contracts to insure the reproduction and sustained yield of the forest. 

 Bids are invited after public advertising, and the sale is awarded to 

 the highest bidder. Many lumbermen cut timber from both private 

 and federal properties to supply their log requirements at sawmills. 

 Recently few sales have been made from National Forests because 

 the lumber markets have been generally flooded with an adequate 

 supply of privately owned timber for many years.
