  contend 
  with. 
  This 
  may 
  be 
  due 
  to 
  the 
  poorer 
  soil, 
  and 
  a 
  

   plant 
  harmless 
  in 
  its 
  native 
  place 
  becomes 
  a 
  noxious 
  weed 
  

   when 
  supplied 
  with 
  abundant 
  food 
  in 
  the 
  farm 
  and 
  garden. 
  

   From 
  the 
  conditions 
  of 
  growth, 
  accompanied 
  by 
  Panicum 
  

   virgatum 
  and 
  the 
  willows 
  and 
  cornel 
  bushes 
  characteristic 
  of 
  

   the 
  shore, 
  and 
  cut 
  off 
  by 
  a 
  wide 
  extent 
  of 
  swampy 
  land 
  and 
  

   woods 
  from 
  any 
  cultivated 
  fields 
  where 
  it 
  might 
  be 
  growing, 
  

   I 
  consider 
  it 
  indigenous 
  here. 
  It 
  was 
  found 
  once 
  before 
  under 
  

   analogous 
  conditions 
  of 
  growth 
  upon 
  sand 
  hills 
  in 
  the 
  woods 
  

   and 
  barrens 
  east 
  of 
  Petoske}^ 
  and 
  at 
  a 
  distance 
  from 
  farms, 
  

   and 
  the 
  conclusion 
  was 
  plain 
  that 
  it 
  was 
  a 
  native 
  grass. 
  It 
  

   was 
  accompanied 
  b}' 
  A. 
  dasystachywn 
  Vasey, 
  regarded 
  as 
  in- 
  

   digenous 
  along 
  the 
  great 
  lakes. 
  The 
  evidence 
  of 
  nativity 
  in 
  

   both 
  is 
  equally 
  good, 
  and 
  the 
  conditions 
  of 
  growth 
  can 
  not 
  

   be 
  disconnected 
  so 
  as 
  to 
  give 
  a 
  different 
  origin 
  to 
  the 
  two. 
  

   The 
  plants 
  found 
  at 
  Marquette 
  were 
  mostly 
  taller 
  than 
  those 
  

   m 
  cultivated 
  ground, 
  and 
  grew 
  somewhat 
  isolated, 
  generally 
  

   not 
  more 
  than 
  a 
  single 
  stalk 
  from 
  the 
  same 
  root. 
  

  

  ^ 
  Another 
  native 
  grass, 
  Festuca 
  ovina, 
  was 
  collected 
  in 
  this 
  

   vicmity. 
  It 
  was 
  found 
  on 
  a 
  mass 
  of 
  rock, 
  called 
  Picnic 
  Isl- 
  

   and, 
  much 
  frequented 
  by 
  the 
  children 
  of 
  the 
  city 
  for 
  their 
  

   pastimes. 
  It
