Pray make my compliments to Mr. Harte, and tell him I have received his letter from Vienna of the 16th N. S., but that I shall not trouble him with an answer to it till I have received the other letter which he promises me, upon the subject of one of my last. I long to hear from him after your settlement at Turin: the months that you are to pass there will be very decisive ones for you. The exercises of the Academy, and the manners of courts must be attended to and acquired; and, at the same time, your other studies continued. I am sure you will not pass, nor desire, one single idle hour there: for I do not foresee that you can, in any part of your life, put out six months to greater interest, than those next six at Turin.
We will talk hereafter about your stay at Rome and in other parts of Italy. This only I will now recommend to you; which is, to extract the spirit of every place you go to. In those places which are only distinguished by classical fame, and valuable remains of antiquity, have your classics in your hand and in your head; compare the ancient geography and descriptions with the modern, and never fail to take notes. Rome will furnish you with business enough of that sort; but then it furnishes you with many other objects well deserving your attention, such as deep ecclesiastical craft and policy. Adieu.
