The Instructor in Vice.--Are these lines perused by any one who has ever taught another this vice so vile, and so certainly followed by penalties so terrible--penalties not upon the instigator but upon the hapless victim? let such a person clothe himself in sackcloth and ashes, and do penance for the remainder of his life. The only way in which he can hope to atone even in some small degree for such a heinous crime, is by doing all in his power to warn those in danger against this sin. When all men receive their just deserts, what will be the punishment of such a one who has not, by thorough repentance and a life spent in trying to undo the work of ruin so foully wrought, in some measure disburdened himself of the consequences of his act! Sending children very early to bed before they are weary, "to get them out of the way," or for punishment, is a grave error, as this may give rise to the vice. Confining children alone in a room by themselves is an equally reprehensible practice, as it favors the commission of the act, at least, and may afford a favorable opportunity for its discovery. Allowing children to form a habit of seeking solitude is an evil of the same nature. Local Disease.--In the male, a tight or long foreskin is a frequent cause of the habit. The constant contact of the prepuce with the most sensitive part of the organ increases its sensibility. The secretion is retained, and accumulates, often becoming hardened. In this manner irritation is set up, which occasions uncomfortable feelings, and attracts the hands to the part. Owing to the great degree of excitement due to irritation, but a slight provocation is necessary to arouse voluptuous sensations, and then the terrible secret is revealed. The child readily discovers how to reproduce the same, and is not slow to commit a frequent repetition of the act; and thus the habit is formed.
