road cut north of Tippecanoe. On the Stillwater, near Milton, the same 

 shale is seen at the base of the cliff, and on the east of the river on the 

 hill-side opposite. From the horizon of these localities, all below belongs 

 to the Cincinnati group. All the streams below this horizon, cut 

 through the upper strata of this group. The outcrop of the blue lime- 

 stone must be looked for up all the streams, far enough above these 

 localities to allow the rise to reach the horizon of the base of the cliffs.
