“ It cannot but be known, that liberty, so dear to us, and to every part of the creation, must be equally so to the horse: to have his limbs free from restraint, to expand his frame, and roll upon the earth, to snort and snuff the ambient air, and to have his coat cleansed and purified by the dew of heaven, is to the horse a state of nature, and a life of luxury. Thus free and uncontrouled, although they are equally subject to, yet they are seldom known to be afflicted with pain or disease, in any degree equal to those who are confined within the limits of a small and offensive stable. ”
