Here again the speaking and the outdoor demonstrations are evidently regarded as the important features. Such a plan should not be considered if the exhibits are of real importance. The audience that has been standing during the program of perhaps half an hour or more, and has then waited in line to go through the train, is a tired audience and not nearly so responsive as though its members came fresh to the exhibits. It is also true that when the program is so arranged that the whole crowd is ready at one time to start through the train, there is much more difficulty in managing the people and much more dissatisfaction on the part of those at the rear end of the line. It is difficult to get careful attention for exhibits from people who are being moved ahead to make way for an impatient crowd standing in long lines behind them. The managers of trains will do well to decide in advance whether the speaking or the exhibits constitute the really important feature of the program. If it is the exhibits, then the speaking should be made incidental, perhaps, by having a ten-minute talk given from the platform at regular intervals as a new group is to be started through the train. A PROGRAM COMBINING DEMONSTRATIONS AND EXHIBITS A method of dividing the time between demonstrations in two cars and an exhibit car was worked out satisfactorily on the Pennsylvania Food Conservation Train. All the audience passed through the train in the same direction, starting at the same point, except that at the beginning of the session all the cars were filled at once to avoid delays. When the first car was filled a talk on canning started. No attempt was made to demonstrate a complete process, but different vegetables or fruits were in various stages of preparation continuously, so that a fifteen-minute illustrated talk brought out the points that required emphasis. After about five minutes of questions and looking at displays of equipment and canned articles, this crowd moved on to the next car, while the first car was filled again with the next group of arrivals. In the second car a similar program was given on uses of wheat substitutes. In the third car two explainers met the audience and explained the exhibits found there. As the topics in all three cars were closely related (the demonstrations showing how to save food and the exhibits showing why food saving was necessary), an hour spent in three cars gave variety enough to keep interest awake and still kept closely to the one big idea--“Save Food.” [Illustration: DEMONSTRATION CAR A day coach used for a canning demonstration on the food conservation train of the New York Central Railroad and the New York State College of Agriculture.] [Illustration: AN OUTDOOR PROGRAM Crowd listening to a speech at the War Trophy Train which toured Kentucky as a feature of the Fourth Liberty Loan campaign.] OUTDOOR SPEAKING AT TRAINS
