5. Black Hand formation (conglomerate) is the name given by 

 Professor Hicks in 1878 to the deposits of coarse sandstone and 

 conglomerate exposed at Black Hand in the gorge of the Licking 

 River and about Hanover. 1 Both of these localities are in Hanover 

 township, in the eastern part of Licking county. We find, as in 

 the case of most conglomerates, that when this formation is 

 followed for some distance there are quite decided differences 

 in the lithologic character of the rocks. In the vicinity of 

 Newark and Granville they are mainly sandstones, with some 

 layers of shales and two comparatively thin strata of conglom- 

 erates. Professor Hicks states that these beds are well exposed 

 at Granville and are only a local modification of the Black 

 Hand conglomerate, and for convenience he designated them 

 "the Granville beds." 2 Professor Andrews in 1870 called this 

 division the Waverly conglomerate; 3 but this name was preoc- 

 cupied, because Waverly had already been used for the name of 

 the series. He correlated the conglomerate at Black Hand 

 with that of the Waverly and gave its thickness at that locality 

 as probably 50 or 60 feet. 4 



At Havens' quarries, on the farm of Mr. G. W. Havens, one 

 and one half miles southeast of the central part of Newark, is a 

 good exposure of the sandstone phase of this formation. The 

 section begins in the conglomerate stratum on the bank of 

 Quarry Creek below the quarries, where an excavation has been 

 made in prospecting for gold, and continues to the top of the 

 bank above the quarry on the eastern side of the run. The 

 quarry on the western side of the creek is shown in Fig. I, the 

 lower part of which is in the Black Hand and the upper the 

 Logan formation.
