THE LOWER COAL MEASURES. 229 
These analyses show that the Palmyra coal in its best condition is 
one of the finest coals of the State, in no respect inferior to the best 
mines of the Mahoning Valley. The cannel seam of the Scott bank 
was éarefully examined to see if any portions of it rated higher than the 
rest. It is poorest in the middle, but the top and bottom of the cannel 
are fairly good representatives of that variety of coal. 
This completes the account of the coal output of Portage county. 
Formerly a little poor coal was mined about Atwater. It probably 
belonged to the Mercer horizon, but nothing is now done in this field. 
The clays of the horizon are extensively worked. 
V. COAL MINES OF STARK COUNTY. 
As in the case of the counties already treated, the geology of Stark 
county has been given with considerable detail in the excellent report 
of Newberry, in vol. III. The discussion of the Massillon coal in the 
report is particularly full and valuable. Aside from the correction of 
the general section, the present report will be mainly confined to the 
more recent developments of the coal seams of the county. 
GENERAL SECTION. 
As already shown, there is in Newberry’s report a double use of 
the numbers 5 and 6 in the southeastern corner of the county (see p. 69), 
but this error applies to but a small territory, and by far the larger part 
of the county falls within the limits of a section in regard to which 
there is no dispute. The main elements of the geological scale of Stark 
county are as follows: 
22. Mahoning sandstone, coarse and sometimes pebbly. 
21. Upper Freeport coal, passing into Blackband ore at many points (No. 7 of 
Newberry). 
20. Upper Freeport clay. 
19. Upper Freeport limestone. 
18. Upper Freeport shale and sandstone. 
17. Lower Freeport coal (No. 6a of Newberry). 
16. Lower Freeport limestone. 
15. Lower Freeport sandstone, often pebbly and massive, and reddish in color. 
14. Middle Kittanning coal (No. 6 of Newberry).
