PLATE XV. 



Unthinned stand 80 years old, Quality II, on permanent loblolly pine site, in process of lumbering. Although 

 of good size, the upper logs are prevailingly knotty. This stand would have been benefited by the 

 removal of the dominant trees 25 to 30 years ago. Scale of average log about 50 feet, D.-S. Such 

 a stand will yield 30 per cent of lumber of Grades No. 1 and No. 2. Desirable type of seed trees 

 marked "S." (Author's illustration.)
