Cases Illustrating the Effects of Self-Abuse.--The land is full of poor human wrecks who have dashed in pieces their hopes for this world, and too often for the next also, against this hideous rock which lies hidden in the pathway of every young man who starts out upon life's stormy voyage. Gladly would we draw the veil and cover them with all their dreadful deformities with the mantle of charity from the gaze of their fellow-beings; but their number is so great that this could scarcely be done, and the lesson to be learned from their sad fate is such a grave one, and so needful for the good of the generation of young men who are just encountering the same dangers, that we cannot resist the promptings of duty to present a few examples of the effects of vice in men and boys that have fallen under our own observation. We have seen hundreds of cases of this sort; have treated many scores of persons for the effects of the terrible crime which we are seeking to sound a warning against, and the number of cases we might describe would fill a volume; but we will select only a very few. Two Young Wrecks.--Charles and Oscar B---- were the sons of a farmer in a Western State, aged respectively ten and twelve years. They possessed well-formed heads, and once had beautiful faces, and were as bright and sprightly as any little boys of their age to be found anywhere. Their father was proud of them, and their fond mother took great pleasure in building bright prospects for her darling sons when they should attain maturity and become competent to fill useful and honorable positions in the world. Living in a rapidly-growing Western community, they had every prospect of growing up to honorable usefulness, a comfort to their parents, a blessing to the world, and capable of enjoying life in the highest degree. But suddenly certain manifestations appeared which gave rise to grave apprehensions on the part of the parents. It was observed that the elder of the little boys no longer played about with that nimbleness which he had formerly shown, but seemed slow and stiff in his movements. Sometimes, indeed, he would stagger a little when he walked. Soon, also, his speech became affected in some degree; he mumbled his words and could not speak distinctly. In spite of all that could be done, the disease continued, increasing slowly in all its symptoms from week to week. Soon the hands, also, became affected, so that the little boy could not feed himself. The mind now began to fail. The bright eyes became vacant and expressionless. Instead of the merry light which used to shine in them, there was a blank, idiotic stare. Imagine the grief and anguish of the poor mother! No one but a mother who has been called to pass through a similar trial could know how to sympathize with such a one. Her darling son she saw daily becoming a prey to a strange, incurable malady, with no power even to stay the progress of the terrible disease.
