depend upon the tackle, which should be very nicely 
graduated, and if the cast is intended to be very extensive, 
one fiy only should be used ; indeed in salmon-fishing it is 
seldom that much good is derived from a dropper in ad- 
dition to the stretcher. When the fly is to be thrown 
in a wide river, of rather sluggish current, it may be 
directed nearly straight across, especially if the opposite 
bank can be reached ; and the fly, after it has touched the 
water, may be brought back with a circular sweep, keep- 
ing the rod low until it is absolutely necessary to raise it 
in order to bring home the fly, and working it by gentle 
fits and starts so as to imitate the movements of a living 
insect. When, however, there isa considerable stream, 
the fly may be thrown obliquely downwards, as in trout- 
fishing, and is then brought back against the stream, and 
often without that attempt at jerking which must be made 
in comparatively still water. In all cases, the salmon- 
fisher should keep as much as possible out of sight; and 
when he has recourse to wading, he should only enter the 
water which he has already effectually tried; and when 
there, he should make as little disturbance in it as he can 
possibly avoid. In this respect, however, salmon are 
duller and less wary than common trout, or even than sea- 
trout; but still they are easily scared, and no one should 
incautiously run risks which are not absolutely required. 
The fly is worked very differently to the trout-fly, which 
must always be on the top of the water to be effectual; 
whereas the salmon-fly should always be sufficiently under 
the water to avoid making any ripple as it is drawn towards 
the thrower, and yet not so deep as to be wholly out of
