be confused and made unpractical by conflicting theories. The Bible, the great instrument in the education of conscience, is far less juvenile than it is now the fashion to suppose. At the very least, it expresses the result of the ripest human experience, the noblest traditions of humanity. Old Testament history, even more than most very ancient history, is distilled to an almost purely ethical content. For centuries Scripture was withheld from the masses for the same reason that Plato refused at first to put his thoughts into writing, because it would be sure to be misunderstood by very many and lead to that worst of errors and fanaticism caused by half-truths. Children should not approach it too lightly. The Old Testament, perhaps before or more than the New, is the Bible for childhood. A good, protracted course of the law pedagogically prepares the way for the apprehension of the Gospel. Then the study of the Old Testament should begin with selected tales, told, as in the German schools, impressively, in the teacher's language, but objectively, and without exegetical or hortatory comment. The appeal is directly to the understanding only at first, but the moral lesson is brought clearly and surely within the child's reach, but not personally applied after the manner common with us. Probably the most important changes for the educator to study are those which begin between the ages of twelve and sixteen and are completed only some years later, when the young adolescent receives from nature a new capital of energy and altruistic feeling. It is physiological second birth, and success in life depends upon the care and wisdom with which this new and final invoice of energy is husbanded. These changes constitute a natural predisposition to a change of heart, and may perhaps be called, in Kantian phrase, its _schema_. Even from the psychophysic standpoint it is a correct instinct which has slowly led churches to center so much of their cultus upon regeneration. In this I, of course, only assert here the neurophysical side, which is everywhere present, even if everywhere subordinate to the spiritual side. As everywhere, so here, too, the physical may be called in a sense regulative rather than constitutive. It is therefore not surprising that statistics show that far more conversions, proportionately, take place during the adolescent period, which does not normally end before the age of twenty-four or five, than during any other period of equal length. At this age most churches confirm.
