Excerpt from Illinois Mineral Industry in 1941 All of these increases in mineral production and processing during 1941 were due directly or indirectly to the tremendous program of military prepara tions carried on by the United States at a constantly increasing rate throughout the year. The second World War began to affect the mineral industry of Illinois during 1940 by the stimulation of demand from industries directly connected with filling orders for military equipment for this country and for foreign countries. This stimulation continued and increased throughout 1941 from the rapidly increasing military preparations of the United States and the great program of aiding its allies, which culminated in the United States entering the war in December, 1941.
