Sunshine is the enemy of disease, which thrives in darkness and shadow.

Consumption or scrofulous disease is almost inevitable in the house shut in by trees, whose blinds are tightly closed lest some ray of sunshine fade the carpets; and over and over again it has been proved that the first conditions of health are, abundant supply of pure air, and free admission of sunlight to every nook and cranny.

Even with imperfect or improper food, these two allies are strong enough to carry the day for health; and, when the three work in harmony, the best life is at once assured.
If the house must be on the lowlands, seek a sandy or gravelly soil; and avoid those built over clay beds, or even where clay bottom is found under the sand or loam.

In the last case, if drainage is understood, pipes may be so arranged as to secure against any standing water; but, unless this is done, the clammy moisture on walls, and the chill in every closed room, are sufficient indication that the conditions for disease are ripe or ripening.

The only course in such case, after seeking proper drainage, is, first, abundant sunlight, and, second, open fires, which will act not only as drying agents, but as ventilators and purifiers.
