©Albert Schlechten THE FOOD OF TO-MORROW FLOATS IN THE SKIES OF TO-DAY The Solomons overlooked this proverb, but the science of meteorology is ready to write it. The world hasitslife-sustaining circulation ofmoisture much as the body has its essential circulation of blood. The water that rises from the sea as vapor,condenses asclouds, and falls asrain makes the world's crops for man and beast before it starts again for the skies, on another cycle. The clouds arean ever-redeemed promise ofourdaily bread. The smaller clouds near the horizon are fracto-cumuli (broken cumuli) ; the formation near the upper edge ofthephotograph iscirro-stratus.
