  and 
  the 
  latter 
  were 
  very 
  pretty, 
  when 
  covered 
  with 
  

   white 
  bracts, 
  as 
  in 
  June, 
  or 
  when 
  covered 
  with 
  scarlet 
  berries, 
  as 
  in 
  

   August. 
  

  

  Propagating 
  ponds. 
  Since 
  the 
  three 
  ponds 
  reserved 
  by 
  the 
  state 
  

   for 
  fish-propagating 
  purposes 
  were 
  the 
  scene 
  of 
  our 
  principal 
  field 
  

   studies, 
  a 
  few 
  words 
  concerning 
  their 
  character 
  may 
  best 
  be 
  said 
  here. 
  

  

  Bo7ie 
  pond 
  is 
  quite 
  small, 
  as 
  our 
  map 
  will 
  show, 
  is 
  hidden 
  in 
  deep 
  

   woods, 
  and 
  is 
  accessible 
  only 
  by 
  a 
  " 
  carry 
  " 
  from 
  Little 
  Green. 
  It 
  has 
  

   gently 
  sloping 
  banks 
  round 
  about, 
  there 
  being 
  no 
  outlet, 
  the 
  hemlocks 
  of 
  

   the 
  woods 
  come 
  down 
  near 
  to 
  the 
  shore, 
  and 
  there 
  is 
  not 
  the 
  usual 
  fringe 
  

   of 
  tamaracks 
  outside 
  the 
  sphagnum 
  moss 
  which 
  thinly 
  fringes 
  its 
  banks, 
  

   but 
  the 
  sphagnum 
  is 
  grown 
  full 
  of 
  lambkill 
  and 
  other 
  small 
  heaths. 
  

   The 
  sphagnum 
  ends 
  in 
  shallow 
  water 
  and 
  is 
  followed 
  by 
  a 
  zone 
  of 
  

   sedge, 
  Dulichium. 
  arundinaceum 
  (L.) 
  Britton, 
  and 
  manna 
  

   grass, 
  Panicularia 
  sp.? 
  In 
  the 
  deeper 
  water, 
  but 
  not 
  forming 
  a 
  

   continuous 
  zone 
  except 
  for 
  short 
  distances, 
  are 
  stretches 
  of 
  yellow 
  water 
  

   lilies, 
  Nymphaea 
  advena 
  Soland., 
  and 
  a 
  species 
  of 
  bur 
  reed 
  with 
  

   very 
  long 
  stem 
  and 
  leaves, 
  the 
  latter 
  not 
  rising 
  from 
  the 
  surface, 
  but 
  

   lying 
  flat 
  and 
  directed 
  generally 
  off 
  shore, 
  Sp 
  arg 
  an 
  ium 
  simplex 
  

   angusti 
  folium 
  (Mx.) 
  Englm.? 
  In 
  the 
  more 
  open 
  places 
  along 
  

   shore 
  a 
  species 
  of 
  pipevvort, 
  Eriocaulon 
  septangulare 
  Wither., 
  

   was 
  observed 
  growing 
  abundantly, 
  and 
  extending 
  out 
  into 
  deeper 
  water 
  

   by 
  a 
  succession 
  of 
  stolons, 
  which 
  rooted 
  readily 
  to 
  the 
  white 
  sand 
  of 
  the 
  

   bottom. 
  Among 
  these 
  lay 
  loosely 
  small 
  masses 
  of 
  moss 
  and 
  filamentous 
  

   algae. 
  In 
  such 
  places 
  the 
  sieve 
  net 
  brought 
  up 
  from 
  the 
  bottom, 
  

   where 
  they 
  were 
  beyond 
  view 
  and 
  almost 
  beyond 
  reach 
  of 
  the 
  net, 
  

   besides 
  the 
  pipewort, 
  moss 
  and 
  algae, 
  great 
  quantities 
  of 
  empty 
  caddis 
  

   fly 
  cases 
  of 
  the 
  species 
  described 
  in 
  the 
  following 
  account 
  of 
  that 
  group 
  

   by 
  Mr 
  Betten 
  as 
  no. 
  2, 
  p. 
  572, 
  and 
  also 
  the 
  loose, 
  flocculent 
  cases 
  of 
  

   blood 
  worms 
  (larvae 
  of 
  gnats, 
  Chironomidae) 
  ; 
  but 
  the 
  larvae 
  of 
  the 
  

   gnats 
  themselves 
  were 
  not 
  found 
  except 
  in 
  the 
  stomachs 
  of 
  the 
  brook 
  

   trout 
  which 
  lived 
  in 
  this 
  pond, 
  and 
  in 
  these 
  they 
  were 
  abundant. 
  The 
  

   burrowing 
  nymphs 
  of 
  dragon 
  flies, 
  Gomphus, 
  were 
  also 
  common 
  

   here, 
  where 
  they 
  burrow 
  along 
  under 
  the 
  thin 
  layer 
  of 
  silt 
  that 
  covers 
  the 
  

   sand. 
  They 
  seemed 
  to 
  escape 
  the 
  trout. 
  Among 
  the 
  sedges 
  and 
  grasses 
  

   nearer 
  shore 
  other 
  dragon 
  fly 
  nymphs 
  and 
  caddis 
  fly 
  larvae 
  were 
  also 
  

   abundant. 
  

  

  This 
  pond 
  was 
  farther 
  from 
  headquarters 
  than 
  were 
  any 
  of 
  the 
  other 
  

   situations 
  in 
  which 
  we 
  planned 
  field 
  studies. 
  We 
  did 
  not 
  visit 
  it 
  till
