A dense, gray, plastic clay is of rather widespread occurrence in the 
region about Quintette. An extension or outlier of what is probably 
this same deposit is exposed at the upper end of Lower Dexland Bluff. 
It underlies both the hill just west of Quintette station and the one about 
one quarter-mile northward. It was also observed on the property of 
S. J. Baumeister, one-half mile west of Quintette. A section made at 
the Barrineau Bros. Brick Company’s plant at Quintette is as follows:

Section of Barrineau Bros. Brick Company Clay Pit, Quintette. 
In many places the limonite overlies a cross-bedded sand. 
The Barrineau Bros. Brick Company use this clay for the manu¬ 
facture of face and common brick and turpentine cups. Their plant is 
located on the Pensacola Division of the Louisville and Nashville Rail¬ 
road. The product is marketed chiefly in western Florida, southern Ala¬ 
bama, Mississippi and Louisiana. Mobile and Pensacola absorb the 
greater part of the output. The First Baptist Church in Pensacola was 
built of this brick. 
This clay may be used for terra-cotta, stoneware, roofing tile, flower 
pots, as well as the common structural materials. 
This is not a red-burning clay as would be anticipated from its 
association with limonite, but a very light-pink at cones 010 and 05 and 
grades into buff, gray and grayish-brown as the temperature is increased. 
The physical properties are as follows:
