A part of a horse's harness which surrounds his neck, and to which the traces are attached by which he draws. It ordinarily consists of a stuffed leather pad, on which rest two curved bars called the hames, united at the lower ends by a few links of chain, and drawn together at top by a strap and buckle; but from the collapsing of the hames, the shoulders of the horses frequently become rung, which induces many to give the preference to breastings rather than collars. In Mr. Lukin's improved horse collars the hame is made in one piece, which, from its elasticity, has a tendency to expand instead of collapsing, and the pads upon it are not fixed immovably, but turn round upon the hames as an axis, by which means the pressure adapts itself to the motion of the horse, and materially reduces the chafing against his shoulders. The annexed cut represents one of these collars, a a represent the pads, one turned partly round upon the hames b b b to show their action; c c are clips for the traces; d a small pad which lies over the horse's neck, and e the strap by which the hames are contracted in any required degree.
