Norwich Well and Section— The next well-record to be considered is 

 that of one drilled near Norwich, Chenango county, about thirty-five 

 miles northnortheast of Binghamton. The well was drilled by Mr A. W. 

 McQueen in 1887-'88, who kindly favored me with its record and a set 

 of samples. Natural gas was found at various horizons down to 1,200 

 feet, but in such small quantities that it would burn but a few hours 

 before being exhausted.
