On the crowded walk, if two acquaintances pass and re-pass each other several times in the course of the same promenade, it is not necessary to exchange greetings after the first meeting.
Canes and umbrellas should not be carried under the arm horizontally, endangering the eyes and ribs of other pedestrians.
A man, when bowing, lifts his hat in the following instances:
When bowing to a lady.
When, walking with a lady, he bows to another man of his acquaintance.
When bowing to an elderly man, or a superior in office.
When bowing to a man who is walking with a lady.
When, walking with a lady, he joins her in saluting any gentlemen of her acquaintance, but strangers to himself; or, when walking with gentlemen, he joins them in saluting a lady of their acquaintance, but a stranger to himself.
When offering any civility (as a seat in the street-car), to a lady, whether a stranger or an acquaintance.
When bidding good-bye to a lady after an "open-air" conference, when the hat has been worn. Punctilious etiquette requires a man to stand with head uncovered in the presence of ladies, until requested to replace the hat. But in our changeable climate, the risk of "taking cold" suggests the good sense of wearing the hat out-of-doors, and allowing the graceful lifting of the same at greeting and parting to express all the deference that the uncovered head is meant to symbolize.
