FOREST CONDITIONS IN TENNESSEE.

The development of second-growth white oak after logging, with much better 

 light conditions, is considerably faster than that of virgin timber. Measure- 

 ments of second-growth white oak were obtained in Decatur County, Tenn., on 

 lands which were cut clean for charcoal from fifty to sixty years ago. The rate 

 of growth of this young timber in height, diameter, and volume is given in Ta- 

 bles 3 and 4.

The better soil and moisture conditions found on the cove and slope lands 

 produce more rapid growth in height and diameter than on the ridges, and much 

 more rapid volume increment.
