was probably the shale zone at the base of the Cuyahoga for- 
mation in which case the well record of forty feet from the top 
of the Buena Vista member to the shale agrees closely with the 
forty-one and three-fourths feet of the above section. Below 
the soft shale the well passed through black shale and then en- 
tered sandstone to the distance of two feet. The distance from 
the top of the soft shale to the top of the sandstone, according 
to Mr. Forrester, is 20 feet and the sandstone below the black 
shale is apparently the Berea grit. 
SECTION SOUTHEAST OF NEWARK 
Investigations made during the last two years have changed 
considerably my ideas regarding the lower limit of the Black 
Hand formation, as exposed to the southeast of Newark, and 
the results will now be briefly stated. 
The following section is compiled from outcrops in Havens* 
quarry, down Quarry run to Licking river, the first run to the 
east and the cliff farther east near the house of Mrs. Mary M. 
Stasel which is one and one-fourth miles east of the Court 
House in Newark :

10. Alternating shales and sandstones to the tcp 14' I755^' 
of the east wall of Havens' quarry. 
9. Fairly massive bufiF sandstones. 16' 161^' 
8. Bluish shales; base of Logan formation. 5' 145V2' 
7. Top of Black Hand formation. Grit stratum i' 140^^' 
varying in thickness from 10 to 13 inches. Con- 
glomerate II of Herrick. 
6. Allorisma shales. "'4" I39'6" 
5. Massive buiif freestone, lower part thin bedded 28'6" I32'2" 
to shaly layers. 
4. Rather coarse quartz pebble conglomerate 3'8" I03'8" 
which varies in thickness. Conglomerate I of 
Herrick. In the run below Havens' quarry 
3 feet 8 inches is clearly shown, although the 
thickness is somewhat greater (4 feet 11 
inches in a former measurement when it was 
exposed to better advantage). On the Stasel 
cliff buff sandstones alternate with layers of 
grit and conglomerate with a thickness of 
about 7 feet 11 inches of which the following 
is a detailed section :
