You will attend at the reviews, see the troops exercised, and inquire into the numbers of troops and companies in the respective regiments of horse, foot, and dragoons; the numbers and titles of the commissioned and non-commissioned officers in the several troops and companies; and also take care to learn the technical military terms in the German language; for though you are not to be a military man, yet these military matters are so frequently the subject of conversation, that you will look very awkwardly if you are ignorant of them.  Moreover, they are commonly the objects of negotiation, and, as such, fall within your future profession.  You must also inform yourself of the reformation which the King of Prussia has lately made in the law; by which he has both lessened the number, and shortened the duration of law-suits; a great work, and worthy of so great a prince!  As he is indisputably the ablest prince in Europe, every part of his government deserves your most diligent inquiry, and your most serious attention.  It must be owned that you set out well, as a young politician, by beginning at Berlin, and then going to Turin, where you will see the next ablest monarch to that of Prussia; so that, if you are capable of making political reflections, those two princes will furnish you with sufficient matter for them.

I would have you endeavor to get acquainted with Monsieur de Maupertuis, who is so eminently distinguished by all kinds of learning and merit, that one should be both sorry and ashamed of having been even a day in the same place with him, and not to have seen him.  If you should have no other way of being introduced to him, I will send you a letter from hence.  Monsieur Cagenoni, at Berlin, to whom I know you are recommended, is a very able man of business, thoroughly informed of every part of Europe; and his acquaintance, if you deserve and improve it as you should do, may be of great use to you.

Remember to take the best dancing-master at Berlin, more to teach you to sit, stand, and walk gracefully, than to dance finely.  The Graces, the Graces; remember the Graces!  Adieu!

LETTER LXIII

London, January 24, O. S. 1749.

Dear boy:  I have received your letter of the 12th, N. S., in which I was surprised to find no mention of your approaching journey to Berlin, which, according to the first plan, was to be on the 20th, N. S., and upon which supposition I have for some time directed my letters to you, and Mr. Harte, at Berlin.  I should be glad that yours were more minute with regard to your motions and transactions; and I desire that, for the future, they may contain accounts of what and who you see and hear, in your several places of residence; for I interest myself as much in the company you keep, and the pleasures you take, as in the studies you pursue; and therefore, equally desire to be informed of them all.  Another thing I desire, which is, that you will acknowledge my letters by their dates, that I may know which you do, and which you do not receive.
