Report of the State Geologist. 



In the above record the rock called Lower Helderberg " is probably 

 the water-lime of the upper Salina. This well was located only six feet from 

 Well No. 1. 



Dr. Julius Pohlman, of Buffalo, examined the samples from Well No. 2. 

 His record, quoted from Mr. Ashburner's report, is as follows ; 



" Beginning at a spot where the rocks of the water-lime group, suitable 

 for the manufacture of cement, had been removed, and which is seventy feet 

 above the level of lake Erie, or 643 feet above tide- water, the drill encoun- 

 tered the following strata : 



From 1- 25 feet, Shale and cement rocks in thin streaks. 

 25- 30 " Tolerably pure cement rock. 

 30- 43 " Shale and cement rock in thin, streaks. 

 43- 47 " Pure white gypsum. 

 47- 49 " Shale. 

 49- 61 " White gypsum. 



61- 62 " Shale. 



62- 66 " White gypsum. 



66- 73 " Shale and gypsum, mottled. 



73-131 " Drab-colored shale with several layers of Avhite gyp- 

 sum, measuring eighteen feet in all. 

 131- 133 " Dark-colored limestone. 

 133- 137 " Shale and limestone. 

 137_ 140 » Dark-colored compact shale. 

 140- 720 " Gypsum and shale, mottled, and in streaks. 

 720- 725 " Limestone. 

 725- 760 " Soft red shale. 



760- 785 " White solid quartzose sandstone, very hard. 



785-1305 " Soft red shale. 

 " At 1,305 feet the drill was stopped. Permanent water was struck at 

 forty-three feet; gas of fair quality as well as quantity, at 452 feet; salt 

 water, leaving on evaporation about twelve per cent, of salt, was found at 555 

 feet. A shaft, twenty feet square, was sunk on the premises later, for the 

 purpose of determining the feasibility of mining the gypsum, but the rush of 

 water through the gypsum layer at forty-three to forty-seven feet, was so 

 strong that a pump with a capacity of 2,000 gallons per minute failed to 

 make any impression upon it. and the attempt was abandoned." 



Well No. 3, according to Mr. Ashburner, was 517 feet deep, striking 

 gas at about 460 feet. After torpedoing the well the gage showed sixty
