STALL.—The partitions into which a stable is divided are denominated STALLS; and the space allotted to each horse is called a stall. These, in stables constructed with judgment, and erected with a necessary respect to health and convenience, should never be less than nine or ten feet high, and six feet wide: the heighth will contribute much to the equal temperature of the air; and the width will contribute to the comfort of the horse in an occasional extension of his extremities, as well as prevent many of those injuries sustained in too suddenly turning in narrow and confined stalls, particularly in the common livery stables of the Metropolis. In many large equestrian and hunting establishments there are single stalls (called loose boxes) of such dimensions as are adapted to the accommodation of horses either _sick_ or _lame_, where they are then at liberty to expand at full length, and enabled to roll at their ease: these are of great utility, and few sportsmen continue long without them. STALLION—is the appellation given to a perfect horse, not mutilated by the operation of _castration_, but preserved in a state of nature, for the purpose of propagation. Stallions should be of great strength, according to the distinct breed they are intended to promote, of correct shape, uniform make, and corresponding symmetry; free from every kind of hereditary taint; good eyes, long forehand, short back, round barrel, wide chest, straight legs, free from splents before, and spavins behind. Although it is a difficult task to obtain perfection, some little circumspection may be necessary, in coming as near to it as circumstances and situation will permit. Experimental observation has produced demonstration, that stallions really blind, or with eyes defective, have produced colts of similar description; such defects not appearing in their first _two_ or _three_ years, nor, indeed, till they have been worked, and the powers brought into action. Instances are never wanting of the great number annually disposed to breed, who as annually _repent_ for want of these prudent precautions. Not only the above points, but the temper and disposition of a stallion should be also attended to: vicious and restive horses should be equally avoided; those imperfections are very frequently transmitted from _sire_ to _son_, and continued to posterity.
