THE CADDIS OR STRAW-BAIT. 203 



the gentle streams and pools of trout and grayling 

 rivers as the cad or straw-bait. These baits are 

 the larvae of several of the angler's best flies. 

 Captain Williamson says : ' In applying this bait, 

 the point of the hook should enter close under the 

 head, and be brought out at its other end, if two 

 are used. When a very small hook is used, one 

 caddis may answer, and then the hook must not 

 be brought out at its end, but the point must rest 

 just inside the end of the bait. In general two 

 will be found best ; it being indispensably neces- 

 sary to cover every part of the hook. In the latter 

 case the first caddis should be carried round, so 

 as to conceal all the shank, while the other fills 

 the bend and conceals the point. Caddies are 

 in season only during the summer months ; they 

 generally make their first appearance in May, 

 and by the end of June are most numerous.' Mr, 

 Elaine, after examining several authorities re- 

 specting the merits or demerits of this bait, says : 

 6 We may sum up these contradictory accounts, 

 by adding the result of our own experience, which 

 is, that in some small rivers with little run they 

 will kill every kind of worm -taking fish at bottom. 

 In large, rapid streams, particularly such as run 

 over limestone, they are but indifferent substitutes 

 for gentles or worms.' 



An artificial caddis, very attractive on warm 

 windy days, may be very easily made. Wings,
