It is the intention of the Forest Service to have these models 

 set forth certain points in regard to the timber sales conducted by 

 the Government. They will demonstrate, in the first place, that the 

 Umber on National Forests is for use; placards tell how it is sola 

 to the highest bidder when it is wanted for commercial purposes and 

 how it may be given away to local settlers and prospectors for devel- 

 oping homesteads or mines* The models themselves indicate that the 

 timber is cut in such way as to eliminate all avoidable waste of wood 

 and secure a continuance of the forest crop not only for timber pro- 

 duction but for protection of the soil. They further s r how the fun- 

 damental principles applicable to many logging operations, - that the 

 mature and over-mature trees should be removed, that thriftily growing 

 young trees should be left to produce seed and insure reproduction of 

 the stand, and that the young growth should be ptotected from damage 

 in lumbering operations. 



The models are supplemented by a graphic chart which sho\,*, 

 by pictured piles of money and by conventional trees of graded sizo, 

 the increase of timber sales on national forests from 1905 to 1913, 

 inclusive. In 1905 the timber sold from the national forests aggre- 

 gated 96,000,000 board feet, which brought the government no more t~r> 

 585,000, Three years later the amount of timber sold increased to 

 nearly 390 million board feet and the mo nay received rose to 735, 00( 

 In 1911 830 million board feet sold for more than $2, 000,000; and ir:. 

 1913 more than two billion feet brought in contracts amounting to 

 $4,500,000. Not all this money was received in any one year, "be cars e 

 national forest timber is sold on contracts which range from one to 

 twenty-five years and it is paid for as cut.
