apparently included the Sunbury shale in the Orangeville 
shales.’ 
After the above was written the writer learned that a test 
well was being drilled in Orangeville, Ohio, and he is indebted 
to Messrs. W. J. Apthorpe and J. D. Burnett, of that town, for 
information concerning it and samples of the drillings. The 
mouth of the well is in the creek valley above the State-street 
bridge, estimated as about 6 feet higher than the milldam, 
which would make it about 1o feet higher than the base of the 
shales exposed on the creek bank below the dam. It is reported 
that the creek alluvium is 17 feet thick in the well and at that 
depth shale was struck. The first sample submitted to the 
writer, from the depth of 42 feet, is reported as the first sand 
struck in the well and from the top of the Berea grit. The 
sample is composed mainly of light-gray silicious and very 
micaceous sandstone, with an occasional grain of iron pyrites, 
and lithologically closely resembles the Berea grit. Mixed with 
the sandstone chips is an occasional one of black shale, which ts 
evidently from above the sandstone. This light gray sandstone 
is reported to continue to 122 feet,and a sample from 50 feet 
and another from between 57 and 117 feet are froma light gray, 
very silicious sandstone. The sample from 117 to 122 feet is 
composed of fine light gray to white quartz sand with some 
grains of iron pyrites and its bottom is thought by Mr. Burnett 
to represent the base of the Berea grit. Immediately below this, 
Mr. Apthorpe reports 3 feet of shale; but the sample from 122 
to 164 feet is composed mainly of quartz sand. Mr. Burnett, 
however, reported that at 122 feet the drill entered a softer 
sand. The sample from 164 to 170 feet is composed of bluish 
argillaceous shale with a white streak and bluish-gray or gray 
arenaceous shale to thin micaceous sandstone. From 170 to 
41s feet, the chips are mostly dark gray in color and apparently 
mainly from arenaceous shale. The data furnished by this well, 
1 Second Geol. Surv. Pa., Q*, p. 90 f., where it is stated that “here also it 
[Orangeville shale] is darker and even some thin layers bituminous, which goes to 
support Professor Orton’s identification of it with Professor Andrews’s Waverly black 
slate of southeastern Ohio.”
