THE ARTESIAN WATER SUPPLY OF EASTERN FLORIDA.

depot at Lake Helen, as recorded by the Florida East Coast Railway, is 70 feet.* The wells recorded from this place range in depth from 130 to 238 feet. The Bond Sand-Lime Brick Company own several three-inch wells ranging in depth from 130 to 140 feet. The water is reported to rise within 28 feet of the surface. A well for Mr. G. W.

The principal water supply is obtained from a depth of 2Jo feet. The water is hard and is only slightly charged with hydrogen sulphide.
NEW SMYRNA.
The artesian conditions at New Smyrna are essentially the sa. ne as those given for Daytona. The wells in this vicinity range i,depth from io8 to 144 feet. The water is hard and is charged with hydrogen sulphide and is used to a large extent for irrigating puposes.
The following is an analysis of the water from the well of Mr. W. L. Widmeyer, made. in the office of the State Chemist, B. H. Bridges, analyst.

OAK HILL.
Oak Hill is eleven miles south of New Smyrna on the Florida East Coast Railway and about four miles north of the head of Ind(lian River. Several flowing wells occur in the vicinity of this place. These wells are reported to be about 130 feet deep. The water is hard and sulphuretted. Approaching the head of Indian River. some four or five miles south of Oak Hill, flowing wells of brackish water are obtained. Mr. T. J.
