This is in perfect accord with the chiropractic philosophy as to the expression of life in the body. The building site may be so unnatural as to create an environment which would draw too heavily upon the adaptative forces of the body. In this case Innate would find difficulty in maintaining a state of coördination. [Illustration: Model Site] The artificial methods of living must be made to conform as nearly as possible to the needs of the body. Damp surroundings might have no ill effects upon the individual who was living a very active life outdoors “roughing it,” but place that individual in a damp, poorly lighted and poorly heated house where he is less active and his expression of life will be materially affected. Innate requires a proper environment, although not necessarily a perfect one, but it must be such that an adaptation can be maintained. [Illustration: Unsanitary building site.] If the building site is damp it will require special methods to prevent the dampness from entering the house. This is expensive and if the site is too humid such a method will prove highly unsatisfactory. If the location is cold the house is very likely to be cold. The site should be well adapted to the needs of the building. Aspect The importance of the aspect should not be overlooked. A southeasterly facing is generally considered best, because it is dry and mild and has the morning sun and yet is not exposed to the hot afternoon sun.
