In the deep well the sandstone, four hundred and forty-one feet thick, 

 struck at a depth of six hundred and thirty-eight feet, is, I have no 

 doubt, the Waverly. The 'thirty-five feet of slate at the bottom of the 

 well may be the top of the Ohio black slate (Huron shale), or, possibly, 

 it is a slate interstratified with the Waverly near the bottom. A slate 

 sixteen feet thick is found in the lower Waverly on the Ohio Eiver, in 

 Scioto and Adams counties. 



Iron Ore. — Iron ore of excellent quality is often found in this and adja- 

 cent townships. It is always in nodular form, and is derived from the 

 disintegrated clay shales in the hill sides, from which it is washed out. 

 Sometimes very large nodules are found. It is often difficult to trace the 

 ore to its original bed, but where I have succeeded in doing this the 

 nodules are too few to warrant drifting into the shales for them. Doubt- 

 less other and better localities will be found where drifting may be 

 profitably done. The following is an analysis, by Prof. Wormley, of a 

 sample of the ore from the farm of James Dutton, in this township :
