The _fourth_ agency, which has been very largely developed recently, but which has always been used, is the agency of work. This has been applied in approximately three ways. The first of these is known as diversional occupation and comprises practically the whole field of what is thought of by many as occupational therapy. The activities in this field consist of such work as basket weaving, leather tooling, bead stringing, rug weaving, and a thousand other similar activities. The object of this activity is to assist in the re-direction of the patient’s interests, to turn them away from infantile and regressive objects, and to project them again into the outer world of reality. Then there is the industrial type of work therapy in which the patient is carried still further along the line of personal initiative and given an opportunity to do creative work which is at the same time useful and which helps him to keep in form pending the time of his ultimate discharge from the hospital. And finally, there is the vocational education work, which undertakes definitely and systematically to give a man training in some specific direction which he can utilize, after he leaves the institution, and which will have a definite economic value. For this latter work of vocational training there is needed such psychological advice and assistance which will at least prevent the wastage of time and effort upon unprofitable or impossible tasks, whereas the vocational psychologist cannot by any rule-of-thumb-tests tell that a man will make a success in this or that direction, he can tell within reasonable limits that a certain patient cannot profitably undertake a certain type of training, that his capacities do not measure up to the minimum requirements that would make success possible. In this way the work of vocational education for the neuropsychiatric case can be narrowed down so that it can be applied more intensively and more effectively to selected groups that can be reasonably assumed to be good risks. The _fifth_ agency, which can be advantageously brought to bear upon the neuropsychiatric case, is the agency for extra-mural social adjustment, and the personnel consists of the psychiatric social worker. With her help the patient discharged from the hospital can have the maximum amount of assistance for relating him again with the problem of self-support and self-sufficiency. She, through her study of his family situation, his economic status, his industrial placement and social contacts can assist to these ends.
