The purchase of food in quantities by trained buyers would lift the grade of our supplies at once. No man is going to waste time and money in adulteration subject to daily analysis, or in offering stale, inferior articles which will not appear saleable to the trained eye. The wholesale poisoning of babies by bad milk is an evil our city governments are seeking to combat, but the helpless anarchy of a million ignorant homes, unorganised, untrained, and obliged to get the milk at once, renders our governmental efforts almost vain. Insufficient food is owing, in part, to economic causes, and in part to ignorance of what the body needs. On the economic side comes in a most important view of the home as a food purveyer. The private purchase and preparation of food is the most expensive method. It is wonderful to see how people cling to their notion of "the economy" of home-cooking. By the simplest business laws, of world-wide application, the small purchaser has to pay the largest price. The expenses incident to the re-retailing of food, from the apples rotting on the ground in New York State to the apples we purchase at twenty cents a quart for New York City tables, form a large part of the cost of living. Thousands of middlemen thrive like leeches on the long, slow current of food material, as it pours in myriad dribbling streams from the great sources of production, far away, into our innumerable kitchen doors. In a city block there are, let us say, two hundred families, which, at our usual average of five individuals to a family, would number one thousand persons. The thousand persons should consume, we will say, five hundred quarts of milk a day. The purchase of five hundred quarts of milk and the proportionate cream, as well as butter, would maintain a nice little dairy--several blocks together would maintain a large one. Your bustling restaurant proudly advertises "Milk and cream fresh every day from our own dairies!" But your beloved home has no such purchasing power, but meekly absorbs pale cultures of tuberculosis and typhoid fever at eight cents a quart. The poorer people are, the more they pay for food, separately. The organised purchasing power of these same people would double their food supply, and treble it.
