This walking hero [Daniel Crisp] on Sept. 21, 1802, walked one mile in seven minutes and fifty seconds, on the City-road, London.—July 16, 1817, commenced walking backwards forty miles daily for seven days, and completed 280 miles by that retrograde motion, on Wormwood Scrubs, near London, one hour and a quarter within the given time, to the surprise of thousands who witnessed the performance. … April 23, 1818, commenced walking from London to Oxford, to and fro by way of Datchet, Windsor, and Henley, the distance of sixty-one miles daily for seventeen successive days, and completed the 1037 miles on the 9th of May at eight minutes after eleven at night, being fifty-two minutes within the given time; during the performance of this arduous undertaking it rained heavily for ten days, which caused the Thames to overflow on the road to the depth of two feet and a half, and a quarter of a mile in length, which he was obliged to walk through for five days.
