has not been shown because of drift-covered outcrops or its occur- 

 rence below drainage, but it is probably present. Followed west- 

 ward from the Toboso province it can be traced readily into the 

 Conglomerate I of Herrick in the section in Quarry Run at Newark. 

 At the Dugway three miles west of Newark, where the Black Hand 

 member is largely shaly, the Berne member is lo feet thick and the 

 pebbles are noticeably smaller than to the eastward. 



The section in the Quarry Run at Newark has become the classic 

 section of the upper Waverly of Ohio. Prosser's description of this 

 section^ in which he adopted the stratigraphic units used by Hicks^ 

 and Herrick has been accepted as the standard column of the upper 

 Waverly, and most of the correlations that have been made with 

 the upper portion of the Waverly have been based thereon. It is, 

 indeed, the only section of this portion of the scale which has been, 

 accurately described. It appears, however, that the Black Hand 

 has been made to include too much in the descriptions of this 

 section. Only the lower 60 feet are the equivalent of the Black 

 Hand as that member is interpreted in the present work. Con- 

 glomerate I of Herrick, which was placed by Prosser 29 feet below 

 the top of the Black Hand, is the Berne member and the top of 

 the Cuyahoga. These 29 feet are to be correlated with the Byer 

 member and the lower part of the Allensville member of the Logan. 

 Prosser's error is the result of his having accepted Hicks's statement 

 that all of these beds were the equivalent of his (Hicks's) Black 

 Hand at Clay Lick and Toboso. To Hicks belongs the credit of 

 having first appreciated the passage of the Black Hand conglom- 

 erates into finer-grained sediments to the westward. If Orton had 

 appreciated the significance of Hicks's discovery, much of the con- 

 fusion of later years would have been spared.
