A PRELIMINARY REPORT ON CLAYS OF FLORIDA 235

 Sedimentary kaolin also occurs two miles south of Fairbanks, on Hatchett Creek. The overburden here is less than two feet. The thickness and extent of the deposit and its relation to a nearby gray clay was not determined.
 Citrus, Clay and DeSoto Counties-Sedimentary kaolin has been reported to occur four miles east of Inverness, and seven miles west of Floral City, in Citrus County, in the region about Brooklyn and Lake Geneva, in Clay County, and in the vicinity of Arcadia, in De Soto County. These occurrences, however, were not verified.
 Hernando County-Sedimentary kaolin was noted eight miles south of Brooksville on the Brooksville-Dade City road. The deposit here is approximately twenty feet thick and is underlain by abluish-gray jointed clay. The overburden is less than three feet.
 This formation is also exposed in an abandoned phosphate mine, ten miles east of Brooksville and three miles west of Rital. Here there is three feet of sand as overburden and twenty feet of the clay-bearing sand exposed. Water in the bottom of the pit concealed the lower part of the formation, so its exact thickness is unknown. The relation of the sedimentary kaolin to the hard-rock phosphate was not worked out in detail.
 Highlands County-Sellards and Gunter' report "kaolin" in this county, but do not give specific locations. Sedimentary kaolin is no doubt the material referred to. As stratigraphic and physiographic conditions are essentially identical with those in Polk, Lake, and Putnam counties, it is not at all.improbable that occurrences of this material should be found in Highlands County.
 Lake County-Lake County is one of the principal producers of sedimentary kaolin in Florida. Numerous deposits are known in the south-central part of the county, south of Lake Harris, and along the Palatlakaha River for a distance of ten or twelve miles.
 Two plants are actively engaged in mining this material about two miles east of Okahumpka, near the junction of the Palatlakaha River and Lake Harris. One of these is the Florida China Clay Corporation and the other is the Lake County Clay Company. The plants are about one mile apart and both are located on spurs of the Atlantic Coast Line.
