1910.] Timber Supply of the United States. 1021 



The forests are divided into two great groups, the Eastern 

 (including the Northern, the Central Hardwood, the Southern, 

 and the Tropical forests), and the Western (including the 

 Pacific Coast and the Rocky Mountain forests). The follow- 

 ing table gives a comparison between the present and the 

 original forests.

The figures show that the "stand" has, in every instance, 

 decreased in greater proportion than the acreage, or in other 

 words the biggest and best timber has been removed. 



With regard to "stumpage" estimates of different species, 

 Douglas fir comes first with 525 billions of board feet, 

 followed in order by Southern yellow pine (350 billions), 

 Western yellow pine (275 billions), redwood, Western 

 hemlock and Western cedar 100 billions each. Hardwoods 

 total 500 billions, and the total for all species is estimated at 

 2,500 billion board feet. The timber cut in 1907 exceeded 

 20 billion cubic feet, with a value for forest products of 

 $1,280,000,000. Nearly three-fifths of this value was made 

 up of lumber, shingles and laths, and about one-fifth of 

 firewood. 



Southern yellow pine supplied 13 billions of board feet of 

 the lumber, Douglas fir 4§ billions, white pine 4 billions, oak 

 3J billions, and hemlock 3J- billions. The supply of white 

 pine has decreased from 8^ billion feet in 1890 to 4 billions 

 in 1907, while the supply of yellow pine promises to give out 

 in the next fifteen years at the present rate of cutting. On the 

 other hand, the output of Douglas fir is increasing rapidly. 

 The total hardwood cut in 1907 was 9 J billion feet, made up 

 of 40 per cent, oaks, 10 per cent, maple, 7*9 per cent, yellow 

 poplar, 7*5 per cent, red gum, an4 others.
