AMERICAN TROUT-STREAM INSECTS 



a selection of the artificials. By a fair test — I care 

 not what water it be, if within the temperate zone 

 — I mean that the angler can choose any one single 

 fly and cast it where trout lie, at the right time men- 

 tioned in the fly chart, and my firm belief is that, 

 if played as directed, it will attract and hook more 

 trout, as weU as give more universal satisfaction, 

 than any six varieties of fancy flies cast in a "chuck 

 and chance it" style. It must be so, unless trout 

 get tired of their own natural food to prefer some- 

 thing different, which seems to me improbable. My 

 sole aim is cunningly to deceive the trout: that is, 

 to induce the fish to imagine it is really taking its 

 natural food, in the form of an artificial true in 

 color, shape, and size. 



Concerning tests being made of these new flies 

 in more northern waters — that is, in Maine, New 

 Brunswick and western Canada, including also the 

 Northern Pacific States — I shall look forward to 

 such tests with deep interest. I shall make the 

 tests myself at the earliest date, at the same time 

 making a collection of sketches of the insects native 

 to those regions. The difference of temperature 

 will, I think, have little effect on aquatic insects of 

 the two zones, especially about midsummer. The 

 difference will be greater early and late in the sea- 

 son.
