TROUT INSECTS FOR MAY 



to which were most valuable in each class. I think 

 it is desirable to cut down still further the number 

 pictured on the May page to, say, eight specimens, 

 viz.: two drakes, two duns, two browns, one spin- 

 ner, and a two-winged fly, the cowdung preferred. 



Each monthly page contains an average of 

 twenty flies, and for the season makes a round hun- 

 dred. I don't suppose any angler would want such 

 a large variety, because it is always well to have 

 more than one specimen of each fly in stock. It is 

 for that reason I shall give a selection from each 

 colored page of those flies mose needed, and best 

 worthy to use. 



It is impossible to tell in advance what natural 

 insects are on the wing, because their flight depends 

 so much on weather conditions; but I can, with 

 some degree of certainty, tell the right times to use 

 each of the different flies. And this information is 

 given, as far as it is possible to do so, in the charts 

 that accompany the colored pages.
