UTILIZATION OF BLACK WALNUT. 
9 
The area of principal or primary commercial importance is also 
indicated in figure 2. This area excludes the mountainous high- 
altitude region of eastern United States, the region east of those 
mountains, Texas, Wisconsin, Michigan, and parts of States whose 
remaining area is within its principal commercial range. 
SUPPLY OF TIMBER IN DIFFERENT REGIONS. 
Table 3 gives the estimated amounts of standing black-walnut 
timber, by States and groups of States, for trees 12 inches and over 
in diameter at breast height. This estimate is based on available 
data from various sources, and is subject to revision as more definite 
data are obtained. The amount of timber available for commercial 
uses is, of course, considerably less than this, because many walnut 
logs less than 14 inches in diameter at the small end are not mer- 
chantable. Moreover, much of the timber included in the estimate 
is. in small amounts too scattered to warrant its removal. A very 
large part of it is also inaccessible under present conditions; however, 
as conditions change, timber formerly inaccessible becomes accessible. 
Any statement, therefore, as to amounts available is mere conjecture.

The locations from which walnut timber has been recently ob- 
tained are given in figure 3. This figure shows graphically the wal- 
nut timber that had been purchased by mills cutting gunstock blanks, 
and which was in the woods and at sidings at the time of the cigning 
of the armistice. 
ILLINOIS-MISSOURI-IOWA REGION. 
[Estimated stand, 246 million feet.] 
Estimates of standing walnut timber credit the Xllinois-Missouri- 
Iowa region with approximately 30 per cent of the total. Large
