The location of this find is in Section 27, of Columbia 

 Township, just north of Observatory Avenue, and west of 

 Shaw Avenue, thus being but a few yards outside of the 

 limits of the City of Cincinnati, and on the brow of a small

 as compared with its original extent. The swampy ground 

 is ten feet lower than the surface level of the .shafts. The 

 springs abounding in this mire are the principal .sources from 

 which Crawfish Creek arises. This creek, which is a direct 

 tributary to the Ohio, flows first to the southeast and then to
