Bb. COALS. 
The analyses of two seams of coal from the district will conclude this 
list. The first one is Coal No. VIa, from lands of the Hamden Furnace 
Company, Vinton county. The coal lies in three benches, as does Coal 
No. VI. At the time of the analysis this seam was supposed to be the 
Nelsonville coal. It lies seventy-three feet above the Gray Limestone. 
It was afterwards shown, however, that the Nelsonville coal was present 
in the section, though in rather small volume, at forty-three feet above 
the limestone and the Hamden Furnace coal, as the present seam may 
be designated, was proved beyond question to be No. VIa. It will be re- 
‘membered that for a large area here the last named coal is much more 
important than the Nelsonville seam.

The second series of analyses is of the great seam (No. VI) in its best 
development at Straitsville. The samples were furnished by Moss and 
Marshall, proprietors of Bessie Furnace. They were taken from the 
mines of the Straitsville Mining Company—J. S. Doe and Co., lessees, 
upon the coal of which the furnace was then running. A diagram is
