Natural environments and tree fragrances offer restorative properties and relief to weary invalids.

Original passage

How grateful to the invalids weary of city life, the glare of many lights, and the noise of the streets, are the quiet and freedom of the country! How eagerly do they turn to the scenes of nature! How glad would they be to sit in the open air, rejoice in the sunshine, and breathe the fragrance of tree and flower! There are life-giving properties in the balsam of the pine, in the fragrance of the cedar and the fir, and other trees also have properties that are health restoring.
