There is also another _Cadis_ called by some a _Straw-worm_, and by some a _Russe-coate_, 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 condens'd slime, that they stick up about her husk or case, not unlike the _bristles_ of a _Hedg-hog_; these three _Cadis_ are commonly taken in the beginning of Summer, and are good indeed to take any kind of fish with flote or otherwise, I might tell you of many more, which, as these doe early, so those have their time of turning to be flies later in Summer; but I might lose my selfe, 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 bee _Cadis_, and then as they be flies, is an Art, and an Art that every one that professes Angling is not capable of.

But let mee 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 shall ever like to do so, then note, that your stick must be cleft, or have a nick at one end of it, by which meanes you may with ease take many of them out of the water, before you have any occasion to use them. These, my honest Scholer, 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 that must do it.

_Pisc_. Well, Scholar, I have held you too long about these _Cadis_, and my spirits are almost spent, and so I doubt is your patience; but being we are now within sight of _Totenham_, where I first met you, and where wee are to part, I will give you a little direction how to colour the hair of which you make your lines, for that is very needful to be known of an _Angler_; and also how to paint your rod, especially your top, for a right grown top is a choice Commoditie, and should be preserved from the water soking into it, which makes it in wet weather to be heavy, and fish ill favouredly, and also to rot quickly.
