FISH: THEIR HABITS AND HAUNTS. 51 



detect with a glance of the eye the places 

 where salmon may with most probability be 

 expected to lie. It is not often that he is to 

 be found in long, straggling streams compara- 

 tively shallow, and not leading directly into 

 a longer or shorter reach of deep, still water. 

 He is always very shy of trusting himself in 

 such places. On the contrary, a rapid 

 stream, running directly into a sheet of deep 

 and still water, is his most probable haunts. 

 Many large fish, however, never go into the 

 stream at all ; they keep in deep water 

 among large stones, brushwood, and old 

 sunken roots of trees. When, therefore, 

 there is a fine brisk curl on the surface of 

 the water, and it is otherwise in good con- 

 dition, the deeps are the place for finding 

 fish. The shallow end or tail of a good long 

 deep, where there is a broad bed of grander 

 slopes, is in all salmon rivers a favorite spot 

 for fly-fishers.
