est. In the great future struggle these ores will be the blackband ores* 
and the usual Coal Measure limonites, as factors in the competition. 
Fortunately Ohio is well supplied with both classes of ore, and it is be- 
lieved that mineral fuel now known to exist, or yet to be found, will 
make it pos* ‘ble for Ohio to supply the West with all the foundry iron 
it will need. If to this statement we add what appears to me to be 
among the certainties of the future, that to the cheap and abundant 
coal of Ohio no inconsiderable part of the rich ores for steel making will 
be brought to be smelted, the State may well be congratulated on its 
vast mineral resources, and the great industries of which they will form 
the basis. 
_ Drift.—The Drift formation is found abundantly in all the regions 
drained by the upper waters of the Hocking River, in Perry and Fairfield 
counties. In the valleys wells have revealed the blue bowlder clay, in 
which buried wood is often found. Gravel and bowlders are everywhere 
to be seen, even on the highest lands. Most of the bowlders are granites, 
quartzites, etc., but sometimes fossiliferous limestones ate met with. Mr. 
Hyde, of Rushville, has obtained many interesting paleeozoic fossils from 
the Drift in that neighborhood. Recently, Mr. Silas Courtright has 
shown me, in the northwestern part of Fairfield county, striated rock 
surfaces in the Waverly sandstone, where the strie are very distinct. 
The more usual direction of the striz is S. 623° Hi. 
* Since the foregoing was written, I have published a private report to the President 
of the Cleveland, Canton, Coshocton & Straitsville R. R. Co, in which I have authen- 
ticated very large deposits of blackband ore over Coal No. 5, situated on the upper 
waters of Sugar Creek (south branch), in Tuscarawas and Holmes counties. This ore 
is directly on the line of the railroad from Cleveland to the Upper Sunday Creek Valley, 
and must in the future be smelted by the fine fuel from that valley.
