62 ECONOMICAL GEOLOGY. 



into the St. Peters and Potsdam sandstones, but none of them 

 hitherto reported, except the well at Beardstown, have pro- 

 duced either gas or oil in paying quantities. 



The boring at Rivertou, seven miles east of Springfield, was 

 carried to the depth of 2,004 feet below the horizon of coal No. 

 5, and about 1,380 feet below the base of the coal measures. 

 From the detailed record furnished by Mr. Swan, under whose 

 direction the work was done, it is impossible to define the exact 

 horizon where the bore terminated, but it undoubtedly passed 

 entirely through both the productive gas horizons of Ohio mid 

 Pennsylvania. Neither oil, gas or artesian water was found in 

 this well. 



The artesian well at Carthage, in Hancock county, encoun- 

 tered the St. Peters sandstone at the depth of 975 feet, where 

 a fine flow of mineral water was obtained, but no indication of 

 the existence of any productive deposit of oil or gas was ob- 

 served. 



The artesian well at Monmouth reached the St. Peters sand- 

 stone at the deptji of 1,088 feet, but no flow of water was ob- 

 tained, and no indication was found of the presence of gas or 

 oil. At Canton in Fulton county a well was bored through 

 both the gas producing horizons without obtaining either gas 

 or artesian water, and in northern Illinois many successful 

 artesian wells have been sunk, all passing through the Trenton 

 limestone, the lowest formation from which gas has as yet been 

 obtained, without in a single instance obtaining gas sufficient 

 to justify its utilization. 



At Canton, a boring was made to the depth of 2,333 feet by 

 Messrs. Atwater & Co. in search of artesian water, which proved 

 a failure. The St. Peters sandstone was reached at the depth 

 of 1,415 feet, but no flow of either water or gas was obtained 



from it.
