of number 1 well, drilled by the Provincial company, on lot 35, conces- 

 sion 3, Bertie township, and which is as follows: 



Red sandstone , 55 feet. 



Red shale 10 " 



Blue shale 5 "

Bine shale 20 " 



White sandstone (" gas-n >ck ") 1(3 " 



Total , Ill " 



Throughout the gas-fields of Bertie and Humberstone townships this 

 section of the upper bods of the formation appears to lie unite constant, 

 only very slight variations being noted. The most marked is that in 

 number 9 well, drilled by the same company, and wherein was found — 



Red sandstone 55 feet. 



Red shale 10 " 



Blue shale 5 " 



White sandstone .• 20 " 



Illue shale 12 " 



Total 102 " 



The second white sandstone bed beneath was penetrated only four feet. 



in a well sunk on lot 11, concession 7, Barton township, Wentworth 

 county, and about forty miles to the northwest of the above-mentioned, 

 there were found 595 feet of red shale, with bluish bands, lying imme- 

 diately above the bluish shales of the Hudson River. Again, a few 

 miles northwest of this place, and at the insane asylum in Hamilton, 

 there were said to have been found 634 feet of red shale, and at Dundas, 

 three miles north of this, in a well sunk in the valley and begun in the 

 Medina, there were found 400 feet of red shale, in both instances resting 

 upon the Hudson River shales. To go back to the eastward again, there 

 were found in a well at Saint Catharines .548 feet of red shale. This does 

 not, however, show the entire thickness of the measures, which in a well 

 at Thorold, eight miles southward, proved to be 930 feet thick, as follows : 



Red sandstone 30 feet. 



Shale 57 " 



Gray sandstone 30 



Red shale 813 "
