This, I am sure, is not talking to you like an old man, though it is talking to you like an old friend; these are not hard conditions to ask of you. I am certain you have sense enough to know how reasonable they are on my part, how advantageous they are on yours: but have you resolution enough to perform them? Can you withstand the examples, and the invitations, of the profligate, and their infamous missionaries? For I have known many a young fellow seduced by a 'mauvaise honte', that made him ashamed to refuse. These are resolutions which you must form, and steadily execute for yourself, whenever you lose the friendly care and assistance of your Mentor. In the meantime, make a greedy use of him; exhaust him, if you can, of all his knowledge; and get the prophet's mantle from him, before he is taken away himself. You seem to like Rome. How do you go on there? Are you got into the inside of that extraordinary government? Has your Abbate Foggini discovered many of those mysteries to you? Have you made an acquaintance with some eminent Jesuits? I know no people in the world more instructive. You would do very well to take one or two such sort of people home with you to dinner every day. It would be only a little 'minestra' and 'macaroni' the more; and a three or four hours' conversation 'de suite' produces a thousand useful informations, which short meetings and snatches at third places do not admit of; and many of those gentlemen are by no means unwilling to dine 'gratis'. Whenever you meet with a man eminent in any way, feed him, and feed upon him at the same time; it will not only improve you, but give you a reputation of knowledge, and of loving it in others. I have been lately informed of an Italian book, which I believe may be of use to you, and which, I dare say, you may get at Rome, written by one Alberti, about fourscore or a hundred years ago, a thick quarto. It is a classical description of Italy; from whence, I am assured, that Mr. Addison, to save himself trouble, has taken most of his remarks and classical references. I am told that it is an excellent book for a traveler in Italy. What Italian books have you read, or are you reading? Ariosto. I hope, is one of them. Pray apply yourself diligently to Italian; it is so easy a language, that speaking it constantly, and reading it often, must, in six months more, make you perfect master of it: in which case you will never forget it; for we only forget those things of which we know but little.
