116 THE SCIENTIFIC ANGLER. 



seen fluttering in clouds in the shade of trees, bridges, 

 etc. They are of a dingy brown shade on the body, legs, 

 and wings, and unless seen in a certain light are almost 

 indistinguishable when in action over the water. There 

 are two sizes of these flies when full grown, the largest 

 being fully half an inch in length, the other about two- 

 thirds that size. This is one of the best of our grayling 

 flies. The fish being partial to small insects, the lesser 

 one is generally used by most fishermen. This fly fre- 

 quents some streams in lieu of the Willow, and is equally 

 killing. Needle flies are numerous on warm mizzly days, 

 throughout the fall of the year. 



The Yellow Sally concludes the list of the Perlidce 

 order deserving the notice of the angler. The fly is of a 

 general primrose tint, and when once seen can never be 

 mistaken. It rises about the middle of June, being more 

 or less numerous during the hot months, but is not 

 much appreciated by the fish. It is seldom really on the 

 water, even when well out, being a stray flier, often 

 descending from a great height to deposit eggs in the 

 water, falling apparently lifeless, but immediately spring- 

 ing up to soar anew, and repeat the operation. The 

 artificials of this fly fail to be effective, owing to their 

 being dressed "winged;" most flat-winged water flies 

 should be dressed "buzz"* to kill well. The best 

 chance of killing with this fly is during or soon after a 

 passing storm, which beats them down upon the water. 



We have now enumerated the three principal orders of 

 winged water insects. A reproduction of one of each 

 some accomplished fly-fishers place upon their casts for 

 all round fishing; but we do not advise our readers to act 

 up to any system, but would rather encourage them to 

 use their own observation, to be quick to take note of
