  week 
  of 
  that 
  month, 
  generally 
  about 
  the 
  middle 
  of 
  the 
  week 
  ; 
  its 
  north- 
  

   ward 
  progress 
  being 
  apparently 
  hastened 
  or 
  retarded 
  by 
  the 
  mildness 
  of 
  

   the 
  season. 
  They 
  seem 
  always 
  to 
  wait 
  for 
  the 
  flowering 
  of 
  a 
  species 
  

   of 
  horse-chesnut, 
  called 
  here, 
  the 
  Buckeye, 
  from 
  the 
  fancied 
  likeness 
  

   of 
  its 
  fruit 
  to 
  the 
  eyes 
  of 
  a 
  deer. 
  The 
  bright 
  red 
  blossoms 
  of 
  this 
  tree 
  

   supply 
  the 
  nourishment 
  most 
  attractive 
  to 
  these 
  birds, 
  whose 
  arrival 
  had 
  

   been 
  looked 
  for, 
  the 
  very 
  day 
  after 
  I 
  came. 
  Strange 
  to 
  say, 
  one 
  of 
  them, 
  

   the 
  avant-courier 
  of 
  the 
  feathered 
  host, 
  actually 
  appeared 
  and 
  next 
  

   morning, 
  (May 
  7, 
  1846,) 
  hundreds 
  were 
  seen 
  and 
  heard, 
  flitting 
  and 
  

   humming 
  over 
  our 
  heads."
