Mineralogy of Pennsylvania by

Second Geological Survey of Pennsylvania, 1874
At present the state of the chrome ore business in this State is in a deplorable condition; the only mines where work was done last summer were the Wood’s Mine and Low’s Mine (or Line Pit), in Lancaster county, both owned by the Tyson Mining company, of Baltimore; and the only stream where gravel washing was carried on was the "Black Run", near the Octararo, which was worked by Mr. E. Mortimer Bye, of Wilmington.
