  the

  The

  equipped 
  with 
  a

  A

  shipped 
  to 
  glass 
  factories 
  in 
  the

  it 
  

   is 
  calcined

  IRON 
  ORE 
  

  

  The 
  iron 
  mining 
  industry 
  received 
  a 
  decided 
  setback 
  last 
  year 
  

   and 
  for 
  the 
  first 
  time 
  in 
  a 
  number 
  of 
  years 
  the 
  output 
  showed 
  a 
  

   decrease. 
  During 
  the 
  decade 
  from 
  1898 
  to 
  1907 
  the 
  State's 
  pro- 
  

   duction 
  gained 
  steadily, 
  reaching 
  a 
  total 
  of 
  1,018,013 
  long 
  tons 
  in 
  

   the 
  latter 
  year 
  as 
  compared 
  with 
  179,951 
  long 
  tons 
  in 
  1898. 
  Under 
  

   favorable 
  conditions 
  of 
  the 
  iron 
  trade 
  there 
  would 
  have 
  been 
  a 
  fur- 
  

   ther 
  increase 
  last 
  year, 
  which 
  probably 
  would 
  have 
  set 
  a 
  new 
  mark 
  

   for 
  the 
  industry 
  in 
  New 
  York. 
  Several 
  properties 
  had 
  been 
  

   brought 
  to 
  the 
  producing 
  stage 
  when 
  the 
  depression 
  began 
  and 
  

   compelled 
  a 
  suspension 
  of 
  operations. 
  With 
  the 
  contraction 
  of 
  the 
  

   market 
  the 
  operative 
  mines 
  reduced 
  their 
  output 
  and 
  a 
  few 
  closed 
  

   down 
  entirely. 
  Before 
  the 
  end 
  of 
  1908 
  conditions 
  showed 
  some 
  

   improvement, 
  though 
  it 
  can 
  hardly 
  be 
  expected 
  that 
  prosperity 
  will 
  

   be 
  fully 
  restored 
  much 
  before 
  the 
  close 
  of 
  the 
  current 
  year. 
  

  

  There 
  were 
  10 
  companies 
  which 
  reported 
  a 
  production 
  of 
  iron 
  

   ore 
  in 
  1908 
  against 
  13 
  companies 
  so 
  reporting 
  in 
  the 
  preceding 
  

   year. 
  One 
  new 
  producer, 
  the 
  Cheever 
  Iron 
  Ore 
  Co., 
  was 
  added 
  to 
  

   the 
  list, 
  so 
  that 
  out 
  of 
  the 
  number 
  of 
  active 
  companies 
  in 
  1907 
  

   four 
  were 
  closed 
  down 
  throughout 
  the 
  year. 
  

  

  The 
  accompanying 
  table 
  gives 
  the 
  production 
  of 
  iron 
  ore 
  dis- 
  

   tributed 
  according 
  to 
  kinds 
  for 
  the 
  period 
  1890-1908 
  inclusive. 
  

   The 
  statistics 
  covering 
  the 
  years 
  previous 
  to 
  1904 
  are 
  taken 
  from 
  

   the 
  annual 
  volumes 
  of 
  the 
  Mineral 
  Resources 
  published 
  by 
  the 
  

   United 
  States 
  Geological 
  Survey. 
  The 
  production 
  of 
  magnetite 
  

   as 
  given 
  in 
  the 
  table 
  represents 
  high 
  grade 
  ore 
  and 
  concentrates 
  

   suitable 
  for 
  furnace 
  use 
  and 
  not 
  the 
  mine 
  output 
  which 
  is 
  consid- 
  

   erably 
  larger 
  as 
  much 
  of 
  the 
  ore 
  is 
  concentrated.
