  low 
  hummock 
  of 
  land 
  covered 
  with 
  cat-tails. 
  Behind 
  this 
  hummock 
  was 
  

   a 
  shallow 
  stretch 
  of 
  water 
  in 
  which 
  we 
  did 
  some 
  most 
  profitable 
  collect- 
  

   ing. 
  The 
  bottom 
  here 
  had 
  once 
  been 
  dry 
  land, 
  and 
  was 
  covered 
  mainly 
  

   with 
  fragments 
  of 
  bark 
  and 
  twigs, 
  but 
  it 
  was 
  the 
  home 
  of 
  numerous 
  caddis 
  

   ily 
  larvae, 
  particularly 
  those 
  with 
  cases 
  of 
  stick 
  chimney, 
  or 
  cobhouse 
  

   type, 
  and 
  of 
  the 
  nymphs 
  of 
  the 
  fine 
  May 
  fly, 
  Siphlurus 
  alter- 
  

   n

  Say. 
  The 
  west 
  shore 
  of 
  the 
  outlet 
  was 
  more 
  accessible 
  ; 
  and, 
  

   though 
  collecting 
  along 
  it 
  was 
  not 
  easy 
  because 
  of 
  the 
  abundance 
  of 
  

   brushwood 
  to 
  entangle 
  a 
  net, 
  it 
  yielded 
  a 
  great 
  deal 
  of 
  most 
  valuable 
  

   material, 
  particularly 
  dragon 
  fly 
  nymphs. 
  My 
  only 
  specimens 
  of 
  the 
  

   nymphs 
  of 
  the 
  two 
  beautiful 
  species,

   and 
  Leucorhinia 
  glacialis 
  Hagen, 
  were 
  obtained 
  along 
  this 
  

   shore 
  in 
  a 
  sheltered 
  place. 
  

  

  Through 
  the 
  outlet 
  there 
  flows 
  an 
  imperceptible 
  current, 
  which 
  may 
  be 
  

   responsible 
  for 
  the 
  presence 
  of 
  two 
  interesting 
  plants 
  there 
  which 
  were 
  

   not 
  observed 
  elsewhere, 
  the 
  water 
  shield, 
  Brasenia 
  peltata 
  

   Pursh, 
  and 
  shining 
  river 
  weed, 
  Potamogeton 
  lucens 
  Linn. 
  

   Of 
  the 
  latter 
  there 
  was 
  a 
  bed 
  directly 
  in 
  the 
  channel, 
  and, 
  passing 
  

   over 
  in 
  a 
  boat 
  it 
  was 
  delightful 
  to 
  look 
  down 
  into 
  the 
  depths 
  of 
  the 
  

   clear 
  water, 
  at 
  the 
  long 
  graceful 
  sprays 
  of 
  shining 
  lutescent 
  leaves. 
  A 
  

   species 
  of 
  bladder 
  wort, 
  Utricularia, 
  was 
  not 
  uncommon 
  in 
  the 
  

   shallow 
  water 
  behind 
  the 
  cat-tail 
  hummock, 
  and 
  two 
  species 
  of 
  shinleaf 
  

   grew 
  there 
  at 
  the 
  shore, 
  Pyrola 
  secunda

  Of 
  the 
  numerous 
  small 
  ponds 
  in 
  the 
  vicinity 
  of 
  Saranac 
  

   Inn, 
  hidden 
  in 
  the 
  woods 
  and 
  fringed 
  with 
  a 
  typical 
  floating 
  border 
  of 
  

   bog 
  moss, 
  we 
  collected 
  extensively 
  at 
  but 
  one 
  — 
  the 
  one 
  a 
  quarter 
  of 
  a 
  

   mile 
  southwest 
  of 
  the 
  station 
  and 
  south 
  of 
  the 
  track 
  — 
  and 
  visited 
  but 
  one 
  

   other, 
  about 
  as 
  far 
  east 
  of 
  the 
  station 
  and 
  north 
  of 
  the 
  track. 
  Of 
  the 
  

   former 
  only 
  I 
  will 
  speak 
  here; 
  the 
  other 
  was 
  very 
  similar. 
  

  

  This 
  little 
  pond 
  (pi. 
  7) 
  was 
  a 
  woodland 
  gem. 
  The 
  picture 
  of 
  it 
  presented 
  

   herewith 
  gives 
  but 
  a 
  poor 
  idea 
  of 
  it; 
  for 
  the 
  fine 
  coloration 
  of 
  fringing 
  

   vegetation, 
  of 
  forest 
  background, 
  and 
  of 
  water 
  and 
  sky 
  are 
  necessarily 
  

   absent 
  from 
  the 
  picture. 
  It 
  was 
  a 
  peculiar 
  place 
  to 
  collect 
  in, 
  being 
  dif- 
  

   ficult 
  of 
  access, 
  and 
  very 
  difficult 
  to 
  collect 
  in 
  when 
  reached 
  ; 
  but 
  it 
  was 
  

   conveniently 
  near 
  at 
  hand, 
  and 
  was 
  peculiarly 
  attractive 
  on 
  account 
  of 
  

   the 
  many 
  beautiful 
  and 
  interesting 
  plants 
  and 
  insects 
  found 
  there. 
  Its 
  

   vegetation 
  (pi. 
  8) 
  showed 
  a 
  beautiful 
  zonal 
  distribution.
