same field. These small sandstone deposits are quite common in that 

 neighborhood, and, ia fact, the whole appearance of the rocks is so sandy 

 that Mr. George G. Shumard reported the following section in the pros- 

 pectus of the " Logan and Champaign Petroleum Company," in 1865 : 



FEET. 



1. Drift, gravel, and bowldera of sienite, gneiss, red feldspar, homWende 



and mica schist, quartz, sriuddtone, etc 20 



2. Black and dark-brown bitnminouM slate 40

6. Black and dark-browa bituminous slate, contaiuing large septarian seg- 



regations and nodulos ot iron pyrites l.'JO 



7. Hard, light-gray, ealcarea-silicious sandstone, thickness as far as exposed- 20

 Mr. J. M. Inskeep, who worked the drill for the said company, reports 

 the section obtained on B. Ewing's land, in southern part of Monroe 

 township, as follows : 



FEET. 



Slate 6 



Flint 5 



Sandstone 639 



Eed slate 12 



Blue limestone 43

At that point patience, hop>e, and funds failed, and the project was 

 abandoned. It is much to be regretted that a more careful or more skill- 

 ful record was not kept of this boring. The "flint 5 feet" evidently was 

 the upper course of the Corniferous, but it is difficult to understand what 

 could be included in "639 feet of sandstone." Mr. Shumard's second, 

 third, and fourth divisions evidently refer to the Huron shale, and his 

 fifth to the upper courses of the Corniferous, but his sixth and seventh 

 would seem to be purely imaginary or very much confused. 



There are traditions of a former sandstone quarry on the hill top east 

 of Zanesfield, from which the neighborhood was supplied with grind- 

 stones, and some still hope that it will be rediscovered. But Dr. B. S. 

 Brown, of Bellefontaine, whose retentive memory carries the treasures 

 of nearly three-quarters of a century of close observation, dissipates this 

 hope and vindicates geology by remembering how the ancient mason 

 hewed his grindstones from an immense (Waverly) sandstone bowlder, 

 and split his millstones from granitic ones. There is now another large 

 mass of Waverly sandstone lying on the side of a slate valley on Mack- 

 achack, half buried in gravel and the debris of slate, and it has been
