One great fault in building houses in both city and country, is to make them too low on the ground. There should be distance enough to allow a free circulation of air, say three feet, between the floor and the earth. All rubbish, shavings, etc., should be cleaned away before siding up, and a good ventilation should be kept open to insure dry, sweet air under the floors. Much sickness is caused to many families from low underpinning, and close, damp, stagnant air, carrying miasma into the lower rooms, through the floors of dwellings. Many houses are built upon flat ground, and the earth thrown around the outside, making a sink under the house to hold water. This is wrong, It is much better to raise the ground under the house, and even gravel and cement before building. At any rate, ventilation under the house should always be attended to. We do not believe in cellars under the house in this climate, but whenever there is a cellar it should be open, and always kept clean of decaying substances. Guard against the enemies to health that lurk under a house.—Ex.
