  The 
  Bulletin 
  contains 
  also 
  11 
  tables, 
  showing 
  in 
  detail 
  various 
  

   features 
  of 
  the 
  salt 
  and 
  gypsum 
  industries. 
  It 
  is 
  illustrated 
  by 
  

   12 
  plates. 
  The 
  Assistant 
  Director 
  experienced 
  great 
  difficulty 
  

   in 
  securing 
  satisfactory 
  specimens 
  of 
  salt 
  for 
  display. 
  Mr. 
  E. 
  

   D. 
  White, 
  C. 
  E., 
  was 
  first 
  sent 
  out 
  to 
  visit 
  the 
  manufacturers 
  of 
  

   salt 
  in 
  the 
  State, 
  and 
  to 
  select 
  and 
  arrange 
  for 
  the 
  shipment 
  of 
  

   the 
  different 
  kinds 
  of 
  salt. 
  The 
  companies 
  did 
  not 
  feel 
  that 
  the 
  

   exhibits 
  would 
  be 
  of 
  financial 
  value 
  to 
  them, 
  and 
  were 
  reluctant 
  

   to 
  involve 
  themselves 
  in 
  any 
  expenditure 
  of 
  time 
  or 
  labor. 
  It 
  

   became 
  necessary 
  to 
  send 
  Mr. 
  William 
  C. 
  Clarke, 
  E. 
  M., 
  on 
  an 
  

   additional 
  trip 
  before 
  satisfactory 
  arrangements 
  could 
  be 
  made 
  

   to 
  present 
  a 
  proper 
  exhibit. 
  

  

  The 
  study 
  of 
  the 
  gypsum 
  industry- 
  had 
  already 
  been 
  placed 
  in 
  

   the 
  hands 
  of 
  Mr. 
  Clarke, 
  who 
  ably 
  conducted 
  the 
  examination. 
  

   The 
  value 
  of 
  this 
  industry 
  is 
  considered 
  in 
  the 
  same 
  report. 
  

  

  The 
  building 
  stones 
  of 
  the 
  State 
  were 
  prepared 
  for 
  exhibition 
  

   in 
  ten-inch 
  cubes, 
  one 
  face 
  receiving 
  as 
  high 
  a 
  polish 
  as 
  the 
  stone 
  

   was 
  susceptible 
  of, 
  and 
  the 
  other 
  faces 
  being 
  prepared 
  so 
  as 
  to 
  

   bring 
  out 
  the 
  individual 
  peculiarities 
  of 
  the 
  stone. 
  The 
  work 
  of 
  

   cutting 
  and 
  polishing 
  ' 
  these 
  stones 
  was 
  done 
  by 
  the 
  firm 
  of 
  

   Schilling 
  & 
  Co., 
  of 
  Albany, 
  who 
  also 
  prepared 
  the 
  stones 
  for 
  the 
  

   geological 
  obelisk. 
  

  

  A 
  prominent 
  feature 
  of 
  the 
  mining 
  exhibit 
  was 
  an 
  obelisk 
  of 
  

   stone 
  from 
  the 
  various 
  geological 
  formations 
  of 
  J^ew 
  York, 
  

   arranged 
  in 
  layers 
  of 
  proportionate 
  thickness, 
  on 
  a 
  scale 
  of 
  fifty 
  

   feet 
  to 
  the 
  inch, 
  and 
  of 
  which 
  the 
  proportions 
  are 
  those 
  of 
  

   Cleopatra's 
  needle, 
  in 
  Central 
  Park. 
  The 
  idea 
  of 
  a 
  geological 
  

   column 
  was 
  first 
  suggested 
  by 
  Prof. 
  Hall, 
  who 
  exhibited 
  a 
  

   pyramid 
  at 
  the 
  E"ew 
  Orleans 
  exposition 
  in 
  1885-0, 
  but 
  it 
  was 
  

   found 
  advisable 
  by 
  the 
  Assistant 
  Director 
  to 
  adopt 
  a 
  form 
  and 
  

   plan 
  different 
  from 
  that 
  of 
  Dr. 
  Hall, 
  and 
  the 
  proportions 
  of 
  the 
  

   Egyptian 
  obelisk 
  were 
  chosen, 
  as 
  exhibiting 
  greater 
  eLegance 
  of 
  

   form, 
  and 
  being 
  more 
  economical 
  of 
  ground 
  space. 
  The 
  geologi- 
  

   cal 
  obelisk 
  was 
  composed 
  of 
  all 
  the 
  solid 
  rock 
  formations 
  occur- 
  

   ring 
  in 
  New 
  York, 
  in 
  their 
  regular 
  succession, 
  from 
  the 
  Archaean 
  

   to 
  the 
  summit 
  of 
  the 
  Trias. 
  The 
  four 
  sides 
  of 
  the 
  obelisk 
  show 
  

   the 
  occurrence 
  of 
  the 
  formations 
  in 
  the 
  respective 
  quarters 
  of 
  

   the 
  State, 
  each 
  formation 
  being 
  represented 
  by 
  one 
  or 
  more
