tion of 3,296,000 board feet, log scale, of logs in 1017, with a pro- 

 duction of 64,654,000 square feet of veneer, and an estimated con- 

 sumption of about 5,615,000 board feet of logs in 1919, with a pro- 

 duction of about 111,200,000 square feet of veneer. These figures 

 are given by States in Table 17. About 50 per cent of the total 

 amount is straight sliced and the other 50 per cent is about equally 

 divided between rotary proper and stay-log rotary. Of the total 

 amount of veneer produced, approximately one-half is plain and one- 

 half figured. During 1918 the cutting of walnut veneer, except 

 highly figured stock from cross-grained wood, was prohibited by 

 the War Department. Near the close of the year the cutting of 

 walnut veneer was resumed ; and the great demand that arose because 

 of depleted stocks, together with the large supply of walnut logs on 

 hand that had been purchased to fulfill Government war orders, ac- 

 counts for the marked increase in production shown for 1919. It is 

 also estimated that the 1920 walnut veneer production will be in ex- 

 cess of 100,000,000 square feet. The increase in the production of 

 veneer in recent years is greater than the log-consumption figures in- 

 dicate, for the amount of veneer obtained now is much greater from 

 the same number of feet, log scale, largely because of the cutting of 

 thinner veneer. For instance, in 1906, from 5,121,000 board feet of 

 logs, 67,184,000 square feet of veneer was produced, or 13 square feet 

 of veneer to 1 board foot of log; but in 1917 and 1919 the ratio of 

 square feet of veneer to board feet of logs, log scale, was about 20 to 1. 

 The estimated 1919 production was nearly double the reported pro- 

 duction of 1906, and the estimated log consumption of 1919 was only 

 about 9 per cent greater than the reported consumption of 1906.

MANUFACTURE. 



Walnut veneer is produced almost altogether by slicing, but small 

 amounts are still sawed for special purposes. Sliced veneer is made 

 by two processes — the rotary method in which the timber is rotated
