The _Dairy_ should have thick walls, and a brick or stone floor, so contrived that it may be washed with abundance of water every day, and yet have all the water run off by means of a waste-pipe or drain. There should be a kind of shelf of stone or slate round it, about four feet from the ground, and a table of similar materials in the centre, for the convenience of holding the vessels containing the milk and cream; and the window, if there is but one, should look towards the north, and be filled in with wire-cloth, so as to admit the air and yet exclude the flies and other insects. Besides this wirework, the window should also have either a sash frame with ground glass to open inside, or outside shutters, to exclude the sun in very hot weather, and the cold in winter. A thermometer should be kept in every dairy, and the heat should never be allowed to rise above 55°, or to fall below 50°. There should always be a scullery attached to the dairy containing a fireplace and boiler, as the vessels in which milk is kept require to be frequently washed with scalding-hot water to keep the milk sweet, and to prevent the butter and cream from acquiring an unpleasant taste. Though I do not imagine your knowledge of a dairy to be very great, I suppose you are aware that the milk is drawn from the cow into a can or wooden pail, and brought into the dairy, where it is strained, and then put into shallow vessels or milk-pans, in which it is left for several hours in order that the cream may rise. Cows are generally milked twice a day; the morning's milk being skimmed in the afternoon, when the afternoon's milk is put into pans, or set up as the dairy-maids call it, and the afternoon's milk being skimmed in the morning. The cream, after what is wanted for the table has been taken out, is put into a large wide-mouthed jar or stein, and saved for butter. Cheese is generally made of new milk, which is put at once into the cheese-tub without setting it up in pans. The cheese-tub and cheese-press, the churn and all the apparatus for making butter, generally stand in the dairy scullery, where the operations of cheese and butter making are carried on.
