John Adams Diary:
Thursday, 29 May 1760: I must run over Fractions again, vulgar and Decimal, as well as algebraical, and now and then, a few Questions in Fenning and Hammond, and Ward, or else I shall totally forget my Numbers. I find that the Art of numbering depends upon Practice, and in a short disuse, they will slip from the Memory. A Journal, scrawled with Algebraical signs, and interspersed with Questions of Law, Husbandry, natural History &c., will be a useful Thing.

The Principal Uses however will be to correct and my style, and assist my Memory, and give me a true Compunction for the Waste of Time, and urge me of Course to a better Improvement of it. Besides Writing is one of the greatest Pleasures, and it sooner rouses my ambition, warms my Imagination, and fixes me in do-than sitting still with my Eyes shut, or than holding a Book to read.
