THE ARTESIAN WATER SUPPLY OF EASTERN FLORIDA.

The first flow of water in and near Fernandina is reported to be encountered at a depth of from 4oo to 5oo 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 obtained 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 6oo feet. In the log of the new well at the city water works limestone or what was te ',ed by the driller, Mr. H. Walker, "water rock" was encountered at a de4th ..5f 56 feet. This was reported to consist of alternating hard and soft strata and the flow of water to increase witt 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 inches in diameter and was drilled to a total depth of 640 feet. It is reported cased 618 feet. At ,this depth an abundance ot 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 sufficient 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 increased the amount of flow to such an extent that the pumping ot the water became unnecessary. This well is reported to have had a pressure of 14 pounds when first drilled in I889. The following record of measurements of the flow of this well were kindly supplied by Mr. R. V. Nolan, Superintendent of the City Water works.

In 19o6 a second well was drilled for the city by Mr. H. Walker. This well contains 120 feet of IO inch casing; 356 feet of 8 inch casing; and 455 feet of six inch casing and is drilled to a total depth of 733 feet. The head of ,the water in this well as shown by the. pressure gauge J[anuary 28, 1910, was 14 pounds to
