62 THE SCIENCE OF DRY FLY FISHING. 



kindly courtesy of a French landowner in Normandy, taking a 

 day on his stream, in which he told me were many trout. 

 I had been doing well all the week, but on this day I had the 

 poorest luck, and, therefore, hastily concluded that the stream 

 was almost barren of trout. Consequently, on one memorable

 evening, that he had enjoyed a glorious day's trouting. I still 

 regret losing that excellent day, and consider that, as regards 

 any water, first impressions are not always the soundest. 



WATER INSECTS. 



The water insects whose flying appearance is copied 

 by the artificial fly makers are classified as follows : The 

 Ephemeridse, the Trichoptera, the Perlidae, the Sialidse and 

 the Diptera. In order that the student may be able to tell 

 to which of the above five families the flies he catches in his 

 butterfly-net belong, it will be advisable to remember the 

 following characteristic position of the wings of each family 

 when the fly is alive and at rest. 



THE EPHEMERID^E. The wings rise upward from the 

 shoulder in vertical planes above the body, generally 

 touching each other as they rise from the body. 



THE TRICHOPTERA AND THE SIALID.E (THE ALDER). The 

 wings run backward from the shoulder and lie alongside the
