northwest boundary of the State, where it covers an area 30 or 40 
miles wide in Alabama and of about the same width in Mississippi. 
The breadth at Wetumka and thence eastward to the Georgia line is 
only a few miles. The mos.t important part of this belt is where it is 
widest, in Elmore, Bibb, Tuscaloosa, Pickens, Fayette, Marion, Lamar, 
Franklin, and Colbert counties, and the deposits are traversed by the 
ines of the Mobile and Ohio, the Alabama Great Southern, the Louis- 
ville 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. Many analyses and 
physical tests have been presented in Bulletin No. 6 of the Alabama 
Geological Survey. From this bulletin have been selected certain 
analyses which appear to indicate the fitness of the clays for cement 
making. 
In Elmore Count}^ in the vicinity of Coosada, along the banks of the 
iver, about Robinson Springs, Edgewood, and Chalk Bluff, are many 
ieposits of these clays, some of which have been used in potteries 
for many years. Analyses 13, 14, and 15, on page 70, are of clays 
: rom Coosada, Edgewood, and Chalk Bluff, respectively. 
In Bibb County clay for lire brick has been quarried very exten- 
ively at Bibbville and near Woodstock. For this purpose the mate- 
•ial is carried to Bessemer by the Alabama Great Southern Railroad. 
Analysis 16, from Woodstock, and 17, from Bibbville, will represent 
he average quality of the clay from these beds, which are very exten- 
ive both in thickness and in surficial distribution. The Mobile and 
3hio 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 trav- 
srsed by the Mobile and Ohio Railroad and by the Alabama Great 
Southern. 
Analysis 18, from Hull's, and analysis 19, from the Cribbs beds, 
re on the Alabama Great Southern, and 20 and 21 are from cuts of 
he Mobile and Ohio, a few miles west of the city of Tuscaloosa. 
Many large beds are exposed along the Mobile and Ohio road in 
ickens County also, but very few have been investigated. Analysis 
2 is from Roberts's mill, in this county. 
In Lamar and Fayette counties the same conditions prevail as in 
Pickens and Tuscaloosa. Analysis 23 is of pottery clay from the 
pribbs place, in Lamar; 24 is of clay from Wiggins's, 4 miles west 
f Fayette; 25 and 26 are clays from W. Doty's place, 14 miles west of 
hat town, in Fayette County. 
Marion is one of the banner counties of the State for tine clays, but 
J : is touched by railroads only along its southern border and in the 
xtreme northeastern corner. Although at present not available
