Feb., 1916] Outliers of the Maxville Limestone 153 



Probably one of the most instructive outliers found occurs 

 4 miles north of Warsaw and 1 mile south-west of Blissfield 

 on the Blissfield-Warsaw highway. The exposure occurs in 

 the highway at the crest of the ridge and shows 9 feet of the 

 limestone in many layers resting conformably upon the Logan 

 shale a long section of which is exposed. Resting directly 

 upon the limestone is a bed of sandstone 12 to 18 inches thick, 

 sharply undulating, and strikingly unconformable. The sand- 

 stone is white to gray in color, very compact, and exceedingly 

 hard. The limestone is well weathered, is soft, buff to yellow 

 in color, and contains many fossils of brachipods and fenestellid 

 bryozoans. When completely weathered, as seen in the road- 

 way nearby, it becomes an ocherous earth. 



One of the most interesting facts is the presence of hard 

 concretionary nodules more or less silicified and definitely 

 embedded in the limestone. They are precisely like the 

 thousands of loose cobble stones seen in dozens of places where no 

 bed of limestone was found. The writer had believed for some 

 time that where beds of these loose cobbles were found, or where 

 they were numerous, they marked the place of the Maxville 

 limestone, but up to the finding of this outcrop he had no 

 positive evidence of their origin. 



It may be pointed out that this outcrop marks the crest of a 

 Mississippian hill, as these patches UvSually do. North, east, and 

 south the Mississippian surface falls a hundred feet or more. 

 In a hill close by, the Lower Mercer limestone is found only 

 50 feet above the Maxville — an interval that is usuallv 120 to 

 150 feet between the Lower Mercer limestone and the base 

 of the Pennsylvanian. 



Noting the elevation at which the various outcrops occur, 

 it is found they all lie in one plane very gently dipping to the 

 south-east. It may be stated further that the many beds of 

 cobble stones found at the Mississippian-Pennsylvanian con- 

 tact all lie in this same plane. This indicates in no uncertain 

 way that the cobble beds are the remains of the Maxville and 

 mark its place. 



The most westerly point at which a bed of cobbles was 

 found is in Licking County, 8 miles north-east of Newark and 

 4 miles north-west of Hanover. The exposure is in the roadway 

 on the western edge of Perry Township. The stones range 

 in size from the fist up to 15 or 18 inches in diameter, are
