RATE OF GROWTH. 



White pine. White pine is the most rapid-growing tree of the Southern 

 Appalachians. The most rapid growth and best development are attained on sandy 

 or gravelly soils on north and northwest slopes, between elevations of 2,500 and 

 4,000 feet. The table below shows the rate of diameter increase by decades at 

 three different places. At Higgins Creek the elevation is the greatest and the 

 growth slowest. The best growth is made on Linville and New rivers, in Watauga 

 County, N. C, at elevations between 3,000 and 4,000 feet.
