The religious opinions, especially of those from whom we are receiving hospitality, must on no account be shocked, scoffed at, or in any way treated with a want of respect. If our friends go regularly to church, we should accompany them there; or, without remark, repair to the place of worship most agreeable to our own religious convictions. If family prayers are read, we should endeavor to be present. If silent grace is the custom at meal times, our heads must also bow, and a short mental prayer be said. If the Sunday is observed with great strictness, we should refrain from any pursuits to which objection could possibly be made, even if they appear to ourselves perfectly proper and innocent. In short, we must remember that for the time the feelings and prejudices of the host and hostess are our own. There is no occasion when it is more necessary to remember that social intercourse is made up of innumerable little acts of kindness, self-denial, charity, chivalry, and good-fellowship, than when a number of people find themselves thrown together for companionship in the house of some mutual friend. Letters delivered in the presence of the host or hostess, or when the other guests are present, must not be opened until the receiver asks permission to read them. A lady may never offer to pay any of the expenses incurred by taking her about--carriage hire, steamboat fares, or such outlay nor must a gentleman do so unless he is the only gentleman of the party. It will then be well for the hostess, before starting, to hand him the necessary tickets previously purchased. When a guest is ready to leave you, be sure that the trunks are strapped and ticketed, a carriage ready in good season, a luncheon prepared for refreshment upon the journey, a substantial meal ready in good season for comfortable enjoyment of it, and the departure made as pleasant as possible. "Welcome the coming, speed the parting guest." It is the first duty of the guest, after returning home, to write to the host or hostess, expressing the pleasure derived from the visit, and mentioning each member of the family by name, desiring to be remembered to all. STREET ETIQUETTE. WHEN a gentleman recognizes a friend in the course of his walk, he must lift his hat with the hand farthest from him. Lifting the hat is a sufficient recognition between gentlemen; but in meeting a lady, an old gentleman, or a clergyman, it is necessary to bow also. If a gentleman wishes to shake hands with a friend, he must lift his hat with the left hand, leaving the right free to extend. Never must he give his left hand, or extend a portion of the right. The whole right hand is _en regle_. A lady must recognize a gentleman, by bowing, before he is at liberty to acknowledge an acquaintance with her. Should she bow, he must lift his hat and bow also. If he is sufficiently barbarous to have a cigar in his mouth, he must remove it while bowing to a lady.
