ever, large areas have little but scrub oak on them — 
and will not produce stands suitable fer naval stores 
operations for many years, if at all, unless artificially 
reforested. 
The future wood-supply outlook for the wood 
naval stores industry depends a great deal upon 
whether small stumps from second-growth trees and 
other less resinous wood can be used eventually. The 
old-growth stumps in Florida totaled nearly 30 mil- | 
lion tons in 1949. Not all of this supply is available 
to the industry. Two percent is in inaccessible areas, 
5 percent is unworkable at present because of the 
density of timber on the land, and another 4 percent 
is regarded as marginal, i.e., the stumps are on areas 
less than 25 acres in size or the areas have already 
been partially worked for stumps. Of the remaining 
27 million tons of merchantable stump volume, only 
two-thirds is recoverable under existing practices. 
Thus only 18 million tons are readily available to the 
industry, or a 24-year supply at the present rate of 
use. 
Considering all sources of naval stores products, 
such as pine trees, stumps, and pulping waste, there 
seems to be little danger of a shortage of raw ma- 
terials in the foreseeable future. However, shifts in 
the importance of these various raw material sources 
will undoubtedly continue.
