HERCULES POWDER CO. Backing The Fighter Back of our fighting man in France stands the mechanic who labors in our factories and munition plants. Back of the mechanic stands the miner whose broad back bends to his task in the dark heart of some -. . mountain. And back of the miner stands the power of explosives, /;. . loosening the grip of Mother Earth . on her wealth of metals and ., , minerals. Without the gigantic force of ex- !- . plosives it would be utterly impos sible for us to produce in sufficient quantities the munitions to supply : Sour armies over there; the steel to build our battleships; the coal whose latent energy turns the -s - wheels of our great manufacturing plants; the copper which goes to make our dynamos, cables, and shell casings; the gold which helps . us carry the great financial burden of the war.
