As much of this region is arid or semi-arid, precipitation being largely confined to snowfall on the higher eleva- tions, agriculture and every other form of civilized life is dependent upon artificial irrigation. The water for these works must be derived principally from the snows accumulating on the higher moun- tain slopes, and the forests covering the steep sides are of the greatest importance in protecting the irrigation works. Without them the floods at the time of melting snows and after... heavy showers in summer would rush down with such impetuosity that the dams, basins, and canals could not with- stand their force. The erosion of the mountain sides would be so great that the valleys together with the irrigation works would be quickly filled up with gravel, silt, and mud. The United States, which still holds most of the land in this region, 172 North American Forests and Forestry- has seen the absolute necessity of preserving the mountain forests and has recently set aside a num- ber of large forest tracts in various parts of the mountain regions, to be preserved as protective forests.
