FLORIDA STATE GEOLOGICAL SURVEY. 
The 498-foot well is owned by George A. Chalker and was drilled 
in 1907 by D. 'C. Stafford. The well is six inches in diameter 
at the top and one and a quarter inches at the bottom. The pres¬ 
sure of this well as indicated by the pressure gauge, January 10, 
1910, was 18.5 pounds, or a pressure sufficient to cause the water 
to rise 42.7 feet above the surface. The elevation of the well is 
approximately 24 feet above the level of the water in Black 
Creek; thus, with the head of 42.7 feet above the surface, would 
give the well a total head of 67.7 feet above the water in Black 
Creek. The temperature, of the water at the point of overflow 
was reported as 72° F. The first rock of which note was made 
was at a depth of 68 feet. 
The well of C. C. Howard, two miles northeast of Middle- 
burg, has a depth of 490 feet. The well was bored by D. C. 
Stafford in 1907, is cased 80 feet, and is four inches in diameter. 
The pressure of this well could not be taken, but it is reported 
to have a head of 21 feet above the surface. 
Another well, two and a half miles northwest of Middleburg, 
was sunk by D. C. Stafford for Messrs. Long & Buddington, in 
1907. The exact depth of this well could not be obtained, but 
it was reported to have a depth of about 370 feet. The well 
flows and gives an abundant supply of water, but measurement 
of the head could not be made. 
In addition to the above wells is one eight and one-half miles 
northwest of Middleburg, or six miles southeast of Maxville, on 
the west bank of Yellow 'Water Creek, a tributary of the north 
fork of Black Creek. This well is located in the northwest part 
of the northwest quarter of the southwest quarter of Section 17, 
Township 4, Range 24 east. It is owned by Messrs. Long & 
Buddington, and is said to be 370 feet deep. It is a three-inch 
well and was drilled in 1907 by D. C. Stafford. The head of 
this well is reported to be 30 feet above the surface and the first 
flow encountered was at a depth of 44 feet in a stratum of black 
pebbles.
