WHERE AND WHEN TO FISH 107 



The down-stream part of the imaginary semi- 

 circle will prove to be the least productive, for 

 the reason that it is difficult to interest a fish 

 from behind, he being more concerned about 

 happenings in front of him. Nevertheless, con- 

 siderable effort should be expended upon this 

 part of it, as there is always a possibility of the 

 fish being nearer the angler than has been cal- 

 culated. Having fished it thoroughly, the water 

 along the upper half of it may then be covered. 

 The edge of this segment of the semicircle should 

 be reached from a point nearly at right angles 

 to its tangent, the angler retiring and assuming 

 a position at a reasonable distance from the 

 point being assailed. The rise may be looked 

 for in that water where the swiftest part of 

 the current flows directly toward and against 

 the obstruction. And, as it is advantageous to 

 have the fly cover a great distance upon the 

 surface, it should be dropped a foot or two 

 farther up-stream from the snag than when cast- 

 ing to the side of it. If the flow against the 

 obstruction be studied there will be discovered 

 on the edge of the current nearest the angler a 

 spot whence the fly, being placed correctly, will 

 be carried down to the obstacle and around 

 it and will thus be exposed to the view of the
