TROUT RISING FOR SPORT. 117 



the droughts of summer, when the waters .are fine, 

 and all kind of insect food cry " Eise and eat" (like the 

 porkers of St. Salvador, which are said to perambulate 

 the streets with knives and forks ready stuck in their 

 backs), small flies will generally do more execution than 

 large ones. But in rough streamy rivers, where there 

 is only a moderate supply of insect delicacies, the fish 

 evidently prefer more substantial fare, as here it is a 

 dinner and not a dessert they are in quest of ; and the 

 representatives of the larger flies, of the full natural 

 size, will be most in request. In such waters, a large 

 trout will not be at the trouble to put his ponderous 

 carcase in motion to capture a nonentity.
