DIET.--He tells me that you are pretty fat for one of your age; this you should attend to in a proper way; for if, while very young, you should grow fat, it would be troublesome, unwholesome, and ungraceful; you should therefore, when you have time, take very strong exercise, and in your diet avoid fattening things. All malt liquors fatten, or at least bloat; and I hope you do not deal much in them. [_Same date._] BE NATURAL.--I have this moment received your letter of the 4th, N. S., and have only time to tell you, that I can by no means agree to your cutting off your hair. I am very sure that your headaches cannot proceed from thence. And as for the pimples upon your head, they are only owing to the heat of the season; and consequently will not last long. But your own hair is, at your age, such an ornament, and a wig, however well made, such a disguise, that I will upon no account whatsoever have you cut off your hair. Nature did not give it you for nothing, still less to cause you the headache. Mr. Eliot’s hair grew so ill and bushy, that he was in the right to cut it off; but you have not the same reason. [_Same date._] BUYING BOOKS.--Mr. Harte wrote me word some time ago, and Mr. Eliot confirms it now, that you employ your pin-money in a very different manner from that in which pin-money[35] is commonly lavished. Not in gewgaws and baubles, but in buying good and useful books. This is an excellent symptom, and gives me very good hopes. Go on thus, my dear boy, but for these two next years, and I ask no more. You must then make such a figure, and such a fortune in the world, as I wish you, and as I have taken all these pains to enable you to do. After that time, I allow you to be as idle as ever you please; because I am sure that you will not then please to be so at all. The ignorant and the weak only are idle; but those, who have once acquired a good stock of knowledge, always desire to increase it. Knowledge is like power, in this respect, that those who have the most, are most desirous of having more. It does not clog, by possession, but increases desires; which is the case of very few pleasures. [_Aug. 23, 1748._] GRATITUDE TO A TUTOR.--Upon receiving this congratulatory letter, and reading your own praises, I am sure that it must naturally occur to you, how great a share of them you owe to Mr. Harte’s care and attention; and, consequently, that your regard and affection for him must increase, if there be room for it, in proportion as you reap, which you do daily, the fruits of his labors.
