and that nothing was said or done but what met with the approval and recommendation of every one. The fact that the very methods advocated for the control of the fly were in keeping with the very methods recommended by the Agronomy Department and which the progressive and successful wheat growers knew should be practiced for maximum yields, appealed to the better judgment of even the most skeptical ones. The time allowed for each stop was about forty minutes. The speakers usually arranged for a few minutes’ discussion before closing the meeting. Specimen cases, charts, and illustrated material were used in nearly all lectures. As the men left the lecture cars or the waiting room they were given circulars on the Hessian fly and the preparation of the seed bed for wheat. The Hessian fly circular was printed primarily for the occasion. It was simply a timely article emphasizing the methods of control and closing with a brief life history of the fly. In nearly all cases large crowds met the Hessian Fly Special and the total attendance for the week was approximately seven thousand.[3] HEALTH TRAINS In the early days of the tuberculosis movement cars were extensively used in traveling health campaigns. A pioneer in carrying the message of health over a state on exhibit trains was Dr. Oscar Dowling, President of the Louisiana State Board of Health. His health train made its initial trip in 1910 and with many changes since that time has continued in service. After the first tours, made with cars loaned by the railroad, had demonstrated the popularity of the train, the State Board of Health purchased two coaches. One was fitted up as an inspection car with a part of it given over to living and office quarters, and the other as an educational exhibit car, containing displays of models, charts, and laboratory specimens. Later, two more cars were purchased for living quarters and the inspection car was turned into a laboratory car. A practical application of the lessons taught on the tour was made by inspectors who accompanied the train. In each place visited they inspected and scored buildings in which the sanitary conditions imperilled public health, the reports of their findings being given publicity while the train was in town. This train attracted the attention of health workers in other states and has made a number of trips outside of Louisiana in response to their requests.
