 ison Township. At the crossroads, two miles from the place where 

 the creek empties into the Muskingum River and a short distance 

 from the mouth of North Branch, the dark, ferruginous limestone 

 is exposed in the bed of the creek where good collecting material 

 is furnished. The section near the cross-roads follows: 1
