Summary

A whip for the horse, a bridle for the ass, and a rod for the fool's back.

According to our notions, we should rather say, a bridle for the horse, and a whip for the ass; but it should be considered, that the eastern asses are not only much more beautiful, but better goers that ours; and being active and well broken, they need only a bridle to guide them; whereas their horses being scarce, and often caught wild, and badly broken, are much less manageable, and need the correction of the whip
