Now began a notable campaign of education which was carried straight into the kitchen. Food demonstrators whose work ranged from showing the economy of cooking potatoes in their skins to making fire-less cookers out of a soap box and a bundle of straw, went up and down the Kingdom holding classes. In town halls, schools, village centres and drawing-rooms, mistress and maid sat side by side. "Waste nothing," was the new watchword. Backing up the uttered word was a perfect deluge of literature that included "Hand Books for House Wives," "Notes on Cooking," "Hints for Saving Fuel," "Economy in Food," in fact, dozens of pamphlets all showing how to make one scrap of food or a single stick of wood do the work of two. The people behind this movement knew that with waste of food was the kindred waste of money. They realised, too, that even the most effective preachment for food economy must inevitably be met by the cry, "Everybody must eat." With money, on the other hand, there seemed a better opportunity to drive home a permanent thrift lesson. So the forces that had built the bulwark around the English stomach now set to work to rear a rampart about the English pocketbook. Circumstances played into their hand. The Great War Loan of $3,000,000,000 had just been authorised. "Why not make this loan the text of a great National thrift lesson and give every working man and woman a chance to become a financial partner of the Empire," said the saving mentors. It was decided to put part of this loan within the range of everybody, that is, to issue it in denominations from five shilling scrip pieces up, to sell it through the post office and thus bring the new savings bank to the very doors of the people. Again a machine was needed, and once more as in the case of the food campaign one was well oiled and accessible. It was the organisation that had raised, by eloquent word and equally stimulating poster and pamphlet, the great volunteer army of 3,000,000 men. Just as it had drawn soldiers to the fighting colours, so did it now seek to lure the savings of the people to the financial standard of the nation. The Parliamentary Recruiting Committee became the Parliamentary War Savings Committee and it loosed a campaign of exploitation such as England had never seen before. From newspapers, bill boards and rostrums was hurled the injunction to buy the War Loan and help mould the Silver Bullet that would crush the Germans. It was literally a "popular loan" in that the five shilling short-term vouchers, bought at the post office, and which paid 5 per cent, could be exchanged when they had grown to five pounds for a share of long-term War Stock paying 41/2 per cent. The higher rate of interest was the inducement to begin saving and it worked like a charm.
