A motion picture tour with an automobile truck, traveled for twenty-eight weeks in 1917 in Maryland at an expense of $124 a week. This included the fuel and repairs for the car, expenses of the field staff, rentals of films, and various miscellaneous expenses connected with the operation of the tour. III HOW TRAINS HAVE BEEN USED IN CAMPAIGNING For a number of years, with the co-operation of the railroads, state agricultural colleges, departments of health, and private state organizations have carried on educational and organization work through demonstration trains. The war propaganda which utilized practically every known form of publicity did not overlook train, truck or trolley. One or more of these was used in the campaigns for Liberty Loans, food conservation, and child welfare. Descriptions of a few of these trains will illustrate the varied types of campaigns in which they have been employed. AGRICULTURAL TRAINS A Peach Demonstration Train started on a tour in November, 1919, for the purpose of encouraging and stimulating the peach industry in the East Texas Fruit Belt. The train consisted of two baggage cars containing exhibits of insect pests that menace the peach industry, life-sized models of diseased and perfect fruit, and actual branches of affected peach trees, and a box car containing a tractor, orchard plows, and various other kinds of farm machinery needed by an up-to-date orchardist. Regarding this train Mr. P. T. Cole, Agricultural Commissioner, St. Louis Southwestern Railroad of Texas, writes as follows: The cars were moved on local freight trains nearly all the time, although on a few occasions we were moved by a through freight. The cars were opened to the public at 9 a.m., and the farmers were taken through in groups of about fifteen and a thorough lecture given them with explanations in detail regarding the various exhibits. We usually let the school children go through, but did not allow them to interfere with the work we were giving the farmers. In the afternoon, at about one o’clock, we accompanied the farmers to a nearby orchard taking with us pruning tools, the power sprayer, and the tractor. In the orchard we gave lectures on pruning, and then pruned about a dozen trees, or sometimes as many as fifty, after which we gave them a thorough spraying. This demonstration usually consumed the greater part of the afternoon, but we would return to the cars and discuss the different problems of orcharding with the growers and in many cases they remained with us until dark.
