  The 
  character 
  of 
  the 
  Cretaceous 
  limestone 
  here 
  exposed 
  is 
  

   such 
  as 
  to 
  render 
  it 
  almost 
  useless 
  as 
  a 
  building 
  or 
  ornamental 
  

   stone, 
  but 
  it 
  can 
  be 
  used 
  to 
  advantage 
  for 
  making 
  lime. 
  It 
  is 
  

   full 
  of 
  cracks, 
  pockets 
  and 
  joints 
  ; 
  is 
  highly 
  crystalline 
  and 
  

   shows 
  whitish 
  and 
  bluish 
  bands 
  of 
  various 
  shades 
  of 
  color. 
  So 
  

   far 
  no 
  fossils 
  have 
  been 
  observed 
  in 
  these 
  crystalline 
  limestone 
  

   ledges. 
  - 
  

  

  The 
  Lower 
  Claiborne 
  limestone 
  is 
  of 
  a 
  yellowish 
  or 
  reddish 
  

   white 
  color, 
  far 
  less 
  crystalline 
  and 
  very 
  fossiliferous.

  Pi.

  was 
  taken 
  just 
  south 
  of 
  the 
  limestone 
  outcrop 
  in 
  the 
  

   direction 
  indicated 
  by 
  the 
  large 
  arrow 
  (see 
  Fig. 
  4). 
  

  

  Here 
  there 
  is 
  a 
  northwestern 
  quarter 
  of 
  a 
  dome-like 
  upheaval 
  

   well 
  exposed. 
  To 
  the 
  east 
  is 
  what 
  appears 
  to 
  be 
  a 
  less 
  

   marked, 
  or 
  lower 
  structure 
  of 
  similar 
  nature 
  still 
  hidden 
  beneath 
  

   the 
  surface 
  soil. 
  Their 
  location 
  and 
  general 
  relations 
  to 
  each 
  

   other 
  are 
  likewise 
  shown 
  on 
  the 
  sketch-map, 
  Fig. 
  4. 
  

  

  This 
  limestone 
  is 
  more 
  arenaceous 
  or 
  sandy 
  in 
  appearance 
  

   than 
  that 
  at 
  Winnfaeld 
  ; 
  but 
  is 
  of 
  a 
  most 
  excellent 
  quality 
  for 
  

   building 
  purposes. 
  Its 
  beauty 
  as 
  building 
  material 
  is, 
  however,
