A boy is generally employed to go with a cart, and his strength is frequently not sufficient to raise the cart so as to tilt and preserve the proper level in vibram five fingers descending hills ; now, by means of the winch, the boy is able to easily accomplish this.4th. Tlw height of the Cart and position of Shafts.We have already stated our opinion to be in favour of low carts, inasmuch as they are steadier and easier to fill. Still there are some arguments to be urged in favour of high carts. To apply the force of the horse most economically the vibram fivefingers shafts should be of such a height that when the horse is drawing the shoulderchain and shaft shall be in one straight line. In fact the axle of the cart or centre of the weight should form a straight line with the shoulder-chain of the horse, or the point at which the power is applied. If the shaft be too high or too low the chain will meet at an angle and cause a waste of power. It is therefore clear on good level roads the horse draws his load with the greatest ease when the shafts are nearly level. But in ascending a hill, or on rough ground, the case is different; the centre of gravity being more elevated, the load is more quickly thrown out of balance with a high cart than a low. Moreover, it is an advantage to the horse on hilly ground to bear some portion of the weight on his back, since it increases his weight, and consequently his power of traction ; therefore, for farm purposes a low cart, and for level road-work a high cart is best All that has been advanced in favour of a low cart applies with still more force to harvest carts. five fingers shoes The difficulty of keeping the load steady, in consequence of an elevated centre of gravity, has in many instances in hilly districts induced the use of waggons for harvesting purposes. Where the carts are kept low and wide, carts may be with safety used for harvesting purposes. It is true that in a cart the load is exposed to more jerks than in a waggon, since a portion of the load in the former is borne on the horse's back, and must necessarily partake of the unsteadiness of his motion. Where the harvesting frame consists of two or three parallel or horizontal bars, small loads can only be taken at a time. It increases the power of cohesion of the load to have only one bar at the front and vibram five fingers kso back, since the sheaves are bent over the single bar by the weight of the load, and thus obtain a firmer hold. The best mode of keeping the load steady and secure is by the use of curved raves, as in Crosskill's, Busby's, and Fry's Newport cart With these raised ends and sides the motion of the cart tends to condense the load.
