In illustration of the extraordinary development of the iron interest consequent 

 upon the use of anthracite coal, I give the subjoined synoj^sis of 1833, respecting the 

 Iron Works of Lancaster County: 



IRON ORES OF LANCASTER COUNTY. 



" The iron ores of Lancaster county are almost entirely limoniie or hematite; a few 

 small veins of magnetite ores have been discovered, but they are unprofitable to operate. 

 The great deposit of orejis Chestnut Hill, situated about 7 miles from Lancaster and 3 

 miles from Columbia, in West Hempfield township. This ore is found in a gorge of 

 the primitive formation, rests upon the primal white sandstone, is overlaid by argilla- 

 cious slate and bounded at its outlet of the gorge by the limestone valley. The ore is 

 of the best quality for all purposes of manufacture except that of steel, and is consid- 

 ered almost of a neutral quality, yielding from 40 to 55 per cent, of metallic iron. The 

 ore property there is now owned in difterent tracts by C. B. Grubb, heirs of E. B. 

 Grubb, Chestnut Hill Iron Ore Company, Silver Spring Iron Ore Company, other par- 

 ties owning small out-croppings of the main de]wsit. The mine was worked to a very 

 limited extent in the latter part of the 18th century, but since 1883 to the present time 

 1,000,000 tons may safely be given as the quantity taken out.
