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 Courtwright, 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 beds, or what is 
occupied with Drift, it is impossible to say; but the blue beds of the 
Delaware stone should be tn setu 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 these 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 quickliime by Mrs. vans, 
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. F. 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 Rev. 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-
