Friedrich Gerstäcker, in one of his most delightful moods, says somewhere that the best characteristicon of a man is how he wears his hat. If he wears it perpendicular, he is honest, pedantic, and boresome. If he wears it tipped slightly, he belongs to the best and most interesting people, is nimble-witted and pleasant. A deeply tipped hat indicates frivolity and obstinate imperious nature. A hat worn on the back of the head signifies improvidence, easiness, conceit, sensuality and extravagance; the farther back the more dangerous is the position of the wearer. The man who presses his hat against his temples complains, is melancholy, and in a bad way. It is now many years since I have read this exposition by the much-traveled and experienced author, and I have thought countless times how right he was, but also, how there may be numberless similar marks of recognition which show as much as the manner of wearing a hat. There are plenty of similar expositions to be known; one man seeks to recognize the nature of others by their manner of wearing and using shoes; the other by the manipulation of an umbrella; and the prudent mother advises her son how the candidate for bride behaves toward a groom lying on the floor, or how she eats cheese--the extravagant one cuts the rind away thick, the miserly one eats the rind, the right one cuts the rind away thin and carefully. Many people judge families, hotel guests, and inhabitants of a city, and not without reason, according to the comfort and cleanliness of their privies.
