24 THE SCIENCE OF DRY FLY FISHING. 



In Diagram 5 the spectator is supposed to be vertically 

 above and looking down at the fisherman at B, and in 

 Diagram 6 the spectator is supposed to be on the ground, 

 but slightly above the top of the rod. The fisherman lifts 

 his fly from C by the back stroke of his rod from A to R, 

 which stroke is made vertically in the ordinary manner, 

 but at the precise moment in which his back switch stops 

 his body should swing steadily round from the hips so as 

 to face D, the desired direction of his proposed cast. The 

 arm, wrist, and hand should be, as I have formerly pointed 

 out, quite rigid at the end of the back cast. This rigidity, 

 combined with the swing of the body, will cause the point 

 of the rod to make a horizontal curve to the left behind 

 the fisherman (see Diagrams 5 and 6), the point of the rod 

 tracing a curve from R along r, r, r, r, to E. 



The line, as it travels back towards K, will curve in 

 sympathy with this movement of the point of the rod, and, 

 leaving the plane of the back cast R K, it will curve in a 

 lateral direction (see rb, rb, rb, rb) towards the new plane E F, 

 the line having attained the curve E b by the time the body 

 has swung round facing D. The influence of the wind will 

 always affect this curve. 



The forward vertical switch should now be made as 

 usual towards D, and the line will follow the vertical 

 plane E F (see Diagrams 5 and 6), and the fly will alight 

 in the required direction D. 



In this movement of the body the balls of the feet
