﻿FOREST MANAGEMENT OF LOBLOLLY PINE. 11 



not need to be considered, since future stands will be grown almost 

 exclusively on short rotations of less than 75 years. The red heart 

 grades (culls) of North Carolina pine lumber, provided for by the 

 grading rules of the North Carolina Pine Association, will be of no 

 importance after the old-growth timber is cut. 



UTILIZATION. 1 



OSES.* 



Both the use and value of loblolly pine lumber have increased since 

 the custom of seasoning it in dry kilns became common. Prior to 

 that time loblolly lumber frequently went to the market "green or 

 imperfectly seasoned. It is largely sapwood, especially in small and 

 medium-sized trees, and the water in it made it susceptible to attack 

 by fungi, which gave a blue color to the wood, and not only marred 

 its appearance but induced deterioration. Thorough drying in kilns 

 removed the cause for that objection, and loblolly speedily won an 

 important place in the market. Its range of uses is wide, and it is 

 sold throughout the eastern and central United States and exported 

 to Europe and Central America. 



The principal uses to which loblolly pine is put are: For building 

 lumber, such as interior finish, flooring, ceiling, frames and sashes, 

 wainscoting, weather boarding, joists, lath, and shingles; for boxes 

 and packages, in the form of boards and veneers, and in the manufac- 

 ture of slack barrels; in the manufacture of cheap furniture, wooden- 

 ware, toys, etc. ; for construction purposes, in bridge and trestle work, 

 in heavy building operations where the conditions are not such as to 

 require longleaf, and in car construction, chiefly for freight cars. 

 Much loblolly pine is cut for crossties, for which it is well suited after 

 being given a preservative treatment. It is among the most easily 

 treated timbers in the United States, and the recent developments in 

 wood impregnation processes and plants is rapidly increasing its use 

 for many purposes. It is extensively used for mine props in the 

 South and in Pennsylvania, frequently after being given a preserva- 

 tive treatment. Few pines if any exceed loblolly in use for fuel. 

 Immense quantities are shipped as cordwood for domestic purposes, 

 and find markets in towns in the loblolly region and in cities as far 

 north as Philadelphia. Its use for fuel purposes in manufacturing is 

 also extremely large, particularly in brick burning, pottery kilns, and 

 by bakers who demand a quick, hot fire. 



A report of the woods used in Maryland for manufacturing purposes 

 in 1909 3 shows loblolly as exceeding all other .woods combined (17
