15; Tsu Lake, August 9.

In the Tazin Highlands it reaches a fair size (40 feet or so) in favourable spots, but remains rather stunted in exposed, rocky places. By August 6, in the vicinity of Tsu Lake, the leaves on some of the trees were showing a tendency to turn yellow. By October 9, in the vicinity of Calling River, the birches had shed their leaves for the most part. I noticed birch-bark canoes on Lake Athabaska and on the lower Taltson River.
