out the great spans of geological time necessary for major changes 

 in the earth's form and structure. The Grand Canyon is used as an 

 example of the formation of a great part of the earth. 



Of particular interest to ecologists, it offers a valuable introduc- 

 tion to the study of eras and epochs by giving many examples of 

 erosive action, particularly water, wind and frost. An elaborate 

 production in terms of music, narration and scope of story.

THE LIVING FOREST SERIES 



Color Sound Encyclopaedia Britannica Films 



Three parts; Rental Sale 



33 minutes complete 



PART I THE FOREST GROWS 



Different types of trees and forests, together with the climatic 

 and geographical variations which cause these differences, are de- 

 scribed. The film next defines these trees as citizens of the forest 

 community and demonstrates the duties they perform in this role. 

 Photosynthesis and growth are shown in remarkable time-lapse 

 photography. The changes in growing conditions from valley floor 

 to mountain top, and the resulting difference in forests and ground 

 cover, are then covered. The film goes on to explain the growth and 

 development of a typical New England forest, including the roles 

 of weather, animals, and the trees themselves. Finally it shows how 

 an overmature forest can be brought back to life by the under- 

 standing care of man. 



PART II THE FOREST PRODUCES 



The forest's three gifts to mankind are described in this film. 

 The lumber industry and its many products are sketched first. 

 Water is shown as the most important gift of the forest, and the 

 film explains how trees and forests help mountains store water and 

 regulate its flow, and how the water thus saved carries life to thou- 

 sands of acres of arid land. The third gift of the forests, provisions 

 of places of beauty and relaxation, concludes the film, with scenes 

 of our national parks and forests, and the geological history and 

 wildlife observable within. The reminder is made that man can 

 continue to receive these gifts as long as he manages his forests 

 wisely.
