Drainage For Health

Fiom tlie Sanifarmn. Tbe proper drainage of buildings is a matter of great iuiportünoe. Cellargrruay be wet, stit)lt not very dry, water nmy drip from the oh ves, cuttiug hulinto the earth and niaking puddles. The wntar from Buch puddles filters direotly into the collar, so that oíd houses in the country are vcry frequently dangfiious to lite on account of tho water settling into the oellara. A damp cellar muy gometlmes be mude dry by inaking a sink in it, as already desoribed for the flelds. Ceflurs are sometimo made in such wrutcliod placos that thcy need drain-pipes to uurry off the watrr. In arranging any of Uu's kind of work about a stable do not filter into any water required for domestic use. Water should on no account be allojft'ed to drip from the eaves ; it is a gre.-it nui8anco, underiuining foundations uud rapidly dettroying buiidinga. Air oonfined anywhere, even in a clean room, become8 offensivo, probnbly unhealthy, with dieagreeable smell of oloseness, andconfined with filth in a drain or se wer, it rauet be mnnitely vvorse. Drains built tigbt, with traps, ete., so that thero is no ventilation of their interior, genérate very poisonous gases, whioh aro re&dy on the occurrenco oí any small leak to escape and poiaon everybody who happens to go near thern. The beat arrangement for ventilators in houses is to have a separate flue built in the chimney-sWck expressly to receive the ventilator pipes. - Th us the air from the drain is diacharged high in tho atmosphere in a position to he mixed withsmoke; and tho noxious prop orties are destroyed, the smoke, wtiether of wood or coal, containingabout thu bast chemioal diainfectant known. In all parta of New England hundreds of people are dying every year of typhoid fever; a large tract of the city of Boston is uow building on made land, nearly as flat as the prairies about Chicago ; aiid in a few years it will doubtleas have to be regraded and rebuilt to get rid of thib pestUer.ce. From Maine to Pennsylvania there are flat, undrained fields, and wet cellars ueurly as bad. All ovor the country furlher south, but pnncipally in the Mississippi Valley and the flat country bordering the ocean, the hali-drained land is iufected with iuterniittent fefer and the other malarial pestilences to puch an extent as to destroy many thousands of people every year ; so that, in spite of constant irurnigration, extensive tracts of country are about as sparsely peopled as they were when Pocahontas saved the life of John Smith.
