Waverly Formations of Central Ohio — Prosser. 357 
3. Similar bluish-gray sandstone. 2'2"4;; 47'2" 
2. Bluish-gray sandstone (freestone of quarry- 3'4" 45' 
men) which cuts well. This layer and the two 
superjacent ones are sawed into flagging, win- 
dow sills, etc. This layer sometimes splits 
into two, the upper one 2 feet in thickness. 
Mr. Forrester considers this layer identical 
with the massive 3V2 foot layer (No. 10) in 
the Lithopolis quarry. 
I. Mainly covered down the stream to the top 4i'8'' 4i'8" 
of the Sunbury shale, with the exception of 
the section described on the Chamberlain 
farm. Mr. Forrester stated, however, that in 
one part of the quarry they went down 30 feet 
below the bottom of the quarry and found the 
rocks blue sandstones alternating with "soap- 
stone" (shale), but not valuable for quarrying. 
On the northern bank of the quarry, which is the old wall, 
it is twenty-six feet from the top of Xo. 6 to the top of the ex- 
posed rocks, or two feet and nine inches more than on the east- 
ern and newer wall of the quarry. This gives about 78 feet of 
rocks exposed above the top of the Sunbury shale all of which 
belong in the lower part of the Cuyahoga formation. It is to be 
noted that these rocks are the same as those exposed on Black- 
lick creek at Blacklick with more than twice the thickness of 
the entire Berea fonnation on Rocky fork, five miles north- 
west of this section. The change in lithology from the rocks 
referred to the Buena Vista member to the overlying ones is 
not so conspicuous as at Lithopolis ; but the line has been pro- 
visionally drawn at the top of the three courses of eight incli 
sandstones or No. 6. The sandstones of Xo. 6 and lower ones 
are bluish-gray from which there is a considerable change to the 
overlying grayish sandstones which weather to a rusty color. 
Tlie rocks, however, overlying the Buena Vista member contain 
a much larger proportion of sandstone than is found in the 
similar part of the section at Lithopolis. This section gives 
the Buena Vista member a thickness of fifty-one and tliree- 
fourths feet which agrees quite closely with the fifty-three and 
two-thirds feet of the Blacklick section and the forty-nine and 
one-third feet of the Lithopolis section. 
A well was drilled near this quarry, which, according to 
Mr. Forrester's record, began near the top of No. 6 and at a 
depth of forty feet reached what he called soft mud. This mud
