14 BULLETIN" 909, U. S. DEPABTMENT OF AGRICULTURE, 
suitable for the growth of walnut, but in fertile sections and valleys 
there is much walnut available. The eastern portion of Ohio is in 
general very rolling, and this area has the largest amounts. There 
is much nonagricultural land here among the hills and valleys. 
Fertile, moist slopes and valleys contain some excellent stands of 
the best quality of forest-growth walnut. In northeastern Ohio 
the walnut is scattered, is generally below the average in size, is 
likely to be limby, and shows a large proportion of one-log trees. 
ARKANSAS-OKLAHOMA-TEXAS REGION. 
[Estimated stand.. 101 million feet.] 
Walnut is of commercial importance in the Arkansas-Oklahoma- 
Texas region principally in eastern Oklahoma, northwestern Ar- 
kansas, and northeastern Texas. It is generally confined to fertile, 
moist locations along the streams, but avoids the low, wet bottom 
lands. The best walnut has been removed from this region, except 
in the rough, inaccessible areas, and these are chiefly in Arkansas. 
The greater part of the walnut in Arkansas lies in the Ozark 
region north of the Arkansas River. Throughout this region there 
are many valleys which have a rich, moist, deep, loamy soil. In such 
valleys and on moist hillsides there are good stands of walnut of 
large size. The forest-growth walnut of this region is said to yield 
a higher percentage of clear material than that from farther north 
in Iowa and Missouri, which is largely open growth. A considerable 
amount of walnut is said to have been taken out of the northwest 
corner of Arkansas in recent years. 
In Oklahoma and Texas the walnut is generally very limby and 
defective. In Oklahoma the best walnut is found on the fertile allu- 
vial soils of the bottom lands, along the stream courses of the north- 
eastern and east central parts of the State. Practically all of the 
desirable black walnut in the State is found east of the ninety- 
seventh meridian, principally along the Arkansas, Verdegris, Cana- 
dian, and Red Rivers. The black walnut west of this line is small in 
size, short-boled, scrubby, and very defective. 
In Texas the best walnut is in the extreme northeastern part, and 
.particularly in the Red River valley, but even this is rather poor in 
quality. In general, the black walnut is found north of the thirty- 
first parallel and east of the ninety-seventh meridian. In eastern 
Texas the walnut is largely confined to the better- drained, but moist, 
bottom lands. Along the larger rivers these bottom lands are fre- 
quently 5 miles or more in width, and the soil is rich and deep. If 
the soil is not too wet, walnut makes a good growth here. However, 
the more valuable timber has been removed from these localities. 
Present supplies usually stand 10 miles or more from the railroad.
