TACTICS 115 



The angler, knowing the cause, should watch 

 for these effects, as he proceeds up the pool or arrives 

 at a new one. If he observes an air-bell floating 

 within the shelter of the bank, he should send out 

 his fly to investigate whether it has been left there 

 by a feeding trout. Frequently such a sign has 

 invited us to switch a fly across, and often the 

 raising of a fish has proved to our satisfaction 

 at least that our deductions had been correct. 



Though it is a rule that a dry-fly must be cast 

 up, or up and across stream, there are notable 

 exceptions. Of these we have already pointed 

 out one, but there is another. Sometimes a trout 

 will take up its feeding station in an awkward, 

 curving corner, or so near a piece of rough water 

 that an upstream cast is foredoomed to failure. 

 A dry-fly can be floated down to a trout by means 

 of a downstream cast, and a very interesting 

 cast it is to execute, highly successful too, if there 

 is sufficient depth of water to afford the angler 

 concealment. Naturally it is of limited applica- 

 tion, but nevertheless many a trout has succumbed 

 to these tactics. 



Thus it is that dry-fly fishing can never become 

 dull. Its practice induces, encourages and repays 

 study of all the moods, peculiarities, and surround- 

 ings of trout. Every day brings its own problems, 

 and in their solution the angler finds much of his 

 happiness.
