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 VVaverly 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. 'I'he 

 section at this place is

The relations are almost precisely as al the Dug-way. 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 teet higher than at Granville, a dip 

 of only 10 feet per mile. Now passing due west to a point 4'j miles 

 west of Granville, the bridge over Moot's run is reached. .\t 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 |>cr mile to the 

 east. There are, however, at this place indications of a local increase 

 in dip, and this layer contains Spirifcr marioncnsis 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- 

 iferous. ) At the foot of this exposure, 20 feet below the Sp. marion- 

 ensis layer, are found specimens of Chonctcs logani and Rhvnchoftella 

 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 Waverlv. 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 hori/on 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 .S/. marionensis layer at 

 Moot's run, by barometer; thus, allowing a dij) 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 intersi)ersed with layers of bituminous shale 

 like the Ohio black shale. A point quite near the foot of the Waver-
