Obviously, their comfort and convenience should be prepared for and every possible help provided for them to understand and enjoy what is displayed. Plans for doing these things should be based on the expectation of as large an attendance as can be handled satisfactorily, and even on some overcrowding, unless small groups are deliberately sought. As is explained in the section on advance work, local committees should be appointed whose members will co-operate with the regular staff of the train. A reception committee may welcome special delegations and introduce them to the members of the train staff. If there is a formal program, local leaders are usually asked to take part in it, and as it is important in relation to the follow-up work that they have the opportunity to familiarize themselves with the subject matter and the methods demonstrated on the train, their presence throughout the day should be secured by advance arrangements. An added value in having them at the train is that in the eyes of visitors they will become identified with the movement and thus be in a better position to lead in the local follow-up work. Helpers are needed to look after the safety of the visitors, to form any waiting crowds into lines, direct people to the entrance, keep them moving in a single direction, prevent unnecessary congestion at any given point, and note questions and suggestions that should be passed on to members of the staff. If local volunteers are well prepared to perform these services the saving of strain on the hard-worked staff will be very great. THE RATE OF PROGRESS IN EXHIBIT CARS Reports show that managers of trains have been satisfied with both extremes in the rate of progress of visitors in moving through the train. One train director reported with pride that by his system he was able to “run 5,000 through in an hour.” At the other extreme are the directors who during their stay in a town give a single demonstration in a car that holds only about one hundred people. The method of “running people through” very rapidly is useful only if the exhibits are simply curiosities or objects of interest that may be quickly noted, and that we may risk having soon forgotten without loss to the cause that is being served. For example, the Liberty Loan trains depended chiefly on their program of talks, music, and the appearance of the returned soldiers to arouse interest. The large guns displayed on flat cars were visible while the talking was going on. It did not particularly matter after that whether visitors were passed through the trophy car so rapidly that they had only a glimpse of the various objects.
