108 GEOLOGICAL RELATIONS OF ALABAMA CLAYS. 



liable deposits of limonite or brown iron ore have 

 been for many years and are now being worked to 

 supply the furnaces at Sheffield and Florence. 



Associated with these ore beds are clay horses, 

 as they are called,, which, in places, yield an abun- 

 dance of fine white clay.* 



Other occurrences of the clays of the Tuscaloosa 

 formation, not associated with the iron ores, have 

 been recorded by Dr. Little, from whose notes the fol- 

 lowing details have been obtained. 



On the southern boundary of the county, near Sa- 

 voy postoffice, in T. 8, E. 14, near Dr. Kilgore's Mill, 

 a bed of blue plastic clay three feet thick is noted, 

 above which, one hundred feet up the hill, is a bed of 

 four feet thickness of red clay^or ochre (re,d chalk), 

 and just above this a bed four feet thick of pure, hard, 

 white clay, like that of Chalk Bluff, in Marion coun- 

 ty. The same beds are to be seen at many points 

 around Savoy within a radius of three miles. Half 

 a mile west of Burleson a bed three feet in thickness 

 of white clay is found immediately overlying the blue 

 limestone of the Subcarboniferous formation. Along 

 the road from Burleson to Belgreen the clay is ex- 

 posed at several points. 



Northwest of Russellville, on the road to Frank- 

 fort, large deposits of white clay were reported, but 

 not seen by Dr. Little. 



Near the State line, in S. 9, T. 7, R, 15, on Gilley's 

 branch, occurs a bed of clay from which material 'has 

 been obtained for a pottery formerly worked by Mr. 

 Chaney, two miles east of Pleasant Ridge, Miss. 



Southward of this locality, in S. 20 and S. 29, of 

 T. 8, R, 15, Mr. Thomas Rollins has a bed of clay four
