  The 
  average 
  

   rate 
  of 
  migration 
  from 
  central 
  Montana, 
  April 
  6, 
  to 
  Mercy 
  Bay, 
  May

  is 
  33 
  miles 
  per 
  day. 
  

  

  During 
  spring 
  migration 
  there 
  is 
  much 
  difference 
  in 
  the 
  length 
  of 
  

   time 
  spent 
  at 
  different 
  points 
  of 
  its 
  route. 
  In 
  northern 
  Texas 
  the 
  first 
  

   appear 
  March 
  1 
  and 
  the 
  last 
  leave 
  April 
  6, 
  each 
  being 
  average 
  dates; 
  

   the 
  extremes 
  are 
  February 
  18, 
  1887, 
  and 
  April 
  12, 
  1895; 
  in 
  other 
  

   words, 
  the 
  snow 
  goose 
  is 
  usually 
  thirty-three 
  days 
  in 
  passing 
  northern 
  

   Texas, 
  and 
  ma} 
  7- 
  linger 
  fifty-four 
  days. 
  At 
  the 
  northern 
  boundary 
  of 
  

   the 
  United 
  States, 
  these 
  periods 
  are 
  reduced 
  about 
  one-third, 
  while 
  

   still 
  farther 
  north 
  near 
  Lake 
  Athabasca 
  the 
  species 
  was 
  present 
  in 
  1901 
  

   for 
  at 
  least 
  fourteen 
  days, 
  in 
  1903 
  for 
  fifteen 
  days, 
  and 
  at 
  Fort 
  Simp- 
  

   son 
  in 
  1904 
  for 
  twenty 
  -three 
  days. 
  They

  Fall 
  migration. 
  — 
  Early 
  migrants 
  of 
  the 
  lesser 
  snow 
  goose 
  were 
  

   noted 
  at 
  Parry 
  Bay, 
  latitude 
  72°, 
  August 
  13, 
  1821; 
  at 
  Point 
  Barrow, 
  

   latitude 
  70°, 
  August 
  15, 
  1883; 
  at 
  Darnley 
  Bay, 
  latitude 
  69°,

   17, 
  1848; 
  St.

  Terry,

   latitude

  September 
  12, 
  1904; 
  Stockton, 
  Cal., 
  latitude 
  38°, 
  about 
  

   September 
  29; 
  central 
  Texas, 
  latitude 
  31°, 
  about 
  October 
  11. 
  These 
  

   dates 
  indicate 
  that 
  the 
  most 
  northern 
  breeders 
  do 
  not 
  remain 
  so 
  long- 
  

   as 
  ten 
  weeks 
  on 
  the 
  breeding 
  grounds, 
  and 
  that 
  they 
  occup} 
  T 
  fifty-eight 
  

   days 
  in 
  retracing 
  the 
  path 
  that 
  required 
  sixty-eight 
  days 
  during 
  the 
  

   spring 
  migration. 
  

  

  The 
  last 
  seen 
  on 
  Banks 
  Land 
  were 
  noted 
  September 
  7, 
  1850; 
  near 
  Fort 
  

   Norman, 
  October 
  3, 
  1903; 
  at 
  mouth 
  of 
  the 
  Yukon, 
  about 
  October 
  10; 
  

   ten 
  days 
  later 
  the 
  last 
  cross 
  the 
  boundary 
  of 
  the 
  United 
  States 
  to 
  the 
  

   Mississippi 
  watershed 
  and

  Breeding 
  range. 
  — 
  The 
  greater 
  snow 
  goose 
  is 
  enormously 
  abundant 
  

   on 
  both 
  the 
  eastern 
  and 
  the 
  western 
  shores 
  of 
  Hudson 
  Bay 
  during 
  

   spring 
  migration, 
  and 
  these 
  birds 
  might 
  be 
  supposed 
  to 
  pass 
  from 
  

   these 
  points 
  approximately 
  north 
  to 
  their 
  breeding 
  grounds. 
  If 
  such 
  

   is 
  the 
  case 
  it 
  is 
  somewhat 
  strange 
  that 
  they 
  have 
  never 
  been 
  found 
  

   breeding 
  on 
  any 
  of 
  the 
  northern 
  islands; 
  nor 
  have 
  they 
  been 
  noted 
  in 
  

   migration 
  anywhere 
  north, 
  northeast, 
  or 
  east 
  of 
  Hudson 
  Bay, 
  except 
  

   the 
  few 
  seen 
  at 
  Igloolik, 
  a 
  few 
  noted 
  by 
  Kumlein 
  in 
  Cumberland 
  Bay, 
  

   some 
  stragglers 
  that 
  have 
  wandered 
  to 
  the 
  west 
  coast 
  of 
  Greenland, 
  and 
  

   thiee 
  birds 
  seen 
  by 
  Greeley's 
  party 
  June 
  12-13, 
  1882, 
  in 
  Grinnell 
  

   Land, 
  latitude 
  82°. 
  As 
  alread}^ 
  stated 
  in 
  connection 
  with 
  the 
  lesser 
  

   snow 
  goose, 
  it 
  is 
  probable 
  that 
  these 
  Hudson 
  Bay 
  geese 
  eventually
