THROWING THE FLY.

A is supposed to be the hand, and A o A B 

 A i A H the rod in its various positions, c 

 M the river, c the spot whence the fly is raised 

 preparatory to the throw, and c G F E its course 

 backwards from the water, and E j K L M for- 

 wards towards it, M being the spot whereon it 

 finally alights. 



When the proper springs or jerks are given, 

 the hand follows the course of the line, but has 

 no controul so as to impede it after the springs 

 are given. Now let us understand the laws of 

 motion in the fly. Having, in order to neutralize 

 the effect of its inertia on the subsequent spring, 

 drawn it by a gentle motion from the interme- 

 diate space between M and c, the rod being 

 raised towards B, when the fly is at c and the 

 rod point at B (B c being the length of line to 

 be thrown) we communicate the spring ; leaving 

 the fly and line afterwards to pursue their own 

 course, and bringing the rod gently through the
