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

 our Cadis or Cod-bait, which lie under stones in 

 the bottom of the water, most of them turning into

 crust, near the time of their maturity, are very 

 easily known and distinguished ; and are of all

Of these, the Green-drake never discloses from 

 his husk, till he be first there grown to full matu-
