WELL RECORDS. 
The first deep well drilled in this field was the Guffey No. 1, located 
on the Stephen Jackson league, about 2,000 feet north of the hotel 
and lake. This well was drilled to a depth of 1,100 feet, and yields 
the following section:

The log is not complete, the well having reached a depth of 1,400 
feet. 
This well encountered considerable quantities of oil at various 
horizons, notably at 1,100, 1,250, and 1,400 feet, where drilling was 
stopped. Small quantities of salt water were also encountered at 
various levels, and at 822 feet gas was met with in such quantities 
as to blow out the drill and a large quantity of sand, mud, rock, and 
water, which seriously delayed the drilling operations. This well 
lias a strong flow of oil from the fine sand at a depth of 1,400 feet. 
Twenty-five hundred feet southeast of this well, and close to the 
location of one of the old Savage wells, the Atlantic and Pacific Oil 
Company has drilled two wells about 700 feet in deptli which have 
developed a strong flow of oil. Several oil-bearing horizons were 
found in the drilling, some of which are doubtless of commercial 
importance. 
The following logs of the Atlantic and Pacific well No. 2 and of the 
Sour Lake Springs Company well No. 1 were supplied by the driller, 
Mr. N. Sinclair. These logs are interesting and valuable from the
