It is too little appreciated that every natural object makes a twofold appeal to the human mind: its appeal in the terms of its physical or material uses, and its appeal to our sense of beauty and of personal satisfaction. As the people progresses in evolution, the public mind becomes constantly more sensitive to the conditions in which we live, and the appeal to the spiritual satisfaction of life constantly becomes stronger. Not only shall the physical needs of life be met, but the earth will constantly be made a more satisfactory place in which to live. We must not only save our forests in order that they may yield timber and conserve our water supplies, but also that they may adorn and dominate the landscape and contribute to the meaning of scenery. It is important that our coal supplies be conserved not only for their use in manufacture and the arts, but also that smoke does not vitiate the atmosphere and render it unhealthful, and discolor the objects in the landscape. It is of the greatest importance that water supplies be conserved by storage reservoirs and other means, but this conservation should be accomplished in such a way as not to menace health or offend the eye or destroy the beauty of contiguous landscape. The impounding of waters without regard to preserving natural water-falls, streams, and other scenery, is a mark of a commercial and selfish age, and is a procedure that cannot be tolerated in a highly developed society. It is important that regulations be enacted regarding the operation of steam roads through woody districts, not only that the timber may be saved, but also that the natural beauty of the landscape may be protected from fire and other forms of destruction. The fertility of the soil must be saved, not only that products may be raised with which to feed and clothe the people, but also that the beauty of thrifty and productive farms may be saved to the landscape. The property-right in natural scenery is a tenure of the people, and the best conservation of natural resources is impossible until this fact is recognized.
