76 GEOLOaiGAL RELATIONS OF ALABAMA CLAYS. 



In Cherokee county, to ffche northward of the line 

 of the Southern Railroad in Sections 1 and 2 of T. 12, 

 R. 11, E., there are many banks of limonite which 

 have been extensively worked, and in some of 

 them beds or "horses" of white clay have 

 been exposed. One of these in the Clay limonite 

 bank, in Section 2, Ithe clay deposit is of great extent 

 and several car loads have been taken from it and 

 shipped to Chattanooga for manufacturing into fire 

 brick. A similar white clay occurs in the Hickory 

 Tree bank in Section 1, ( p. 759. ) The occurrence of 

 the clay in the Dy^e limonite bank, near Rock Run, 

 is described on page 777. This is Itihe kaolin whose 

 analysis is given below under the number A. S. In 

 the Washer bauxite band in S. 35, T. 12, R. 11 E., 

 near Rock Run, and in the Warwhoop and other 

 bauxite banks of the same vicinity, white clay 

 and halloysite are of common occurrence. Some 

 of these clays should be utilized. 



Some details concerning Ithem are to be found in 

 the Valley Regions report, pages 780 to 789. 



In the limonite banks to the eastward of Tecumseh 

 furance in the same county, in T. 12, R. 12, E., clay 

 "horses" are everywhere found separating the pock- 

 ets of limonite, pages 792 and 793. 



Accumulaltions of good plastic clay, which have 

 evidently been deposited in the depressionsi of the 

 limestone or in ponds, are not uncommon in the area 

 of the great limestone formations. One such near- 

 Oxford in Calhoun county, is utilized by the Dixie 

 Tile and Pottery Company. Analysis and physical 

 tests of this clay are given in the body of this report. 



Of less purity on account of mixtures of sand, etc., 

 similar deposits are numerous, and utilized in 

 places, as, for example, the brick clay at DeArman- 

 ville in the Choccolocco valley.
