Show Iiiftt JicHtritrtor. A corresjiondeiit asks, What is tho "dust destructor?" Tho dust destructor it a group of furnaces set in an inclosed (space containing the requisite yards and buildings used for consuming the rubbish rub-bish which is swept oil the London streets, which amounts to many thousands thou-sands of tuns in a year. Tho furnace honse is approached by an incline driveway drive-way leading to a covered place above the furnaces. In this place the scavengers' scaven-gers' carts shoot their rubbish, which by simple apparatus is dropped into the furnaces, where it is 8jeedi:y converted into "clinker." This clinker is then removed re-moved and broken np. Some of it is ground, some reground, aud some ground a third time. Iu the ward are seen piles of broken and ground clinker, some of course lumps, some resembling gravel, some looking like the finest and. For all this material there is a use. Some of it goes to form the foundation of roads; some, mixed with tar, is made into a durable pavement; some makes admirable admira-ble sand for mortar and cement, aud some is made into imitation stone for. sidewalks. Ia tho Battersea district of London the parish wagon houses, stables, blacksmith shops, etc., have been constructed entirely of this imitation imita-tion stono made from the refuse of domestic do-mestic dust bins and the streets. If any of the residents of tho parish want any of tho broken or ground clinker fur any purpose they aro permitted per-mitted to take as much of it as they can carry away iu harrows or carts. Nothing Noth-ing goes to waste. Tho process of cremation cre-mation is c heap, and this method of disposing dis-posing of the refuse of a crowded district dis-trict has hud a wholesome effect from a fanitary point of view. In Battersea tho death rate has gone down from eighteen to eleven. New York Commercial Com-mercial Advertiser. - - |
