EDUCATIONAL FILM CATALOG 551.48-551.5 Sculpture of the land by rivers— Contmued plishes two things; first, gives a good con- ception of the slow, but relentless wear of the land surface by running water, as seen in the case of Ausable Chasm, the Dales of the Wisconsin River and the Grand Canyon; and second, shows, by means of an experiment on a small scale in the laboratory and by views of several streams just how a river does Its work, eroding the land and transporting the debris."

Atwood "Illustrating the evolution of river val- leys through youth, maturity and old age . . . Shows how through thousands of years rivers convert the land into a succession of broad valleys. At first the valleys are steep and sharply cut. Diagrams illustrate how young valleys like the Royal Gorge of the Arkansas and the Grand Canyon of the Colorado were formed, and then the screen shows them in motion picture. As maturity approaches, the steep walls be- come rounded slopes. In old age the val- ley is broad and low, the home of a slow, winding stream." Producer Jh Guide Work of rivers.

The main story is intro- duced with a brief portrayal of the water cycle in nature. A comprehensive presen- tation of the cycle of a river from its very beginning to old age follows. The main story is integrated by motion pictures, specially taken for the picture, presenting examples from many parts of the country. Models and animated cartoons are em- ployed to explain such special features as Niagara Falls, deltas, meanders, ox-bow lakes, rejuvenated rivers, lakes, water gaps, and sand bars."

Models and scenes from all parts of the world show how running water wears away the land. Many picturesque evidences of ero- sion are analysed. 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 jh-sh-c Guide Work of the river. ISmin 16-si-$24 35-si- nf-$60 1929?

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, petrifica- tion, concentration of useful minerals, and geode fillings are explained and illustrated by the outstanding examples to be found in this country."

Caves, sink holes and natural bridges sculptured by ground v/ater because of its ability to dissolve mineral matter, as well as springs, artesian wells and geysers are considered. Animat- ed drawings are extensively used to ex- plain these phenomena. Actual photo- graphs from the Great Diamond Cave of Arkansas show the results of deposition."
