IV A VERLY SERIES OF CENTRAL OHIO 21 I 



In July 1878 Professor L. E. Hicks, of Denison University, 

 announced "the discovery [of] an unmistakable outcrop of 

 Cleveland shale [which] exists two miles east of Sunbury in 

 Delaware county, southern [central] Ohio, on the land of 

 Horace Whitney. It lies above the calcareous sandrock of the 

 Sunbury quarries, which Professor N. H. Winchell, a special 

 assistant of the Ohio geological survey, identified as Berea grit. 

 My discovery demonstrates the incorrectness of that identifica- 

 tion, and raises a strong presumption, amounting almost to a 

 certainty, that he was equally wrong in respect to his Berea grit 

 in Morrow and Crawford counties." 1 Professor Hicks made no 

 reference to the classification of the Waverly and identification 

 of the Cleveland shale in Franklin county by Dr. Orton, and on 

 the other hand Dr. Orton did not mention Professor Hicks' 

 papers in any of his publications so I am unable to state which 

 article has priority. The September number of the same peri- 

 odical contained. a classification of the Waverly group in central 

 Ohio by Professor Hicks, which was stated to include the rocks 

 lying between the Huron shales and the base of the Coal- 

 measures. The classification is as follows : 



Feet thick 



5. .Licking shales ... - 100-150 



4. Black Hand conglomerate and Granville beds - 85-90 



3. Raccoon shales ------ 300 



2. Sunbury black slate - - - 10-15 



1. Sunbury calciferous sandrock 2 - 90-100 



The following year Dr. Orton published a "Note on the 

 Lower Waverly Strata of Ohio" in which for the first time the 

 Waverly black shale of southern Ohio was correctly correlated 

 with the black shale directly above the Berea grit in northern Ohio 

 for which the name Berea shale was proposed. This furnished 

 the key for the correct correlation, between northern and south- 

 ern Ohio, of the lower formations of the Waverly series, which 

 was summarized in the following table :
