I need hardly say that horses with toe-pieces to their fore shoes can, while retaining their foothold, biing the centie of giavity faither beyond the base of support, by the slope of the fore leg which rests on the ground, than they could do with flat shoes; supposing, of couise, that the surface of the ground was not abnormally smooth and hard, like wood or asphalt. From the foregoing considerations we may draw, with respect to cart-horses that are required to exert their strength to the utmost, the following deductions, which are fairly self-evident to practical men. I. Bodily weight, especially in the fore hand, is an advantage m draught;. Fig. 42.—Mechanism of Draught. (From Colm's Physiologk Comparie?^ for the greater it is, the more effective will be the push against the collar caused by the centre of gravity falling beyond the base of support. Agreeably to this fact, the experienced driver of a heavily-laden two-wheeled cart will endeavour to place a fair share of the burden on the animal's back, so that the horse may pull to the best advantage. The experiment of a man succeeding in pulling along a stronger man than himself, by trying to do so, while carrying a heavy weight on his back, is another familiar instance of this principle. The gain in power from increased weight on the fore hand is, also, well illustrated by the practice, which is not very uncommon among drivers of one-horse carts, of the driver mounting his animal and getting well forward on its back, when he finds that it is unable to pull its load up a hill.
