nowhere known at present where it can be profitably quarried in a large 
way. The Wolf quarry has not been worked for a number of years. 
The stone quarried for building purposes in Coshocton county is 
obtained from blocks detached from strata of sandstones of the Lower 
Coal Measures. The stratum from which the blocks quarried by the 
parties represented in the tables have been detached is a solid ledge 30 
feet in thickness, and lies a few feet above the horizon of the Zoar 
limestone. The material is usually a light-colored sandstone, though 
some of it has a reddish color, and some is a finer-grained white sand- 
stone. The stone used for the construction of locks on the Ohio canal, 
through Coshocton county, was obtained from these quarries. ‘The stone 
has the reputation of enduring well ordinary atmospheric influences, but 
not of withstanding a high degree of heat. It is principally used for 
bridge building and foundations in the vicinity of the quarries. 
Material for the ordinary purposes of construction is obtained in 
various localities in Muskingum county from the Coal-Measure sand- 
stones, but there is no extensive quarry at any place except about halfa 
mile east of Zanesville. This quarry furnishes by far the largest part of 
the stone used for construction in and about Zanesville. It has been 
used quite extensively for building canal locks, foundations, and for 
sidewalk pavements. Some of the oldest buildings in Zanesville are 
constructed entirely of this material, and it is found that the stone is 
more capable of resisting atmospheric agencies than of resisting the 
abrasive action to which it is subjected in sidewalks. This material is 
easily obtained in great abundance and of fair quality, and is the most 
important among the building stones found in the neighborhood of 
Zanesville. The most conspicuous use yet made of the stone is in the 
construction of the new Court House of Tuscarawas county. It has 
here been found susceptible of ornamentation to a marked degree. 
The most important building-stone quarry in Noble and Guernsey 
counties is near Cumberland, on the line between the two counties. The 
stratum quarried is solid and about 10 feet in thickness. The material 
is a dense, fine-grained sandstone, rather hard, but susceptible of being 
finely carved. It is of a gray or light-brown color where it has been 
subjected to atmospheric influences, but as the excavation progresses 
into the hill a material of bluish-gray color is obtained. Joints in this 
stratum are filled up with a hard calcareous matter deposited from solu- 
tions of the material from a limestone ledge a short distance above the
