Of recent years many peddlers, carrying new ideas and useful information but no goods for sale, have been going about the country representing national and state government bureaus and private organizations. Their wares are helps to better crops, better houses, better health. Their mode of traveling has progressed from wagons to trains and from trains to motor trucks. The size of the enterprise has varied from a single wagon or automobile with a speaker and a batch of leaflets to a train of railroad cars or trucks that carry a traveling exhibit rivaling the “Greatest Show on Earth.” The tours extend from a jaunt through the county or the districts of a city to a transcontinental journey. Whatever its form, if the purpose of the enterprise is to spread information or ideas, or to promote a community program, it is of interest from an educational and publicity standpoint.
