CHAPTER II 



CORIX.E l 



WHILE fishing in a water where the trout 

 are very numerous in the spring of 1897, 

 I found that I could hardly catch a single 

 trout in the day with the fly. The weather 

 was cold and windy, and showed no signs 

 of mending. At last, one day, I opened a 

 trout, one of the few that I had caught 

 during my visit, and found the stomach 

 full of some insects belonging to the family 

 of Corixse. These insects are very com- 

 monly called Water Beetles, or Water Boat- 

 men. They, however, are not beetles but 

 bugs (Heteroptera), and are not the same 

 as the true water-boatmen, the Notonecta 

 glauca, though they somewhat resemble it 

 in appearance.
