3. This interval down Quarry rini is mainly 60' lOo' 
covered, except at the base where 1 1 feet of 
massive buff sandstone is shown. In the first 
run east, however, 21 feet of buff rather coarse 
grained sandstone is shown at its base and on 
the Stasel cliff about 35 feet of similar sand- 
stone directly underlies Conglomerate I. Sev- 
eral barometric readings give the difference in 
elevation from the base of the coarse grained 
sandstone on Quarry run to the base of Con- 
glomerate I on the same stream as from 55 
to 65 feet, so that the rocks for the greater 
part of this interval are shown. 
2. Top of Cuyahoga formation. Mainly bluish- 304-/ 40' 
gray arenaceous and argillaceous shales with 
some alternating layers of sandstone which are 
occasionally a foot or more in thickness. On 
west bank of Quarry run there is a buff sand- 
stone stratum i foot 7 inches in thickness. Fos- 
sils occur in this part of the formation. The 
lowest shales are exposed in the bed of the run 
just above Summit street bridge.

In the above section the Black Hand formation has a thick- 
ness of lOO^S feet. When my former paper was written the 
Stasel cliff and coarse sandstones in the two runs to the west 
had not been seen by the writer and it was supposed that 
shales occurred directly below Conglomerate I as had been de- 
scribed by professor Herrick for the Newark region."^ Hence 
the base of this conglomerate was regarded as the base of the 
Black Hand formation. t The present section shows that to the 
east of Newark, coarse grained buff sandstones extend for
