The tours that are described in the following pages suggest just a few of the unusual and graphic features that may be assembled in a traveling show to attract attention and to make facts and ideas more easily understood and remembered. The train or truck in addition, as already suggested, to bringing into town especially talented or well-informed speakers and demonstrators, brings also equipment for demonstrations that may be bulky, expensive, or for other reasons difficult to duplicate and distribute for display; also rare objects such as the people in the communities visited would not be likely to see at all, except as they are brought in for this brief visit. THE TRAIN AS AN EVENT The visit of the train, like the revival meeting, the fair, or the Fourth of July celebration, may be made such a striking event in each community that its program gets and holds the attention of many people who would not read a newspaper article or go to an ordinary meeting to learn about the same topic. Such an event may be especially timely if a new movement or plan is about to be launched within the territory to be covered. The brief demonstration presented before a representative group of citizens gathered to meet the truck or train often paves the way for the organization of a permanent activity in the community. This is true because the method often allows for a more concentrated educational effort than can be effected in the same time through other types of campaigns. For example, the occasional visit of the agricultural special, demonstrating improved methods has, in many instances, preceded the forming of a county organization of farmers to devote themselves continuously to studying and experimenting in better farming. A train or truck campaign, well handled, will help to give freshness to ideas which may become stale if they continue to reach the people in the same familiar forms. Whatever the subject matter or purpose of a local movement for community education or welfare, both the workers or leaders and the people who form the audiences are refreshed by variations from familiar methods of presenting the ideas that need to be gone over time and again in order to get the greater numbers to listen, to understand, and to assimilate them. The local effectiveness of the work of the county agricultural agent, or the tuberculosis committee, or the movement for better rural schools may sometimes be stimulated through the visit of traveling campaigners bringing reinforcements in the way of enthusiasm, news gathered along the route, or old ideas illustrated in new and striking ways.
