ten inches, and is very valuable for all uses. It is a part of the Water- 
lime. Stone of the same kind is found in Bogg’s Creek, two miles from 
the Scioto, on land of John Irwin. In Thompson township the Water- 
lime is seen on the farms of Simon Charles and Jonathan Fryman, a 
mile and a quarter west of the Scioto, at the road-crossing of Fulton 
Creek. It is in thin, blue beds, the same as at Cone’s mill, and has been 
used somewhat in cheap foundations. Bogg’s Creek, where it enters the 
Scioto, is on the Waterlime.
