_I thought my self secure, for I could top, By which I've forc’d some Citt’s to leave their shop. I palm’d, and put the change upon them too, I only studied how I might undo. But now I'm met with, 'tis but just I see, That he which others cheats should cheated be._ He being clear of these two crimes, Thieving and Cheating (which are the most Capital,) I know not why he should be avoided for any other, though we suppose him guilty of many female frauds, his inclination leading him to be a lover (though Mercurial and unconstant) of the Female sex; with whom I suppose he may have acted some of the adventures by him recited, and those passages, with what others he thought or heard of: and whereof many persons in this our age are guilty, he having methodiz’d, is the main part of his Book; and the intent of his writing, it was to shew the deformity of vice, that every one might shun it. The two lines which he placed on the Title page of many of his Books, sufficiently demonstrating the Authors intent. The words are these, _Read, but don't practice: since the Author finds They which live honest, have most quiet minds._ Thus, although the intent of his writing was good, and the effects proved answerable in the sale of the Book, yet could I not procure him to proceed, though I offered him my assistance, in acquainting him with my experience; but all would not do: Wherefore I applyed my self to another, a brother of the same trade; a professed Author, and one who hath been happy enough in the sale of many of his writings; him I courted into a complyance with my desire, and perswaded to begin to write somewhat to the purpose; I proposing only to him to give an account of the knavery of many trades and professions. I gave him my best instructions, and laid my ground-work well enough, as I hoped to have him proceed: But so soon as he knew my intention of making his writing a part of (by joyning it to) _The Rogue_, with some anger he left it, and refused to proceed. He having thus laid down the Cudgels, I then took them up my self, and those loose scribled papers which I had written for his instruction to proceed upon, I viewed over, and after some small correction they serve for the greatest part of this Treatise.
