TROUT FLY-FISHING IN AMERICA 



There is another element which now enters into the 

 consideration of this subject, namely, the distance from 

 the object that the real or effective background is located. 



The real background is always the sky-line; but the 

 effective background varies with conditions, the most 

 marked variation being when the fly is under the surface 

 of the water four or more inches ; and this is the only one 

 it is necessary for the angler to consider in relation to the 

 subject of what colored flies to use under different back- 

 ground conditions. 



When the fly is upon the surface of the water, or just 

 under the surface, not more than two to three inches, the 

 background can be taken as the sky-line above, and al- 

 though the background is made more or less effective by 

 conditions it is too nice a point for the angler to take into 

 consideration. 



When the fly is under the surface of the water four or 

 more inches the effective background may be either the 

 surface of the water or the sky-line above, depending al- 

 most entirely upon the coloration of the water and the 

 weather conditions. 



Let me say here in relation to this subject, that we will 

 consider black and white to be colors and that they rep- 

 resent the two extremes of fly and background coloration 

 and the degree of coloration diminishes as we leave the 

 black and approach the white, bearing in mind the while 

 that White reflects and Black absorbs both color and light. 



In fly coloration the White Miller represents White 

 and the Black Gnat represents Black. Place the White
