MOUTH
.—The good or bad mouth of a horse depends upon the pliability of his temper, and his obedience to the bit. Some horses (particularly those of violent and refractory dispositions) are so truly insensible to every effort of even the best riders, that hardly any kind of bit can be invented to reduce them to subjection; while, on the contrary, there are those, and even blood horses, of such good temper, and constitutional docility; that they may be regulated instantaneously to any purpose, by the most tender bearing of a common snaffle.
