We see, on turning to Prof. Arnold's "American Dairying," that he says: "The temperature of a curing-room for whole milk should be 65 to 70 degrees; for part skims, 75 to 80 degrees." It is thus seen that fat plays an important part in curing. "The more fat," he says, "the cooler may be the room; and the less fat, the warmer may it be." Again: "Under the present state of things, a cheese that will stand a voyage of 4,000 miles can hardly be called a fancy cheese. * * * But a much fancier cheese than we are now producing, one that will stand shipping, can be made. To do this will require milk to be free from some of the imperfections which are now quite common; it must be transported to the factories in much better ventilated cans; _it must be made with less rennet and less acidity; and it must be cured in an even and lower temperature_." We mark the conclusion in _italics_, because we believe these are vital points. We insist that we cannot do ourselves credit nor realize the best financial results in cheese making until we build better curing rooms--rooms in which we can control the temperature without fail. We have not yet settled down to cheese making. We are still trying experiments and resorting to temporary expedients. We must build far more deliberately and for permanency. It is not necessary that we should point out just how a building may be erected so as to give control of the inside temperature. Architects know how to do it. When our cheese makers get to the point where they demand such buildings, they will get them without much trouble and at moderate expense. It is only necessary that they should have the "will." The "way" will speedily open. WHEY. We notice that, in some localities, the patrons of the cheese factory are very much interested in the question of the value of whey for feeding purposes--some going so far as to assert that what is left of milk in cheese making is as valuable as what is removed! This is a startling assertion, and, if true, would convict our dairymen of a vast amount of stupid waste. Is it true? Let us try to get at the facts of the case by a direct, common-sense investigation of it. COMPOSITION OF MILK. We will begin with the composition of milk. From hundreds of German analyses, ranging from 81.30 to 91.50 parts of water, we take a fair average analysis, which we think will do justice to the mixed milk of our best cheese factories: Water 87.18 Caseine 4.21 Albumen .55 Fat 3.24 Sugar 4.21 Ash .60 ----- Total 99.99 WHAT IS TAKEN OUT BY CHEESE MAKING.
