But I insist upon it that pleasures are very combinable with both business and studies, and have a much better relish from the mixture.  The man who cannot join business and pleasure is either a formal coxcomb in the one, or a sensual beast in the other.  Your evenings I therefore allot for company, assemblies, balls, and such sort of amusements, as I look upon those to be the best schools for the manners of a gentleman; which nothing can give but use, observation, and experience.  You have, besides, Italian to learn, to which I desire you will diligently apply; for though French is, I believe, the language of the court at Turin, yet Italian will be very necessary for you at Rome, and in other parts of Italy; and if you are well grounded in it while you are at Turin (as you easily may, for it is a very easy language), your subsequent stay at Rome will make you perfect in it.  I would also have you acquire a general notion of fortification; I mean so far as not to be ignorant of the terms, which you will often hear mentioned in company, such as ravelin, bastion; glacis, contrescarpe, etc.  In order to this, I do not propose that you should make a study of fortification, as if you were to be an engineer, but a very easy way of knowing as much as you need know of them, will be to visit often the fortifications of Turin, in company with some old officer or engineer, who will show and explain to you the several works themselves; by which means you will get a clearer notion of them than if you were to see them only upon paper for seven years together.  Go to originals whenever you can, and trust to copies and descriptions as little as possible.  At your idle hours, while you are at Turin, pray read the history of the House of Savoy, which has produced a great many very great men.  The late king, Victor Amedee, was undoubtedly one, and the present king is, in my opinion, another.  In general, I believe that little princes are more likely to be great men than those whose more extensive dominions and superior strength flatter them with a security, which commonly produces negligence and indolence.  A little prince, in the neighborhood of great ones, must be alert and look out sharp, if he would secure his own dominions:  much more still if he would enlarge them.  He must watch for conjunctures or endeavor to make them.  No princes have ever possessed this art better than those of the House of Savoy; who have enlarged their dominions prodigiously within a century by profiting of conjunctures.

I send you here inclosed a letter from Comte Lascaris, who is a warm friend of yours:  I desire that you will answer it very soon and cordially, and remember to make your compliments in it to Comte du Perron.  A young man should never be wanting in those attentions; they cost little and bring in a great deal, by getting you people’s good word and affection.  They gain the heart, to which I have always advised you to apply yourself particularly; it guides ten thousand for one that, reason influences.
