161 II. P. II. BRUMKLL — GAS AND PETROLEUM IN ONTARIO. 



Clinton. — The Clinton, on entering Canada through the Niagara penin- 

 sula, consists of a band of green shale 24 feet thick underlying IS feet of 

 limestone, though in the wells of the Provincial Natural Gas and Fuel 

 company in Bertie township the shales are apparently entirely wanting, 

 the formation consisting, it is said, of 30 feet of white crystalline dolomite, 

 which is grayish toward the base. In number 1 well of the Port Col- 

 borne company there were found beneath the dark shales, indicative of 

 the base of the Niagara. 72 feet of marls and dolomites, which are in all 

 probability attributable to the Clinton. The formation appears to thicken 

 toward the northwest, gradually diminishing again, as proved by the ex- 

 posure which trends to the north from Hamilton toward Collingwood, a 

 little south of which it takes a sweep to the westward. In Wentworth 

 county, in the township of Flamborough West, the Clinton is seen to rest 

 upon about 8 feet of whitish sandstone, constituting the " gray band," 

 which is apparently missing in Welland county, but on the northern 

 extension of the formation proves a very conspicuous feature, forming a 

 terrace upon which the' shale and limestone of the upper part of the 

 Clinton occur. In the many records of wells drilled in the interior of the 

 province evidence is wanting to estimate the thickness or character of 

 the Clinton, though in one, that of a boring at Waterloo, there were said 

 to have been found 114 feet of blue shale lying immediately above red 

 shale undoubtedly of Medina age. In all probability there have been 

 included in this 114 feet the dark shales of the Niagara. 



Medina. — Following immediately upon the Clinton and, where present, 

 the sandstone of the gray band is a great thickness of red and white 

 sandstones and red and green shales which constitute the Medina. This 

 formation has its greatest thickness in the Niagara peninsula, gradually 

 diminishing toward the north, where, at Cape Commodore, in Grey 

 county, there are seen beneath the Clinton limestone 109 feet of red and 

 green shales resting upon strata of the Hudson River formation. In 

 number 1 well, drilled in Port Colborne by the Port Colborne company, 

 the measures penetrated for a distance of 770 feet were — 



Red shale, with thin bands of white sandstone 50 feet. 



Red and white sandstone 53 " 



Soft red shale, with bands of gray and green G07 " 



Total 770 " 



Drilling ceased at this point at a distance of at least 200 feet above the 

 base of the formation, as in a well on lot 6, concession 15 of Bertie town- 

 ship, there were found 1,000 feet of strata attributable to the Medina. 

 The best record of the upper beds of the formation is that of the bottom
