    ASH CLOSET. The dry closet which approaches nearest to the best form of midden closet is the one in which ash is used as the deodoriser. This is described in a paper read before the Manchester and Salford Sanitary Asso- ciation by Mr. Morell, of which an extract is given by the Rivers Pollution Commissioners, 1868 {First Report, vol. ii. p. 309). Each closet is provided with Mecimn- an ash-sifter, which is brought into motion by the opening of the door, the fine ash falling through into a storing measurer, fixed in the back wall. The seat of the closet is covered by a lid, which, when opened or shut, measures out into the excrement receptacle (an easily movable water-tight vessel) a quantity of ash sufiicient to deodorise its contents. The cinders which do not pass through the sifter are of course used again as fuel. It is stated that whenever there street is not sufficient ash-dust to be had, as perhaps may u^nsed.^^ sometimes be the case in summer, it is easy to supplement it by throwing on to the screener some fine street sweepings. For stories above the ground Plan for floor it is proposed to have a wide tube brought down abor to or below the ground floor, and opening into a receptacle placed there, which might be removed when full, or as occasion required. A circular vessel, 2 feet deep and 1 foot 9 inches in diameter, will con- tain the ash and excrement refuse from one house with five occupants for twenty days. Removal once a week, or once each fortnight, for such a house, will therefore be sufficiently frequent. Mr. Taylor has patented a dry closet of much the same kind as the separation above, but in which the urine is not allowed to remain with the soil and ashes, but escapes from the soil-pan G
