lower coal, the Middle Kittanning coal is found for the last time in 
this field. It has been mined here in years past. It is from 24 to 34 
feet thick, and the quality is reported as fair, hut the roof is poor and 
mining has therefore been abandoned. It is 363 feet above Lake Erie 
at this point. . 
Crossing the county line into Carroll county, we find within 14 
miles of Moughimon’s Mills, the Dell Roy coal opened and worked in 
an unbroken chain of mines. ‘The first that we reach is the Bartholo- 
mew coal bank. It is 108 feet above Connotton or 446 feet above Lake 
Erie. The Kittanning coals have been carried below the bed of the 
creek by the dip which we have thus far followed. 
The relations of the Pike Run coal to the Dell Roy coal, both of 
them known as No. 6 in the State series, can be seen by the foregoing 
facts. The Kittanning coals, viz., the Mineral Point and Pike Run, have 
fallen to the level of Connotton at the Carroll county line. The Dell Roy 
coal at its first appearance in this line of sections is 108 feet above Con- 
notton, and more than this distance above the Middle Kittanning coal. 
The Lower Freeport coal is found at Dell Roy, 25 feet below the 
main seam. It is but 18 inches thick, and is described as highly 
cementing in character. 
This section is seen to confirm in all respects the conclusions drawn 
from the coals of the Sandy Valley and Columbiana county. 
It may be added that the Freeport horizon is further attested by 
its limestones which almost constantly accompany the coals. 
The Upper Freeport coal at Dell Roy is about 100 feet above Con- 
notton water. The entry of Empire Mine No. 2 is 459 feet above 
Lake Erie. The seam falls slowly to the southward, as can be seen by 
the closely connected openings up the valley of the Connotton. At 
Sherrodsville (New Hazelton) the coal is 409 feet above Lake Erie. At 
the point above Sherrodsville where the Wheeling and Lake Erie Railroad 
crosses the Connotton, the coal is 397 feet above Lake Erie, The 
Lower Freeport coal is also opened here at 51 feet below the upper 
coal. 3 
The Upper Freeport coal has been worked at Smith’s Mills, 2 miles 
further up the stream, and on every farm in the interval on the east side 
of the creek. It lies nearly level in the direction of the valley for a 
few miles. It is worked quite extensively at Leesville (Leesburg), and 
attains its highest quality here. At Bowerston it is mined for local use,
