LOBLOLLY OR NORTH CAROLINA PINE, 53 



the soda or sulphate processes to effect the destruction or partial destruc- 

 tion of the resin and disintegration o£ the fiber; or after being chipped 

 the resin can be distilled off. There is a loss in weight by these processes 

 of about 50 per cent; consequently a cord (128 feet) of peeled wood 

 weighing about 3,000 pounds will make only about 1,500 pounds of 

 paper. At present comparative prices of kraft paper and N'o. 4 lum- 

 ber, low grade timber is more profitably converted into paper than into 

 lumber since the very knotty tops can be utilized by the chemical pulp 

 processes. A mill at Koanoke Rapids is now employing such a process 

 in the manufacture of kraft paper for wrapping purposes. 



While the Avood of loblolly pine is less suitable than that of spruce 

 for the manufacture of composition board on account of the great loss 

 in weight resulting from the necessity of using a chemical process to 

 disintegrate the fibers, it is, on account of its cheapness and great weight, 

 being successfully employed for this purpose. A plant for the manufac- 

 ture of composition board is also in operation at Roanoke Rapids. 



It is also being used for the production of Avood alcohol, the resin 

 being first distilled after Avhich the alcohol is produced. A large plant 

 for the production of Avood alcohol from sawdust and Avaste has recently 

 been erected at GeorgetOAvn, S. C. The AA^aste can also be used for 

 the production of producer gas. This is a recent process the employ- 

 ment of which will enable a large amount of power to be obtained from 

 mill waste in excess of the requirements of the sawmill plant. 



ISTorth Carolina pine is extensively used for cross arms for electric 

 Avires. wire poles and for light railroad ties, being well suited for these 

 uses after treatment Avith preservatives. On account of its softness 

 and susceptibility of abrasion it can not be used as a tie for lieaA-y 

 trafiic without a tie plate. Near the coast the timber is extensively 

 used for piling; sticks of timber exceeding 100 feet in length being 

 occasionally required for this use. Treated with preseiwatives it is 

 being used for street paving blocks, the heavy types of wood with not 

 less than 8 rings to the inch being required. It is very extensively used 

 throughout the coastal plain for fuel for manufacturing as Avell as 

 domestic use, and to some extent for charcoal. N"ear toAvns such mill 

 Avaste as is otherwise unusable is converted into fuel billets and kindling 



AA'Ood. 



COMMERCIAL VALUE FOR TURPEXTIXE.* 



The loblolly pine exudes an oleoresin Avhen Avounded, which is occa- 

 sionally in fairly remuneratiA^e quantities, but as a rule the yield of 

 crude turpentine is so much less than from the longleaf and Cuban pines 

 (the common commercial sources of crude turpentine) that no general 

 tapping of this tree is practiced. 



The oleoresin exudes from the wounded tree as clear limpid drops. 

 RoAA^ever, crystallization of the dissolved acids takes place very rapidly, 

 so that much of the material remains sticking upon the scarified surface
