2i8 THE DRY-FLY MAN'S HANDBOOK ^ 



insects in the air, sweep them from rushes, etc^ or 

 even held in the water to intercept any little insects 

 or larvae drifting down. 



The best material for all these nets is cheese cloth, 

 and for the miniature landing-net which is intended 

 to take floating flies off the water the two top joints 

 of an old pike-rod make the best handle. The dig- 

 ging-net should have a 

 strong iron frame about 

 inches long and 3J 

 \\ de of the form shown 

 >(l""ig. 33). The net at- 

 tached to this frame by- 

 string passed through 

 the holes should be a 

 long deep bag of cheese 

 cloth, and a strong ash 

 or bamboo staff four feet 

 long should carry it. 



For a rapid examina- 

 tion of the insects, and 

 in many cases even for 

 their identification, a 

 pocket lens is all that is 

 required. One of the modern aplanatic lenses made 

 by Zeiss, Reichert, Baker, etc., with a linear magnifi- 

 cation of ten diameters, and for examining mouth 

 organs, male appendages, and such matters requiring 

 a greater magnification,- similar lenses x 20 or x 30 

 can be procured from all opticians.
