By the American Railroad Journal andAdvocate of Internal Improvements.]In No. 23, Scientific Tracts, it is statedthat a horse, at five miles an hour, usuallyexerts the force necessary to raise 45 a pulley, and draws on a level railroadabout four tons. At two miles an hour, heusually exerts a force necessary to raise 112pounds, and draws on a level railroad about10 tons. It is computed that a man candraw on a horizontal line about one-sevenththe load a horse can draw; and therefore, hecould draw at two miles an hour 29 cwt., ormore than two horses could draw on a road at four miles an hour,—and more.
