UTILIZATION OF BLACK WALNUT.

smooth sheet without splintering. Moreover, the veneer warps very 
little in drying, glues very satisfactorily, and after it is made into 
panels does not shrink or swell excessively under varying moisture 
conditions. 
PRODUCTION. 
Data on the output of walnut in the form of veneer are available 
from reports of the Census Bureau for the years 1904 to 1911, in- 
clusive. The amounts of walnut logs used in different years are 
given in Table 15, and also the cost of the* logs per thousand board 
feet, log scale, where reported. Approximately 95 per cent of the 
total amount for the years 1906 to 1909 was used for rotary veneer. 
Eeports for those years are given by States and are shown in 
Table 16.

1 This figure was obtained by using an average converting factor of 12 square feet of veneer to each board 
foot, log scale, derived from reports for the years 1905-1907, as reports for 1904 were only on veneer pro- 
duced.
