WORLD IN A MARSH 



Color Sound McGraw-Hill 



22 minutes Rental Sale 



The ecological story reaches a new high in beauty and significance 

 in this meticulous filming of an animal and plant community known 

 as a marsh. For thousands of years insects as well as plants and 

 animals have become adapted to this strange floating world. The 

 camera acts as a microscope in probing into the life forms that 

 dwell beneath the water's surface, recording the habits as well as 

 the habitats of the creatures involved. A particularly effective se- 

 quence of the birth of a dragonfly, a novel presentation of the court- 

 ing of the newt, the activities of the bullfrogs and the life cycle 

 of the marsh plants are delineated with great care and a sensitive 

 hand. The story adds up to a striking visualization of the balance 

 of nature plus a most effective emphasis on the interrelationship 

 between the plants and the animals. An intimate view of a micro- 

 scopic world of nature.
