  In 
  my 
  last 
  report 
  allusion 
  was 
  made 
  to 
  the 
  fact 
  that 
  the 
  

   spruce 
  trees 
  in 
  some 
  parts 
  of 
  the 
  great 
  northern 
  wilderness, 
  

   were 
  said 
  to 
  be 
  dying 
  at 
  an 
  unusual 
  rate 
  as 
  if 
  affected 
  by 
  

   some 
  fatal 
  disease. 
  In 
  the 
  absence 
  of 
  any 
  personal 
  knowl- 
  

   edge 
  of 
  the 
  circumstances 
  or 
  conditions 
  attending 
  the 
  destruc- 
  

   tion 
  of 
  these 
  trees, 
  the 
  attacks 
  of 
  fungi, 
  the 
  attacks 
  of 
  insects 
  

   and 
  the 
  effects 
  of 
  drought 
  were 
  suggested 
  as 
  possible 
  causes, 
  

   chiefly 
  for 
  the 
  purpose 
  of 
  directing 
  the 
  attention 
  of 
  those 
  who 
  

   might 
  have 
  the 
  opportunity 
  of 
  an 
  investigation, 
  in 
  such 
  direc- 
  

   tions 
  as 
  seemed 
  most 
  likely 
  to 
  afford 
  a 
  satisfactory 
  explana- 
  

   tion 
  of 
  the 
  mystery. 
  It 
  was 
  then 
  my 
  impression 
  that 
  the 
  

   trouble 
  was 
  of 
  comparatively 
  recent 
  date 
  and 
  that 
  it 
  was 
  pos- 
  

   sibly 
  due 
  to 
  the 
  modification 
  of 
  our 
  climate 
  by 
  reason 
  of 
  the 
  

   extensive 
  and 
  rapid 
  denudation 
  of 
  our 
  forest 
  lands. 
  

  

  But 
  I 
  find 
  that 
  it 
  is 
  no 
  new 
  thing, 
  that 
  years 
  ago 
  lumbermen 
  

   were 
  fully 
  aware 
  of 
  the 
  pecuniary 
  loss 
  they 
  were 
  sustaining 
  

   from 
  this 
  timber 
  malady. 
  Mr. 
  Henry 
  Hough, 
  in 
  answer 
  to 
  my 
  

   inquiries, 
  writes 
  from 
  Lewis 
  county 
  thus 
  : 
  "The 
  dying 
  of 
  the 
  

   spruce 
  in 
  this 
  section 
  has 
  mostly, 
  if 
  not 
  entirely, 
  ceased. 
  The 
  

   greatest 
  destruction 
  on 
  our 
  territory 
  was 
  from 
  ten 
  to 
  fifteen 
  

   years 
  ago." 
  In 
  Rensselaer 
  county 
  the 
  same 
  trouble 
  was 
  

   experienced 
  about 
  thirty 
  years 
  ago. 
  A 
  lumber 
  firm 
  found 
  

   that 
  their 
  spruce 
  timber 
  was 
  rapidly 
  dying, 
  and 
  to 
  make 
  their
