ON RAPID STREAMS. 187 



contrary, more fish may be taken with the worm, 

 when the river is moderately full than when very 

 low, cceteris paribus, and this must be so from the 

 very character of its usage. It kills so power- 

 fully by picking out the trout from those nume- 

 rous little spots they select to feed in apart from 

 larger currents and pools, but the number of these 

 little feeding spots decrease in the same ratio as 

 the water subsides. There are then much fewer 

 fishing spots in low water' than in full stream 

 the field for labour decreases, and with it its 

 rewards. Indeed, this argument will apply pretty 

 generally to all the modes of fishing I am a3- 

 quainted with, and it is obvious enough to require 

 no further comment.
