Since cropping is to be adopted not for the sake of elegance, but on account of the necessity of the case; the hair of the head, that it may not grow so long as to come down and interfere with the eyes, and that of the moustache similarly, which is dirtied in eating, is to be cut round, not by the razor, for that were ungenteel, but by a pair of cropping scissors. But the hair on the chin is not to be disturbed, as it gives no trouble, and lends to the face dignity and paternal terror.
