INTRODUCTION. 



for Shortleaf and Loblolly Pine was calculated from "stem analyses" 

 of the same number of specimens. These stem analyses included the 

 following measurements: 



Diameter at 4.5 feet from the ground. 



Diameter on the stump and at the top of each log, inside and 

 outside the bark. 



Height of stump. 



Length of each log and of the crown. 

 The rings were counted on the stump and at the end of each log, 

 and the distance to each ten-year point from the bark was measured. 

 From these measurements it was possible to ascertain the rate of 

 growth of the trees both in height and in diameter. No investigations 

 were undertaken of the rate of growth of the hardwoods. 



The field expenses necessary to the preparation of this working plan 

 were borne by the Sawyer & Austin Lumber Company.
