The time has not yet come when man may plow the atmosphere for rains as he plows the soil for crops. If mines must be worked and towns built in arid regions, let promoters of these schemes be required to build aqueducts and bore wells sufficient in advance to supply the needed water, not waiting until droughts come and the people die. Every place on this globe has its rainy years and its dry years. Areas of cold and heat, wind and calm, rain and drought, appear and move and disappear in irregular succession. We must prepare for them and provide against disaster. We can not control the weather, but we may control ourselves.
