Fig. 2.—Haulage of Vehicles. But, as the disposition of the load is such that 10 lbs. are taken from the horse, it is obvious that, if only lbs. are put back by the stated pull of 36 lbs., the horse has still lbs. less than his natural weight in Fig. 2, while in Fig. i he has 4 lbs. more than his natural Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Thurston, Robert Henry, 1839-1903.
