If you have time to read at Hanover, pray let the books you read be all relative to the history and constitution of that country; which I would have you know as correctly as any Hanoverian in the whole Electorate. Inform yourself of the powers of the States, and of the nature and extent of the several judicatures; the particular articles of trade and commerce of Bremen, Harburg, and Stade; the details and value of the mines of the Hartz. Two or three short books will give you the outlines of all these things; and conversation turned upon those subjects will do the rest, and better than books can. Remember of all things to speak nothing but German there; make it (to express myself pedantically) your vernacular language; seem to prefer it to any other; call it your favorite language, and study to speak it with purity and elegance, if it has any. This will not only make you perfect in it, but will please, and make your court there better than anything. A propos of languages: Did you improve your Italian while you were at Paris, or did you forget it? Had you a master there? and what Italian books did you read with him? If you are master of Italian, I would have you afterward, by the first convenient opportunity, learn Spanish, which you may very easily, and in a very little time do; you will then, in the course of your foreign business, never be obliged to employ, pay, or trust any translator for any European language. As I love to provide eventually for everything that can possibly happen, I will suppose the worst that can befall you at Hanover. In that case I would have you go immediately to the Duke of Newcastle, and beg his Grace's advice, or rather orders, what you should do; adding, that his advice will always be orders to you. You will tell him that though you are exceedingly mortified, you are much less so than you should otherwise be, from the consideration that being utterly unknown to his M-----, his objection could not be personal to you, and could only arise from circumstances which it was not in your power either to prevent or remedy; that if his Grace thought that your continuing any longer there would be disagreeable, you entreated him to tell you so; and that upon the whole, you referred yourself entirely to him, whose orders you should most scrupulously obey. But this precaution, I dare say, is 'ex abundanti', and will prove unnecessary; however, it is always right to be prepared for all events, the worst as well as the best; it prevents hurry and surprise, two dangerous, situations in business; for I know no one thing so useful, so necessary in all business, as great coolness, steadiness, and sangfroid: they give an incredible advantage over whoever one has to do with.
