million board feet, equivalent to 3 to 5 million board feet of lum- 

 ber; and the total lumber cut was probably between 40 and 50 million 

 board feet. This makes a total annual use of 51 to 70 million board 

 feet, exclusive of the wood used for ties and fuel. The years 1911 

 and 1912 may be taken as representative or average years. The sta- 

 tistics for these years show an annual demand as follows : 



Logs exported from the United States (1912), 9.82 million board 

 feet ; equivalent in lumber to about 12 million board feet. 



Logs manufactured into veneer in. the United States (1911), 4.12 

 million board feet ; equivalent in lumber to about 5 million board feet. 



Lumber production in the United States, estimated at 50 million 

 board feet. 



Total, 67 million board feet. 



Reports of wood-using factories in the United States during the 

 years from 1909 to 1913 show a total annual use of about 24 million 

 board feet of black-walnut lumber and veneer for the manufacture 

 of various products. As about 55 million board feet of lumber and 

 veneer were manufactured annually in the United States in 1911 and 

 1912, the difference of 31 million board feet represents exportations, 

 which were almost altogether in the form of lumber. The amount of 

 walnut used for ties, posts, and fuel is difficult of estimate, but is 

 small, compared with the total for all purposes. 



During the war the demand amounted to about 90 million board 

 feet annually. In 1918 the total lumber production was about 100 

 million board feet, which was cut for war purposes. There was no 

 exportation of logs, and practically no veneer was produced that year. 



The home demand for walnut at present is comparatively great 

 on account of the marked increase in its use for cabinetwork. The 

 total future demand depends very largely on the extent to which 

 exportations approach or exceed the amounts sent abroad before 

 the war.

Table 5 shows by States the reported amounts of walnut lumber 

 produced in the different years for which statistics are available. 

 The computed annual production of walnut lumber is also given for 

 the years 1915 to 1918. This table shows that the annual production 

 of black-walnut lumber in the United States for the past 15 and 

 probably 20 years did not greatly exceed 50 million board feet up
