CRETACEOUS FORMATION. 107 



Dr. Little and analyzed by Dr. Ries, (numbers 12, 

 40 S. and 41 S.). The bed in this region is about 

 four feet in thickness. Nos. 12 and 40 are from H. 

 Palmer's and X<>. 41 from Bexar, a mile further west, 

 near Pearce's Store and Mill. 



Near the State line on <tlie road to Tremont, Miss., 

 twenty feet thickness of clay is reported as being cut 

 in a well. 



Beyond the State line, the clays continue, and at 

 Davidson's Store, Lloyd's pottery, they are put 'to a 

 rather remarkable use, namely for head stones of 

 graves, for which purpose they are moulded into flat 

 tablets, provided with suitable inscriptions and then 

 baked. These stones appear to be quite durable al- 

 though necessarily lia*ble to be broken. 



A number of potteries in this vicinity use this clay 

 which is about four feet in thickness, and. quite 

 similar to that mentioned above as occurring about 

 Gattman in Lamar county, on the K. C. M. & B. Rail- 

 road. 



The Bexar variety of clay extends for a good many 

 miles northward up Hurricane Fork and along Bull 

 Mountain Creek. 



FRANKLIN COUNTY. 



In Franklin county the underlying Paleozoic rocks 

 of Carboniferous and Subcarboniferous ages are ex- 

 posed along the valleys of the streams, but every- 

 where else are covered with a mantle of varying 

 thickness of the sands, clays and pebbles of the Tus- 

 caloosa and Lafayette formations. 



As in the other counties adjoining towards the 

 south, so in this, it is in the Tuscaloosa strata that we 

 find the important deposits of clay. In parts of the 

 county, especially in the vicinity of Eussellville, val-
