Shade trees and shrubbery too close and dense around a house are unhealthy; for they prevent a free circulation of air, and prevent the rays of the sun from shining sufficiently through. In consequence of this, a dampness gathers in the house. Especially in wet seasons the sleeping rooms become damp, and those who sleep in the beds are troubled with rheumatism, neuralgia, and lung complaints, which generally end in consumption. Numerous shade trees cast off many leaves, which, if not immediately removed, decay, and poison the atmosphere. A yard beautified with scattering trees, and some shrubbery, at a proper distance from the house, has a happy, cheerful influence upon the family, and, if well taken care of, will prove no injury to health. Dwellings, if possible, should be built upon high and dry ground. If a house be built where water settles around it, remaining for a time, and then drying away, a poisonous miasma arises, and fever and ague, sore throat, lung diseases, and fevers will be the result.
