354 ECONOMICS OF FORESTRY. 



Texas, varying in width from 60 to 1 50 miles. In 

 its southern range it is joined by the Cuban Pine, 

 of equal or even greater value, although in the 

 market not differentiated, and by the Loblolly Pine ; 

 in its northern range it extends into the mixed 

 forest which covers a belt of 20 to 60 miles more, 

 in which the Longleaf Pine is associated with Short- 

 leaf Pine, in the market called North Carolina Pine, 

 with Loblolly or Oldfield Pine (called Virginia 

 Pine), and with hardwoods. 



North of this belt of mixed forest the pine area is 

 increased by the Shortleaf Pine, occasionally asso- 

 ciated with the Loblolly, occupying the sandy soils. 

 Although the Longleaf and Cuban pines are supe- 

 rior in quality, the other two have not much less 

 value and application in the arts, being often sub- 

 stituted ; and hence we can consider the whole pine 

 belt as a unity, an area of about 150,000,000 acres, 

 within which these pines do or did occur in mer- 

 chantable quantities. Deducting the farm area and 

 making allowance for hardwood areas interspersed 

 between the pineries, the pine-producing area is 

 probably not quite two-thirds of the area of distri- 

 bution, or round 90,000,000 acres. The available 

 supplies of standing timber were estimated by the 

 writer seven years ago at between 200,000 and 

 300,000 million feet. At that time the annual cut 

 exceeded 7,000 million feet, and as it has con- 

 stantly and rapidly increased, the waning white- 

 pine supplies stimulating the Southern lumber in-
