These may be kept perfectly clean with good care, and washing and scalding them well with salt and water. As soon as the operation of churning is performed, the butter should be washed immediately in several waters, till thoroughly cleansed from the milk, which should be forced out with a flat wooden ladle, or skimming dish, provided with a short handle. This should be quickly performed, with as little working of the butter as possible; for if it be too much beaten and turned, it will become tough and gluey, which greatly debases its quality. To beat it up with the hand is an indelicate practice, as the butter cannot fail to imbibe the animal effluvia: a warm hand especially will soften it, and make it appear greasy. If the heat of the weather should render it too soft to receive the impression of the mould, it may be put into small vessels, and allowed to swim in a trough of cold water, provided the butter do not come in contact with the water, which would diminish some of its best qualities. A little common salt must be worked up in the butter at the time of making it, and care must be taken not to handle it too much. Meat hung in a dairy will taint the air, and spoil the milk.--See BUTTER, CHEESE, CHURNING, &c. DAMP BEDS. Of all other means of taking cold, damp beds are the most dangerous, and persons who keep them in their houses are guilty of a species of murder, though it unfortunately happens that no housewife is willing to acknowledge that _her_ beds were ever damp. There is however no other effectual way of preventing the dreadful effects so often experienced in this way, than by keeping the beds in constant use, or causing them frequently to be slept in till they are wanted by a stranger. In inns, where the beds are used almost every night, nothing more is necessary than to keep the rooms well aired, and the linen quite dry. If a bed be suspected of dampness, introduce a glass goblet between the sheets with its bottom upwards, immediately after the warming pan is taken out. After a few minutes, if any moisture adheres to the inside of the glass, it is a certain sign that the bed is damp: but if only a slight steam appears, all is safe. If a goblet be not at hand, a looking glass will answer the purpose. The safest way in all such cases is to take off the sheets, and sleep between the blankets. DAMP HOUSES. Nothing is more common than for persons to hazard their lives by inhabiting a dwelling almost as soon as the plasterer or the painter has performed his work, and yet this ought to be guarded against with the utmost care. The custom of sitting in a room lately washed, and before it is thoroughly dried, is also highly injurious to health. Colds occasioned by these means often bring on asthmas and incurable consumptions.
