in large numbers. Most of the trout I saw taken from it in 
1900 were rather lean, though otherwise in good and healthy 
condition, and suggested that possibly it was becoming over-

Of the 27 stomachs obtained, one was empty, and the con- 
tents of another were lost through the breaking of a bottle, 
leaving 25 for study. I give below in tabular form a bare state- 
ment of what these 25 had eaten, and follow it with an account 
of what has been learned elsewhere of the biology of the insects 
constituting their food.
