the King of Sardinia, are, by these preliminaries, confirmed and secured
to him: you will inquire, therefore, what they are, and what they are
worth. This is the kind of knowledge which you should be most thoroughly
master of, and in which conversation will help you almost as much as
books: but both are best. There are histories of every considerable
treaty, from that of Westphalia to that of Utrecht, inclusively; all
which I would advise you to read. Pore Bougeant's, of the treaty of
Westphalia, is an excellent one; those of Nimeguen, Ryswick, and Utrecht,
are not so well written; but are, however, very useful. 'L'Histoire des
Traites de Paix', in two volumes, folio, which I recommended to you some
time ago, is a book that you should often consult, when you hear mention
made of any treaty concluded in the seventeenth century.

Upon the whole, if you have a mind to be considerable, and to shine
hereafter, you must labor hard now. No quickness of parts, no vivacity,
will do long, or go far, without a solid fund of knowledge; and that fund
of knowledge will amply repay all the pains that you can take in
acquiring it. Reflect seriously, within yourself, upon all this, and ask
yourself whether I can have any view, but your interest, in all that I
recommend to you. It is the result of my experience, and flows from that
tenderness and affection with which, while you deserve them, I shall be,
Yours.

Make my compliments to Mr. Harte, and tell him that I have received his
letter of the 24th, N. S.
