  the 
  principal 
  subdivisions 
  be 
  treated

  meets 
  the

   In

  the

  the

  Informal 
  communication 
  

  

  Dr. 
  F. 
  H. 
  KnowlTON 
  stated 
  that 
  during 
  the 
  last 
  ten 
  years, 
  for 
  three 
  of 
  the 
  

   spring 
  months, 
  continuously 
  during 
  the 
  daylight 
  hours 
  a 
  cardinal 
  would 
  

   fight 
  his 
  reflection 
  in 
  the 
  windows 
  of 
  the 
  speaker's 
  house. 
  The 
  bird 
  has 
  been 
  

   known 
  to 
  launch 
  himself 
  at 
  the 
  windows 
  26 
  times 
  in 
  five 
  minutes. 
  It 
  is 
  not 
  

   known 
  that 
  it 
  is 
  the 
  same 
  bird 
  which 
  has 
  been 
  under 
  observation 
  during 
  these 
  

   years.

  F. 
  H. 
  Knowlton: 
  The 
  flora 
  of 
  some 
  newly 
  discovered 
  beds 
  in 
  southern 
  

   Colorado. 
  

  

  For 
  fifty 
  years 
  highly 
  fossiliferous 
  deposits 
  have 
  been 
  known 
  in 
  the 
  Tertiary 
  

   lake 
  beds 
  of 
  Florissant, 
  Colorado. 
  Insects, 
  plants, 
  and 
  birds, 
  fish 
  and 
  shells 
  

   are 
  preserved 
  with 
  remarkable 
  fidelity 
  in 
  the 
  volcanic 
  ashes 
  and 
  mud 
  filling 
  

   the 
  lake. 
  Other 
  similar 
  deposits 
  have 
  been 
  found 
  in 
  Colorado, 
  the 
  largest 
  

   near 
  Creede. 
  Among 
  the 
  plants 
  found 
  are 
  pines, 
  firs, 
  grape, 
  currant, 
  poplars, 
  

   flowers 
  and 
  fruit 
  believed 
  to 
  be 
  a 
  raspberry, 
  etc. 
  Specimens 
  were 
  shown 
  

   in 
  the 
  thin 
  papery 
  shales 
  into 
  which 
  the 
  rock 
  breaks 
  up. 
  The 
  paper 
  was 
  

   discussed 
  by 
  Messrs. 
  Rohwer, 
  Hopkins, 
  and 
  Hitchcock. 
  

  

  H. 
  C. 
  Oberholser: 
  The 
  breeding 
  water 
  fowl 
  of 
  the 
  Great 
  Plains 
  region. 
  

  

  For 
  several 
  j^ears 
  the 
  breeding 
  grounds 
  of 
  water 
  fowl 
  in 
  the 
  United 
  vStates 
  

   were 
  studied 
  by 
  the 
  Biological 
  Survey 
  to 
  secure 
  data 
  for 
  the 
  administration 
  

   of 
  game 
  protection 
  laws. 
  The 
  greatest 
  breeding 
  ground 
  in 
  the 
  United 
  vStates 
  

   is 
  in 
  the 
  State 
  of 
  Nebraska 
  and 
  the 
  States 
  northerly 
  from 
  it. 
  Still 
  greater 
  

   areas 
  exist 
  in 
  Canada. 
  For 
  many 
  years 
  the 
  water 
  fowl 
  suffered 
  from 
  the 
  

   draining 
  of 
  their 
  feeding 
  and 
  breeding 
  grounds, 
  and 
  by 
  killing 
  for 
  sport 
  and 
  

   the 
  market. 
  Tens 
  of 
  millions 
  of 
  birds 
  were 
  sacrificed 
  annually. 
  Dr. 
  

   Oberholser 
  described 
  and 
  illustrated 
  with 
  lantern 
  slides 
  many 
  of 
  the 
  lakes 
  of 
  

   the 
  region 
  used 
  as 
  breeding 
  grounds 
  of 
  water 
  fowl, 
  and 
  nests 
  and 
  birds 
  were 
  

   shown 
  of 
  several 
  of 
  the 
  species. 
  The 
  paper 
  was 
  discussed 
  by 
  Dr. 
  vShufeldt.
