Such a cool-bath is used in the cow-room only in summer, when the heat is so great that it is difficult to keep the milk cool in the kitchen. The cool-bath in the cow-room is considered as only an auxiliary to that in the kitchen, and to be used only in case of necessity. The milk-kettles are hung by their handles, and let down by means of a crank. When the platform is not in use it is taken away from the cool-bath, and the cover is let down and kept closed. The milk is allowed to remain in the cool-bath until the froth has disappeared, and there is no difference in temperature between the water and the milk. The milk of one milking must give place for the next, so that it will be changed twice daily, morning and evening. A very great importance is, everywhere in the Dutch dairies, attached to this rapid cooling of the milk, because it is known by experience that it is thus greatly protected from turning sour.[3] [3] It will be perceived that the arrangement for cooling the milk before setting in the pans, in the Dutch dairies, is very elaborate. I have followed the original in translating the above, though the practice in Holland differs widely from our own in this respect, and from that recommended in the preceding pages. The point may be worthy of careful experiment.--TRANSLATOR. The milk, when properly cooled, is brought to the milk-cellar, where it is immediately poured out of the milk-kettles into vessels designed to receive it. Wooden bowls or pans, or high earthen pots, are used for holding it. The pans and pots are set on the table, and a small ladder, or hand-barrow, is laid on there, on which is placed the strainer, when the milk is poured from the kettles. The wooden milk-pans are of several forms, generally made of ash or of linden, and oval. They are, on an average, three and a half feet long, and half a foot broad, more or less; but their dimensions vary. It has been found, by experience, that the flatter and shallower the pans, the quicker and better the cream rises. The milk-pots are pretty large, but are rather shallow than deep, glazed inside, of different forms, and different capacities; but they are always broader on the top than at the bottom, though they stand firmly on a round, broad foot-piece. Milk pans and pots are rinsed with cold water before the milk is poured into them. When properly cleaned and filled, they are placed on shelves made for the purpose, in regular rows. These shelves are only a few feet high above the floor of the cellar, and of suitable width; but, if there is not space enough for the milk, the pans are placed on the bottom of the cellar. The pots are also set along the walls, on firm board shelves.
