  Long, 
  near 
  Pearl 
  River, 
  eight 
  or 
  nine 
  miles 
  south 
  of 
  

   Jackson. 
  

  

  A 
  cut 
  on 
  the 
  railroad 
  between 
  Jackson 
  and 
  Brandon, 
  

   on 
  the 
  plantation 
  of 
  Mr. 
  Chambers, 
  in 
  Rankin 
  County, 
  

   also 
  exposes 
  the 
  lime-rock, 
  not, 
  however, 
  as 
  at 
  Mar- 
  

   shall's 
  or 
  Steward's 
  quarries, 
  or 
  at 
  Vicksburg, 
  in 
  a 
  con- 
  

   tinuous 
  and 
  connected 
  stratum, 
  but 
  rather 
  as 
  a 
  congeries 
  

   of 
  angular 
  disjointed 
  blocks, 
  variable 
  in 
  size 
  and 
  form, 
  

   and 
  rarely 
  of 
  dimensions 
  suitable 
  for 
  building 
  purposes, 
  

   but 
  well 
  adapted 
  for 
  burning 
  into 
  lime. 
  (See 
  Plate 
  XI., 
  

   Fig.l.) 
  

  

  Besides 
  the 
  extensive 
  use 
  made 
  of 
  this 
  rock 
  in 
  paving 
  

   the 
  streets 
  of 
  Vicksburg, 
  it 
  has 
  been 
  quarried 
  near 
  St. 
  

   Peter's 
  and 
  taken 
  to 
  Yazoo 
  City. 
  

  

  It 
  is 
  also 
  used 
  by 
  the 
  marble 
  cutters 
  in 
  Vicksburg, 
  for 
  

   monumental 
  tablets, 
  as 
  well 
  as 
  for 
  lintels, 
  door-sills 
  and 
  

   steps, 
  being 
  considered 
  as 
  equal 
  to 
  any 
  other 
  limestone 
  

   of 
  this 
  formation 
  in 
  the 
  United 
  States, 
  ordinarily 
  used 
  

   for 
  these 
  purposes. 
  

  

  On 
  the 
  recommendation 
  of 
  the 
  late 
  Edwin 
  Lyon, 
  the 
  

   sculptor 
  at 
  Natchez, 
  founded 
  on 
  the 
  examination 
  of 
  speci- 
  

   mens 
  submitted 
  to 
  him, 
  a 
  block 
  intended 
  for 
  the 
  National 
  

   Monument 
  has 
  been 
  obtained 
  from 
  Steward's 
  quarry, 
  for 
  

   the 
  Grand 
  Lodge 
  of 
  Mississippi. 
  

  

  At 
  this 
  quarry, 
  also, 
  the 
  stone 
  used 
  by 
  the 
  contractors 
  

   for 
  the 
  Lunatic 
  Asylum, 
  in 
  the 
  construction 
  of 
  that 
  

   building, 
  was 
  obtained, 
  being 
  regarded 
  as 
  greatly 
  supe- 
  

   rior 
  to 
  the 
  sandstone 
  used 
  in 
  the 
  State 
  House. 
  

  

  The 
  rock 
  at 
  Marshall's 
  is 
  of 
  equally 
  good 
  character, 
  

   but 
  the 
  facilities 
  of 
  transportation 
  not 
  being 
  equal 
  to 
  

   those 
  at 
  Steward's 
  (situated 
  immediately 
  on 
  the 
  railroad), 
  

   Mr. 
  Marshall 
  converts 
  his 
  into 
  lime. 
  

  

  In 
  the 
  further 
  prosecution 
  of 
  the 
  geological 
  survey,
