Wood-using industries of Pennsylvania
A 1914 state forestry survey by Roger E. Simmons, printed at Harrisburg by state printer W. S. Ray, reporting to Pennsylvania lumbermen and manufacturers on which woods their factories consumed. Halftone photographs show mill interiors, stacked boards and sawn blanks, belt-driven machinery, drying yards and workmen at benches, all in coarse grey screens useful for industrial texture and machine silhouettes.
