the water ; and sometimes in an artificial fly, and late at 

 night or before sunrise in a morning, longer. 



Now both these flies, and I believe many others, though 

 I think not all, are certainly and demonstratively bred in 

 the very rivers where they are taken . our caddis or cod- 

 bait, which lie under stones in the bottom of the water, most 

 of them turning into those two flies, and being gathered in 

 the husk, or crust, near the time of their maturity, are very 

 easily known and distinguished, and are of all other the 

 most remarkable, both for their size, as being of all other 

 the biggest, the shortest of them being a full inch long or 

 more ; and for the execution they do, the trout and grayling 

 being much more greedy of them than of any others ; and 

 indeed the trout never feeds fat, nor comes into his perfect 

 season, till these flies come in. 



Of these the green drake never discloses from his husk 

 till he be first there grown to full maturity, body, wings, and 

 all ; and then he creeps out of his cell, but with his wings 

 so crimpt and ruffled, by being prest together in that narrow 

 room, that they are for some hours totally useless to him ; 

 by which means he is compelled cither to creep upon the 

 flags, sedges, and blades of grass, if his first rising from the 

 bottom of the water be near the banks of the river, till the 

 air and sun stiffen and smooth them ; or, if his first appear- 

 ance above water happen to be in the middle, he then lies 

 upon the surface of the water like a ship at hull ; for his 

 feet are totally useless to him there, and he cannot creep 

 upon the water as the stone-fly can, until his wings have 

 got stiffness to fly with (if by some trout or grayling he be 

 not taken in the interim, which ten to one he is), and then 

 his wings stand high, and closed exact upon his back, like
