SPINNING WITH A SALMON REEL 367 



The trajectory of the lure after the drum is released from 

 control is shown in Diagram 23. This curve may be taken 

 as fairly representing the course of a lure when correctly 

 thrown from any make of a Nottingham reel. 



When the rod in its side swing reaches the angle at which 

 a free rotation of the drum is required, say at C 6, the drum 

 is permitted its freedom of revolution. Were the lure 

 entirely released from control, it would obey its centrifugal 

 impulse, and fly off at a tangent to the circle in which it had 

 been moving (see L 6 Q, Diagram 23) ; but it is not free, and 

 we have to consider the retarding influence of the line, 

 which not only prevents its taking such a tangential line 

 as L 6 Q, but which will affect and influence its direction 

 onwards. 



As the lure leaves its radial course and assumes a tangential 

 one, the line will begin to be frictionally affected by its 

 passage through the air, by the frictional resistance of the 

 rod rings, and by its having to overcome the inertia of the 

 drum. From these causes the direction of its tangential 

 flight will be altered, and its course will be curved 

 slightly inward and towards the place to which it is 

 destined. 



As the inertia of the reel is overcome, the other checking 

 influences increase in their effect, tending to check the passage 

 of the lure through the air and affecting the curvature of 

 its course, but this centripetal influence is thereon lessening 

 gradually, and making the trajectory flatter in character 

 as the lure travels onwards to its destination. 



The principal retarding factor is the line to which the 

 lure is attached. Owing to the free rotation of the drum of 

 the reel this line is lengthening rapidly, and owing to the 

 curving course of the lure, is being drawn sideways through 

 the air. To a small extent it is being moved forward at one 

 end by the rod top, and to a greater extent at the other by
