THE VESTIBULE SCHOOL 283 in the shop itself and given over exclusively to the task of training incoming employees. Each of these methods has certain advantages and disadvantages. The first method has all the advantages consequent upon physical concentration. The centralized school makes it possible for one expert personnel worker to su- peivise the training of all novices, and thereby removes the diversities and inconsistencies which are sure to arise under a decentralized scheme. Second, it facilitates the process of trying novices out on different types of work in the event of their initial failure. Third, it serves as a kind of reservoir or safety valve by which to regulate the excess of workers in some shops and the shortage in ocher shops. Fourth, it acts as a reclaiming station to which old em ployees who have failed or outgrown their work can be sent for new instructions and encouragement. This method has its disadvantages as well. They appear in an analysis of the advantages of the decentral ized school. Under the latter scheme, the applicant, after having been tested and selected for a certain type of work, is at once sent to the shop in which this work is being carried on. There, at machines or benches reserved for that particular purpose, the applicant is immediately instructed in the exact work for which he is intended. The advantages of this method are as follows: First, the proximity of the pupil to the actual work of the shop en ables him to see at once what his environment and work are to be. If this environment and work are unsatisfac tory, the pupil will know it quickly, whereas if he is coached in a central school, at some distance from the shop and under slightly or considerably different condi tions, and then dislikes the shop to which he is sent, all the time spent on preliminary training becomes lost effort.
