length of four miles and a maximum width of two miles. 
Discovery and Development—In the winter of 1895-6 a well was 
drilled on the Delaplaine farm in section 11, near the village of Graysville. 
It made a good showing of oil in the Keener sand, but not sufficient, in the 
judgment of the drillers, to warrant shooting, and so the well was aban- 
doned.. However, the test was not regarded as conclusive, and accordingly 
a second well was soon begun, but this made a poorer showing than the 
first one, and so was abandoned without having been shot. A third well 
was completed on the same farm in December, 1897, with results entirely 
similar to the preceding two. These failures discouraged further explora- 
tion, and nothing more was done until 1900, when the Devonian Oil Com- 
pany drilled a well on the same farm and about 75 yards from the first well. 
This well was completed in June, and after having been shot with 100 
quarts of nitro-glycerine began flowing oil, producing at first nearly 100 
barrels per day. The producing sand was the ‘Keener. About one month 
later a well was drilled on the Eaton farm, adjoining the Delaplaine on 
the north. This was a success, though not so good as the one previously 
drilled. These two wells attracted the attention of operators in other 
fields, and soon the territory was being rapidly developed. The boom 
lasted during the summer and fall of 1900, but since then comparatively 
little work has been done. This has resulted partly from the decrease in 
price of oil, but more largely from the diminution in the size of the wells 
as the drill moved farther and farther from the center of the productive 
territory.
