A PRELIMINARY REPORT ON CLAYS OE ELORIDA

twelve or fifteen feet and are interbedded with sands and sandy clays. 
Thin lentils of clay often appear in the sand. A given stratum of this 
clay may be distributed over a wide area, yet it may not be continuous 
throughout this region. Its thickness may vary and in places it may dis¬ 
appear altogether, owing at times to non-deposition, but in most places 
to subsequent erosion. 
The following section at Gull Point will be illustrative of the gen¬ 
eral region, but it is to be noted that the intervals between the various 
strata are variable: 
Section at Gull Point, Escambia Bay. 
Soil . 2 feet. 
Clay, gray, jointed, Gull Point No. 1 (Lab. Sample No. 0-49) . . . .. 4 feet.

Clay, red, very plastic, Gull Point No. 3 (Lab. Sample No. 0-31). 4 feet. 
Sand, cross-bedded, with some clay lentils. ? 
A boring made near Ninth Avenue and Marino Street in the City of 
Pensacola indicated the following section:

This section was made at the site of the Kohler Pottery, formerly 
operated in Pensacola, and is only about two' miles from the Gull Point 
section. The uppermost gray plastic clay was used in the manufacture 
of jugs and similar articles of stoneware. This bed is exposed about a 
half block northeastward in an excavation made by the city of Pensacola 
and corresponds in appearance and properties to the Gull Point clay No. 
2 (Lab. Sample No. 0-2) and is probably the same stratum. The Gull 
Point clay No. 3 (Lab. Sample No. 0-31) is here split into two thin 
layers of six inches each separated by a coarse, gray, sandy clay four feet 
in thickness. Gull Point clay No. 1 is not exposed here. 
At Dexland Bluff, property of Chas. A. Dexter, on the Escambia 
River opposite Gonzales, about ten miles north of Pensacola, a similar
