=Rehabilitation of the Competent.=--In the third place, for the one-half to one-third of criminal and habitually vicious left after the mentally incompetent are given proper care, we must use all the rehabilitation methods that society has devised and be more ingenious than we have yet been in adding to them. When such methods as Thomas Mott Osborne used fail, they generally fail because they are applied to those whom we should put under perpetual care, those indicated above as incompetent to life's demands. To try and make over a nature too weak in fibre to have anything of will or determination to "stitch to" is to have a response only when under constant supervision, and inevitable backslidings follow as soon as self-control is called for. It is true, however, that many who have gone far wrong make good and reach to a high attainment of character. They are the "occasional criminals," the "fallen" who met with extraordinary temptation, the too hardly used by fate, the too early exposed to evil influences, the wild natures too strictly curbed by mistaken methods of control, the orphans without parental love and guidance, the victims of broken family life, the "under-dogs" that could not make a way out to successful vocation or to happy human companionship. These occasional criminals among men, and the women or girls leading to sex temptations, may be often saved if so as by fire, and live to help all others to a stronger and better life than they have known. As this book is written the news comes of the death of such a woman in Chinatown of New York slums, a girl who had descended to the depths of vice but who came up at the call of the Salvation Army and spent the life left to her in helping others, such as she had once been, to hear and obey that call. Some men show such power of moral recovery as to put to shame those never tempted to a fall. These prove that mental power and the raw material of character, even after many untoward experiences, may take a fresh start and enable men and women to "rise on stepping-stones of their dead selves to higher things." =The Right Use of Leisure Time.=--In the fourth place, the agencies of social protection of child-life must cooeperate with all parents, whether those parents are wise or foolish, strong or weak, in preventing occasional criminality and preventable vice. The helpful use of leisure time is a vital factor in the prevention of vice and crime. The pioneer study of "Public Recreation Facilities" in the _Annals of the Academy of Political and Social Science_ of March, 1910, indicates lines of social service in this particular which have been followed to great social advantage.
