To the making of the Modified Enfield rifle go 84 parts and a total of 164 pieces. These parts were all standardized so that any of those made in either of the three large plants that manufactured this rifle could be used in any other. This made possible the rapid rate at which they were turned out. Rigorous tests for each part and close inspection of every process, together with the enthusiastic interest of the employees, made the number of rejected rifles negligible. The employees of one concern, of their own inspiration and desire, adopted the slogan of “one million rifles for 1918” after they had subscribed $1,000,000 to the third Liberty Loan. This plant, which had under roof more than thirty-three acres, was built in 1915 to manufacture rifles for the British Government, but soon after our entrance into the war signed a contract with the United States. It speeded production so rapidly that by mid-summer of 1918 it was two months in advance of its expected production. Automatic pistols proved of so much value at the front that General Pershing, as soon as the American troops had got well into the fighting, asked for the supply to be quadrupled and at once numerous private plants began to manufacture them. One firm that had been steadily turning out automatics at the rate of 1,500 per day prepared to double its capacity when the front line needs were made known. Of these and revolvers there had been sent to the front 600,000 up to the end of September, 1918. Of small arms ammunition, including that for machine guns, rifles, pistols and revolvers, American factories produced a total of about three billion rounds. Monthly production had reached a rate of 289,000,000 rounds. The armor piercing, tracer and incendiary bullets used in the Aircraft Service and in anti-aircraft defense were developments of the war and had to be designed for our own guns and to have special facilities for their production. For the loading of shells four huge government plants were constructed with a combined loading capacity of more than 5,000,000 shells per month. They were larger than any similar plants in the world. One of them covered nearly 3,000 acres and was built and put into operation, from the breaking of the ground, in a little more than six months. For the housing of its employees a town was brought into existence, within that time, with heating, lighting and power plants, police and fire departments, cottages for families, dormitories with hot and cold shower baths for single men, club-houses, a theater, restaurants, a baseball field and tennis courts. Of high explosive shells of all sizes there had been made, at the end of September, 1918, 2,500,000; of low explosive shells, 3,100,000; of shrapnel, 5,800,000; and of grenades of all types 11,870,000. One grenade factory had established a pace of a million per month.
