They had evidently by instinct foreseen this before hand, and sure eaough, a heavy rain, enough to flotit a boat over the spawning bed came a few jj days after the parent fish had died. In the last struggle of life, both fish had run under \ an underhanging bank, and later both bodies. THE FISHING FLEET ^Iwere partly covered with sand and coarse 3 gravel from the recent flood effect of the |stream. The one nest that was under my linvestigation had about 800 eggs therein, ^iind I would say one half were dead on the 10th day, as up to this time I had not dis- turbed them. Before they had reached the "'eyed" stage 200 more were dead, caused probably by nonffertilizaton. 1 say they died because of non-fertilization because there was no fungas growth at that depth of gravel, even on spawning streams that are crowded with fish. I have noticed that the male is kept so very busy fighting off trout or other enemies, preventing them from eating the eggs, that he is not always on the spot to fertilize the eggs, and hundreds are washed w.
