Along with this tendency went the attempt to give the pupil some first-hand knowledge of and immediate experience with the materials, implements, and products of the various industries from among which he or she might be expected to choose after leaving the school. This has been a difficult step to bring about, partly because of the various technical and administrative difficulties which it involved. Occasional hasty visits to mills, factories, stores, shops, offices, laboratories, and similar busy places give the pupil but a superficial notion of the actual work of the operations there observed. More extended and intensive observation, on the other hand, with perhaps an actual trial at the work, means a corresponding limitation of the range of institutions inspected. Talks by managers and foremen are likely to give only a dramatized view of the facts. School industries, on the other hand, cannot easily be organized and conducted in a manner technically complete and industrially representative. The result has been a growing tendency to push the vocational training further and further back into the earlier years of the curriculum, thus displacing much of the purely formal subject-matter. With this change have come various experiments in study-practice methods, in which part of the day or term is spent at the general academic work, and part in actual service in a tentatively chosen form of industrial or commercial activity. In this movement but little recognition was given to the psychological differences and peculiarities of the individuals concerned. Knowledge of personal aptitudes and capacities, interests, and satisfactions, was more or less taken for granted in each case, or at least left to develop in its own way. It was assumed either that any individual could satisfactorily pursue any vocation in which he might become interested, or else that industrial and vocational information alone was needed in order to enable the individual to make a suitable choice. Nor was there any doubt that the work which the youth found interesting and attractive at the time was the work in which he might find a maximum of ultimate success, satisfaction, and serviceableness. With the vocational surveys, the industrial schools, and the part-time practice methods of education we shall not be concerned, in what is to follow. They represent a movement of tremendous social and educational significance, but their development does not immediately concern that other field of work which we have designated "vocational psychology." They proceed mainly by giving the individual a knowledge of the external series of facts and events, thus replacing the era of fortune-telling and clairvoyance, with its search for signs and omens, just as fortune-telling had, in its own day, replaced the practices of crude objective magic. But the methods of industrial and occupational training have been found to solve only one aspect of the vocational problem; and it
