 over the hook at a very horizontal inclination, 

 and the relation of each wing to its fellow 

 should be such that the effect produced is 

 that of a keelless racing-boat placed upside 

 down. 



Connoisseurs of Spey flies attach great im- 

 portance to the presence of the light grey roots 

 to the wings, as shown in Fig. 94, and in most 

 of the Spey flies in Plate VII. 



The wings should not extend beyond the 

 bend of the hook, and the head should be as 

 small as possible.
