130 THE SCIENCE OF DRY FLY FISHING. 



the finer and larger kinds, are superlatively good. Hardy 

 Brothers sell most excellent flies, not perhaps so small or 

 delicate as Messrs. Farlow or Bernard, but strong, useful and 

 attractive. I have some thousands of artificial flies, the 

 greater number of which are Farlow's, who have, by the way, 

 opened some new premises in Charles Street, St. James's 

 Square. 



BINOCULARS. 



There will be occasions when the use of the butterfly net 

 for securing floating or flying Ephemeridae may be impos- 

 sible or inadvisable. To give one such instance a trout 

 lying in a perfectly glassy backwater may often be observed 

 steadily rising and sucking down certain flies which are 

 floating down stream ; such a fish may be taken if an artificial 

 fly is delicately presented to him, but your chance of securing 

 him will be reduced to a minimum unless you present the 

 right fly at the first cast. 



It is essential to discover this fly, also to keep out of 

 sight ; below you the water is too deep for wading and 

 the flies beyond the reach of your butterfly net. 



The use of a strong and light pair of field glasses is 

 on this, as on other similar occasions, most useful. Concealed 

 below your fish in the long grass, with such a pair of 

 binoculars you can easily discover the sort of fly the trout 

 is taking, and also, any fly beyond the reach of your net.
