If the school experience is educational, the interest of the pupils in subject matter will not end with the solution of their shop problems or with their experience in industry. The above outline of tentative school subjects representing as they do the solution of the problems of a specific industry signifies merely the starting point of an adventure for young people in the serious affairs of adult life. There will be a large margin for choice in the election of subjects in which individual children will care to specialize but these subjects will be related more or less directly to the industry. The pupils will doubtless be freer in the second year than in the first to choose where they want to specialize as they will have had time in which to establish their ground work. But the election of studies in a two years' half-time course will not admit of flights very far afield of the subject in hand and of the problems originally set up. Those children who find that their participation in a productive enterprise is an enriching experience may elect to follow some special leads in science, in the past and present history of manufacture and commerce, in economics, in literature or in art. The intention of the school is to open up opportunities for such expansive expressions of the concrete experience as time and the capacity of the pupils admit, provided that the expression has its valid relation to the promotion or the enrichment of the enterprise of which they are responsible members. Certain pupils, we will say, will elect to carry further than others the testing of fuel, of heating and ventilating. Others may be concerned with experiments in power. A subject possibly will become of such absorbing interest to a pupil that he will want to experiment with the one he elects for its own sake and without relation to the problems in the shop. His interest may carry him into pure science, unattached to any problem in hand. In such cases the pupil should be given a chance to test out his interest; he should be placed on probation in relation to his elected subject and if his interest holds and is sufficiently serious he will be advised to give up the school-shop work and follow the lead his interest has taken in some other place or school.
