From the exposition (p. 59) it may be seen that one may 
reasonably expect to find about 2000 feet of stratified rock, 
plus or minus 500 feet, below the bottom of the Coal Meas- 
ures and above the fundamental granites or gneisses. In part 
we know what the upper portion of this 2000 feet is like, as 
numerous deep wells have penetrated it to various distances. 
It is probable, also, that the uppermost part of the Mississip- 
pian as exposed at Galena to the west, where protected from 
erosion by the overlying Coal Measures in the oil-fields, is 
younger than that exposed at Joplin and further east, for re- 
cent erosion may have removed a very considerable portion of 
the upper Mississippian in that region. From paleontologic 
evidence it seems that the uppermost rocks at Galena belong 
to the Keokuk or younger formations which overlie the Bur- 
lington. 
Deep wells have been drilled at Neodesha, Caney, Cherokee, 
Stone City, Girard, Weir City, Iola, and a number of other 
places, records of some of which are here included, with plates 
or figures made from the drawings of the same. One is at 
Cherokee, Kan., 908 feet deep, which struck the top of the 
Mississippian limestone at 352 feet and therefore went 556 
feet below its surface; one at Stone City, a few miles south- 
west of Cherokee, with a total depth of 856 feet, which struck 
the top of the Mississippian at 376 feet and therefore went 
480 feet beneath its surface; one at Weir City, which went 
210 feet below the upper surface of the Mississippian; one at 
Girard, with a total depth of 900 feet, which struck the Mis- 
sissippian at 450 feet and therefore went 450 feet beneath 
its upper surface; and one at Neodesha, with a depth of 2412 
feet, struck the Mississippian at 1090 feet beneath the surface 
and therefore went 1322 feet beneath its upper surface. 
This latter well record is important because more care was 
given it than is given the ordinary well. It was drilled by 
the Forest Oil Company as a test well, and was begun almost 
immediately after they purchased the Neodesha oil properties 
from Guffey & Galey. This is the same company which drilled 
the Bedell deep well in West Virginia some years before, 
which well still remains the deepest boring on the American 
continent, having reached a total depth of 5575 feet. Mr. 
Patterson, still with the company, had immediate charge of the 
well and kindly kept duplicate sets of the drill-cuttings, one 
of which is preserved in the office of the Prairie Oil Com-
