REDWOOD. 
Redwood production was maintained in 1917 on the same scale as 
for the preceding year, the reported total output of 487,458,000 feet 
being less than 1 per cent smaller than that for 1916. The produc- 
tion figure given is believed to cover approximately all of the red-— 
wood cut. 
An exceptional advance of 51 per cent is noted in the average mill 
value over the previous year. The value reported was $21 per 
1,000 feet in 1917, a jump of $7.07 from 1916.

1 Redwood (Sequoia sempervirens) is the species chiefly cut. Bigtree (Sequoia washingtoniana) furnishes 
a minor part of the redwood production. 
BIRCH. 
The reported total cut of birch, amounting to 387,283,000 feet, 
was an increase of 6 per cent over the 1916 cut, and was occasioned 
by the heightened war demands. Wisconsin and Michigan, the two 
principal birch-producing States, increased their output over the pre- 
ceding year by 16 per cent and 4 per cent, respectively. The com- 
bined output of the two States formed 65.3 per cent of all birch 
reported cut in 1916 and 69.9 per cent in 1917. The number of mills 
which reported cutting birch in Wisconsin and Michigan in 1917 was 
367 and for the preceding year 410. Vermont's increase in cut from 
22,980,000 feet in 1916 to 30,882,000 feet in 1917 puts that State in 
third instead of fifth place in the rank of producing States. 
The average value of $24.07 per 1,000 feet reported for birch is 
$4.48, or 23 per cent, over the 1916 value.
