238 FLORIDA GEOLOGICAL SURVEY-I5TH ANNUAL REPORT

four-foot exposure of the clay-bearing sand may be seen above the level of the lake. The overburden is three feet of soil and the clay is thirty feet in thickness. This deposit is three miles east of the Lake County Clay Company's plant and one-half mile east of Yalaha.
 Levy County-An occurrence of sedimentary kaolin was noted in a road-clay pit in the northwest part of Bronson, about two hundred yards north of the Seaboard Air Line Railway station. About six feet of the clay-bearing formation was exposed, but the depth and extent of the deposit was not determined. The overburden was about three feet.
 Marion County-Occurrences of sedimentary kaolin have been found in both the extreme southeast corner of the county and in an area in the northwestern quarter of the county.
 A water well, dug on the property of Captain E. E. Greer, Sec. 32, T. 17 S., R. 26 E., in the southeastern part of the county, went through twelve feet of soil and surface sand, then through thirteen feet of sedimentary kaolin. The well stopped in the clay-bearing sand, hence its thickness is not known.
 Another deposit, also in Sec. 32, T. 17 S., R. 26 E., was found on the property of Harry L. Collins, about three-quarters of a mile northwest of the Greer occurrences. The overburden here consisted of five feet of loose surface sand and seven feet of red sandy clay (sandclay road material). Ten feet of the clay-bearing sand was exposed immediately below the red sandy clay. Its exact thickness and extent was not determined.
 In the extreme southeast corner of the county and extending into Lake County, near Altoona, is another deposit in which fifteen feet of the clay-bearing sand is exposed. It is overlain by five feet of sand. The thickness and extent of the clay formation was not determined. This deposit has been worked for road material and contains more numerous coarse gravel, or conglomeratic layers, than the average.
 Occurrences of the clay-bearing formation was noted in the northwestern part of the county near Friendship School, ten miles northwest of Ocala, and in two exposures three miles'northwest of Emathla, on the Tampa and Jacksonville Railroad. The thickness and extent of these deposits was not determined.
