Castle 1948 9min sd (Soil conservation ser) $12.28 551.4 el-Jh-sh-tr Produced by the U.S. Dept. of Agriculture The story of water — its numerous values and its potential destructive power when uncontrolled. It develops the theme that water is essential to all life and that the most valuable water is that which soaks into the grround where it falls as rain or snow; while destructive water is that which is permitted to run off uncontrolled from the ground where it falls. It points out the disadvantages of both too much and too little rain and what we can do to remedy either situation thru soil and water conservation methods WATER CYCLE. EBF 1947 lOmin sd (General science ser) $45, rent $2.50 551.4 el-jh-ad Guide Collaborator: S. Ralph Powers, Teachers College, Columbia University Shows the movements of water from ocean to sky to rain to streams, rivers and back to oceans. The motion picture describes by actual photography and animation how the circulation of water is divided into atmospheric and ground circulation, how clouds form, how storms develop, how droplets of water collect and how rain falls, and follows the movements of surface and underground water WORK OF RIVERS. EBF 1935 llmin sd (General science ser) $45, rent $2.50 551.4 jh-sh-c Guide By Carey Corneis, University of Chicago The erosion cycle of water on the earth's surface. The cycle of a river from its very beginning to old age. Models and animated cartoons are employed to explain such special features as Niagara Falls, deltas, meanders, ox-bow lakes, rejuvenated rivers, lakes, water gaps, and sand bars WORK OF RUNNING WATER, EBF 1931 llmin sd (Earth sciences ser) $45, rent $2.50 551.4 Jh-sh-c Guide Made with the cooperation of Harvard University Film Service "The greatest force in wearing away of the land is that of running water. Models and scenes from all parts of the world show how running water wears away the land. Many picturesque evidences of erosion are analyzed. "An unusually complete sequence on the formation of deltas and flood plains, splendidly Illustrated by aerial pictures of the Mississippi bottom lands, and sand table models. The way in which rivers straighten their courses and how great canyons are formed are also clearly shown." Harvard 55 1 .5 Meteorology AEROLOGY— AIR MASSES AND FRONTS.

Points out the weather problems in flight operation in warm and cold front occlusion MODERN WEATHER THEORY: DEVELOP^ * MENT AND CHARACTERISTICS OF ATMOSPHERIC WAVES. Castle 1943 15min sd $20.68 551.5 jh-sh-c-tr-ad Produced by the U.S. Army Air Forces "Animation and maps, combined with commentary, explaining the principles of the development and characteristics of atmospheric waves."

Castle 1943 19min sd $24.99 551.5 jh-sh-c-tr-ad Produced by the U.S. Army Air Forces "By means of animation and maps we are shown weather under normal conditions and the atmosphere that creates the prevailing winds. The principle of the air currents created by the tropical regions and the polar regions Is described, showing how air mass deflects to the right in the northern hemisphere, to the left In the southern hemisphere and moves upwards in equatorial regions. Maps and diagrams also show the zones of the prevailing westerlies, trade winds and the way in which warm, moist air rises, cools by expansion, loses its moisture by precipitation, and so on."
