of paralellizing the conglomerate I. at the Dug-way, (or the first of the 
above mentioned stations) with the second conglomerate at the south 
Newark quarry, thus making the combined Waverly section too small 
by 39 feet. In like manner a level (barometric) between Granville 
and Cat run, a distance nearly due north of 5^ miles, reveals a dip 
to the south along congl. I. of 79 feet, or over 14 feet per mile. The 
section at this place is 
4. Freestone and part of shale below congl. I. 35 ft. 
3. Shales and freestone 29 ft. 
2. Congl. I, coarse pebbles, loose __i6 in, 
I. Shales with Palaeoneilo attenuata 14 ft. 
The relations are almost precisely as at the Dug-w'ay. Passing 
southwest from Granville, a distance of three miles, at Cheney’s run, 
we find, at the bottom, a fossiliferous band marking the horizon 40 ft. be- 
low conglomerate I. This is about 30 feet higher than at Granville, a dip 
of only 10 feet per mile. Now passing due west to a point 4^ miles 
west of Granville, the bridge over Moot’s run is reached. At this 
place a fossiliferous layer of shale is found 36 feet higher than the last 
mentioned, which would permit this horizon to be identified with the 
40 ft. layer above mentioned assuming a dip of 12 feet per mile to the 
east. There are, however, at this place indications of a local increase 
in dip, and this layer contains Spirifer marionensis and few fossils iden- 
tified in the 40 ft. layer farther east, while 20 feet above are layers 
with the lithological character of that horizon (unfortunately unfossil- 
iferoLis. ) At the foot of this exposure, 20 feet below the Sp. marion- 
ensis layer, are found specimens of Chonetes logani 2iwdi Rhynchonella 
sappho. Passing one mile west, a very interesting bed of shale with 
limestone nodules is exposed. This bed is very fossiliferous and is the 
lowest richly fossiliferous bed known in the Waverly. This is thirty 
feet above the Spirifer marionensis layer and, allowing a dip of 15 
feet to the mile, would still lie at least 15 feet above that horizon strat- 
igraphically. It probably is upon nearly the same horizon. Contin- 
uing west twelve miles to Rocky fork, a series of gritty flags and shales 
is reached about 15 feet higher than at the Sp. mai'io^-ensis layer at 
Moot’s run, by barometer; thus, allowing a dip of 14 feet per mile, we 
reach a horizon about 1 70 feet below that layer. At a point three or four 
miles farther west and south, not far from Gahanna, these gritty lay 
ers are quarried and are interspersed with layers of bituminous shale 
like the Ohio black shale. A point quite near the foot of the Waver-
