and is by barometer ninety feet below Gambier. Near Brownsville, it is 
fifty-five feet, and south, at Millwood, ninety-five feet below Gambier. 
These facts indicate a pretty uniform dip of this rock to the south-east, 
and that it is a continuation of the coarse body of rock in the east part 
of Richland county. On the C., Mt. V. & C, Railroad, half a mile east of 
Howard station, a quarry belonging to Hurd & Israel has been opened, 
at an elevation fifty feet below Critchfield’s, of which the following is a 
section so far as exposed :

The lower stratum is a coarse stone with much iron, containing pock- 
ets of soft iron ore, in some places striped like the Mansfield stone, and 
in. others of a deep cherry red; general color yellow; fucoids the only 
fossils observed. 
Indian Field Run, a smali stream emptying into Owl Creek from Har- 
rison township, and occupying a rocky valley of recent erosion, gives 
fine exposures of the Waverly, where many of the layers are from three 
to four feet thick, but they contain many concretions or pockets of iron 
ore, and occasionally nodules of iron pyrites. Impressions of fucoids are 
here abundant. The general color of the rock is yellow. The valley and 
slopes are filled with the debris of the local rocks, with no indications 
of Drift except an occasional granitic bowlder. Near the top of the hill 
on the west, Drift bowlders are more abundant, and heavy masses of 
Drift cover the western slope descending toward Owi Creek. 
From thirty to forty feet of the bottom of the Waverly Conglomerate 
has argillaceous bands interstratified with the quartz-bearing beds of 
sandstone. Below this the mass of the material to the checelate shales 
is argillaceous, with frequent hard bands of calcareo-silicious rock, and 
occasionally strata of sandstone. One of the latter, No. 19 of the general 
section, is twenty-two feet thick, the upper part with argillaceous bands, 
the lower carrying quartz pebbles; another stratum, No. 21, one hundred 
and twenty-five feet below the last, is a very fine blue compact sandstone, 
bearing some resemblance to the finer grades of the Berea. It is not 
persistent, and in most of the hills its horizon is occupied by argillaceous 
shales. Indeed, all these thin beds of sandstone seem to disappear east- 
ward, the whole interval between the Waverly Conglomerate and the 
chocolate shale being filled with argillaceous shale. 
One hundred and fifteen feet below the hard blue sandstone mentioned 
above, a similar rock occurs eight and a half feet thick, the upper part 
dark colored. This is about on the horizon of the Berea grit, and it is
