JVavcrly Formations of CciUral Ohio. — Prosscr. 355 
The writer has ah-cady shciun lliat this (hvision is the same 
as the Berca sandstone/'' hence tlie correlations of the sand- 
stones shown in Taylors railroad cut are in harmony. The 
identification, however, of the rocks shown in the "section of 
Waverly sandstone at Armstrong's quarries, Blacklick sta- 
tion," f is erroneous. The writer has shown that the Waverly 
shales of tiie Franklin county report are the upper portion of the 
Bedford shales. $ 
The ten feet of Waverly shale, however, given at the hase 
of Dr. Orton's Blacklick section is not the top of the Bedford 
shale but the zone of soft shale at the bottom of the Cuyahoga 
formation which has been described in this paper at the expo- 
sures on Blacklick creek above the Broad street pike crossing 
and below the Presbyterian church in Blacklick. The overlying 
torty-eight feet, ten inches of sandstones and shales in this, sec- 
tion referred to the Waverly quarry system (=Berea sand- 
stone) instead of being the Berea belongs in the lower part 
of the Cuyahoga formation. Apparently this quarry is referred 
to the Berea grit in the Tenth Census ''Report on the building 
stones of the United States, and statistics of the quarry in- 
dustry for 1880," compiled from notes of Dr. Orton.i^ 
Reynoldsburg and Vicinity 
On the bank of a small run a short distance east of Rey- 
noldsburg, about opposite a street turning south, on the Sam 
Chamberlain farm is an outcrop showing the top of the Sunbury 
shale and the lower part of the Cuyahoga formation. The sec- 
tion is as follows : 
Total 
No. Thickness, thickness. 
4. Thin bedded, graj^ish sandstone with perhaps 4'+, I7?4' 
a shale zone in this interval; partly covered. 
3. Greenish-gray sandstone containing numerous i^'+ 1354' 
specimens of Spirophyton, which on weathered 
surface tends to split into thin layers but 
probably under cover it is massive. A loose 
block on the bank is i foot 9 inches in thick- 
ness, its top covered with fucoid (?) mark-
