Finally on the matter of follow-up work, one of the chief criticisms that may be made of much educational publicity is that it is spasmodic and unrelated. This is often due to the fact that the planning of follow-up work is left until the campaign is at its height or until it is over. By that time the workers at headquarters and in the field are too absorbed in the detail of running the affair, or a new project is under way. All the resources and energy have gone into running the campaign and none is left for securing results. In the advance planning of the whole campaign, allowance should be made in the budget for a definite program of follow-up work as well as in the time of staff members needed to carry it out.

APPENDIX REFERENCE LISTS OF TRAIN, TRUCK, TROLLEY, AND OTHER TRAVELING CAMPAIGNS The lists below include traveling educational campaigns about which we have obtained reasonably accurate information. The two chief sources of further information about these projects are the state colleges of agriculture and state boards of health. Very little information about tours is available in published form. Articles in class publications giving brief accounts of a few of the tours and a few special reports about tours are listed in Appendix B. In practically all the train tours, one or more railroads have co-operated at least to the extent of supplying cars and free transportation, and sometimes bearing a considerable share of the work and expenses of the tour. Our lists, we realize, do not always give the full credit to co-operating railroads and other participants, but as much is given as it was possible to ascertain and to indicate within the space limits. We are aware, also, that the list is by no means a complete record of educational tours. Information is coming in continually about tours that we had not known of before. The main purpose, however, is to give a general idea of the purposes, forms, and extent of traveling campaigns in recent years, together with only a few of such details as may help the inquirer decide where to look further for suggestions that may be of assistance in his particular case. The list does not include tours of trucks or trains for service only, as, for example, library trucks or laboratory trains. Neither does it include “chapel cars,” that is, railroad cars, motor vehicles, and boats, for religious services or instruction, such as have been sent out by various religious bodies for many years.
