Where does all the paper go? To the lay mind this question appears impossible of a comprehensive answer. He concedes that the publishing and commercial worlds, from the magnitude of their operations, must absorb colossal quantities, but this reflection does not bring complete comfort. During the war period it was not so difficult to reduce the apparent enigma to simple explanation. The Stationery Office devoured paper to the extent of 57,000 tons a year. The Ministry of Munitions absorbed 1,000 tons a week in the actual manufacture of missiles, one use being the substitution of aluminium by paper for filling the tips of bullets, while fuse cylinders were also contrived from paper instead of from tin. The Ministry of Food called for 400 to 500 tons of paper to provide the cards for sugar, meat and butter rations, while the issuance of the subsequent ration books ran away with another 750 tons. The War Office was probably the heaviest consumer, from the simple fact that all jams and preserves issued to the army, and packed in one-pound consignments, were served in paper cartons instead of tins. Seeing that the quantities of jams issued in this manner ran into millions, the consumption of paper for the containers was stupendous. Such zealous and ingenious recourse to paper instead of metals for such purposes was readily explicable. For instance, at the time, tin was costing about £320--$1,600--per ton as compared with brown paper at £35--$175--and cardboard at £50--$250--per ton respectively. It was to the advantage of the nation to abandon costly metals whenever and wherever a paper substitute was equally serviceable. To counteract the shortage in supplies from abroad every effort was made to extend and to develop the domestic manufacturing facilities. This was not such a simple task as it appeared, inasmuch as we are sadly lacking in the reserves of the necessary material. We possess no soft-wood forests waiting to be turned into paper. In these circumstances the alternative was to embark upon a voyage of discovery and experiment in the hope that an efficient inexpensive range of substitutes might be unearthed to take the place of the imported wood-pulp, either exclusively, which was scarcely to be expected, or to a very pronounced degree.
