body from right to left. 



Observe (i) tliat if tlie thrash-down is started hiter, the curved 

 part of the hne may possibly range astern as far as the fly is made to 

 circuit in the Underhand — at any rate, too far for the orderly achieve- 

 ment of the object m hand. (2) That the line should be brought 

 round witliin, or but very little outside, the track taken by the point 

 of the rod ; (j) That there is no pause whatever in the rod's 

 movement, which is one incessant and undivided motion, not varying 

 in pace until the moment comes for the thrash-down. And remember, 

 that even resolute adherence to these tactics may yet be rendered 

 futile by the intervention of the wind. 



The thrash-down, however, is practically a thrash-through, seeing 

 that the rod, as formerly stated, is not checked at the finish. 



In this tlirash-through, the centrifugal force (which emanates 

 from the generating centre of the butt, i.e., where the strength is 

 applied), continues its course along the rod, expelling the line, and 

 exhausts itself during the transit of the fly from water near the 

 fisherman to its destination. 



The second and more effectual way differs only in this : That, in 

 renewing a cast when the rod has been elevated as before, instead of 

 dragging the line along near the surface, it is made to take an 

 extremely sinuous course higher from the water (see dotted line. 

 Illustration 2). This is accomplished by a sliglitly varied vwvciiicut 

 of the rod at starting. In the former case, the line is first animated 

 by the rod moving against the current, outwards, downwards, and 

 away in a right hand direction. In the present case (see Illustration 

 i), the line is first set in motion by slightly raising the point of the rod 

 in journeying outicards, from which position, however, it diverges in
