These figures can be recognized as marking the Nelsonville type, 
but they show an inferior grade, especially in the high percentage of 
sulphur. 
There is good reason to expect somewhat better coal as well as 
a little more of it, in the territory to the north-east of Carbondale. 
It is asserted that in the entries running to the eastward in the Car- 
bondale mine, the coal strengthens perceptibly. It is probable that 
this thickening will be found to consist either in the restoration of the 
lower bench to its normal measurement in the Hocking Valley, or to 
an improvement in the quality of the top bench by which it becomes 
mineable, as at Hamley’s Run. 
This completes the account of the principal mines of the Hocking 
Valley in the Middle Kittanning seam of coal (No. 6 of Newberry). 
The condition of the seam in Starr township, Hocking county, 
will also be briefly considered here. There are no shipping mines in 
Starr, but the thickness and quality of the coal are so often made 
the subject of inquiry, that the facts that are in hand will be given, to 
meet as far as they may, such questions as arise. 
Quite an area in the eastern part of Starr township is credited 
upon the map with holding 5 feet or more of coal in this seam, This 
area is chiefly confined to Sections 1, 2, 3, 4 and 7. Throughout 
most of it the seam is under heavy cover, and our knowledge of its 
condition is fragmentary and imperfect. The Lick Run coal is followed
