3. _The kitchen and the Dust Heap.--Removal of Household Refuse_.--It has to be assumed, especially where servants are not carefully overlooked, that the dust heap of most houses will contain more or less decomposing organic matter, such as bits of meat, scales and refuse of fish, tea and coffee grounds, and the peelings of vegetables, which, though quite out of place in the ash heap, are apt surreptitiously to be thrown upon it. Such matter soon becomes offensive and even dangerous, and a few days' retention of it in warm weather constitutes a legal nuisance. Household refuse should be carted away as often as once in two days; in extreme hot weather, daily. Where it is inexpedient to remove it frequently, it should be kept covered to the depth of two or three inches with a layer of powdered charcoal, or freshly burnt lime, or, at least, of clear dry earth. All soil which has become foul by the soakage of decaying or vegetable matter should be similarly treated. The refuse heap should be protected from rain, and liquids should never be thrown upon it. Where obnoxious matter has been allowed to accumulate, its disturbance for removal should be conducted with special precaution, both on account of its temporary offensiveness of odor and the more serious results which may follow. It can not be too distinctly understood that cleanliness, ventilation, and dryness are the best of all deodorizers. One of the first of household regulations should be to see that no unsanitary rubbish remains in or about the dwelling. Keep the dust heap itself at the farthest practicable remove from the house. Sow grass seed plentifully upon the back premises, and induce tidiness in the domestics by having the kitchen door open upon a well-kept lawn. _Burning of Garbage_.--The easiest, quickest, and most sanitary method of disposing of household garbage is to burn it This plan has been officially recommended by the Boards of Health in various cities. Many housekeepers have adopted it, and find it so practicable that in New York City there has become a marked decrease in the amount of household refuse collected by the scavengers. If, after every meal, the draughts of the range be opened, and all waste matter be deposited within, a few moments, or at most, a half hour, will effectually dispose of it, and prevent all the dangers that arise from its retention and accumulation. In the country, where there is plenty of ground, nearly all rubbish can be destroyed in this way and by outside fires, with the additional advantage that the--E. R. S.
