  immediate 
  future. 
  It 
  is 
  intended 
  eventually 
  to 
  continue 
  the 
  investi- 
  

   gations 
  so 
  as 
  to 
  provide 
  similar 
  reports 
  upon 
  the 
  other 
  districts, 
  

   thereby 
  giving 
  for 
  the 
  first 
  time 
  a 
  comprehensive 
  account 
  of 
  these 
  

   deposits 
  throughout 
  the 
  State. 
  The 
  subject 
  of 
  iron 
  ore 
  supplies 
  is 
  

   just 
  now 
  eng-aging 
  unusual 
  attention, 
  due 
  to 
  the 
  enormous 
  growth 
  

   recently 
  in 
  the 
  consumption 
  of 
  iron 
  and 
  steel 
  and 
  a 
  realization 
  of 
  

   the 
  need 
  of 
  preparing 
  to 
  meet 
  a 
  correspondingly 
  large 
  advance 
  in 
  

   the 
  years 
  to 
  come. 
  With 
  the 
  increased 
  demands 
  made 
  upon 
  the 
  

   mining 
  fields, 
  there 
  has 
  been 
  a 
  very 
  appreciable 
  falling 
  off 
  in 
  

   the 
  grade 
  of 
  the 
  ores 
  shipped 
  to 
  furnaces, 
  a 
  feature 
  that 
  is 
  bring- 
  

   ing 
  new 
  sources 
  of 
  supply 
  within 
  reach 
  of 
  practical 
  utilization. 
  

   A 
  renewed 
  interest 
  is 
  already 
  manifest 
  in 
  both 
  the 
  Adirondacks 
  and 
  

   the 
  Clinton 
  district 
  by 
  the 
  many 
  developments 
  that 
  have 
  taken 
  place 
  

   during 
  the 
  last 
  year 
  or 
  so. 
  

  

  The 
  Adirondack 
  region 
  has 
  furnished 
  altogether 
  nearly 
  40,000,- 
  

   000 
  tons 
  of 
  magnetite, 
  mainly 
  of 
  high 
  grade 
  character. 
  Wdiile 
  

   important 
  bodies 
  of 
  that 
  kind 
  still 
  remain, 
  sufficient 
  to 
  furnish 
  an 
  

   ■equivalent 
  output 
  at 
  least 
  in 
  the 
  future, 
  the 
  main 
  resources 
  consist 
  

   of 
  low 
  grade 
  ores, 
  in 
  which 
  the 
  magnetite 
  is 
  associated 
  with 
  gangue 
  

   minerals 
  and 
  which 
  require 
  concentration 
  before 
  using 
  in 
  the 
  

   furnace, 
  and 
  of 
  the 
  titaniferous 
  magnetites 
  hitherto 
  held 
  in 
  little 
  

   regard. 
  Concentration 
  is 
  already 
  being 
  practised 
  successfully 
  on 
  

   nontitaniferous 
  ores 
  carrying 
  as 
  low 
  as 
  35^^ 
  iron. 
  There 
  are 
  

   numerous 
  and 
  large 
  bodies 
  of 
  such 
  ores 
  awaiting 
  development. 
  In 
  

   the 
  report 
  attention 
  was 
  called 
  also 
  to 
  the 
  possibility 
  of 
  utilizing 
  

   the 
  titaniferous 
  magnetites, 
  as 
  some 
  careful 
  experiments 
  have 
  

   shown 
  that 
  the 
  titanium 
  can 
  be 
  partially 
  removed 
  by 
  a 
  process 
  of 
  

   concentration 
  similar 
  to 
  the 
  method 
  employed 
  for 
  the 
  other 
  magne- 
  

   tites. 
  Their 
  amenability 
  to 
  concentration 
  is 
  dependent 
  upon 
  the 
  fact 
  

   that 
  the 
  titanium, 
  in 
  many 
  cases 
  at 
  least, 
  is 
  mostly 
  segregated 
  as 
  

   ilmenite, 
  while 
  the 
  magnetite 
  carries 
  a 
  subordinate 
  amount 
  only 
  of 
  

   that 
  element. 
  If 
  concentration 
  proves 
  to 
  be 
  practicable 
  on 
  a 
  com- 
  

   mercial 
  scale, 
  there 
  is 
  no 
  doubt 
  that 
  the 
  deposits 
  will 
  come 
  into 
  

   immediate 
  use, 
  since 
  the 
  magnetites 
  aside 
  from 
  their 
  titanium 
  con- 
  

   tent 
  are 
  admirably 
  adapted 
  to 
  furnace 
  use. 
  It 
  is 
  understood 
  that 
  

   further 
  tests 
  along 
  this 
  line 
  are 
  in 
  progress 
  with 
  reference 
  to 
  the 
  

   Lake 
  Sanford 
  ore 
  bodies 
  which 
  have 
  recently 
  been 
  explored 
  with 
  

   highly 
  satisfactory 
  results. 
  

  

  The 
  report 
  on 
  the 
  Clinton 
  ores 
  includes 
  a 
  number 
  of 
  new 
  sections 
  

   showing 
  the 
  occurrence 
  and 
  stratigraphic 
  relations 
  of 
  the 
  ore 
  seams 
  

   •over 
  a 
  portion 
  of 
  the 
  belt 
  hitherto 
  unexplored. 
  These 
  sections 
  were 
  

   prepared 
  from 
  the 
  records 
  of 
  drill 
  holes 
  put 
  down 
  during 
  the 
  fall
