"When the habit and its effects are of very short duration, a cure is very readily accomplished, especially in the cases of children and females, as in them the evils begun are not continued in the form of involuntary pollutions. In cases of longer standing in males, the take is more difficult, but still the prospect of recovery is very favorable, provided the cooperation of the patient can be secured ; without this, little can be done. But in those cases the patient may as well be told at the outset that the task of undoing the evil works of years of sin is no easy matter. It can only be accomplished by determined effort, by steady perseverance in right doing, and in the application of necessary remedies. Those who have long practiced the vice, or long suffered severely from its effects, have received an injury which will inevitably be life-long to a greater or lesser extent in spite of all that can be done for them. Yet such need not despair, for they may receive inestimable benefit by the prevention of greater damage, which they are sure to suffer if the disease is allowed to go unchecked."
