smith]  CEMENT    RESOURCES    OF    ALABAMA.  431 
potteries  for  many  years.  Analyses  13,  14  and  15,  on  p.  433,  are  of 
clays  from  Coosada,  Edgewood,  and  Chalk  Bluff,  respectively. 
In  Bibb  County  clay  has  been  quarried  very  extensively  at  Bibb- 
ville  and  near  Woodstock  for  making  fire  brick.  For  this  purpose  the 
material  is  carried  to  Bessemer  by  the  Alabama  Great  Southern  Rail- 
road. No.  16,  from  Woodstock,  and  17,  from  Bibbville,  will  represent 
the  average  quality  of  the  clay  from  these  beds,  which  are  very  exten- 
sive both  in  thickness  and  in  superficial  distribution.  The  Mobile  and 
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  trav- 
ersed by  the  Mobile  and  Ohio  Railroad  and  by  the  Alabama  Great 
Southern. 
Analysis  18,  from  Hull's,  and  analysis  19,  from  the  Cribbs  beds, 
are  on  the  Alabama  Great  Southern,  and  20  and  21  are  from  cuts  of 
the  Mobile  and  Ohio,  a  few  miles  west  of  the  city  of  Tuscaloosa. 
Many  large  beds  are  exposed  along  the  Mobile  and  Ohio  road  in 
Pickens  County  also,  but  very  few  have  been  investigated.  No.  22  is 
from  Roberts  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 
Cribbs  place,  in  Lamar,  and  No.  24  is  of  clay  from  Wiggins's,  4  miles 
west  of  Fayette,  and  25  and  26  are  clays  from  W.  Doty's  place,  14 
miles  west  of  that  town,  in  Fayette  Count}^ 
Marion  is  one  of  the  banner  counties  of  the  State  for  fine  clays,  but 
it  is  touched  by  railroads  only  along  its  southern  border  and  in  the 
extreme  northeastern  corner.  Although  at  present  not  available 
because  inaccessible,  the  clays  mentioned  below  are  worthy  of  con- 
sideration: No.  27,  from  Bexar;  No.  28,  from  Briggs  Fredericks',  in 
sec.  8,  T.  10,  R.  13  W.  This  is  from  the  great  clay  deposit  which 
gives  the  name  to  Chalk  Bluff  and  which  underlies  about  two  town- 
ships. No.  29  is  from  a  locality  about  16  miles  southwest  of  Hamil- 
ton, the  county  seat. 
No.  30  is  from  a  localit}^  near  the  Mississippi  line,  in  sec.  20,  T.  8, 
R.  15  W.,  in  Franklin  County,  from  land  of  Mr.  Thomas  Rollins. 
Of  the  numerous  fine  clays  of  Colbert  Count}^  analyses  are  given  of 
two  from  Pegram  station,  on  the  Southern  Railway  near  the  Missis- 
sippi State  line.     These  are  Nos.  31  and  32.
