THE ARTESIAN WATER SUPPLY OF EASTERN FLORIDA. this well is hard and is charged with hydrogen sulphide. In addition to the above well Mr. McLain has two wells on Mullet Lake, on the St. Johns River about four miles slightly west of north from Geneva. Both of the wells furnish salt water impregnated with hydrogen sulphide and are not used. One is seventy-five feet deep and is said to flow two feet above the surface, the other' is 135 feet deep and the water is reported to rise to within one foot of the surface. The apparent difference in head is due to the difference in the elevation of the two wells. Mr. W. B. Raulerson owns a two-inch well five miles northwest of Geneva and near the St. Johns River. This well is 76 feet deep and is cased 72 feet and furnishes a small flow of salt-water which rises a few inches above the surface. The first flow in the well was encountered at a depth of 70 feet. An increased flow was obtained at seventy-two and one-half feet. The first water was reported to be more salty than the second, as was indicated when the first flow was cased off. Owing to inability to drill deeper with the light drilling outfit used, the boring was discontinued. Mr. Raulerson states that the water is more salty in seasons of drought than in seasons of normal or heavy rainfall. A two-inch well owned by Chase & Company, two miles southeast of Geneva on Lake Harney is 35 feet deep. This well was sunk by F. B. Bradley and is cased 34 feet. It has a head of four feet above the surface. The water is fresh and is only slightly charged with hydrogen sulphide. ORLANDO. Orlando, the county seat of Orange County, lies in the lake region of Florida. The elevation at the depot as given by the Atlantic Coast Line Railroad is i I I feet. Several wells have been drilled at Orlando. These are non-flowing wells, the elevation being too great to obtain a flow. The deep wells at this locality are used principally for drainage and for the disposal of sewage, the city water supply being obtained from one of the small lakes. A few private wells in and around Orlando are used as a source of water supply. A well near the north edge of the city owned by Mr. F. A. Lewter, has a total depth of 216 feet and is cased 86 feet. The water is used for general purposes. A second well at the ice plant is used in cooling pipes in the manufacture of ice. This well is 470 feet deep. The use of bored wells for the disposal of sewage has been discussed in the preceding paper on water supply. The practice is regarded as unsanitary, 169
