TROUT FLY-MAKIKG. 63 



trout and grayling flies, dressed on eyed hooks, ever ap- 

 plied to that purpose ; while, at the same time, owing to 

 the hook's eye having only to be large enough to pass the 

 gut once through it, it is also the smallest and neatest. 



Figure 23 shows the knot and its method of tying, in 

 accordance with the following explanation : First take 

 the fly by the head with the eye turned upwards, Pass

 round the center link, d. 



Second draw the slip knot tight enough only to ad- 

 mit of its just passing freely over the hook's eye (a, fig.

 en gradually pulling the central link tight the "jam" 

 knot is automatically formed, as shown in figure 24, which 

 shows the fly, actual size. Finally, cut off the superfluous 

 gut end to within from rather more than one-sixteenth 

 to one-eighth of an inch, according to size of the hook. 

 For salmon flies an additionally secure knot if such 

 be possible has been tested. It is shown in Figure 25, 

 and is termed the " double-jam" knot. The method of 

 tying it is as follows : Take the hook by the bend be- 

 tween the finger and thumb of the left hand, and with the 

 eye turned downward, in the position shown in the dia-
