Book excerpt: Excerpt from Coal-Mining Problems in the State of Washington Coke is made only in Pierce County by four companies, which have a total of 341 beehive ovens. In 1918 they produced tons of coke. Up to 1919 mining machines were little used in the State. In 1917 only per cent of the coal produced was undercut by ma chines. In that year per cent' of the coal was mined by hand, and per cent was Shot Off the solid. The explosives used were as follows: Black powder, per cent; dynamite, per cent; and permissible, per cent. The State of Washington is divided naturally into two parts by the Cascade Mountains which extend north and south somewhat west of the middle of the State. The coal areas east of the range will hereafter be referred to as eastern Washington - though nearly all of it is west of the middle of the State - and that on the west side as western Washington. The geographical distribution of the coal fields is shown in Plate I. Exploration of the State has not been exhaustive enough to preclude the possibility of discovering, besides the foregoing, other districts that contain deposits of coal in commercial quantities.
