at said Station would be about 415 feet above low water mark, and it 

 will be evident to any one on examination that the Cincinnati formation 

 extends to a line of springs 25 to 35 feet higher up the hill. At 

 least the Blue Limestone formation can be seen 15 feet higher than 

 the railroad track, where a wagon road has been cut on the hillside, 

 and the evidences would show its elevation to be about 450 feet 

 instead of 415 feet as given by Prof. Orton. Should this prove to be 

 the case, as it undoubtedly will, the Blue Limestone formation at 

 Station K will be in harmony with the altitude of the same formation 

 at other points given on page 414 of Volume First of the Survey.
