Manners, though the last, and it may be the least ingredient of real merit, are, however, very far from being useless in its composition; they adorn, and give an additional force and luster to both virtue and knowledge.  They prepare and smooth the way for the progress of both; and are, I fear, with the bulk of mankind, more engaging than either.  Remember, then, the infinite advantage of manners; cultivate and improve your own to the utmost good sense will suggest the great rules to you, good company will do the rest.  Thus you see how much you have to do; and how little time to do it in:  for when you are thrown out into the world, as in a couple of years you must be, the unavoidable dissipation of company, and the necessary avocations of some kind of business or other, will leave you no time to undertake new branches of knowledge:  you may, indeed, by a prudent allotment of your time, reserve some to complete and finish the building; but you will never find enough to lay new foundations.  I have such an opinion of your understanding, that I am convinced you are sensible of these truths; and that, however hard and laborious your present uninterrupted application may seem to you, you will rather increase than lessen it.  For God’s sake, my dear boy, do not squander away one moment of your time, for every moment may be now most usefully employed.  Your future fortune, character, and figure in the world, entirely depend upon your use or abuse of the two next years.  If you do but employ them well, what may you not reasonably expect to be, in time?  And if you do not, what may I not reasonably fear you will be?  You are the only one I ever knew, of this country, whose education was, from the beginning, calculated for the department of foreign affairs; in consequence of which, if you will invariably pursue, and diligently qualify yourself for that object, you may make yourself absolutely necessary to the government, and, after having received orders as a minister abroad, send orders, in your turn, as Secretary of State at home.  Most of our ministers abroad have taken up that department occasionally, without having ever thought of foreign affairs before; many of them, without speaking any one foreign language; and all of them without manners which are absolutely necessary toward being well received, and making a figure at foreign courts.  They do the business accordingly, that is, very ill:  they never get into the secrets of these courts, for want of insinuation and address:  they do not guess at their views, for want of knowing their interests:  and, at last, finding themselves very unfit for, soon grow weary of their commissions, and are impatient to return home, where they are but too justly laid aside and neglected.  Every moment’s conversation may, if you please, be of use to you; in this view, every public event, which is the common topic of conversation, gives you an opportunity of getting some information.  For example, the preliminaries of peace, lately concluded
