236 H. T. II. BRUMELL — GAS AND PETROLEUM IN ONTARIO.

The Corniferous petroliferous over awide Area. — While the Corniferous af- 

 fords commercial quantities of oil only in Lambton county, explorations 

 have proved it to he petroliferous over a wide extent of country, including 

 the northern part of Kent, the eastern part of Middlesex, and southern 

 part of Oxford. In the county of Essex oil has been found at two points, 

 presumably in the Niagara or upper strata of the Clinton. At Comber, 

 in this county, small quantities of heavy black oil were found in a hard 

 limestone at 1,270 feet, and again at Walker's well number 2, on lot 8, 

 concession 6, Colchester township, oil similar in appearance and gravity 

 was found at 1,000 feet in a brownish limestone. This well is said to 

 have pumped five barrels per day. 



THE MEDINA AS AN OIL-PRODUCER. 



The only other formation wherein oil has been struck is the Medina, 

 in which, in Humberstone township, Welland county, it has been noted 

 in two wells. These are on lots 11 and 12, concession 3, and are said to 

 have flowed four and two barrels each per day respectively. The oil 

 occurs in the second white sandstone bed, about 100 feet beneath the 

 summit of the formation. The oil is of light claret color, of about 45° 

 Baume gravity, and is apparently free from sulphur. Further work in 

 search of this oil has not yet been undertaken. 



GAS-BEARING HORIZONS: CLINTON, MEDINA AND OTHERS. 



Localities indicated. — Gas is found in large quantities at two horizons 

 only, viz, one, which is still doubtful though in the neighborhood of 

 the Clinton, in Essex county; and in the Medina, in Welland. In the 

 former county, in the vicinity of Ruthven, Gosfield township, there have 

 been sunk several wells, in three of which were found huge quantities of 

 gas, in each ease emanating from a gray vesicular dolomite at a depth 

 of about 1,000 feet. 



Depth at which Gas is found. — In Welland count}', wherein the gas field 

 covers a much greater area than that of Essex, the gas is found almost 

 entirely in the Medina sandstone, about 100 feet below the summit of 

 the formation and at a depth of about 830 feet. The record of number 1
