THE ARTESIAN WATER SUPPLY OF EASTERN FLORIDA. 
131 
The first flow of water in and near Fernandina is reported to 
be encountered at a depth of from 400 to 500 feet after drilling 
through a considerable thickness of sand and blue to greenish 
clay or marl. The water at this depth as indicated by notes ob¬ 
tained from well drillers comes from a sand stratum confined 
there by the overlying very compact blue to greenish clays. 
The second water bearing stratum or chief source of supply is 
obtained at or about the depth of 600 feet. In the log of the 
new well at the city water works limestone or what was te rued 
by the driller, Mr. H. Walker, “water rock” was encountered at 
a depth of 556 feet. This was reported to consist of alternating 
hard and soft strata and the flow of water to increase with depth 
as each hard stratum was penetrated. 
The first well drilled on Amelia Island was put down for the 
City of Fernandina by Messrs Wade and Hampton in 1888. This 
well is located 5 blocks east of the city postoffice and is eight in¬ 
ches in diameter and was drilled to a total depth of 640 feet. 
It is reported cased 618 feet. At this depth an abundance of 
flowing water was obtained, but the well subsequently became 
filled with sand and the flow decreased to such an extent that in 
order to get a sufficent amount of water to supply the city pumping 
had to be resorted to. Later the well was drilled deeper to a 
depth of 731 feet. The flow, however, is reported not to be as 
great as it was originally although the deepening of the well in¬ 
creased the amount of flow to such an extent that the pumping of 
the water became unnecessary. This well is reported to have had 
a pressure of 14 pounds when first drilled in 1888. The fol¬ 
lowing record of measurements of the flow of this well were 
kindly supplied by Mr. R. V. Nolan, Superintendent of the City 
Water works.

In 1906 a second well was drilled for the city 1 w Vr. H. 
Walker. This well contains 120 feet of 10 inch casing; ' ■ Let 
of 8 inch casing; and 455 feet of six inch casing and :sYfilled 
to a total depth of 733 feet. The head of the water in tins
