St. Augustine. Of this large number it is possible to mention 
only a few. 
The first considerable flow in and near St. Augustine is ob¬ 
tained at a depth of from 170 to 180 feet after drilling through 
a five- or ten-foot stratum of dense hard rock. The material 
penetrated before reaching this hard rock stratum consists largely 
of sand near the surface, followed by 'blue clays with some shell 
and occasional thin layers of rock. A shell stratum often de¬ 
scribed as “coquina” occurs at a depth of about 60 feet. 
The material below the depth of about 180 feet consists of 
alternating hard and soft strata, largely limestones, with probably 
occasional flints. The flow of water increases as the limestone is 
penetrated. The chief large increase of flow occurs at a depth 
of about 520 feet and most of the wells at St. Augustine terminate 
at this depth. 
Water for the city of St. Augustine is obtained from two ar¬ 
tesian wells located about one mile north of the city. Well No. 1 
was drilled in 1897 by Mr. Hugh Partridge and had originally 
a depth of 371 feet. About 1903 this well was deepened to a 
total 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 gallons per day (1,664 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. Plorace 
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 188-1. They are now in use as private wells.
