the back cast as before. You are now ready to make the 

 forward cast. 



THE FORWARD CAST 



At the end of this backward motion of the rod it should, 

 being held firmly, remain stationary until the line has ex- 

 tended itself, and a pause is therefore necessary between

the backward and forward casts in order to allow this 

 extension of the line. It is the correct timing of this 

 pause which is one of the secrets of a successful forward 

 cast. This pause will vary in duration ; the wind, the 

 quality of rod, the length of line, and the force and speed 

 of the back cast, will all influence the velocity of the 

 backward-moving line.
