  — 
  Climate 
  of 
  Davis 
  1 
  and 
  Baffin' 
  *s 
  Bay. 
  

  

  and 
  decreased 
  water 
  area 
  would 
  increase 
  the 
  rigor 
  of 
  the 
  

   climate. 
  

  

  The 
  point 
  which 
  I 
  wish 
  chiefly 
  to 
  make 
  is 
  that 
  the 
  climatic 
  

   conditions 
  of 
  Baffin 
  Land 
  and 
  Labrador 
  are 
  wonderfully 
  near 
  

   those 
  which 
  produce 
  glaciation. 
  I 
  would 
  not 
  predict 
  that 
  

   these 
  lands 
  are 
  about 
  to 
  enter 
  into 
  a 
  glaciated 
  condition 
  again, 
  

   but 
  it 
  is 
  safe 
  to 
  say 
  that 
  if 
  the 
  elevation 
  now 
  in 
  progress 
  con- 
  

   tinues, 
  the 
  time 
  is 
  not 
  far 
  distant 
  when 
  valley 
  glaciers 
  will 
  

   again 
  come 
  in 
  the 
  Labrador 
  peninsula 
  and 
  when 
  those 
  of 
  Baffin 
  

   Land 
  will 
  increase 
  in 
  extent, 
  provided 
  of 
  course 
  that 
  there 
  are 
  

   no 
  general 
  changes 
  of 
  climate 
  in 
  progress, 
  the 
  nature 
  of 
  which 
  

   we 
  do 
  not 
  understand. 
  From 
  this 
  condition 
  of 
  local 
  glaciation 
  

   to 
  a 
  general 
  ice 
  sheet, 
  spreading 
  over 
  the 
  land, 
  the 
  step 
  is 
  not 
  

   great. 
  

  

  While 
  upon 
  this 
  topic, 
  and 
  in 
  conclusion, 
  it 
  may 
  be 
  pointed 
  

   out 
  that 
  in 
  addition 
  to 
  the 
  moderateness 
  of 
  the 
  summer 
  climate 
  

   of 
  the 
  Greenland 
  coast, 
  there 
  is 
  also 
  a 
  submergence 
  of 
  the 
  land 
  

   at 
  present 
  in 
  progress. 
  Topographical 
  evidence 
  of 
  this 
  is 
  plain 
  

   in 
  the 
  places 
  which 
  I 
  visited, 
  and 
  the 
  Danes 
  have 
  proved 
  the 
  

   point 
  for 
  at 
  least 
  some 
  portions 
  of 
  the 
  coast. 
  Accompanying 
  

   this 
  subsidence, 
  the 
  Greenland 
  glacier 
  has 
  recently 
  withdrawn, 
  

   at 
  least 
  from 
  the 
  land 
  of 
  the 
  Upper 
  Nugsuak 
  peninsula, 
  and 
  

   the 
  amount 
  of 
  withdrawal 
  has 
  been 
  great 
  indeed. 
  Even 
  now 
  

   the 
  ice-front 
  at 
  this 
  point 
  is 
  moving 
  backwards. 
  

  

  Is 
  Greenland 
  now 
  passing 
  through 
  the 
  stage 
  of 
  ice-with- 
  

   drawal 
  from 
  which 
  the 
  American, 
  Labrador 
  and 
  Baffin 
  Lands 
  

   have 
  so 
  recently 
  escaped 
  ? 
  and 
  is 
  there 
  any 
  relation 
  between 
  

   the 
  down-sinking 
  of 
  Greenland 
  and 
  the 
  uprising 
  of 
  Labrador 
  

   and 
  Baffin 
  Land 
  ? 
  Is 
  the 
  ice- 
  withdrawal 
  directly 
  due 
  to 
  the 
  

   land 
  movement, 
  and 
  is 
  the 
  load 
  of 
  ice 
  really 
  the 
  cause 
  for 
  the 
  

   sinking 
  which 
  allows 
  its 
  withdrawal 
  ? 
  that 
  is, 
  does 
  the 
  ice 
  

   increase 
  in 
  area 
  and 
  extent 
  with 
  no 
  other 
  result 
  than 
  its 
  own 
  

   destruction 
  by 
  depressing 
  the 
  land, 
  and 
  hence 
  removing 
  the 
  

   cause 
  of 
  supply 
  ? 
  These 
  questions 
  very 
  naturally 
  arise 
  and 
  

   others 
  even 
  more 
  speculative 
  come 
  to 
  mind 
  ; 
  but 
  as 
  their 
  answer 
  

   is 
  uot 
  definitely 
  at 
  hand 
  they 
  may 
  well 
  be 
  left 
  as 
  mere 
  queries.
