general use, for many purposes, especially where it will not be
exposed to the weather.

Logs frequently seven feet in diameter require big saws, and big
carriers 50 to 100 feet long, and hence Washington has probably
the largest sawmills in the world.

Our lumber is used at home and shipped all over the world to make
bridges, ships, houses, floors, sash, doors, boxes, barrels, tubs,
etc. Factories for the manufacture of wood products are scattered
all over the state. Most of the sawmills and some factories are
driven by steam made by burning sawdust, slabs, and other refuse
of the mills. Coal and electricity, however, are both in use.


COAL MINING.

The mining of coal for foreign and domestic purposes is one of
the most important of Washington's industries. The annual output
of the mines is about three million tons, worth about eight million
dollars; Fifty thousand tons of coke are made annually, worth at
the ovens about $300,000. The coal mining industry gives employment
to 6,000 men. The production of coal for 1907 was distributed as
follows:

Kittitas County, tons 1,524,421
King County, tons 1,446,966
Pierce County, tons 612,539
Lewis County, tons 101,275
