This day completes three years since I stepped into the coach at Mr. Cushing's door, in Boston, to go to Philadelphia in quest of adventures. And adventures I have found. I feel an inclination sometimes to write the history of the last three years, in imitation of Thucydides. There is a striking resemblance in several particulars between the Peloponnesian and the American war. The real motive to the former was a jealousy of the growing power of Athens by sea and land. The genuine motive to the latter was a similar jealousy of the growing power of America. The true causes which incite to war are seldom professed or acknowledged. We are now upon a full sea; when we shall arrive at a safe harbor, no mariner has skill and experience enough to foretell. But by the favor of Heaven we shall make a prosperous voyage, after all the storms and shoals are passed. 5 o'clock, Afternoon. It is now fair sunshine again, and very warm. Not a word yet from Howe's fleet. The most general suspicion now is that it is gone to Charleston, South Carolina. But it is a wild supposition. It may be right, however, for he is a wild General. We have been hammering to-day upon a mode of trial for the general officers at Ti. Whether an inquiry will precede the court martial, and whether the inquiry shall be made by a committee of Congress or by a council of general officers, is not determined, but inquiry and trial both, I conjecture, there will be. If Howe is gone to Charleston, you will have a little quiet, and enjoy your corn, and rye, and flax, and hay, and other good things, until another summer. But what shall we do for sugar and wine and rum? Why, truly, I believe we must leave them off. Loaf sugar is only four dollars a pound here, and brown only a dollar for the meanest sort, and ten shillings for that a little better. Everybody here is leaving off loaf sugar, and most are laying aside brown. As to rum and wine, give me cider and I would compound. New England rum is but forty shillings a gallon. But if wine was ten dollars a bottle I would have one glass a day in water while the hot weather continues, unless I could get cider. 199. JOHN ADAMS. Philadelphia, Thursday, 21 August, 1777.
