120 DRY-FLY FISHING 



usual distance, the fly will fall on smooth, slow 

 water and the line on a rapid current. The conse- 

 quence is that the fly, as soon as it alights, is torn 

 along the surface at the head of a fearful furrow, 

 and the trout flees in terror to the deepest depths 

 of the pool. 



If a good upstream wind is blowing, the angler 

 may wade forward it is generally possible in such 

 a place to do so allow his line, shortened to the 

 length of his rod, to stream out before him and dap 

 the fly just in front of the trout (see Chapter XIII). 

 If the wind is downstream or too light to permit 

 of dapping, he may move to 2 and make a hori- 

 zontal cast partly across country, or he may from 

 3 try the effect of floating a fly down to the fish 

 (see page 113). One of these methods is sure to be 

 better than either of the other two, and he must 

 decide, after an examination of the particular place 

 and consideration of the other conditions, e.g., 

 direction of wind, depth of water, which it is. Care 

 must be taken that as he moves to 2 or 3 he does 

 not betray his presence to the trout. 



The diagrams show a pool such as is described 

 on page no, viz. one having a brisk current flowing 

 down the centre ; but in this case the trout is rising 

 in quiet water outside the rapidly moving stream. 



If the angler casts as in Fig. I, the current will 

 act upon the line, carrying it downstream, and 

 sweeping the fly at great speed away from the point 

 where it fell ; Fig. 2 shows the probable position 

 of the line and fly after a second or two, and it will 

 be observed also that the trout has vanished. 



Let us suppose, however, that this fatal cast has 

 not been made. The angler has then several alterna-
