LONGLEAF PINE. 13 



season after the fire the growth averaged 18.1 inches, still a little 

 below the general average. 



PRODUCTION OF TIMBER. 



Second-growth longleaf pine is increasingly used for lumber, cross- 

 ties (to be treated), cooperage, boxes, crates, pulp wood, mining 

 timber, and fuel wood. Similar new uses for small-sized timber 

 with wide rings and coarse texture have been successfully found in 

 all the older timber-producing sections of the country. 



MEASUREMENTS of adjacent young longleaf stands, 

 one burned and the other unburned for a period of 

 five years, showed an average yearly growth under protection 

 of 18.4 inches, but of only 5.8 inches when burned over 

 every year. 



A tract of young longleaf saplings, under observation at 

 Urania, La., after being burned over yearly for five years, 

 contained longleaf saplings mostly up to 1 foot and none 

 over 2.8 feet in height, while in a similar tract protected 

 against fires one-sixth of the trees were over 2 feet and 

 others ranged up to 7 feet in height. The two tracts origi- 

 nally contained approximately the same number of longleaf 

 seedlings and both had been continuously protected against 

 hogs. 



The wood of longleaf pine is classed as heavy, hard, and strong. 

 It has been for many years the standard of the southern yellow 

 pines, and by far the leading wood of all southern species in point 

 of amount of production and total value. This applies, of course, 

 mainly to old-growth timber. Second-growth longleaf timber has 

 voider annua] rings and contains a higher percentage of sapwood.
