716 ANNUAL REPORT 
barrels per day. It was still producing in August, 1902. The fact that 
just across the road from the Kirkbride very small wells were secured 
has given rise to the belief that the great well was of the crevice type. 
The life of the wells corresponds to that found in adjacent counties. 
Those in the so-called barren tract, as has already been stated, are soon 
abandoned; but those in better territory produce much longer. In fact, 
it is doubtful if the maximum life of a well in this county has yet been 
determined. The oil ranges from 38 to 39 deg. B. in gravity. 
Salt-water.—This has been found in all parts of the county, but the 
quantity has been smaller than in Wood. Nowhere does the brine seem 
to have been a serious obstacle. Sometimes a small quantity has been 
found in the Clinton, but here as elsewhere the great volume has come 
from the Trenton. 
SENECA COUNTY. 
Lying east of Hancock county, and containing the two progressive 
cities Tiffin and Fostoria, it was very natural that the underlying rocks of 
Seneca county should be tested early. The results of these explorations 
have already been outlined: Fostoria never secured the desired gas, 
though she later obtained a supply from Wood county; and oil too was 
denied her. ‘Tiffin was a little more fortunate, securing a small quantity 
of both products. 
Developments during the past fifteen or sixteen years have done very 
little for the county, though the rocks have been extensively tested. The 
only productive territory is found in the northwestern corner, and around 
Tiffin. 
Hopewell and Clinton Townships.—This includes the Tiffin pool, 
having a length of four miles and a width not exceeding one and one- 
half miles. By far the greater portion of the territory lies in Clinton 
township, a strip a few hundred yards wide only extending into Hopewell. 
The first well was completed in January, 1886, and made a showing 
of oil, gas and sait-water. After having been shot with rack-rock it - 
was put to pumping, and yielded a small quantity of oil for several vears. 
Well No. 2 drilled the same year, was located about one mile west of 
No. 1, and found the Trenton rock 120 feet lower than the latter well. 
After having been shot this well flowed from 8 to 15 barrels of oil per day; 
it continued flowing until 1900 when it was put to pumping; in July, 
1902, it was still numbered among the producers. These results gave rise 
to much excitement, and led to extensive leasing of land in the vicinity of 
Tiffin. Several additional wells were drilled in 1887, but the results did 
not meet early expectations, and matters became quiet until 1892. 
During that year a large number—perhaps two score of wells were 
drilled along the banks of the Sandusky river, many of them in the heart
