ORE    DEVELOPMENTS    OF    THE    DISTRICT. 
The  Clinton  ores  have  been  carefully  traced  throughout  this  district  by  Dr.  C.  W.  Hayes 
and  the  writer,  and  in  the  final  report  large-scale  maps  will  be  included,  showing  the  exact 
location  of  the  ore-bearing  formation.  Since  such  maps  can  not  be  presented  here,  atten- 
tion will  be  confined  to  a  description  of  the  developed  ore  deposits  of  the  region.  These  will 
be  described  in  geographical  order,  from  Battelle  south  to  Attalla,  after  which  the  chief 
facts  concerning  the  Gadsden  and  Gaylesville  deposits  will  be  briefly  noted. 
Battelle. — The  mines  of  the  Ragon  Mining  Company,  which  supply  the  furnace  of  the 
Lookout  Mountain  Iron  Company  at  Battelle,  are  located  about  one-fourth  mile  west  oft 
the  furnace,  on  the  northwest  side  of  Red  Mountain.  Four  ore  beds  arc  shown  in  the  section 
here,  with  following  dips  and  thicknesses  and  approximate  distances  apart:

Of  these  beds,  however,  the  second  is  too  sandy  to  be  workable  and  the  third  seems  to 
be  a  very  local  development  which  can  not  he  traced  many  feel  from  its  outcrop.  The 
fust  of  top  hed  is  worked  by  three  slopes,  each  of  which  is  nov  down  about  200  feel ;  the 
fourth  bed  has  two  small  and  almost  vertical  openings. 
The  soft  ore  has  been  practically  worked  out,  and  th  mines  are  now  entirely  in  a  hard 
very  limy  ore.  The  following  analyses,  by  Mr.  I.  P.  Todd,  chemist  of  the  Lookout  Moun- 
tain Iron  Company,  w  ill  serve  to  show  the  range  in  composition  of  the  ore  from  the  difl'erent 
beds  and  slopes:
