Bibb. Tuscaloosa, Pickens, Fayette, Marion, Lamar, Franklin, 

 and Colbert counties, and the deposits are traversed by the lines 

 of the Mobile and Ohio; the Alabama Great Southern; the 

 Louisville and Nashville; the Southern; and the Kansas City, 

 Memphis and Birmingham railroads ; as well as by the Warrior 

 and Tombigbee rivers. 



These clays have been described in some detail, and many 

 analyses and physical tests have been presented in the Bulletin 

 No. 6 of the Alabama Geological Survey. From this bulletin 

 have been selected the analyses which appear to indicate the 

 fitness of the clays for cement making. 



In Elmore county, in the vicinity of Coosada, along the banks 

 of the river, about Robinson Springs, Edgewood, and Chalk 

 Bluff, there are many occurrences of these clays, some of which 

 have been used in potteries for many years. Analyses 15, from 

 Coosada; 16, from Edgewood; and 17, from Chalk Bluff, are 

 given in the table D. 



In Bibb county the clay has been quarried viery extensively at 

 Bibbville and near Woodstock for making fire brick. For this 

 purpose the material is carried to Bessemer by the Alabama 

 Great Southern Railroad. No. 18, from Woodstock; and 19, 

 from Bibbville, will represent the average quality of the clay 

 from these beds, which are very extensive, both in thickness 

 and in superficial distribution. The Mobile & Ohio crosses 

 other extensive deposits in the southern part of the county, but 

 no analyses are available. 



The most important of the clay beds in Tuscaloosa county 

 are traversed by the Mobile & Ohio Railroad and by the Ala- 

 bama Great Southern. 



Analysis 20, from Hull's; and analysis 21, from the Cribbs 

 beds, are on the Alabama Great Southern; and 22 and 23 are 

 from cuts of the Mobile & Ohio, a few miles west of the city of 

 Tuscalcosa. 



Many large beds are exposed along the Mobile & Ohio road 

 in Pickens county also, but very few haive been as yet investi- 

 gated. No. 24 is from Roberts Mill, in this county. 



In Lamar and Fayette counties the same conditions prevail as 

 in Pickens and Tuscaloosa, Analysis 25 is of pottery clay from 

 the Cribbs place, in Lamar ; and No. 26 is of clay from Wig- 

 gins's, 4 miles west of Fayette ; and 27 and 28 are clays from 

 W. Doty's place, 14 miles west of that town, in Fayette county.
