in the left bank of the Scioto. It is in the Delhi beds, exposed twelve or 

 fourteen feet. Stone is hauled from here to Delaware and burned "for 

 lime by Mr. G. W. Corbin. 



The water in Mill Creek, at Bellepoint, is on No. 3 of the foregoing 

 section, taken near the county line, and has excavated a channel in it 

 to the depth of fifteen feet, with a heavy-bedded, firm .stone of the same 

 kind in the bed of the creek. Above these heavy layers is a thickness 

 of twelve feet of cherty beds, varying from four to nine inches, but usually 

 from four to six. John Jones's lime-kiln is excavated in these beds. 

 John Courtw right, four and a half miles below Bellepoint, has a quarry 

 in the same horizon. Daniel Kelly's quarry is on the east side of the 

 Scioto, a mile and three-quarters below Bellepoint. A quarter of a mile 

 below Millville, on the east side of the river, are the quarry and kilns of 

 Mrs. Margaret Evans. The hard, bluish layers of No. 3 of the section at 

 Colvin's lime-kilns are here wrought for lime-burning, though the bed- 

 ding here is less heavy than at Colvin's, being generally about three 

 inches. In the river bank, some distance below the quarry, .but just west 

 of it, the Waterlime is exposed, and was formally burned for lime. It is 

 distinguished as "the white stone," from the whiteness of the quicklime 

 made from it, that from the Lower Corniferous being a little dark or 

 ashen. East from Evans's kiln, a third of a mile from the river, are 

 several sink-holes seen on the land of W. S. Sipes. On examining these, 

 the Delhi beds are found .to be about fifteen feet below the surface. 

 What portion of that interval is taken up with those bed^, or what is 

 occupied with Drift, it is impossible to say; but the blue beds of the 

 Delaware stone should bo in situ very near that horizon. These sinks 

 are on the plains, about eighty feet above the river. The whole tract of 

 land between the Scioto and the Olentangy, in Delaware county, is liable 

 to the.=e sink-holes. Very many were met in the survey that are not 

 mentioned in this report. 



The so-called "fire-stone" of William Warren's quarry, half a mile west 

 of Millville, is the same as that burned for quicklime by Mrs. Evans, 

 but is overlain at Warren's quarry by two feet of Delhi beds. It is ex- 

 posed also half a mile further north, on land of C. P. Burner and Thomas 

 Jones. 



The stone placed in the piers of the highway bridge over the Scioto, 

 at the mouth of Bogg's Creek, was taken from the quarry of Rpv. C. H. 

 Perkins. It is in heavy beds, soft and vesicular, becoming' firm after 

 exposure to the air, and belongs to the lowest member of the Lower Cor- 

 niferous, No. 3 of the section near the south county line. The quarry 

 is located on a run tributary to Prairie Run, on the east side of the Sci-
