Whom to Avoid.--A girl will always do well to avoid a companion who is vain, idle, silly, or frivolous. Girls who have these evil characteristics are very likely to have others also which are worse. A girl who is rude in her manners, careless in her habits, irreverent and disobedient to parents and teachers, is always an unsafe companion. No matter how pretty, witty, stylish, or aristocratic she may be, she should be shunned. Her influence will be withering, debasing, wherever felt. A girl may be gay and thoughtless without being vicious; but the chances are ten to one that she will become sinful unless she changes her ways. Sentimental Books.--The majority of girls love to read, but, unfortunately, the kind of literature of which they are chiefly fond is not of a character which will elevate, refine, or in any way benefit them. Story books, romances, love tales, and religious novels constitute the chief part of the reading matter which American young ladies greedily devour. We have known young ladies still in their teens who had read whole libraries of the most exciting novels. The taste for novel-reading is like that for liquor or opium. It is never satiated. It grows with gratification. A confirmed novel-reader is almost as difficult to reform as a confirmed inebriate or opium-eater. The influence upon the mind is most damaging and pernicious. It not only destroys the love for solid, useful reading, but excites the emotions, and in many cases keeps the passions in a perfect fever of excitement. The confessions of young women who were to all appearance the most circumspect in every particular, and whom no one mistrusted to be capable of vile thoughts, have convinced us that this evil is more prevalent than many, even of those who are quite well informed, would be willing to admit. By reading of this kind, many are led to resort to self-abuse for the gratification of passions which over-stimulation has made almost uncontrollable. Some have thus been induced to sin who had never been injured by other influences, but discovered the fatal secret themselves. Mothers cannot be too careful of the character of the books which their daughters read. Every book, magazine, and paper should be carefully scrutinized, unless its character is already well known, before it is allowed to be read. In our opinion, some of the literature which passes as standard, which is often found on parlor center-tables and in family and school libraries, such as Chaucer's poems, and other writings of a kindred character, is unfit for perusal by inexperienced and unsophisticated young ladies. Some of this literature is actually too vile for any one to read, and if written to-day by any poet of note would cause his works to be committed to the stove and the rag-bag in spite of his reputation.
