the most noticeable fossil. Although the stone, so far as explored, here 

 appears rather slaty, it would probably become thicker and very useful 

 for common building on reaching the undisturbed bedding. The situa- 

 tion of this outcrop demonstrates either a wide detour westward of 

 the boundary line separating the geographical areas of the Corniferous 

 and overlying shale, or an isolated area of Corniferous surrounded by 

 the shale, since it is sufficiently certain that the black slate underlies 

 the city of Bucyrus. On the other hand, the Bucyrus area of black slate 

 may be an outlier only, surrounded on all sides by the underlying lime- 

 stone. Besides the places above mentioned, there are many indications of 

 the occurrence of the Upper Corniferous in the bank of the Sandusky, on 

 the S. E. I section 24, in Dallas township, on the land of Mr. McNeal. 

 A little below Mr. McNeal's, in the same section, fiat stone, answering to 

 the Upper Corniferous, was taken out of the bed of the Sandusky in 

 email quantities, about twelve years since, on land now owned by Mr. 

 James Echart. 



The Lower Corniferous is also exposed in the Broken Sword Creek, 

 and at Benton, in the Sycamore Creek. At the latter place it is worked 

 a little by Mr. Benjamin Kuntzman and Mr. Martin Stoertzer. It may 

 be seen more or less in the bed of the creek between Benton and the 

 county line. Throughout this distance the exposures are so meager, 

 owing to the prevalence of the Drift, that the rock cannot be seen except 

 where the water actually runs, and no reliable section can be obtained. 

 It is a coarse-grained, dirty, fossiliferous, and magnesian limestone, with 

 considerable bituminous matter, in beds varying from six to twenty 

 inches in thickness, suitable for abutments and heavy walls. Near 

 Oceola the Lower Corniferous is considerably exposed, and is quarried for 

 general building stone and for quicklime. The following quarries are in 

 the Lower Corniferous at this place, viz., those of John Schnavely, David 

 Schnavely, widow Schnavely, Luther M. Myers, Dennis Coder, Gotleib 

 Doerer, and Joseph B. Christie. Of these, John Schnavely's and Mrs. 

 Schnavely's are in the upper portion of the Lower Corniferous, the princi- 

 pal fossils of which are brachiopods. The stone is light-colored and crys- 

 talline, appearing somewhat saccharoidal, in beds of about three inches. 

 The lime made is nearly white, but slightly creamy. The quarries of 

 Messrs. Myers, Coder, Doerer, and Christie are in lower beds. The stone 

 of these quarries, when fossiliferous, is characterized by a profusion of 

 corals, with very few brachiopods. It is bituminous and also magnesian, 

 harsh to the touch, appearing often much like a sandstone. It is a much 

 darker colored stone than that of Schnavely's quarry, but the lime made 

 from it is equally white. Large portions of the stone are perfectly free
