He was destined to improve English highways, which up to that time had been mostly impossible for wheeled traffic. In France the same advance went on. Arthur Young described the impression made on him in 1789 by the magnificence of the French roads which had been built since the administration of Colbert, as well as by the canal which connected the Mediterranean with the Atlantic. In the midst of this activity Washington grew up. Washington was a born soldier, engineer, and surveyor with the topographical instinct peculiar to that temperament. As early as 1748 he was chosen by Lord Fairfax, who recognized his ability, though only sixteen years old, to survey his vast estate west of the Blue Ridge, which was then a wilderness.
