Regulation of Explosives in the United States: with Especial Reference to the Administration of the Explosives Act of October 6, 1917, by the Bureau of Mines

From Origin of Federal Explosives Act, October 6, 1917: " A competent force from the Bureau of Mines was then assigned to study the laws and ordinances of countries, States, and municipalities in which lawas and ordinances regulating explosives have been enacted, and especially to ascertain how these laws had been modified by the necessities of the existing state of war, and, also, wherein the proposed law might conflict with or overlap the jurisdiction of existing laws. This incomplete enumeration of the peace-time uses of explosives shows that the quantity consumed is large. A more definite conception is given by the following statistics of production, to which is added statistics for exportation that disclose something of the effect of war on the explosives industry."
