VI.—THE PRESENCE.

"The mode in which respect to the presence of a human being should be shown maybe left to custom. In the East, men take off their shoes before entering an apartment. We take off the hat, and add a verbal salutation. The mode is unimportant; it may vary with the humor of the moment; it may change with the changing fashion; but no one who respects himself, and has a proper regard for others, will omit to give some sign that he recognizes an essential difference between a horse and a man, between a stable and a house."[O]
