On the eastern side of the valley, along the line of the Buffalo, 

 Rochester and Pittsburgh Railway, are a considerable number of salt 

 wells, and the records of several of them will be of value for our 

 purpose. About ten rods from the station of the B., R. & P. R. R. is 

 one of the Gouinlock and Humphrey wells.

(i.) There is a slight difference in the record of the lower portion of this well as reported by 

 Professor Bishop and Dr. Gouinlock and that furnished by Mr. Percy. Bishop and Gouinlock report 

 that salt was reached at a depth of 1803' and that the well was drilled 76' deeper, making its total depth 

 1879'. Mr. Percy's notes give the depth at which salt was reached as 1807' and then state that it was 

 drilled 84' deeper, making it 12' deeper than the other record, or with a total depth of 1891'.
