SCHOOL HYGIENE
Priests have to put up buildings for parochial schools, colleges, seminaries, orphan asylums, convents, and the like, but in such work sanitation is commonly given only a passing thought in connection with sewer-traps and these are left to the wisdom of a plumber. The physical welfare of youth is almost as important as its mental training, and there are many factors beside sewer-traps involved in the effort to sustain it.
If there is freedom of choice as regards the site of a schoolhouse or similar building, the top of a small elevation is to be selected. Such a position affords the best natural drainage, removes dampness, avoids inundations, gives full sunlight and the purer air. The top of a high hill may be too exposed to the wind.
Next to the top of a knoll, the southerly slope of a hill is to be chosen. The building should not be overshadowed by a hill, especially on the western side. Trees are not to be planted close to a building in which children live, and ivy and similar plants should not be permitted to cover the walls.
If a building is set in a hollow it will be surrounded with chill air and mists in the cold seasons, even if a costly drainage system keeps the cellar and basement dry.
A gravelly or sandy soil beneath a building is the best, provided this soil is not already saturated with organic matter, or is not close above a dense layer of clay or rock. Clay, marl, peat, and made soils should be avoided if possible, because they are full of organic matter; they are cold, and they infect the ground air. Rock does not make a good building site—its seams carry water.
The subsoil should be drained four or six feet below the cellar floor, and this floor is to be laid in concrete and cement. At the level of the ground there should be a course of hollow vitrified brick to exclude dampness and to give ventilation.
