Onondaga county. Natural gas is found at Baldwinsville, north 

 of Syracuse, where it has been in use since 1897. The pool supports 

 about fifteen active wells. The main supply comes from the Trenton 

 formation at depths below 2200 feet but some gas occurs in the 

 Medina and Oswego sandstones at higher levels. Some of the wells 

 were prolific at first, yielding as much as 3,000,000 cubic feet a day; 

 they have been persistent producers, although their flow is now 

 considerably reduced. The conditions of the occurrence were care- 

 fully worked out by Prof. Edward Orton. The following is the log 

 of the first well, put down on the Monroe farm just northeast of 

 the village.

A few wells have been drilled in the vicinity of Syracuse, but 

 without any marked success in the discovery of a gas supply. One 

 well, drilled by the Empire Portland Cement Co. on the site of its 

 former works at Warners, reached a depth of 3526 feet, encountering 

 the Trenton limestone at 2700 feet and cutting a sandstone which
