There is also another cadis, called by some a Straw-worm, and by some a Ruff-coat, whose house, or case, is made of little pieces of bents, and rushes, and straws, and water-weeds, and I know not what; which are so knit together with condensed slime, that they stick about her husk or case, not unlike the bristles of a hedge-hog.These three cadises are commonly taken in the beginning of summer; and are good, indeed, to take any kind of fish, with float or otherwise.I might tell you of many more, which as they do early, so those have their time also of turning to be flies in later summer; but I might lose myself, and tire you, by such a discourse: I shall therefore but remember you, that to know these, and their several kinds, and to what flies every particular cadis turns, and then how to use them, first as they be cadis, and after as they be flies, is an art, and an art that every one that professes to be an angler has not leisure to search after, and, if he had, is not capable of learning.
I'll tell you, scholar; several countries have several kinds of cadises, that indeed differ as much as dogs do; that is to say, as much as a very cur and a greyhound do.These be usually bred in the very little rills, or ditches, that run into bigger rivers; and I think a more proper bait for those very rivers than any other.I know not how, or of what, this cadis receives life, or what coloured fly it turns to; but doubtless they are the death of many Trouts: and this is one killing way:
Take one, or more if need be, of these large yellow cadis: pull off his head, and with it pull out his black gut; put the body, as little bruised as is possible, on a very little hook, armed on with a red hair, which will shew like the cadis-head; and a very little thin lead, so put upon the shank of the hook that it may sink presently.Throw this bait, thus ordered, which will look very yellow, into any great still hole where a Trout is, and he will presently venture his life for it, it is not to be doubted, if you be not espied; and that the bait first touch the water before the line.And this will do best in the deepest stillest water.
Next, let me tell you, I have been much pleased to walk quietly by a brook, with a little stick in my hand, with which I might easily take these, and consider the curiosity of their composure: and if you should ever like to do so, then note, that your stick must be a little hazel, or willow, cleft, or have a nick at one end of it, by which means you may, with ease, take many of them in that nick out of the water, before you have any occasion to use them.These, my honest scholar, are some observations, told to you as they now come suddenly into my memory, of which you may make some use: but for the practical part, it is that that makes an angler: it is diligence, and observation, and practice, and an ambition to be the best in the art, that must do it.I will tell you, scholar, I once heard one say, " I envy not him that eats better meat than I do; nor him that is richer, or that wears better clothes than I do: I envy nobody but him, and him only, that catches more fish than I do ".And such a man is like to prove an angler; and this noble emulation I wish to you, and all young anglers.
