The millvalues of lumber in the U. S. have increased 38o/o, 

 from 1900 to 1Q08. Here it is interesting to find, from German 

 statistics, that the average value of all wood goods sold from 

 the Prussian stateforests has increased 47o/o, from 1898 to 1908. 



The consumption of mining timber might be guaged from the 

 fact that the production of one ton of coal requires t\x-o cubic 

 feet, and the production of one ton of iron 20 cubic feet of 

 mining timber (Dr. D. D. Hayes at the 1905 Forest Congress 

 in Washington). 



The consumption of timber for railroad ties (in the U. S.) is 

 such that two trees should be kept growing continuously at 

 the side of each tie (Gifford Pinchot). 



For repairing purposes alone, our railroads require 300 ties 

 per mile per year ; or, approximately, 75 million ties (at 40 feet 

 board measure each) per annum. Two-fifths as much oak timber 

 is required for (hewed) ties as is for lumber. The southern pine 

 furnishes nearly 18 per cent of the hewed ties, and cedar and 

 chestnut about 8 and 7 per cent respectively. Of the entire 

 tie-consumption, three quarters consist of hewed ties, and one 

 quarter of sawed ties. 



The total number of crossties used in the U. S. was 



in 1907 154 million crossties 

 in 1908 112 

 in 1909 124 



The consumption of shingles in the U. S. approximates 

 15 billion pieces per annum, of which the western cedar furnishes 

 three-fifths. 



The consumption of pulp v;ood in the U. S. amounts to 

 approximately 4.0 million cords, one-fifth of which are im- 

 ported from Canada. 



Three-fifths of the pulp wood consumed by us consists of 

 spruce, and one-fifth of hemlock. 



The consumption of tight cooperage stock in the United 

 States requires approximately 250 million staves and 18 million 

 sets of heading; the consumption of slack cooperage consists 

 of over one billion staves, 125 million sets of heading, and 

 over 330 million barrel hoops.
