BROADHEAF — WELL AT ST. LOUIS INSANE ASYLUM. 221 

 ABSTRACT OF THE RECORDS. 



The borings indicate 63 ft. of Clay, 

 6 " Coa'l, 

 360 " Shale, 

 2721; " Limestone, 

 435 " Sandstone. 



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

 below the surface ; at 134 ft. an 8 or 10 inch opening was struck, 

 and the water sank in the well to a depth of 1 28 ft. Salt water 

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

 a strong petroleum smell was recognized. Sulphur water was 

 reached at 2140 ft. At 2256 the water in the sand-pump indi- 

 cated three per cent, of Salt ; at 2957, four and a half per cent ; 

 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 : 



At the depth of 3127 ft. the thermometer indicated 106°.

It is to be regretted that no tests of temperature were made 

 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. 



TUBING. 



A cast iron tube of 1 1 ? 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
