A further advantage that the indeterminate sentence has, is that it provides for a second period of probation. A man may behave himself well in prison but upon his release betake himself immediately to his old surroundings and then to his old habits. The most critical moment is when the prisoner steps outside the gaol walls and finds himself a free man. The habits of industry and good conduct acquired when in confinement have to be accommodated to new conditions, and if unassisted the task is often too great. The consequence is that he falls away and rejoins his old companions and soon becomes a recidivist. The indeterminate sentence allows for his freedom being regained gradually. Having given evidence of reform and of abilities to support himself, employment is found for him, and he is granted a parole. That is he is released conditionally. For the next half year he must report himself every month, and if at the end of that period he has behaved well he is granted absolute discharge. Opportunity is thus given for him to establish himself gradually amidst the conditions of free social life. The sense of freedom comes without shock, and when it comes, the critical period has long since passed away. Should he violate his parole in any way, he is rearrested and may be called upon to serve the maximum penalty for his crime. =The School of Letters.=--As has been said the system of the Reformatory is classified under the headings of mental, moral and manual. There is no sharp distinction between all three, inasmuch as no mental or manual training is considered of any value which does not also assist to develop the moral character of the pupil. The whole aim of the system is to develop minds and bodies, arrested in their growth, in order that they may become more susceptible to moral influences, and that habits of correct thinking and useful industry may be established. Every prisoner upon entering the institution is assigned to the school of letters, care being taken that the task imposed upon him is well within his mental grasp, but at the same time shall require an effort on his part in order to master it.
