PART III FOREST CONSERVATION 



The need for careful conservation of our forest resources is 

 brought home in this concluding film of the series. Careful lumber- 

 ing is outlined, with reminder of the damage caused by poor timber 

 practices. Mismanaged forest areas are shown, land which cannot 

 hold water and whose soil is washed away by rain, causing floods, 

 erosion, and filling of lakes and reservoirs with the eroded silt. 

 Scientific forestry methods sectional lumbering, reforestation, 

 spacing and thinning are illustrated. Special attention is paid to the 

 problems and difficulties of the small forest owner, and the film sug- 

 gests state and federal aid with the tending, harvesting and market- 

 ing of his crop and the cheaper purchase of stock. The responsibility 

 of every forest owner as a trustee, and the importance of his trust, 

 are emphasized in closing.

 principles and importance of the natural water cycle the continu-

 earth back again to the sea. This section covers the evaporation, 

 the forming of water vapor in the clouds, and the release of this 

 moisture as rain and snow. It is emphasized that the force which 

 moves the water lies in the heat delivered by the sun to the earth, 

 and in the ability of the water to store this heat. Fog belts and 

 thunderheads are explained, and documented, as well as an ex- 

 planation of watersheds, the natural basins that trap water and 

 divert it into streams or river systems. There is also a sequence on 

 underground water.
