Various Causes.--Bad diet, the use of stimulating and exciting articles of food, late suppers, confectionery and dainties,--all these have a very powerful influence in the wrong direction by exciting functions which ought to be kept as nearly latent as possible. The use of tea and coffee by young ladies cannot be too strongly condemned. Improper dress, by causing local congestion, often predisposes to secret vice by occasioning local excitement. Probably a greater cause than any of those last mentioned is too great familiarity with the opposite sex. The silly letters which girls sometimes allow themselves to receive from the boys and young men of their acquaintance, and which they encourage by letters of a similar character, must be condemned in the most thorough manner. Upon receiving such a letter a pure-minded girl will consider herself insulted; and has just reason for so doing. The childish flirtations which girls and boys sometimes indulge in often lead to evils of a most revolting character. Modesty Woman's Safeguard.--True modesty and maidenly reserve are the best guardians of virtue. The girl who is truly modest, who encourages and allows no improper advances, need have no fear of annoyance from this source. She is equally safe from temptation to sin which may come to her in secret, when no human eye can behold. Maidenly modesty is one of the best qualities which any young lady can possess. A young woman who lacks modesty, who manifests boldness of manner and carelessness in deportment, is not only liable to have her virtue assailed by designing and unscrupulous men, but is herself likely to fall before the temptation to indulge in secret sin, which is certain to present itself in some way sooner or later. This invaluable protection is speedily lost by the girl who abandons herself to secret vice. The chances are very great, also, that by degrees her respect for and love of virtue and chastity will diminish until she is open to temptations to indulge in less secret sin; and thus she travels down the road of vice until she finds herself at last an inmate of a brothel or an outcast wanderer, rejected by friends, and lost to virtue, purity, and all that a true woman holds most dear. A Few Sad Cases.--Although we do not believe it right to harrow the feelings of those who have sinned and suffered with a rehearsal of sad cases when no good can be accomplished by such accounts, we deem it but just that those who are not yet entangled in the meshes of vice should have an opportunity of knowing the actual results of sin, and profiting by the sad experience of others. It is for this purpose that we shall mention a few cases which have come under our observation, taking care to avoid mentioning any facts which might lead to identification, as the facts we shall use were, many of them, received in strict confidence from those who were glad to unburden their hearts to some one, but had never dared to do so, even to their friends.
