280 GEOLOGY OF OHIO. 
Opposite the mill of Mr. McFarland, Mr. Landon owns another quarry, 
situated a little further down. At this place the exposed section is as 
follows, continuing the numbering from above:

The shale of No. 12 is apt to contain thin but very even beds of good 
sandstone. Indeed, one heavy bed of sandstone, valuable for railroad 
bridges, and for that purpose here quarried, entirely embraced in this 
shale, gradually thins out horizontally toward the north, and disappears 
entirely in the distance of 22 feet. This is a valuable quarry and furn- 
ishes heavy stone. The same is true of Sprague and Burr’s quarry, 
which is across the creek and near the mill of Mr. McFarland. It is in 
the beds of No. 11 of the foregoing section. 
Passing dowr the creek to the mouth of the Rattlesnake Creek, no 
further view of the shale underlying the sandstone is obtained. The 
bluffs are bold and rocky on either side, large fallen masses lying at the 
base, breaking the force of freshet currents and concealing the shale 
from sight. : 
The foregoing section of the lower portion of the sandstone, Nos. 1 to 
16 inclusive, includes the Berea grit. It shows the imperceptible change 
that takes place between the Cuyahoga and the Berea. There seems 
to be no marked horizon setting off one from the other, yet there is a 
lithological difference that mainly consists in the heavier beds and the 
coarser grain of the Berea. The mica specks are also wanting generally 
in the Berea, although it is probable they would be found in the inclosed 
shale. The Berea may be said to include Nos. 8, 9, 10, 11, 18, and 15; the 
Cuyahoga would embrace Nos. 1, 2, 3, 4, 5, 6, and 7. The underlying 
shale is represented within the sandstone layers of the base of the Berea 
grit by Nos. 12 and 14; showing a gradual transition, so far as this sec- 
tion is concerned, from shale to coarse-grained sandstone, and then to 
the fine and shaly beds of the Cuyahoga. The very rough and tragment- 
ary condition of Nos 8 and 10 should be specially noted. It occurs within 
the Berea, and has not been seen elsewhere in that formation. 
Berea Grit.—Besides the foregoing sections in the Berea grit, it is also 
quarried by Mr. John Knox, in the banks of the Rattlesnake Creek,
