240 FLORIDA GEOLOGICAL SURVEY-I5TH ANNUAL REPORT

 A six-foot stratum of the sedimentary kaolin-bearing sand, overlain by three feet of soil, is exposed in a well at the home of B. S. Quarterman, Sec. 34, T. 13 -S., R. 20 W. The clay formation is underlain by fuller's earth, which is reported to be twenty-three feet in thickness.
 Pasco County-Exposures of the sedimentary kaolin sand were noted around the south border of Mirror Lake, a few miles northwest of Dade City. The thickness and extent of this deposit was not determined.
 The plastic kaolin also appears on the property of Jas. Lampson, one-half mile east of the Atlantic Coast Line Railroad and three miles southeast of Dade City. This deposit is overlain by about three feet of soil. The extent of this deposit is reported to be more than ten acres.
 Another occurrence of this clay is on the property of J. H. Klocker, one mile northwest of San Antonio, in Sec. 34, T. 24 S., R. 20 E. A boring indicated three feet of surface sand, six feet of redclay sand, and three feet plus of the white clay-bearing sand. The full thickness and extent of this deposit was not determined.
 Polk County-The sedimentary kaolin occurs in numerous places in Polk County in the vicinity of Bartow Junction (Lake Alfred) and Winter Haven.
 Putnam County-This county is one of the principal producers of sedimentary kaolin in Florida, as shown on preceding pages. Numerous occurrences are known in the region about Edgar, Johnson and McMeekin.
 The Edgar Plastic Kaolin Company operates one mine at Edgar. A generalized section at this locality is:
 Overburden ............................................. 6 to 20 feet
 Clay-bearing sand ...................................... 15 to 30 feet

 The clay is underlain in places by a red-streaked clay, two feet in thickness, in places by a limestone and in other places by a green clay. Fuller's earth is reported to underlie the green clay in places.
 The Foster Kaolin Company's mine, now abandoned, is located at Johnson. Here the overburden ranges from twelve to twenty feet, and the clay formation is approximately thirty feet in thickness.
 Sedimentary kaolin has also been found on the Monroe property in Sec. 32, T. 10 S., R. 23 E. This is only a short distance southeast of McMeekin and southwest of Johnson.
