How may the impression made by the program and exhibits of the train be fixed in the minds of its visitors promptly, so that forgetting may be delayed until results are obtained? Several simple methods suggest themselves. We will take up here mainly those things that can be done while the train is in town or soon after its departure, as we are concerned only with the part that the train tour plays in the whole program of the organization that sends it out. GETTING THE SUBJECT TALKED ABOUT If the visitors talk about what they saw and heard they are likely to remember it much longer and more accurately than if they do not. The principles discussed elsewhere, of simplicity of form, concentration on one main topic, orderly arrangement, and lack of crowding in both exhibits and programs, have a definite application to getting the subject talked about. People speak vaguely and in general terms about what they have not clearly understood. We may imagine that A, who saw the train, meets B, who did not, and the following conversation takes place: A: Did you see the health train yesterday? B: No, how was it? A: Oh, fine! great! You certainly missed it. There was a good crowd out, too. B: What was it all about? A: Oh, fresh air and not letting the babies die. You’d be surprised how many people die that could be prevented. And they say the town ought to have a nurse to look after the school children, and a hospital for--let’s see, I’ve forgotten now about the hospital. B: I see. Just a scheme of the politicians to make jobs for a lot of people. I always thought this was a pretty healthy town and I do yet. A: No, you’ve got it wrong, B, but I can’t make it clear to you. I can’t talk like the fellow at the train. You ought to have heard him. He made a great speech. If A has no clearer idea than this to pass on to B the next day, he himself is not likely to stay interested and, much less, convinced for very long. One of the best tests of the argument presented at the train is whether the talk about it afterward is general or particular, confused or clear and accurate in repeating facts and reasons. It is worth while to arrange with local co-operators as a part of the follow-up work to sound people as to what interested them and what they think of the suggestions that were made. Many changes, sometimes small ones, but important, nevertheless, can be made on the basis of criticisms brought out in these interviews. PRINTED MATTER FOR DISTRIBUTION
