ABSTRACT OF THE RECORDS. 



The borings indicate 63 ft. of Clay, 

 6 " Coal, 

 360 " Shale, 

 2725 kt Limestone. 

 435 ki Sandstone. 



When the borings began, the water in the well stood at 40 ft 

 below the surface ; at 134 ft. an S or 10 inch opening was struck, 

 and the water sank in the well to a depth of 128 ft. Salt water 

 was obtained at 1220 ft. At 1225 and 1262 ft. from the surface

 at 3293, two per cent. ; at 3367, less than two per cent. ; at 3384 

 ft. three per cent. ; and below 3545, seven to eight per cent. 



TEMPERATURE. 



Experiments with a Fahrenheit registering thermometer indi- 

 cated the following ; 



It is to be regretted that r 

 above these indicated depths. 



In boring to the depth of 833 ft. the drill was often observed to 

 be highly magnetized, but after passing that depth no further in- 

 fluence was observed. 



A cast iron tube of 11} inches was first put down, reaching 

 from the top to the limestone in the bottom of the well. The 

 tube was then lined with wooden tubing, reducing the diameter
