basis of increase from 4,500 feet to 5,000 feet in the Bedell well, a 

 temperature of about 144° Fahrenheit should be found in the Geary well 

 at 6,052 feet, its present depth, and this estimate is probably very nearly 

 correct, since Mr. Pew reports that a temperature of 140° Fahrenheit 

 was recorded at 5,800 feet in the Geary well, which is about what the 

 West Elizabeth and Wheeling results would indicate for that depth. 



Record of the Well 



The following is the record of the R. A. Geary well, or No. 1770 of 

 the People's Natural Gas Company, to its present depth. It is located 

 5 miles northwest from McDonald, Pennsylvania, at the head of Little 

 Raccoon Creek, near the line between Washington and Allegheny coun- 

 ties. The well mouth is about 1,050 feet above tide and begins 130 feet 

 below the horizon of the Pittsburgh coal bed.
