A second point to consider is that the Survey data 
are for provinces of several million acres and there- 
fore may not reflect accurately conditions in smaller 
specific areas. When data are grouped into State 
tables, the figures may be even more misleading be- — 
cause gross deficits in one section may be masked by 
surpluses in another. Nevertheless, the data here pre- 
sented do indicate the trends in the relation of growth 
to drain during the 6-year period since the original 
survey for both the State and its provinces. 
Saw-Timber Balance 
The net change in growing stock over the 6-year 
period (January 1, 1940, to January 1, 1946) is sum- 
marized in table 23. In using these data the reader 
is cautioned against considering the values as precise 
measurements of change. The original 1940 inventory 
was considered accurate, but annual changes since 
then have been based upon the difference between

computed growth and measured drain. 
The over-all figures for the State are encouraging 
and point up the high productive powers of Virginia’s 
forests, for, in spite of heavy cutting to meet war de- 
mands, 1,738 million board feet of saw timber were 
added to the growing stock. This is a net “earning” 
of 7 percent on the 1940 “capital” of growing stock 
(fig. 63). 
Less reassuring are some of the details of this in- 
crease. Although the softwoods showed little change 
in total volume, there was a serious reduction in short- 
leaf saw timber in the Piedmont.
