also mined by Jacob Anthony and Eli Johnson, on Section 14, but the 
upper bench is wanting here, and the coal measures only 18 inches. 
The seam is also worked on Sections 12 and 13. ‘In fact, the seam is 
almost universal through western Starr-and eastern Washington, pass- 
ing into Falls and Green. It deserves a more careful investigation 
than it has yet received, though it is not probable that it will prove a 
safe basis for any considerable mining operations. 
The Mercer Coals. 
The two Mercer coals are persistent throughout the field, but the 
upper coal seldom exceeds 16 inches in thickness. The lower coal is 
mined, in default of a better seam, through parts of Falls, Washington, 
and Starr townships. <A third seam, known in Washington as the 
Price coal, seems to belong to this horizon, lying about 20 feet below 
the limestone. It is probable that this extra seam is of the same age 
as the Union Furnace block ore. It may be, however, the normal 
Lower Mercer seam, unusually separated from its limestone. The chief 
fact that implies another place for it is the presence of a sandstone in 
the interval in one case. 
The normal seam is well shown in the small mine of George W. 
Manks, on Section 31, Washington.

The seam is seen to carry a large amount of foreign matter, and of 
such a kind as to render steadiness and regularity out of the question. 
It is not often found in much better condition than this, but its phases 
are numerous. 
The seam, which has been already referred to as an abnormal 
phase, in some respects, of the Lower Mercer, is known in a few
