abundantly  than  here.  Although  surrounded  by  water  and  thereby  doubtless 
provided  with  a  damp  atmosphere,  yet  both  these  islands  cannot  boast  of  any 
ferns,  if  the  few  specimens  of  Polypodium  vulgare,  Lin.,  seen  on  the  highest 
rocky  part  of  Kelly's  Island,  are  excepted.  On  the  low  sandy  parts  of  the 
islands  the  botanist  meets  many  of  the  plants  which  usually  occur  also  on  the 
lakeshore  and  in  the  adjacent  swamps. 
After  having  at  this  point  finished  his  expedition  to  the  islands,  he  returns 
to  the  fields  of  his  home  ;  the  steamer  carries  him  over  the  greenish  water  of 
the  lake  in  several  hours'  time  and  after  a  short  rest  (sometimes  very  necessary 
on  account  of  the  rough  treatment  of  him  by  the  waves),  and  after  having 
well  arranged  all  the  specimens  collected,  he  is  prepared  to  explore  the  lake- 
shore  and  the  swamps  near  it.  The  sandy  (or  clayey)  shore  of  Lake  Erie, 
over  which,  particularly  in  warmer  weather,  there  often  hovers  an  atmosphere 
more  or  less  saturated  with  water,  provides  an  habitation  to  many  rare  plants  ; 
for  instance,  to  Cakile  americana,  Nutt.,  Polanisia  graveolens,  Raf.,  Euphor- 
bia polygonifolia,  Lin.,  Strophostyles  angulosa,  Ell.,  Triodia  purpurea,  Hack., 
Cenchrus  tribuloides,  Lin.,  Sporobolus  cryptandrus,  Gray,  as  apparently  also 
to  Bidens  bipinnata,  Li?i.,  which  was  seen  in  but  one  place  on  a  stony  slope, 
and  to  Gentiana  crinita,  Froel.,  Calamagrostis  longifolia,  Hook.,  Potentilla 
anserina,  Lin.  The  swamp  situated  on  and  near  the  shore,  mainly  that  of  the 
Cuyahoga  valley  on  Whisky  Island,  the  gradual  disappearance  of  which  the 
botanist  regrets  very  much,  furnishes  him  (or  did  furnish  within  the  last  years) 
with  Lysimachia  thyrsifiora,  Lin.,  the  splendid  Hibiscus  Moscheutos,  Lin.Y 
Eclipta  alba,  Hassk.,  Phragmites  communis,  Trin.,  Scirpus  polyphyllus,  Vahl, 
Proserpinaca  palustris,  Lin.,  and  Decodon  verticillatus,  Ell.,  a  shrub  frequent 
in  many  swamps  throughout  the  lake  region.  The  presence  of  Pedicularis 
lanceolata,  Michx.,  and  of  Juncus  Gerardi,  Loisel.  (2  tufts  only),  may  be  men- 
tioned here.  In  parts  further  west  (in  Ottawa  County)  a  great  bog  on  L.  S. 
R.  R.  near  Gypsum  awakened  the  botanist's  interest  by  the  presence  there  of 
Solidago  Riddelii,  Frank,  Hypericum  gymnanthum,  Engelm.  and  Gray,  Pre- 
nanthesracemosa,  Michx.,  and  of  the  Lythrum  of  South  Bass  Island,  alatum, 
Pursh.  The  fields  between  Gypsum  and  Port  Clinton,  although  not  of 
a  swampy  nature,  but  nevertheless  under  the  influence  of  moisture,  being 
bounded  on  the  south  by  Sandusky  Bay  and  on  the  north  by  Lake  Erie,  should 
also  be  considered  here.  Within  half  an  hour's  time  the  botanist  could  collect 
here  :  Euphorbia  dentata,  Michx.,  Silphium  terebinthinaceum,  Lin.,  Spartina 
cynosuroides,  Willd.,  Lophanthus  nepetoides,  Benth.,  and  Rudbeckia  triloba, 
Lin.,  with  its  yellow  rays  and  dark  purple  disks.  He  has  now  reached 
the  lakeshore  ;  in  sandy  places  he  finds  Panicum  virgatum,  Lin.  Further 
east,  however,  a  big  swamp  is  situated,  which  the  botanist  can  only  partly 
penetrate.  Millions  of  the  common  Scirpus  pungens,  Vahl,  grow  there,  but 
also  up  to  5  feet  high  the  Boltonia  asteroides,  L'  Her.,  with  innumerable 
flowers.  Tired  as  he  is  by  his  attempt  to  walk  through  the  dense  vegetation 
there,  he  leaves  this  place,  turning  his  steps  southward  to  the  rich  woods, 
where  he  meets  Polymnia  canadensis,  Lin.,  and  the  interesting  Xanthoxylum 
americanum,  Mill.;  Sicyos  angulatus,  Lin.,  covers  these  bushes  and  shrubs  up 
to  20  feet  high.  Further  northeast  the  woods  lose  their  richness  of  soil,  dis~ 
appear  then  almost  entirely,  sand  takes  their  place,  the  proper  material  for 
the  growth  of  Gerardia  purpurea,  Lin,,  and  Triodia  cuprea,  Jacq.
