In all the wells bored, a similar succession of strata has been pierced. 
The chocolate, the Hrie, and the Huron shales were struck in all wells 
carried deep enough. The rocks included between these and the Coal 
Measures present alternations of sand-rock, argillaceous and sandy shales, 
which, after passing the olive shales that cap the Waverly, present a 
great variety in the different wells, and forbid all minute systematic 
subdivision. The most marked and most general alternations ure exhib- 
in the general section of the rocks of the county. 3 : 
In nearly all the wells bored, gas, oil, and brine have been found in 
greater or less quantities, and from two of them a remarkably strong flow 
of gas has issued, which, properly utilized, can be made of great value. 
The employment of natural gas elsewhere in the manufacture of iron 
would indicate the proper use to be made of it were it not that the wells 
are situated several miles from any railroad or other adequate means of 
transportation. | 
The Neff Petroleum Company, which, under the management of Peter 
Neft, of Gambier, made the explorations for oil, has been recently reor- 
ganized under the name of “The Kokosing Oil Company,” and has at- 
tempted to utilize the gas in a novel manner, which gives promise of 
complete success. It has expended about $25,000 in erecting build- 
ings and appliances for the manufacture of carbon-black, and is now ob- 
taining a product not excelled in quality by any thing in the market, 
except. bone or ivory-black, and has demonstrated that the well has a 
capacity of producing about five hundred pounds per day of No. 1 black, 
which is said to command, at wholesale, eighty cents per pound. This 
company has also devised a mode of utilizing the acid-waste of oil refin- 
eries, aS it makes a very excellent carbon-black from that of ordinary 
quality, by using with the acid-waste a small amount of the natural gas. 
With eighteen hundred burners, for the consumption of the natural gas, 
it produces from forty to fifty pounds of the “ Diamond,” or No. 1 black, 
per day, and with twenty-eight burners, for the consumption of the acid- 
waste, one hundred to one hundred and fifty pounds per day of the 
“Pearl,” or No. 2 black. The fact that the gas has flowed from the well 
without diminution for ten years gives good promise of its permanency; 
and the indications now are that by this use of the gas a good return
