Only the aggregate price which the retailer gets for all parts and portions of the carcass will show his margin over the initial cost. It is wholly improper, therefore, to compare sixty-cent steaks with twelve-cent cattle with a view to determining profit. The same thing is true of hogs and of sheep. A hog is not all meat, nor is the meat all ham. A sheep is not all carcass and only a small part of the carcass cuts up into chops. One must know the aggregate return and something about the costs of doing business before a justifiable conclusion as to price margins can be determined. THE BUSINESS OF BEING A HOUSEWIFE THE home managers have in their hands the most important business of the nation. American women realize that to their duties as home makers, mothers, and guiding influences, is added an important economic responsibility. The manner in which the purchasing power of twenty million home managers is used has an inestimable effect upon the production, collection, and distribution of all products in the market. This second edition of “The Business of Being a Housewife” is respectfully dedicated to the thousands of wise home managers who are determined to understand more fully their relation to the producers of the country and to the great industries, such as that of Armour and Company, who have made possible the providing of perfect food in perfect condition at any distance from the farm. ECONOMIC CHANGES A study of the national and world situation on food production shows that old-time low food prices may never return. Formerly much of the food was raised by numerous individual families on Government land at nominal cost; today practically all food is raised on expensive land—the plains have been turned into villages and farms by the increasing population. Many men and expensive machinery and equipment are needed to produce our present high standard products. It became economically unsound for so great a percentage of food producers to spend their time in producing meats and staples, only part of which could be consumed by themselves and their near neighbors, the rest going to waste. The great waste of the surplus products set the minds of men of genius to devising ways to preserve the foods of abundant harvests for the seasons of scarcity. The result is before us in the form of modern cold-storage plants, refrigerator cars, volume-curing and pickling of meat products, and volume-canning of fish, meats, fruits, and vegetables; great cereal factories, etc.
