WAVERLY SERIES OF CENTRAL OHIO 2 09 



sandstones in northern central Ohio in Crawford, Morrow, and 

 Delaware counties. 1 This identification of Professor Winchell's 

 is important because it carried correctly, for the first time, the 

 Berea grit with the overlying Cuyahoga shale from northern Ohio 

 to the central part of the state. Dr. Orton published the 

 descriptions of the geology of Pike and Ross counties in this 

 volume, and gave the following subdivisions of the Waverly 

 series : 



At the base are from 80 to 100 feet of the Waverly shales, 2 a 

 name apparently proposed by him. This was followed by what 

 he termed the Waverly Quarry System, with a thickness of 32^ 

 feet, one mile south of Jasper. 3 Immediately above the sand- 

 stone is a black shale, from 16 to 27 feet in thickness, which, 

 Dr. Orton stated, had been "designated by the chief geologist 

 the ' Cleveland shale ' and by Professor Andrews the ' Waverly 

 black slate;'" * while the remaining part of the series, including 

 everything "above the Waverly black slate and below the Car- 

 boniferous series " was denominated the Upper Waverly, com- 

 posed of shales and sandstones with a maximum thickness not 

 exceeding 425 feet. 5 



Meek in 1875, in giving the horizon of Discina (Orbiculoided) 

 Newberryi Hall, stated that certain specimens came "from the 

 Berea shale, a member of the Waverly group of the Lower Car- 

 boniferous," 6 which is, apparently, the first usage of the name 

 in a stratigraphical sense, although it does not clearly appear 

 that Meek intended to separate the shale from the subjacent 

 Berea grit. 



In 1878 Dr. Orton's " Report on the geology of Franklin 

 county" was published, and in it occurs a description of the 

 Waverly group as far as represented in the county. The Huron 

 shale, the youngest formation of the Devonian system, was 

 described as closing with "a red or chocolate-colored band, from
