Although traveling campaigns have been many and varied and the method has been in use for a number of years, to our knowledge there has been no attempt up to this time to set down the methods and experiences, the successes, failures, and difficulties of the various campaigners. Believing that this method of promoting social programs will continue to be employed, whatever the type of vehicle used to convey travelers and their outfits, we have gathered information about a number of campaigns and offer it here, together with comments and suggestions for the benefit of those who may be considering the method for the first time or who have tried it and wish to compare their experiences with those of others. The descriptions and suggestions are drawn from accounts of about seventy-five tours of trains, trucks, trolley cars, and other vehicles, obtained from printed reports, articles, letters, replies to questionnaires and interviews, as well as from the observations and experience of the writer. II PURPOSES AND ADVANTAGES OF TRAVELING CAMPAIGNS The popular educational tour on wheels is a method of carrying news and facts from town to town, instead of distributing this information in wholesale manner to many towns at the same time through newspapers, letters, posters, and other familiar avenues for disseminating information quickly and widely. This use of a method resembling more or less the old-time place-to-place spreading of the news but in a modern, up-to-the-minute dress, even under the most favorable conditions involves a considerable outlay in money, a great deal of hard work, careful and detailed planning, and equally careful oversight throughout the journey and the follow-up period. Therefore the person or group contemplating such an undertaking will naturally wish to consider carefully its efficiency as a method of publicity before embarking on it. In some instances the reason for using the truck or train is that it may be routed to remote rural districts not well served by the more modern methods of news distribution. Wherever it goes, however, the train or truck has two chief advantages as a publicity method; first, it is an economical way of bringing before scattered audiences well-equipped speakers or graphic and otherwise attractive illustrative material--economical because a single group of speakers or unit of exhibits may in this way be made to serve a large territory; and, second, its visit to each town may be made an important event, something which creates news and which may appeal to the imagination of people generally.
