Flint shell (?) (cased to), at 361 feet.

Limestone, " 465 "

Bottom of (white) gas sand " 481 " 



Bottom of well, " 492 " 



Bock much like that at the top. 



The Blocker Wells, Williarmoille. (From Mr. John Blocher.) These 

 are located on Evans street, near the eastern end of the village. Two pro- 

 duce gas and the other water. In boring the last the drill passed through: 



Limestone, 6 to 8 feet. 



Gravel and limestone alternating in beds of '•>> or 4 ft. to 125 " 



Dry limestones and shales, to 500 " 



Water at 75 and 125 feet ; dry all the w ay below. 



This well was bored on the very edge of the limestone terrace, and the 

 beds of gravel referred to were evidently crowded into crevices in the rock. 

 Similar intrusion of gravel is seen in the quarry at the Front, in the city of 

 Buffalo. Water in this well tills a three-inch pipe two feet above the surface 

 of the ground, and half tills it at six feet. It is charged with sulphuretted 

 hydrogen and some mineral matter. 



The second well, lying about one hundred feet to the east of the one 

 described, struck a strong vein of sulphur gas at 500 feet. Mr. Blocher 

 thinks this flowed a quarter of a million feet a day on the start. 



Well No. 3 is situated about 200 feet north of the others. 



In this the distance to rock was 107 feet. 



Top of Niagara limestone, at 440 " 



Top of Clinton limestone, " 700 " 



Top of Medina sandstone, " 725 " 



Through gas sand, 851 " 



Total depth, 862 " 



Cased to 165 feet. Water sufficient to till an eight-inch pipe w as found 

 five feet above bed-rock. Twenty thousand feet of gas were found in the 

 Clinton, but none in the Medina. Wells Nos. 2 and 3 are now together 

 furnishing about 25,000 cubic feet of gas per day, most of which is used 

 under the boilers at the power-house of the Williams ville and Buffalo 

 Electric railway. (Record from driller, Mr. J. W. Stearns, Akron, X. V.)
