“ Notwithstanding all these precautions, however, there were still some inconveniences resulting from the nature of the blanket placed under the saddle, which I sought to remedy, and I easily accomplished it. The woolen nap of the cavalry saddle-blankets, not being carefully attended to, soon wears off, and leaves only the rough, coarse threads of the fabric; this absorbs the sweat from the horse, and, after it has dried and become hard, it acts like a rasp upon the withers, first taking off the hair, next the skin, and then the flesh, and, finally, the beast is rendered unserviceable. ”
