=Motor Service.= In order to reach the people of outlying districts, it is possible to organize a girls’ motor service. Have the automobiles go to an advertised point where they will pick up all who desire to go to the train. They can make several trips in morning and afternoon. It would be well to have automobiles doing this work carry banners advertising the train and its special work. VI THE MESSAGE OF THE TOUR The message of the campaign includes the ideas, facts, and plans to be presented to the audiences. The choice of a topic or its scope, what to say about it, and how much, are questions deserving more thoughtful consideration and real work than is usually given to them. The most important and the most difficult thing in preparing the message is to have constantly in mind a picture of the way in which it is to be delivered. If, for example, the project takes the form of an exhibit and lecture train in which visitors will spend part of their time listening to a talk and the remainder passing through several cars to examine displays, we should, as we plan the message, try to picture the train on the siding at, let us say, Jonesville. We should also visualize the numbers and types of people likely to come, how they will divide their time between the talks and the exhibits, how long they will stay, or how long we will wish them to stay, what they know about the subject already, and what they will want to know, what they could do with this or that kind of information, and how much and what part of the message they are likely to remember. If the campaign is carried on with a truck and its program includes a demonstration which only a few people can see, and a motion picture and lecture program for much larger numbers, there are two problems; first, visualizing the small groups for the demonstration, and second, the larger audience for the more popular program. Reports of topics and methods of presenting them that have come in from many and varied traveling campaigns indicate that much more attention could be given to this question of preparing the message, and that frequently topics have been selected and the form of presentation worked out with only a very hazy visualization of the conditions and the people to be encountered at Jonesville and other points along the route. CHOICE OF A TOPIC Experience leads most directors, sooner or later, to choose a single topic that is definite and concrete, rather than a group of topics or one that is broad in scope. This limiting of the topic is all the more likely to be important where the subject of the campaign is unfamiliar to the prospective audience. The titles given to many of the agricultural trains indicate that their directors have found the concrete and single topic satisfactory. Trains have been called the “Stump Pulling Special,” “Wheat Special,” “Better Seed Car,” and “Dairy Train.”
