ide, which robs it of beauty, but interferes in no way with its durabil- 
ity. In all northeastern Ohio there is no limit to the amount of strong, 
massive, and durable building stone to be obtained. The quarries in 
the middle division of the Conglomerate series, on account of the more 
favorable situation of the outcrops, are more largely worked than the 
quarries in the upper and lower divisions. | 
The Austintown quarries have been worked at intervals since the 
country was settled. The stone is light-brown in color, rather coarse, 
but uniform in texture. It is used to some extent for purposes of orna- 
mentation in Youngstown, but its principal uses are for general build- 
ing purposes and bridge work. I lag-stones of fair quality are also 
quarried here for the local demand, from a horizon just below the sand- 
stone ledge. Blocks of any desired dimensions may be obtained from 
the middle division of this series, and the material is used principally 
for general building purposes, bridge work, and to a small extent for 
ornamental fronts. The principal market for all these quarries is 
Youngstown. Some material is shipped from the Briar Hill quarry 
to Pittsburgh and some is used for purposes of construction by the 
New York, Pennsylvania, and Ohio railroad. 
Stone for local uses may be obtained almost everywhere in Tusca- 
rawas, Holmes, and Knox counties, and for this reason no extensive 
quarry is worked. A quarry was opened and developed for the pur- 
pose of extracting material for bridge construction on the line of rail- 
road running near the quarry, but is now nearly abandoned, because 
this railroad obtains building stone in cuts through the same stratum. 
This stone lacks the uniformity of texture and color demanded for the 
better class of work. 
There are a number of ledges of sandstone, about 20 feet in thick- 
ness, found at different horizons in the Lower Coal Measures in Tusca- 
rawas county, and they all furnish some building stone. A consid- 
erable portion of the building stone used in the county is obtained 
from masses of rock which have been detached from the solid ledges. 
The stone from the quarry of the Tuscarawas Valley Coal and Iron 
Company is finer in texture and of a more uniform color than any other 
stone obtained in the county. It is used for “bottom” in the blast-fur- 
nace belonging to this company, and resists the action of heat uncom- 
monly well. The principal uses of the material from these quarries are
