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 at Aix-la-Chapelle,will be the common subject of most conversations;in which you will take care to ask the proper questions:as,what is the meaning of the Assiento contract for negroes,between England and Spain;what the annual ship;when stipulated;upon what account suspended,etc.You will likewise inform yourself about Guastalla,now given to Don Philip,together with Parma and Placentia;who they belonged to before;what claim or pretensions Don Philip had to them;what they are worth;in short,everything concerning them.The cessions made by the Queen of Hungary to 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 Irecommend 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.
