The train consisted of a baggage car, two modern steel day coaches, each with a seating capacity of eighty-eight persons, which were used for lecture cars, and a private car, consisting of parlor and observation, dining and sleeping compartments. It was understood at the beginning that the train was to be an exclusive Hessian fly train and thus it was advertised as the Hessian Fly Special, operated by the Kansas State Agricultural College in co-operation with the Santa Fé. The speakers consisted of three entomologists of the Agricultural College, one entomologist of the United States Department of Agriculture, the head of the Department of Agronomy, the superintendent of Farmers’ Institutes of the college, and one county demonstration agent. In addition to the lecturers, the company consisted of the agricultural agent of the Santa Fé, the publicity agent of the Santa Fé, the publicity agent of the college, and representatives of some of the principal newspapers and farm publications. The divisional superintendents and roadmasters accompanied the train over their respective divisions of the road. Addresses were made at all of the sixty-two places scheduled. In fact, at nearly all the places the attendance was such as to require two speakers and, on several occasions, it required a third speaker to accommodate the large crowd. If the attendance did not exceed two hundred, the two speakers took care of them in the lecture cars, but where the crowd was over two hundred the over-flow was taken in the waiting room of the depot, where a speaker was provided. Where there was not an opportunity for the insect train to stop, a lecturer was dropped off to hold a meeting at the depot or an up-town place. Later, the man would be picked up by one of the regular trains and left at a station where the Hessian Fly Special was scheduled to stop. Or a man would be sent ahead on a regular train to hold a meeting and would later be picked up when the Special came through. In a few cases speakers were taken to neighboring towns in automobiles. During the entire trip every speaker on the train gave practically the same Hessian fly talk. The entomologists and the agronomist of the college prepared the speech, copies of which were furnished not only to the speakers but also to all the railroad officials and publicity men who accompanied the train. The publicity men prepared beforehand all the articles to be used by the newspapers in the places where addresses were made. In other words, every address given and every newspaper article published had just one message and that was the seriousness of the infestation and what should be done to protect the crop of the next year. It is the opinion of the writer that much of the success of the Hessian fly train and the good accomplished were due to the fact that all departments and all persons concerned were together,
