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 gunstoek blanks, 

 and which was in the woods and at sidings at the time of the signing 

 of the armistice.

[Estimated stand, 246 million feet] 



Estimates of standing walnut timber credit the Illinois-Missouri- 

 Iowa region with approximately 30 per cent of the total. Large
