How Insects Affect Health in Rural Districts. Dept. of Agriculture. Bulletin 155. Public Health and Water Pollution. Bulletin 93. CHAPTER XIII BEAUTY America has another resource that differs from all the others, and yet is no less valuable to us as a nation, for it is upon natural beauty that we must depend to attract visitors and settlers from other countries, and also to develop love of country in our own people, and to arouse in them all the higher sentiments and ideals. The love of romance and poetry is awakened only by the sight of beautiful objects, and that nation will produce the highest class of citizens which has most within it to kindle these lofty ideas. The savage cares only for the comfort of his body, but as civilization advances, man devotes more and more thought to those pleasures that come only through his mind and the cultivation of his tastes. The United States is particularly fortunate in this respect, for here is everything to inspire a love of beauty. There is the beauty of changing seasons, of our wonderful autumn forest coloring, of rivers, mountains, lakes, sea, and shore. In addition to the beauty of our landscapes, which is everywhere to be found, there are many special beauties which are among the world's wonder-places, and which are visited yearly by thousands of sight-seers, and each year they attract a greater number of visitors from other lands. Some of the most remarkable of these are Niagara Falls, the Yosemite Valley, with its crowning glory, the Yosemite Falls, the Hetch-Hetchy Falls, Mammoth Cave, the Garden of the Gods, the Grand Canon of the Colorado, the Agatized Forests of Arizona, Yellowstone Park, The Natural Bridge of Virginia, Great Salt Lake, and dozens of others, less wonderful, but scarcely less beautiful, and equal to the most talked-of beauties of Europe, such as the Palisades of the Hudson, Lake Champlain, the Shenandoah Valley, the Dalles of Oregon, Pike's Peak, Mount Rainier, Lookout Mountain, the Adirondacks, and the entire Rocky Mountain region. To these must be added the relics of ancient civilization, the homes of the Cliff Dwellers, the work of the Mound Builders, and such fragments as still remain of the occupation in various times and places of certain Indian tribes, and of the Norsemen and the Spaniards. All these are to be valued for their beauty or historic interest, and are also valuable as a source of wealth to the community. The money spent on tourist-travel in Europe is said to be more than half a billion dollars a year. This vast amount is spent because in Europe there is so much to delight the eye, because the cities are made beautiful with artistic buildings filled with art treasures, because historic places are carefully preserved, because the villages are neat and well-kept, and the intensive farming which is practised almost everywhere leaves no waste places to grow up with weeds, and lie neglected.
