During the summer of 1915 I spent some time at the Biological Station of the University of North Dakota at Devils Lake, investigating the diatoms of the lake. Before this considerable diatom material had been sent to me by Dr. R. T. Young of the University, who is conducting the biological survey of the lake.
The immediate practical object in the survey is to determine the organisms in the lake in relation to the fish that might be able to subsist upon them, and diatoms being the most abundant of microscopic plants, deserve special attention in this connection. At present the stickleback, Eucalia inconstans, is the only species of fish in the lake, notwithstanding the fact that food is abundant. This species, however, is common.
