The Department of Science and Research of the Council of National Defense did particularly valuable work in getting together the scientific and technical men of the country and so organizing and directing their knowledge and skill and their ability in research as to form a war resource of inestimable value. Its membership included a large part of the men representative of the scientific, technical and engineering achievement in the United States and through this Department of the Council their services were at the call of the Government whenever needed. Through its General Medical Board the Council aided in the mobilization of the medical personnel and resources of the country. Its Committee on Engineering and Education brought together the best thought and skill for the solution of engineering problems in connection with the war and for the aligning of educational institutions and facilities behind the country’s war effort. Its Committee on Labor, besides drafting the war-risk insurance bill and initiating that undertaking and aiding in the development of the plan for the War Labor Administration, did valuable work in helping to maintain hearty coöperation between the labor movement and the national war policies by promoting the welfare of industrial workers and by providing a system for the rapid and intensive training of mechanics. Its Highways Transport Committee coöperated with the War Department in facilitating the work of its important motor-truck convoy service, developed rural motor express routes, instituted a movement for the better development and care of highways and assisted the Railroad Administration in its early struggle with the congestion of freight.
