METHOD OF STUDY--THE WORLD AND BOOKS.--Your first morning hours, I would have you devote to your graver studies with Mr. Harte; the middle part of the day, I would have employed in seeing things; and the evenings, in seeing people. You are not, I hope, of a lazy, inactive turn, in either body or mind; and, in that case, the day is full long enough for everything; especially at Rome, where it is not the fashion, as it is here and at Paris, to embezzle at least half of it at table. But if, by accident, two or three hours are sometimes wanting for some useful purpose, borrow them from your sleep. Six, or at most seven hours’ sleep is, for a constancy, as much as you or anybody can want: more is only laziness and dozing; and is, I am persuaded, both unwholesome and stupefying. If, by chance, your business, or your pleasures, should keep you up till four or five o’clock in the morning, I would advise you, however, to rise exactly at your usual time, that you may not lose the precious morning hours; and that the want of sleep may force you to go to bed earlier the next night. This is what I was advised to do when very young, by a very wise man; and what, I assure you, I always did in the most dissipated part of my life. I have very often gone to bed at six in the morning, and rose, notwithstanding, at eight; by which means I got many hours, in the morning, that my companions lost; and the want of sleep obliged me to keep good hours the next, or at least the third night. To this method I owe the greatest part of my reading; for, from twenty to forty, I should certainly have read very little, if I had not been up while my acquaintances were in bed. Know the true value of time; snatch, seize, and enjoy every moment of it. No idleness, no laziness, no procrastination: never put off till to-morrow what you can do to-day. That was the rule of the famous and unfortunate pensionary De Witt; who, by strictly following it, found time, not only to do the whole business of the republic, but to pass his evenings at assemblies and suppers, as if he had nothing else to do or think of.
