SUPPLEMENTAL REPORT—HOCKING VALLEY. S61 
ville coal. A similar block ore is found on the lands of the Crafts Iron 
Company at the mouth of Little Monday Creek, and at very nearly the 
same distance below the Nelsonville coal. It rests upon a flint layer— 
elsewhere a fossiliferous limestone~—with a thin coal beneath. This ore 
isnot thick (from four to six inches), but itis of excellent quality as 
seen from the following analysis by J. Blodgett Britton, kindly given me 
by Mr. Crafts:

The ore above a fossiliferous {imestone found in the hill back of the old 
furnace and thirty feet above the railroad, at Haydenville, doubtless 
belongs to this horizon as the instrumental measurements give it very 
nearly the same distance below the Nelsonville seam of coal. This ore 
was formerly mined, but probably no analysis of it was ever made. In 
1869, I found a rejected pile of ore at the Five Mile (Union) furnace, 
which doubtless belonged to the lower series of ores but its stratigraphical 
place was not ascertained. It had many years before been rejected because 
of the supposed excess of phosphorus in it. A sample of the pile was 
analyzed by Prof. Wormley and found to contain 42.53 per cent.. of 
metallic iron and only a chemical trace of phosphorus. 
An ore mined somewhat at Webb’s Summit, on the Straitsville branch 
railroad, and also said to rest upon a flint layer, has been analyzed by 
Prof. Wormley for the Thomas Iron Company, and Gen. Thomas has kindly 
given me the result, as follows:
