806. _ GEOLOGY OF OHIO. 
In comparing this section with that taken on the south side of the 
river, we find the following differences: 
Ist. A coal seam three feet beneath the Lowell Limestone, not seen on 
the south side of the river. 
2d. The interval between the Lowell Limestone and Coal No. 8a dimin- 
ished nearly forty feet. 
8d. But one thin coal over Coal No. 3a. 
4th. The limestone wanting. 
5th. The coal thickened in places to four feet two inches, and the only 
workable seam on this side of the river. 
6th. Coal No. 3 diminished to two feet, and of no value. 
Coal No. 3a is here a good cementing coal, which has furnished consid- 
erable coke, used in the Lowell Furnace. It is mined on the farm of 
Lowerly and McClintock by Johnson, Brown & Co., where it consists of 
two benches of cementing coal, with a parting four to six inches from 
the top, and a third bench of cannel six inches thick at the bottom. 
In the southern part of Poland township, as in most of Springfield and 
Beaver, the surface is covered with Drift, and the geology is concealed. 
On Section 30, of Poland, a coal seam is opened, which is apparently No. 
4. Jt is thirty inches thick, and of good quality. In the eastern part of 
the town, coal is mined at Park and Lowe’s slope, and on the farm of 
Samuel Hines. This is apparently above the Lowell Limestone, and yet 
would seem to be the same coal as that last mentioned, and as that mined 
by Azariah Paulin in the north part of Beaver, which is, unquestionably, 
Coal No. 4. 
SPRINGFIELD. 
In Springfield, coal has been opened at a great number of localities, 
but is nowhere largely worked. If we are not mistaken in its identifica- 
tion, all the mines are in Coal No. 4. These are: 
1. ‘Somers’ bank,” on Jacob Kurtz’s farm, Section 4, coal thirty inches 
thick, of good quality, the top somewhat open-burning. 
2. Thomas Dyce’s bank, on the Reaulman farm, Section 15, coal two 
feet nine inches, cementing, and much esteemed for blacksmith’s use ; 
limestone and iron ore reported below it. 
3. McGill and Livingston’s mine, on the farm of J. Egerts, Section 24, 
coal twenty-seven to thirty inches thick, in two benches ; the upper (can- 
nel) one foot nine inches; the lower (bituminous) six inches thick. 
4, Chris. Beck’s bank, fifty to sixty rods south of No. 3, coal twenty- 
six inches thick—all bituminous. | 
5. Jeremiah Brown’s farm, Section 8, coal thirty-eight to forty inches,
