VALUE AND USICS OF THE WOOD.

The timber from tlu; dami) Hat woods of the coastal plain east of the Mississippi River, with 

 a soil of alTiiost puie, line, closely compaeted sand, is of slow growth and <;ei>«'i':illy of the liuest 

 firaiii, often exhibiting- in the sapwood that irregularity known as "eurly pine." In the pcri)etually 

 damp to wet soil of the pine Hats in southwestern Louisiana and in Texas, with a deep retentive 

 subsoil richer in nutritive elements, causing a better and (piicker development of the tree, the 

 wood is of a more open grain. Owing to the excellent qualities of the wooil of I.ongleaf Pine, its 

 use in the various mechanical arts and industries is as extensive as it is manifold. Its greatest 

 value rests in its adaptability for heavy constructions— in naval architecture, for masts and spars; 

 in civil engineering, for the building of bridges, viaducts, tresthiwork, and for supports in the 

 construction of buildings. Large quantities of long and heavy sticks of s(iuare timber sawn or 

 hewn fur such purposes are shipped to the British ports and to the dockyards of the European 

 continent, with a constantly increasing demand. 



In the building of railroad cars, where great strength and elasticity is needed, the timber 

 of Long-leaf Pine is preferred to any other. For this purpose sticks Irom M) to 42 feet, 10 by 12 

 inches, are recpiired, free from blemish. 



Enormous (luautities of the younger timber of this tree are cut every year to serve for cross- 

 ties, used by the railroads not only in the pine regions, but in other parts of the country. The 

 deniand for these ties forms a constant and increasing draft npon the forest. The ties delivered 

 are, on the average. Si feet long, 9 inches wide, and 7 inches thick, and must be all heartwood and 

 free from blemish. The trees selected for this purpose are from 15 to IG inches in diameter, and 

 preferably only the butt cuts are accepted. On an average 10 cross-ties are cut from 1 acre, each 

 tie representing a log which would make at least 75 superficial feet of lumber. Since such a tie, 

 ready for the roadbed, contains not more than 50 feet, board measure, it will be readily seen what 

 an enormous waste results from this practice. 



On the damp, sandy tracts of the lower South, such ties will last five or six years, and 3,000 

 ties are needed for 1 mile of road. Hence, for the construction of the 3,240 miles of railroad 

 traversing the forest of Longleaf Pine east of the Mississippi River, nearly 10,0(10,0(10 ties have 

 been required, which being renewed every six years involves an annual cut of 116,000,000 feet, 

 board measure, to which must be added the amount exported to other regions. 



In the Southern States, the West Indies, many places on the coast of Mexico, and Central and 

 South America the lumber of the Longleaf Pine forms the chief, if not the only, material in the 

 construction of houses. For similar purposes considerable (pian titles are of late years shipped to 

 northern markets. East and West, replacing in many cases, at least in parts of the buildings, the 

 lumber of the White Pine, on account of its increasing scarcity. The fine-grained and "curly" 

 varieties of Longleaf Pine lumber, by their beauty and the high polish of which they are susceptible, 

 begin, of late years, to take a place among the higher-priced kinds of wood for ornamental inside 



work. 



The importance and value of Longleaf Pine lumber as a material for constructions can not be 

 ■ better evidenced than by the fact that little less than 1,.500,000,000 feet, board measure, or about 

 one-third of all the lumber manufactured in the South, is being exported from Southern ports annu- 

 ally to domestic and foreign ports, besides furnishing almost the only material used at home in the 

 construction of dwellings and all kinds of buildings. It also supplies material for furniture, as 

 well as fuel, both in the form of firewood and charcoal, and its exploitation affords the means of 

 subsistence to thousands. 



Liflhtiraod.— Whenever the sapwood of the tree is laid bare copious exudation of resui takes 

 place and the surrouiuling wood becomes charged with it. Thus the wood of the trunks of the 

 trees tapped for the extraction of their resin soon becomes charged with this along the scarified 

 surface, and, as with the evaporation of water from the dead wood, the resinification proceeds and 

 the wood increases in weight and dural)ility. In low, damp places particularly this process takes 

 place more extensively. This resin cliarged wood is termed lightwood. The lightwood timber, con- 

 sidered very durable when exposed to alternating conditions of moisture and dryness, is much 

 preferred for posts, etc. Ueing highly inflammable, it serves for torches and kindling, and hence 

 its name. Of late years a profitable industry has been started to utilize the resinous stumps of 

 abandoned orchards as kindling material by cutting the same close to the ground and then, veneer
