The official report of an agricultural committee in South Carolina, in 1824, says:--"The annual expense of keeping a horse is equal to his value. A horse at four years old would not often bring more than his cost. Two mules can be raised at less expense than one horse. The mule is fit for service earlier, and if of sufficient size, will perform as much labor as the horse; and if attended to when first put to work, his gait and habits may be formed to suit the owner." Mr. Pomeroy, who used them near Boston for 30 years, and to such an extent as to have had more labor performed by them probably than any person in New England, says:--"I am convinced the small breed of mules will consume less in proportion to the labor they are capable of performing than the larger race, but I shall confine myself to the latter in my comparison, such as stand 14½ to 16 hands, and are capable of performing any work a horse is usually put to. From repeated experiments, I have found that three mules of this description, which were constantly at work, consumed about the same quantity of hay, and only one-fourth the provender, which was given to two middling-size coach-horses, only moderately worked. I am satisfied a large-sized mule will not consume more than three-fifths to two-thirds the food to keep him in good order, that will be necessary for a horse performing the same labor. The expense of shoeing a mule the year round, does not exceed one-third that of the horse, his hoofs being harder, more horny, and so slow in their growth, that shoes require no removal, and hold on till worn out; and the wear from the lightness of the animal is much less. Mules have been lost by feeding on cut straw and corn meal; in no other instance have I known disease in them, except by inflammation of the intestines, caused by the grossest exposure to cold and wet, and excessive drinking cold water, after severe labor, and while in a high state of perspiration. It is not improbable a farmer may work the same team of mules for twenty years, without having a farrier's bill presented to him. In my experience of thirty years, I have never found but one mule inclined to be vicious, and he might have been easily subdued while young. I have always found them truer pullers and quicker travellers, with a load, than horses. Their vision and hearing are much more accurate. I have used them in my family carriage, in a gig, and under the saddle; and have never known one to start or run from any object or noise, a fault in the horse, that continually causes the maiming and death of numerous human beings.
