What bread is for the adult milk is for the baby. It, too, was zonified. The milk-line disappeared. A card similar to that governing the distribution of bread was adopted, and dealers were responsible for the quantities assigned them. The time which mothers had formerly wasted standing in line could now be given to the care of the household, and baby was benefited not a little by that.
Simple and effective as these measures were, they could not be extended to every branch of distribution. In the consumption of bread, milk, and fats known quantities could be dealt with. What the supply on hand was could be more or less accurately established, and the ration issued was the very minimum in all cases. Waste from needless consumption was out of the question.
It was different in other lines. The governments wanted to save as much food as was possible, and this could best be done by means of the food-line. The line had boosted prices into the unreasonable for the profiteer, but was now used by the several governments to limit consumption to the strictly necessary. To issue potatoes and other foods in given quantities was well enough, but not all that could be done. In some cases half a pound of potatoes per capita each day was too little; in others it was too much, though taken by and large it was a safe average ration. The same was true of cooking-flour and other foods. Those able to buy meat and fish stood in no need of what the government had to allow those who could not include these things in their bill of fare. On the other hand, it was impossible to divide consumers into classes and allow one class a quarter of a pound and another half a pound of potatoes each day. That would have led to confusion and waste.
A scheme of equalization that would leave unneeded food in the control of the government became necessary. The food-line provided that in a thorough manner. The woman not needing food supplies on a certain day was not likely to stand in a food-line, especially when the weather was bad. She would do with what she had, so long as she knew that when her supply was exhausted she could get more. The cards she had would not be good next week, so that she was unable to demand what otherwise would have been an arrear. The green card was good for nothing during a week of red cards. Nor was there anything to be gained by keeping the green card in the hope that some time green cards would again be issued and honored. By the time all the color shades were exhausted the government changed the shape of the card and later printed on its head the number of the week.
