northwestern corner of the county with more than ordinary success. The 
gas has been found at depths ranging from 130 feet or less down to 1,400, 
and is used for fuel and light by those citizens fortunate enough to possess 
it." Many of these wells were drilled 20 years ago, but more recently a 
number have been drilled in other parts of the county, and several have 
passed entirely through the shales into the great limestones below; one on 
the Hayes farm in Cherry township, drilled about 1897, is reported to have 
attained the great depth of 2,775 feet, but no information has been secured 
as to the strata passed through, and the depth given may not be correct. 
The well was a failure. In 1899 a well was drilled by the Jefferson Oil & — 
Gas Company on a lot owned by J. A. Giddings, situated within the corpo- 
rate limits of Jefferson. A record of this furnished by F. S. Jones, is as 
follows:

This well produced 7 barrels of oil the first hour and then dropped sud- 
denly to one and one-half barrels per day. Not long afterwards a well was 
drilled near this one with similar results. The oil has a gravity of 43 de- 
grees B. These are the only oil wells secured thus far (1901) in the 
county. 
In the spring of 1900 a well was drilled on land of George Hunter, 
two mile northwest of Jefferson. The base of the shale was found at 1,692 
feet, and the “gas sand” at 1,989. The well yielded considerable gas, the 
closed pressure rising to 830 pounds per square inch. Since that time nine 
additional wells have been drilled in that locality, and all contained gas. 
' According to F. S. Jones the closed pressure in these has is some cases 
exceeded 800 pounds per square inch. The daily production of the best 
wells has been about 2,500,000.cubic feet. As developed in 1go1 the field 
has a length of three miles and a width of one. Its direction is north- 
east and southwest. 
The sand has a thickness ranging from 30 to 4o feet. Gas is found in 
the very top, and just below lies a large reservoir of salt-water, which is 
constantly threatening the life of the wells. The Northeastern Oil and Gas 
Company has control of the territory, and supplies fuel to Jefferson, Ash- 
tabula, Geneva and Conneaut. ' | 
In the fall of 1900 a well was drilled on the Traverse farm, two miles 
north of Jefferson, but a showing only of gas was secured. Outside of the 
localities mentioned a few deep wells have been drilled. One on the
