and bottom surfaces appear to be uneven so 
that the thickness of the layer is variable.

The 12-inch zone of gray to blue and black shales between 
zones 6 and 12 of thick black shale shows the appearance of the 
gray to blue soft shale at a higher stratigraphic position. than in 
the sections toward the Lake Breeze House. For example, in the 
section on the Hill farm above the conspicuous sandstone zone are 
from 23 to 43 in. of blue, argillaceous shale and sandstone, and then 
the 11 ft. 5 in. of black shale extending to the top of the shale 
outcrop. In this section there are from 33 to 4 in. of blue shale 
above the conspicuous sandstone, then 4 ft. 10 in. of black shale 
overlaid by the 122 in. of gray to blue and black shale, capped by 
63 ft. of black shale near the base of which is a cone-in-cone layer. 
This upper zone of black shale, No. 12, certainly appears to belong 
in the Cleveland. 
Beach Park section.—In the western part of Beach Park, just 
west of the bathing beach, a marked anticlinal fold brings up the 
rocks for some thickness below the conspicuous sandstone layer, 
which at this locality appears at the top of the bank until it dis- 
appears toward the axis of the fold.
