The  investigation  of  this  region  was  carried  on  in  somewhat  the  fol-
lowing manner.  The  party,  consisting  of  Prof.  Russell,  a  camp  keeper
and  cook,*and  myself,  would  fix  upon  a  camping  place  from  which  the
country  around  would  be  worked  over  in  such  a  nmnner  as  the  require-
ments of  the  geological  work  demanded,  and,  while  this  was  being  done,
my  notes  and  studies  were  made.  The  roads  traversed  were  so  frequently
cut  through  standing  forests,  and  undrained  swamps,  that  it  was  not
necessary  to  go  far  from  them  to  get  satisfactory  opportunities  to  study
the  flora,  and  as  a  general  thing  much  of  the  material  gathered  was
picked  up  while  the  writer  was  accompanying  Prof.  Bussell  in  his  work,
and  it  was  rather  infrequently  the  case  that  it  was  necessary  to  delay
him  or  to  leave  him  to  take  time  for  independent  work,  although  this
was  at  times  done.
The  time  for  which  the  camp  was  located  in  one  place  was  varied
from  a  single  night  to  nearly  a  week,  this  depending  upon  the  character
of  the  <*ountry  and  the  quality  and  number  of  the  roads  which  could
be  profitably  reached  from  the  point  where  the  camp  was  placed.  In
all,  17  camps  were  made,  in  the  8  weeks  during  which  I  was  with  the
party,  and  some  of  these  camping  places  furnished  most  important  data
hearing  upon  the  problems  under  investigation,  and  the  others  furnished
most  interesting  problems  in  themselves,  some  of  which  still  remain  un-
solved.
