I must not omit mentioning to you, that at the Duke of Newcastle's table, where you will frequently dine, there is a great deal of drinking; be upon your guard against it, both upon account of your health, which would not bear it, and of the consequences of your being flustered and heated with wine: it might engage you in scrapes and frolics, which the King (who is a very sober man himself) detests. On the other hand, you should not seem too grave and too wise to drink like the rest of the company; therefore use art: mix water with your wine; do not drink all that is in the glass; and if detected, and pressed to drink more do not cry out sobriety; but say that you have lately been out of order, that you are subject to inflammatory complaints, and that you must beg to be excused for the present. A young fellow ought to be wiser than he should seem to be; and an old fellow ought to seem wise whether he really' be so or not. During your stay at Hanover I would have you make two or three excursions to parts of that Electorate: the Hartz, where the silver mines are; Gottingen, for the University; Stade, for what commerce there is. You should also go to Zell. In short, see everything that is to be seen there, and inform yourself well of all the details of that country. Go to Hamburg for three or four days, and know the constitution of that little Hanseatic Republic, and inform yourself well of the nature of the King of Denmark's pretensions to it. If all things turn out right for you at Hanover, I would have you make it your head-quarters, till about a week or ten days before the King leaves it; and then go to Brunswick, which, though a little, is a very polite, pretty court. You may stay there a fortnight or three weeks, as you like it; and from thence go to Cassel, and stay there till you go to Berlin; where I would have you be by Christmas. At Hanover you will very easily get good letters of recommendation to Brunswick and to Cassel. You do not want any to Berlin; however, I will send you one for Voltaire. 'A propos' of Berlin, be very reserved and cautious while at Hanover, as to that King and that country; both which are detested, because feared by everybody there, from his Majesty down to the meanest peasant; but, however, they both extremely deserve your utmost attention and you will see the arts and wisdom of government better in that country, now, than in any other in Europe. You may stay three months at Berlin, if you like it, as I believe you will; and after that I hope we shall meet there again.
