BUILDING STONE. 583 
At East Cleveland the: Berea grit becomes 60 feet in thickness; 
and? although it does not possess all the desirable qualities of the 
Amherst and Independence stones, the Cleveland architects prefer it for 
foundations on account of its superior strength and its accessibility. It 
has not been used for any important superstructures in the city, the more 
excellent stone, before mentioned, being so readily supplied to this point. 
The Brooklyn quarries, which are situated just to the south of 
- Cleveland, produce a material which is of about the same quality as that 
found in the Kast Cleveland quarries, but the rock is more broken, and 
is used mostly for foundations and underpinnings. Its broken character 
allows it to be easily quarried, but large blocks are not so readily 
obtained. | 
The largest sandstone quarry in the county is situated in Berea, 
where an immense amount of material has been extracted for building 
purposes and for small grindstones. Nearly 40 acres of the Berea grit 
have here been quarried out to an average depth of about 40 feet. The 
stratum is from 65 to 75 feet in thickness, and has been quarried to the 
bottom in but few places. The individual sheets are from 2 inches to 
10 feet in thickness, and usually are very even in their bedding. The 
rock all lies below drainage level and seems to have been but little, if at 
all, disturbed since its deposition. Joints very seldom occur. ‘The 
stone is usually soft in the quarry and is very easily channeled. It is 
of a blue-gray color and a little darker as a rule than the Amherst 
“blue-stone.” A larger portion of the formation here is of the so-called 
“ split-rock” character than at any other locality where it has as yet been 
quarried, and this characteristic is also more perfectly developed here: 
than anywhere else. 
The material is not so applicable for the manufacture of large grind- 
stones as is that obtained in Lorain county, or at Bedford and Inde- 
pendence in this county. Small grindstones can, however, be manufac- 
tured more cheaply at Berea, because the rock can be split into thin 
slabs of any desired thickness with little or no waste. The manufacture 
of whetstones is also quite extensive. 
These quarries produce building stones of an excellent quality, 
although great care must be taken in the selection of the material, as 
some of it contains sulphide of iron in such amount as shortly to disfigure 
the surfaces, even discoloring a portion of the wall below it. The mate- 
rial is, however, carefully graded in such a manner as to distinguish the
