which will scoop them out admirably, allowing the water 

 to strain through the holes in its half cover. 



In some places, caddies are prodigiously numerous, 

 often covering the bottoms of the shallows, either in 

 pools, or at the edges of greater waters, and clinging to 

 growing or dead rushes, reeds, twigs, &rc. 



Although they may be used quite fresh, it is not, how- 

 ever, advisable to employ them until they may have 

 been kept about ten days, or even a fortnight, in an old 

 worsted stocking, or in a woollen bag, which should be 

 dipt daily, once or twice, into water. At the expiration 

 of such a period, the generality of the caddies will have 

 quitted their tubes, and have become tough, having 

 changed also to a rich yellow colour, in which state they 

 are a very alluring bait. If kept too long, they all turn 

 to various kinds of water-flies. 



In applying this bait, the point of the hook should 

 enter close under the head of the cadbate, and be brought 

 oat at its other end. When a very small hook is used, 

 one caddy may ans\ver - } but, in general, two will be 

 found best; it being indispensably necessary to cover 

 every part of the hook. In the latter case, the first caddy 

 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 make their first appearance in the month of May, 

 but by the end of June are in greatest abundance. 



This animal, which is the Eruca aquatica of naturalist s,, 

 afterwards goes through the regular changes of that tribe, 

 becoming a chrysalis, and ultimately taking wing. I am 

 induced to believe, that the ova require to be deposited
