From tributary to Coppermine river (below Bloody Fall). F. Johansen.) February 10, 1915. (Photo by "Pihumalerksiak island, Dolphin and Union Strait, [off Cockburn point—]. The vegetation of this island is rather scarce and stunted owing to its exposed position and poor soil (dolomite-rock or gravel); it is best developed in depressions, or in shelter of protruding chff-parties or large boulders. The conditions and the vegetation are thus similar to those found on the island (except Chantry island) in the outer harbour at Bernard harbour, "The willows in question grew in patches here and there; generally several plants together; growth prostrate, and each plant not nearly as spreading as on the mainland. "Bernard harbour (mainland), Dolphin and Union strait. Very common everywhere, especially on poorer soil (sand, gravel), where it is one of the domin- ating plants. On such gravelly and sandy soil with little other vegetation and where more exposed the plant spreads out over the ground (not half buried in the sand as is the case with S. ovalifolia) in all directions, the whole plant remind- ing one of a huge basket-starfish. The centre of the plant is elevated most (thick trunk-bases, many dead leaves); and most of the leaves and catkins are found at the terminal branch-ends, which seem to seek out small depressions in the ground to shelter the twigs. The diameter of a very large plant may reach a couple of yards; its height over the ground only a few inches. As is the case with other prostrate willows the female catkins are less likely to be blown off the plants during the winter, where these latter (not the catkins) are snow- covered. In 1916 the season was several weeks earlier than in 1915, and the catkin-buds were noticed to emerge from their bracts in the end of May, 1916; thou
