I thought it worthy of taking notice of a singular method the traders make use of to reduce the wild young horses to their hard duty. When any one persists in refusing to receive his load, if threats, the discipline of the whip and other common abuse prove insufficient, after being haltered, a pack-horseman catches the tip end of one of his ears betwixt his teeth and pinches it, when instantly the furious strong creature, trembling, stands perfectly still until he is loaded.
