  It 
  is 
  only 
  within 
  the 
  last 
  25 
  years 
  that 
  statistics 
  of 
  the 
  annual 
  

   production 
  have 
  been 
  recorded. 
  The 
  table 
  below 
  embraces 
  all 
  

   data 
  that 
  could 
  be 
  collected 
  from 
  published 
  sources. 
  The 
  figures 
  

   for 
  the 
  years 
  previous 
  to 
  1904 
  have 
  been 
  taken 
  principally 
  from 
  

   the 
  annual 
  reviews 
  by 
  John 
  Birkinbine, 
  contained 
  in 
  the 
  Mineral 
  

   Resources, 
  while 
  those 
  for 
  1904 
  and 
  subsequent 
  years 
  have 
  been 
  

   compiled 
  at 
  the 
  State 
  Museum.

  The 
  period 
  of 
  maximum 
  development 
  in 
  the 
  Adirondack 
  mines 
  

   may 
  be 
  said 
  to 
  have 
  extended 
  from 
  about 
  i860 
  to 
  1890. 
  In 
  the 
  

   10 
  years 
  following 
  the 
  latter 
  date 
  for 
  which 
  no 
  figures 
  are 
  available 
  

   the 
  output 
  was 
  comparatively 
  small 
  due 
  to 
  the 
  depressed 
  state 
  of 
  

   the 
  iron 
  markets 
  and 
  the 
  expansion 
  of 
  the 
  Lake 
  Superior 
  districts 
  

   which 
  were 
  able 
  to 
  sell 
  ore 
  at 
  a 
  lower 
  figure 
  than 
  was 
  possible 
  with 
  

   the 
  Adirondack 
  mines. 
  Since 
  1900 
  there 
  has 
  been 
  a 
  noticeable 
  

   improvement 
  in 
  the 
  conditions; 
  the 
  output 
  for 
  the 
  past 
  two 
  years 
  

   has 
  been 
  nearly 
  as 
  large 
  as 
  at 
  any 
  time 
  previous 
  and 
  it 
  will 
  prob- 
  

   ably 
  show 
  an 
  increase 
  for 
  the 
  next 
  few 
  years, 
  provided 
  there 
  is 
  no 
  

   marked 
  falling 
  off 
  in 
  the 
  demand 
  for 
  iron 
  ores.
