  It 
  is 
  proposed 
  besides 
  mining 
  the 
  rock 
  salt 
  to 
  make 
  a 
  fine 
  

   grade 
  of 
  table 
  salt 
  by 
  artificial 
  evaporation 
  and 
  to 
  that 
  end 
  a 
  

   large 
  plant 
  is 
  to 
  be 
  erected 
  south 
  of 
  the 
  saw-mill. 
  

  

  The 
  company 
  has 
  purchased 
  a 
  tug 
  and 
  two 
  steamboats 
  and 
  

   with 
  the 
  construction 
  of 
  the 
  floating 
  elevators 
  it 
  proposes 
  to 
  

   build, 
  will 
  soon 
  become 
  a 
  very 
  active 
  factor 
  in 
  the 
  salt 
  market

  Surface 
  geology. 
  — 
  With 
  the 
  exception 
  of 
  a 
  little 
  area 
  on 
  the 
  

   eastern 
  side 
  of 
  Shaft 
  hill 
  the 
  whole 
  island 
  is 
  covered 
  with 
  grayish 
  

   yellow 
  to 
  yellowish 
  brown 
  clay. 
  The 
  clay 
  is 
  particularly 
  well 
  

   developed 
  on 
  the 
  western 
  part 
  of 
  the 
  island. 
  Southeast 
  of 
  Willow 
  

   pond 
  quite 
  a 
  number 
  of 
  springs 
  ooze 
  out 
  of 
  the 
  ground. 
  This 
  

   patch 
  of 
  ground 
  though 
  well 
  elevated 
  above 
  the 
  sea 
  marsh 
  is 
  

   covered 
  with 
  salt 
  grasses. 
  A 
  spring 
  which 
  was 
  situated 
  south 
  

   of 
  the 
  Shaft 
  house, 
  where 
  the 
  saw-mill 
  now 
  stands 
  was 
  regarded 
  

   with 
  high 
  faver 
  by 
  the 
  inhabitants 
  on 
  account 
  of 
  a 
  medicinal 
  oil 
  

   which 
  it 
  produced. 
  

  

  On 
  the 
  eastern 
  slope 
  of 
  Shaft 
  hill 
  are 
  small 
  outcrops 
  of 
  a 
  gray, 
  

   iron 
  stained, 
  rather 
  soft, 
  broken, 
  barytic 
  limestone, 
  which 
  occa- 
  

   sionally 
  shows 
  galena 
  and 
  chalcopyrite. 
  This 
  is 
  doubtless 
  the 
  

   crumbled 
  or 
  shattered 
  limestone 
  which 
  Thomassy 
  mentions* 
  and 
  

   which 
  Hilgard 
  correlated 
  with 
  the 
  C6te 
  Blanche 
  concretions, 
  f 
  

   It 
  is 
  evidently 
  quite 
  different 
  from 
  the 
  concretions. 
  This 
  lime- 
  

   stone 
  is 
  well 
  exposed 
  in 
  a 
  number 
  of 
  pits 
  dug 
  several 
  years 
  ago 
  

   by 
  the 
  U. 
  S. 
  Engineers 
  in 
  an 
  attempt 
  to 
  find 
  stone 
  suitable 
  for 
  

   jetty 
  work. 
  Near 
  by, 
  sand 
  and 
  gravel 
  come 
  to 
  the 
  surface. 
  The 
  

   gravel 
  has 
  been 
  dug 
  for 
  concrete 
  work 
  around 
  the 
  works. 
  

  

  The 
  sand 
  pit 
  fossils 
  . 
  — 
  About 
  150 
  yards 
  from 
  this 
  outcrop 
  a 
  sand 
  

   pit 
  shows 
  a 
  very 
  interesting 
  section, 
  with 
  fossils. 
  The 
  material 
  

   dips 
  about 
  23°, 
  north 
  15° 
  west.
