GROWTH IN THE ORIGINAL FOREST. 
It is interesting to compare the growth in diameter of trees growing 
in the original forest with the figures just given for cut-over land. 
Stem analyses were made on 298 trees in original forest near Nehasane, 
from which the table given below has been compiled. These measure- 
ments were taken at a lumber job on the southern edge of Nehasane 
Park and on the Brandreth tract. 
Rate of growth in diameter for the last 10 years, from measurements of 298 trees in 
Nehasane Park.
