It shows the formation of rain and how the atmosphere works with surface water, how it la necessary to the formation of soil and in fact for life 55 1 .3 1 Glaciers BIRTHPLACE OF ICEBERGS. TFC llmin sd * (Father Hubbard's adventure ser) apply 551.31 Jh-sh-c-ad Produced by 20th Century-Fox "EJxcellent study of the largest tidewater glacier In the v/orld which discharges into the Gulf of Alaska. The ice river is shown moving down to the sea where It collapses, discharging tremendous chunks of ice — ■ Icebergs — an awesome phenomenon. "The two contradictory theories of iceberg formation due respectively to weight and pressure of water — are clearly presented. Commentary by Father Hubbard and Lowell Thomas is excellent and includes thunderous roar of iceberg formation. Photography excellent. "Excellent for geology courses at any age level. Suggested for Alaskan geography." Advisory committee "Overrated — shows glaciers but theory is overplayed." Collaborator GEOLOGICAL WORK OF ICE.

In rapid succession many uses of water are shown, such as its part in the growth of vegetation, Are fighting and lumbering. It shows how water's potential energy Is transformed into kinetic energy of electricity. Water's use in Irrigation and the water supplies of cities and towns are shown.

The film brings to our attention many phenomena that take place constantly below the surface of the earth, often without making themselves known. Artesian systems, springs, water tables, caves, wells, and artesian wells are explained by animation and illustrated photographically. "Other more spectacular phenomena such as geysers, roaring springs, hot springs, sink holes, petrification, concentration of useful minerals, and geode fillings are explained and illustrated by the outstanding examples to be found in this country."

The physical and chemical action of water and atmosphere on strata and deposits are illustrated by the formation and growth of stalactites, stalagmites, spattercones, helictites and oolites "Not one of the big caves but the film offers clear explanation of cavern interiors."

We can actually see and experirnce the subsidence of the mouth of the Hudson River to form the present harbor of New York; the events that have preceded In the story of the Appalachian Mountains; and the story of the famous and spectacular Lewis Overthrust In the Rocky Mountains. "The film opens with a photographic survey of the type of evidence which constitutes the basis of these interpretations, and closes with a consideration of the significance of these phenomena to mining and structural engineering." Iowa University "Best suited for college. Could be used In a high school, general science class, but worthwhile." Newark THE MOUNTAINS.

The remainder of the film is divided into three Illustrated parts as follows: water is life, water is power, and water is nature's sculptor. It contains an excellent animation of the water cycle."
