However attractively the subject is presented through motion pictures or other displays, a good talker is about the most important element in getting the idea across to the visitors. Whether the speaker accompanies his talk with slides or objects, conducts a demonstration, explains exhibits, or makes running comments on motion pictures, his ability to be heard, to hold interest, and to express himself simply, briefly, and concretely will often be the chief factor in the success of the program. Lecturers for traveling campaigns should be chosen as much for their ability as speakers as for their knowledge of the subject matter. PROGRAMS OF EXHIBIT TRAINS The following plan for a program was announced for one of the Liberty Loan trains: Aerial bombs will be sent off as train reaches stop. Liberty Loan representatives in charge of train will make brief address and ask local committee of three to come onto the platform. Five-minute address by the local chairman or someone selected by him. Talk by returned soldier. Address by experienced speaker with principal object of urging necessity of subscribing to Loan. Invitation by Liberty Loan representative to inspect exhibition. The trains for which this program was planned made short stops and the talks were given from a platform or from one of the flat cars. A large crowd could be reached by a single speaking program. In this case the speaking was the important feature, and the exhibits of war material were an “attraction” rather than an educational feature. It satisfied the purpose of the tour to have most of the time devoted to speeches, followed by a rapid view of exhibits. The extension division of the Texas State College of Agriculture reports the following program method: Immediately upon going into a town, the people were loaded into the lecture cars and three lecturers would alternate for a twenty-minute talk on different subjects in each car. Where outdoor meetings were held the exhibit cars were closed upon coming into town and general lectures were first had from the platform car, then the live stock were led onto the platform car where special demonstrations were given. As soon as this formal program was completed the specialists were stationed back through the exhibition cars and the crowds were allowed to enter the front of the train and pass gradually through the entire train, making such inquiries of the specialists as they cared to while going through the exhibition car.
