having
arrived at intimacy, may commence with "Dear Sir," and end with "I am,
dear Sir, yours very truly."

Letters commencing "My dear Sir," addressed to persons whom you
appreciate, and with whom you are on friendly terms, may end with "I
am, my dear Sir, yours very faithfully," or "yours very sincerely."

To be prompt in replying to a letter is to be polite.

VI.--THE PROMENADE.

A well-bred man must entertain no respect for the brim of his hat. "A
bow," says La Fontaine, "is a note drawn at sight." You are bound
to acknowledge it immediately, and to the full amount. The two most
elegant men of their day, Charles the Second and George the Fourth,
never failed to take off their hats to the meanest of their subjects.
Always bear this example in mind; and remember that to nod, or merely
to touch the brim of the hat, is far from courteous. True politeness
demands that the hat should be quite lifted from the head.

On meeting friends with whom you are likely to shake hands, remove
your hat with the left hand in order to leave the right hand free.

If you meet a lady in the street whom you are sufficiently intimate
to address, do not stop her, but turn round and walk beside her in
whichever direction she is going. When you have said all that you wish
to say, you can take your leave.

If you meet a lady with whom you are not particularly well acquainted,
wait for her recognition before you venture to bow to her.

In bowing to a lady whom you are not going to address, lift your hat
with that hand which is farthest from her. For instance, if you pass
her on the right side, use your left hand; if on the left, use your
right.

If you are on horseback and wish to converse with a lady who is on
foot, you must dismount and lead your horse, so as not to give her the
fatigue of looking up to your level. Neither should you subject her
to the impropriety of carrying on a conversation in a tone necessarily
louder than is sanctioned in public by the laws of good breeding.

When you meet friends or acquaintances in the streets, the
exhibitions, or any public places, take care not to pronounce their
names so loudly as to attract the attention of the passers-by. Never
call across the street: and never carry on a dialogue in a public
vehicle, unless your interlocutor occupies the seat beside your own.

In walking with a lady, take charge of any small parcel, parasol, or
book with wh
