A close third to tobacco and candy in the affections of the soldiers was chewing-gum. Three and a half million packages of the shop-girl’s delight were sent overseas during the month of January alone. Chewing-gum has come, indeed, to be regarded as little short of a necessity for the soldier, both because of its value as a substitute for water—it is estimated that 250 pounds of chewing-gum will save 100 gallons of water when it is needed most—and because it is a heat and energy producer. During intensive drilling, practice firing, and on marches the more gum a man chews the less water he drinks—obviously a highly important consideration, for at the front water is usually scarce and difficult to obtain. Curiously enough, the consumption of gum is heavier in winter than in summer, this doubtless being due, as I have already mentioned, to the fact that it is a heat-producer. It took the British, oddly enough, to devise a novel and interesting use for chewing-gum which was later adopted by certain of our own commanders. Just before an attack, when the assaulting battalions were formed up on the tapes waiting for the word which would send them over the top, the enemy’s scouts, prowling in No Man’s Land, frequently detected the presence of the waiting troops by their subdued chorus of coughing. A British officer who had been in the United States evolved the idea of stopping these betraying coughs by giving every man a stick of chewing-gum. So Messrs. Wrigley, Beeman, White, and Adams may congratulate themselves on having “done their bit” toward walloping the Hun.
