﻿Harper: 
  A 
  week

  eastern 
  Texas

  Texas, 
  XXIV"* 
  deals 
  with 
  Cherokee 
  County, 
  but 
  mentions 
  only 
  

   about 
  a 
  dozen 
  species 
  of 
  plants, 
  and 
  several 
  of 
  these 
  are 
  introduced. 
  

   I 
  crossed 
  the 
  region 
  in 
  going 
  from 
  Houston 
  to 
  Shreveport, 
  and 
  the 
  

   country 
  between 
  Lufkin 
  and 
  the 
  Sabine 
  River 
  (72 
  miles) 
  may 
  be 
  

   considered 
  typical. 
  The 
  following 
  spem 
  to 
  be 
  the 
  commonest 
  

   woody 
  plants 
  along 
  the 
  route 
  just 
  indicated.

  Rhus

  As 
  in 
  many 
  other 
  wooded 
  regions, 
  the 
  herbs 
  recognizable 
  from 
  

   a 
  train 
  in 
  summer 
  are 
  mostly 
  weeds. 
  Helenium 
  tenuifoUnm 
  seems 
  

  

  pitatus 
  

  

  are 
  considerably 
  scarcer.

  The 
  long-leaf 
  pine 
  regio«.— 
  This 
  lies 
  south 
  of 
  the 
  red 
  hills, 
  but 
  

   not 
  necessarily 
  immediately 
  adjacent 
  thereto. 
  (Not 
  having 
  

   passed 
  directly 
  from 
  o;ie 
  to 
  the 
  other 
  in 
  Texas, 
  I 
  cannot 
  say 
  whether 
  

   the 
  transition 
  is 
  abrupt 
  or 
  there 
  is 
  some 
  other 
  kind 
  of 
  country 
  

   between, 
  as 
  the 
  geological 
  maps 
  suggest.) 
  Its 
  western 
  1 
  

   to 
  be 
  in 
  Polk 
  County, 
  though 
  very 
  likely 
  there 
  are 
  scattered 
  

   long-leaf 
  pines 
  outside 
  the 
  area 
  indicated 
  on 
  the 
  map. 
  It 
  does 
  

   not 
  correspond 
  with 
  any 
  one 
  formation 
  on 
  the 
  latest 
  geological 
  

   maps, 
  but 
  its 
  strata 
  are 
  approximately 
  contemporaneous 
  with 
  the 
  

   Altahama 
  Grit 
  of 
  Georgia 
  and 
  probably 
  not 
  older 
  than 
  Miocene. 
  

   The 
  topography 
  of 
  the 
  parts 
  I 
  saw 
  is 
  gently 
  undulating, 
  but 
  it 
  is 
  said 
  

   to 
  be 
  more 
  hilly 
  farther 
  north. 
  Running 
  water 
  is 
  rather 
  scarce, 
  

   probably 
  on 
  account 
  of 
  the 
  soil, 
  which 
  instead 
  of 
  being 
  decidedly 
  

   sandy 
  and 
  holding 
  water 
  long 
  after 
  a 
  rain, 
  as 
  in 
  the 
  Atlantic 
  pme
