40 OLD FLIES IN NEW DRESSES 



Another, and perhaps a better, way to 

 observe the appearance of the fly from 

 below the surface is to put it on the water 

 in a large glass aquarium. It can then be 

 observed by looking up at it through one 

 of the sides of the aquarium. 



It is better to use tinsel in dressing 

 these flies than wire, as wire does not re- 

 produce the metallic effect of the air 

 bubble on the body of the natural fly.
