ings ; the basal sandstone of the Cuyahoga

2. Upper part of shale zone gritty, below which it io'+ 12' 
is argillaceous and 4 feet below the top is a 
somewhat gritty and coarser band. The lower 
6 feet drab, soft argillaceous shale which is 
apparently without grit. 
I. Sunbiiry shale. Black fissile shale to bottom 2'.-i; 2' 
of the run. 
A few rods to the west is another run on the same farm, 
which flows southerly, on which a few yards above its mouth is 
shown eight feet of the upper Sunbury shale ; but none of the 
clay shale at the base of the Cuyahoga formation. A little far- 
ther up the run is another outcrop of the Sunbury shale under 
a clump of trees. 
About one and one-half (?) miles to the northeast of Rey-

Total 
No. Thickness, thickness. 
15. Rather thin bedded sandstones of light gray S'-f- 75' 
color, which on weathered surface are brown- 
ish gray or iron-stained, that alternate with 
thin layers of shale. Thickness 8 to 10 feet. 
14. Sandstone zone which is more or less solid. 3' 66'io" 
13. Olive shale. .8" 63' 10" 
12. Sandstones which weather to a brownish-gray g'^' ^2)2" 
or iron-stained color, alternating with shales. 
II. "Block layer" of quarrj'man from i foot 3 iV' 53'io" 
inches to I foot 6 inches in thickness, which 
stains badly on weathering and is not used. 
Shale parting. 
10. Bluish-gray sandstone. 
9. Blue shale. 
8. Bluish-gray sandstone. This and the sand- 
stones above discolor badly on weathering. 
7. Blue arenaceous shale. 
6. Probable top of Bueim Vista member. Three 
courses of bluish-gray sandstone, each one 8 
inches in thickness, which are fairly soft, and 
are sawed into flagging. These stmdstones do 
not discolor on weathering.
