these townships. The great seam at present monopolizes attention and 
overshadows this upper seam, which would be elsewhere counted an 
excellent basis for mining. 
In Section 8, York township, near Floodwood, a new mine has 
recently been opened in this seam by the Hamilton Coal Co. 
The structure of the seam is shown in the appended figure :

The measurement was taken before the entry was driven far under 
the hill, but it fairly represents all of the subsequent workings. The 
coal mines rather small. An effort is now making to improve the size 
by using slower powder. The product of the mine is almost exclusively 
used as a steam coal. The seam now under consideration occurs at 
very many points throughout the territory that has been traversed. It 
has occasionally been opened in the small way for farmers’ banks, but, 
as a rule, it can be judged of only by its natural outcrops. While un- 
steady and uncertain, there is no doubt that it makes a very valuable 
contribution to the fuel resources of the Hocking Valley. 
In Waterloo and Athens township this coal was mined for many 
years on the line of the Marietta Railroad, where it was known as the 
DeSteiguer coal. The workings have been abandoned for several years. 
The Lower Freeport and also the Lower Kittanning coal are occa- 
sionally opened and worked in the smallest way in the Hocking Valley.
