Although growth has increased, a large share of it 
is concentrated on trees under 12 inches; the larger 
size timber is still being cut faster than it is being 
_ replaced by growth. Also, a large part of this growth 
_is on widely scattered trees in stands too thinly 
_ stocked to be logged profitably. 
This increase in growth, coupled with the reduction 
in commodity drain, appears to have arrested, tem- 
porarily at least, the downward trend in timber vol- 
ume. A surplus of growth over drain was achieved in 
1948, but at a very low level of forest productivity.
