BDRCHABD.l      IRON    ORES    IN    BROOK  WOOD    QUADRANGLE,    ALA.  325 
Seventy-five  yards  southwest  of  this  cut  is  a  test  pit,  in  which  were 
found  two  beds  of  ore,  each  about  5  feet  thick,  separated  by  about  10 
feet  of  sandstone  and  debris.  These  beds  dip  about  75°  toward  the 
northwest,  and  the  lower  one,  which  is  very  sandy,  is  said  to  thin 
down  to  about  one  foot  within  a  few  hundred  feet  along  the  dip. 
Prospecting*  near  the  southwest  corner  of  section  3  is  reported  to 
have  disclosed  two  beds  of  impure  ore,  of  5  and  2  feet  thickness. 
In  the  NE.  i  of  SW.  i  sec.  9,  T.  21  N.,  R.  G.  W.,  on  the  south  side 
of  Gallant  Creek,  the  formation  occurs  on  both  sides  of  a  narrow 
hollow,  on  both  sides  of  which  test  pits  have  been  sunk.  On  the 
southeast  side  of  the  hollowT  about  10  feet  of  shaly,  sandy  ore  is 
shown  by  one  pit,  while  on  the  northwest  side  more  than  30  feet  of 
ore  is  disclosed,  most  of  it  being  a  dark  ferruginous  sandstone.  A 
corresponding  thickness  of  ferruginous  material  is  indicated  by  a  pit 
in  the  SE.  ±  of  SE.  i  sec.  8,  T.  21  N.,  R.  6  W.,  but  (he  greater 
part  of  it  does  not  promise  to  be  valuable.  Southwest  of  sec.  IT  the 
formation  disappears  in  places,  through  faulting.  In  the  NW.  \  of 
NE.  \  sec.  25,  T.  21  N.,  R.  7  W.,  several  deep  pits  have  been  sunk 
into  ore-bearing  strata,  but  thicknesses  of  only  2  to  5  feet  were 
observed,  and  the  ore  was  streaked  and  parted  with  clay  and  shale. 
In  the  portion  of  the  strip  thus  far  described  the  showing  of  ore 
does  not  seem  to  be  sufficiently  valuable  to  encourage  mining  under 
present  conditions. 
At  Vance  the  formation  again  outcrops,  and  apparently  carries 
a  workable  seam  of  ore.  A  shaft  sunk  about  100  yards  north  of 
the  station  goes  down  170  feet  in  nearly  vertical  ore  having  a  lime- 
stone wall  to  the  south.  Ore  has  been  shipped  from  this  place  to 
he  furnace  of  the  Central  Iron  and  Coal  Company  at  Holt,  Ala., 
but  in  the  autumn  of  1904  the  property  was  idle  and  the  shaft  was 
filled  with  water.  A  reported  analysis  of  this  ore,  which  is  well 
leached   and   consequently   soft,   as   published   by   McCalley,"    is   as 
follows :

The  rocks  in  this  vicinity  have  been  much  faulted,  and  their  dis- 
turbed condition  is  shown  in  the  limestone  quarry  at  Vance.  To  the 
southwest  of  Vance  the  Rockwood  formation  is  offset  to  the  west  by 
faulting,  and  a  strip  has  been  traced  by  outcrops  and  prospects  from 
the  Alabama  Great  Southern  Railroad  at  Hurricane  Creek  trestle, 
west  of  Vance,  southwestward  for  about  4  miles.     There  is  a  bed  of
