So great was his physical strength, that when standing between two hogsheads of tobacco lying on their sides, he could raise or "head" them both up at once. Perhaps it was because he himself rejoiced in such gigantic strength that it was his frequent remark that "it is the strong in body who are both the strong and free in mind." This, too, made him careful to have his young son early instructed in all the manly sports and exercises of his day; so that while still a school-boy he was a good rider, a good swimmer, and an ardent sportsman, spending hours and days wandering in pursuit of game along the sides of the beautiful Southwest Mountains--thus strengthening his body and his health, which must otherwise have given way under the intense application to study to which he soon afterwards devoted himself. The Jeffersons were among the earliest immigrants to the colony, and we find the name in the list of the twenty-two members who composed the Assembly that met in Jamestown in the year 1619--the first legislative body that was ever convened in America.[1] Colonel Jefferson's father-in-law, Isham Randolph, of Dungeness, was a man of considerable eminence in the colony, whose name associated itself in his day with all that was good and wise. In the year 1717 he married, in London, Jane Rogers. Possessing the polished and courteous manners of a gentleman of the colonial days, with a well-cultivated intellect, and a heart in which every thing that is noble and true was instinctive, he charmed and endeared himself to all who were thrown into his society. He devoted much time to the study of science; and we find the following mention of him in a quaint letter from Peter Collinson, of London, to Bartram, the naturalist, then on the eve of visiting Virginia to study her flora: When thee proceeds home, I know no person who will make thee more welcome than Isham Randolph. He lives thirty or forty miles above the falls of James River, in Goochland, above the other settlements. Now, I take his house to be a very suitable place to make a settlement at, for to take several days' excursions all round, and to return to his house at night.... One thing I must desire of thee, and do insist that thee must oblige me therein: that thou make up that drugget clothes, to go to Virginia in, and not appear to disgrace thyself or me; for though I should not esteem thee the less to come to me in what dress thou wilt, yet these Virginians are a very gentle, well-dressed people, and look, perhaps, more at a man's outside than his inside. For these and other reasons, pray go very clean, neat, and handsomely-dressed to Virginia. Never mind thy clothes; I will send thee more another year. [1] The Jeffersons first emigrated to Virginia in 1612.
