52 LOBLOLLY OK XOBTH CAROLINA PIXE. 



USES. 



Loblolly pine lumber under the trade name of Xortli Carolina pine 

 is used for finishing, packing boxes and construction purposes. If 

 sawn into boards the lumber is generally kiln dried and graded, a large 

 part being reworked at the mills into finished products. The clearer 

 grades are used for flooring, especially when rift sawn (6 to 12 annual 

 layers to the inch particularly suitable) for which use it is especially 

 adapted on account of the fact that it slivers less than most of the pines, 

 for ceiling, interior woodwork, styles and panels of doors, for blinds, 

 sashes, weather boarding and trimmings, and the lower grades for box 

 stock, framing and scantling, bridge, factory,* and heavy construction 

 work. It has extensively taken the place of white pine or has supple- 

 mented it for structural uses, being found in all markets from Pittsburg 

 and Xorth Touawaiida to Boston and certain ports in Maine. The ex- 

 ports have likewise been steadily increasing, going chiefly to English 

 and German ports. 



It enters extensively into car construction, particularly for siding and- 

 roofing, and into ship, boat and barge construction. A large amount 

 of medium and low grade stock is used for box-making, slack cooperage, 

 and headings, and it is now one of the best recognized woods in the box 

 and slack cooperage trades. Slabs are resaivn into lath and copper 

 sticks for smelter use, and cut on a horizontal band saw into heading and 

 crate stock. A small though constantly increasing amount is used both 

 treated and untreated for mine timbers, chiefly in the anthracite fields 

 of eastern Pennsylvania. Mine timber is sold by the ton, from 4 to 5 

 tons of green timber being required to produce 1,000 board feet log 

 scale. The price per ton, green at Xorfolk, depending upon the size of 

 the timber, varies from $1.50 to $3. It is also cut into veneers, the 

 lower grades being used for fruit and vegetable crates, barrel and keg 

 stock, drawer bottoms, and the backs of cheap furniture. It is be- 

 ing used to a limited extent for chemical paper pulp stock, and this 

 is doubtless one of the most important undeveloped uses for the wood. 

 On account of the resin it cannot be used for ground fiber pulp and for 

 this reason cannot compete successfully with spruce in the manufacture 

 of newspaper and cheap book paper. On account of its great weight, 

 however, unbleached papers can be successfully made. The wood fibers 

 are very long, strong, thickwalled and tough which permits the manufac- 

 ture of very superior wrapping, kraft and imitation Manila papers 

 which are stronger than the real Manilas. The wood can be treated by 



•Dense wood to meet the proposed yellow pine grading rules for factor>' structural timber must 

 have between the third and fourth inches from the pith one-fourth of the volume summer wood if 

 there are eight rings to the inch; one-third if there are six or seven rings to the inch; and one-half if 

 the wood averages four rings to the inch. The wood shown in Plate VII, A and B meets these 

 specifications. Such wood is produced on the best class of flatwoods soils. (See Loblolly pine on long- 

 leaf pine flat lands). The Panama Canal requires only six rings to the inch between the third and 

 fourth inches. The Georgia-Florida Sawmill Association requires a minimum of six rings to the inch 

 between the third and fourth inches and one-third summer wood.
