tal depth of 550 feet. The well is 12 inches in diameter for 354 
feet; 9 inches for 17 feet; and four inches for 179 feet. It is 
reported cased to a depth of 100 feet. The head of the water is 
given as 33 feet above the surface or about 38 feet above sea level. 
The flow of the well when first drilled in 1897 was 2,396,000 gal¬ 
lons per day, (1664 gallons per minute). 
Well No. 2 is a 10 inch well and has a total depth of 500 feet. 
It is cased about 140 feet. The head of the water is the same as 
well No. 1 or about 38 feet above sea. ^ The total flow of this well 
is not recorded. This well was drilled in 1903 by Mr. Horace 
Walker. 
The water system at St. Augustine is now owned by the city. 
Formerly the city was supplied by five artesian wells, the system 
then being under private ownership. These wells were located in 
various parts of the city. They vary in depth from 250 to 500 
feet and range from 6 to^ 8 inches in diameter. The first of these 
wells was drilled in 1884. They are now in use as private wells. 
Several wells have been drilled at St. Augustine to supply water 
to the Ponce de Leon and other hotels of the Florida East Coast 
Hotel Company. One of these commonly known as the Ponce de 
Leon well reached a total depth of 1440 feet and is the deepest 
well in St. Johns County. The following log of this well has been 
made up from records kindly supplied by Messrs. MacGuire and 
McDonald under whose direction the well was drilled, supplemented 
by a partial set of samples from the boring. The original intention 
was to go to a depth of about 3000 feet in the expectation of ob¬ 
taining warm water. The well was begun November 27, 1886, 
and drilling continued until Februar}^ 24 of the following year. 
Owing to delay caused by the loss of the drill, boring was finally 
discontinued at the depth of about 1440 feet.
