its economic values are limited mainly to the elements previously named.

The Sub-Carboniferous limestone has its best development in Ohio, 
in Perry and Muskingum counties. In Hopewell township, near Glen- 
ford, it has been worked for the Shawnee furnaces on a number of farms. 
Thence, eastward, along the valley of Jonathan’s Creek, there are 
frequent exposures of it, until, near Uniontown and Newtonville, we 
find not less than 20 feet in the bed and walls of the creek. Itisa 
very fine-grained homogeneous stone, sparingly fossiliferous, generally 
drab or light-buff in color, and, when skillfully worked, a building 
stone of great beauty and excellence. It has been employed to good 
advantage in Zanesville, in the construction of the new Court House 
and also in the new Opera House front. | 
The Sub-Carboniferous limestone is sometimes overlain by the 
Carboniferous Conglomerate and sometimes by the ordinary strata of the 
Lower Coal Measures. The Conglomerate is found in its best develop- 
ment in Hopewell township, where its maximum measurement is 60 
feet. It carries pebbles in large quantity, and in places a few feet of it 
are pure enough to furnish a glass sand of approved quality. It is now 
quarried and crushed for this use by J. Downerd and Son, at Chalfant’s 
Station. 
As usual, this stratum is exceedingly inconstant and irregular. 
Aside from the township named, it makes no appearance in the 
geological series of the county.

The Lowest Coals. 
The Sharon coal horizon is often marked by a bed of black shale 
lying above the limestone, but no deposit of coal of any value has been 
found at this level, and in none of the records of the borings made for 
salt or oil in the county has any deep coal ever been reported. A 
single exception may be needed for a tract of 25 to 30 acres on the 
farm of W. B. Taylor, Sect. 14, Hopewell township, in which a workable 
coal was found just above the Sub-Carboniferous limestone. So far as 
can be judged from all the facts of the outcrops of these lowest horizons, 
the Sharon coal is not likely to be found in Muskingum, Perry or 
Hocking counties, in valuable condition, and no really workable bed of 
the Quakertown coal (No. 2) is known in these limits. The latter is
