JVa-i'crly Formations of Central Ohio. — Prosscr. 349 
8. Apparently two layers of yellowish sand- 14' 141' 
stone similar to the zone below with a shaly 
sandstone to shale a little above the middle. 
7. Massive stratum of yellowish, coarse grained 8' 127' 
sandstone, which is friable. 
6. Iron-stained S'Sndstone. irregular, somewhat 2' 4" 119' 
shaly. and contains pockets of shale. 
5. Light gray to bluish coarse grained sandstone. 
4. Sandstone similar to the zone above. 
3. Covered to base of quarry. 
2. Alternating shales and thin sandstones which 
are bluish at the base, becoming more iron- 
stained and coarser toward the top, shown 
along quarry road. Cuyahoga formation. 
I. Covered from school yard. 5' 5' 
In the above section the shales and sandstones of No. 2 be- 
long in the Cuyahoga formation, while the rocks from No. 4 
to the top of the quarry apparently belong in the lower part of 
the Black Hand formation. 
P'rom the^base of the Cross quarry to the base of the Berea 
sandstone on the southern l)ank of Little Walnut creek to the 
southeast of Waterloo the barometer gave a difference in ele- 
vation of 200 feet. The latter locality is one and one-fourth 
miles farther west than the Cross quarry while the dip in this 
region is about 20 feet per mile to the east. As the thickness of 
the Berea sandstone and the Sunbury shale at Lithopolis is 
33 feet it indicates that the Cuyahoga formation in this section 
has a thickness of about 2CX3 feet. Estimates made in other lo- 
calities in this general region indicate a thickness ranging froir. 
200 to 250 feet for the Cuyahoga formation. 
E.ASTERX FR.\XKLIX COUNTY 
In the eastern part of Franklin county near Blacklick and 
Reynoldsburg and on Blacklick creek are exposures of the 
lower formations of the Waverly series. This region has neither 
been very carefully described nor the formations in all cases 
correctly identified. 
Blacklick Creek and Ullage 
On the eastern bank of Blacklick creek a little above the 
Broad street pike crossing and one mile below the railroad 
bridge at Blacklick, is a good outcrop of the Sunbury ])lack
