  sight 
  too 
  scanty 
  or 
  too 
  forbidding, 
  even 
  to 
  support 
  life. 
  

   There 
  are 
  immense 
  districts 
  in 
  parts 
  of 
  the 
  Australian 
  conti- 
  

   nent 
  where 
  nocks 
  are 
  kept 
  on 
  plants 
  so 
  dry 
  and 
  desert-like 
  that 
  

   an 
  inexperienced 
  person 
  would 
  pass 
  them 
  by 
  as 
  not 
  fit 
  for 
  

   his 
  sheep, 
  and 
  yet, 
  as 
  Mr. 
  Samuel 
  Dixon 
  30 
  has 
  well 
  shown, 
  these 
  

   plants 
  are 
  of 
  high 
  nutritive 
  value 
  and 
  are 
  attractive 
  to 
  flocks. 
  

  

  Relegating 
  to 
  the 
  notes 
  to 
  be 
  published 
  with 
  this 
  address 
  

   brief 
  descriptions 
  of 
  a 
  few 
  of 
  the 
  fodder 
  plants 
  suggested 
  for 
  

   use 
  in 
  dry 
  districts, 
  I 
  shall 
  now 
  mention 
  the 
  salt-bushes 
  of 
  

   various 
  sorts, 
  and 
  the 
  allied 
  desert 
  plants 
  of 
  Australia 
  as 
  worth 
  

   a 
  careful 
  trial 
  on 
  some 
  of 
  our 
  very 
  dry 
  regions 
  in 
  the 
  farthest 
  

   west. 
  There 
  are 
  numerous 
  other 
  excellent 
  fodder 
  plants 
  

   adapted 
  to 
  dry 
  but 
  not 
  parched 
  areas 
  which 
  can 
  be 
  brought 
  in 
  

   from 
  the 
  corresponding 
  districts 
  of 
  the 
  southern 
  hemisphere 
  

   and 
  from 
  the 
  East. 
  

  

  At 
  an 
  earlier 
  stage 
  of 
  this 
  address, 
  I 
  have 
  had 
  occasion 
  to 
  

   refer 
  to 
  Baron 
  von 
  Mueller, 
  whose 
  efforts 
  looking 
  towards 
  the 
  

   introduction 
  of 
  useful 
  plants 
  into 
  Australasia 
  have 
  been 
  aided 
  

   largely 
  by 
  his 
  convenient 
  treatise 
  on 
  economic 
  plants. 
  It 
  may 
  

   be 
  said 
  in 
  connection 
  with 
  the 
  fodder 
  plants, 
  especially, 
  that 
  

   much 
  which 
  the 
  Baron 
  has 
  written 
  can 
  be 
  applied 
  mutatis 
  

   mutandis 
  to 
  parts 
  of 
  our 
  own 
  country. 
  

  

  The 
  important 
  subject 
  of 
  introducing 
  fodder 
  plants 
  has 
  been 
  

   purposely 
  reserved 
  to 
  the 
  last 
  because 
  it 
  permits 
  us 
  to 
  examine 
  

   a 
  practical 
  point 
  of 
  great 
  interest. 
  This 
  is 
  the 
  caution 
  which 
  

   it 
  is 
  thought 
  necessary 
  to 
  exercise 
  when 
  a 
  species 
  is 
  transferred 
  

   by 
  our 
  own 
  choice 
  from 
  one 
  country 
  to 
  another. 
  I 
  say, 
  by 
  

   our 
  choice, 
  for 
  whether 
  we 
  wish 
  it 
  or 
  not 
  certain 
  plants 
  will 
  

   introduce 
  themselves. 
  In 
  these 
  days 
  of 
  frequent 
  and 
  intimate 
  

   intercommunication 
  between 
  different 
  countries, 
  the 
  exclusion 
  

   of 
  foreign 
  plants 
  is 
  simply 
  impossible. 
  Our 
  common 
  weeds 
  

   are 
  striking 
  illustrations 
  of 
  the 
  readiness 
  with 
  which 
  plants 
  of 
  

   one 
  country 
  make 
  for 
  themselves 
  a 
  home 
  in 
  another. 
  31 
  All 
  but 
  

   two 
  of 
  the 
  prominent 
  weeds 
  of 
  the 
  eastern 
  States 
  are 
  foreign 
  

   intruders. 
  

  

  There 
  are 
  all 
  grades 
  of 
  persistence 
  in 
  these 
  immigrants. 
  

   Near 
  the 
  ballast 
  grounds 
  of 
  every 
  harbor, 
  or 
  the 
  fields 
  close 
  by 
  

   woolen 
  and 
  paper 
  mills 
  where 
  foreign 
  stock 
  is 
  used, 
  you 
  will 
  

   observe 
  many 
  foreign 
  plants 
  which 
  have 
  been 
  introduced 
  by 
  

   seed. 
  For 
  many 
  of 
  these 
  you 
  will 
  search 
  in 
  vain 
  a 
  second 
  

   year. 
  A 
  few 
  others 
  persist 
  for 
  a 
  year 
  or 
  two 
  longer, 
  but 
  with 
  

   uncertain 
  tenure 
  of 
  the 
  land 
  which 
  they 
  have 
  invaded 
  : 
  others 
  

   still 
  have 
  come 
  to 
  stay. 
  But 
  happily 
  some 
  of 
  the 
  intruders 
  

   which 
  seem 
  at 
  first 
  to 
  gain 
  a 
  firm 
  foot-hold, 
  lose 
  their 
  ground 
  

   after 
  a 
  while. 
  We 
  have 
  a 
  conspicuous 
  example 
  of 
  this 
  in 
  a 
  

   hawkweed, 
  which 
  was 
  very 
  threatening 
  in 
  New 
  England 
  two 
  

   years 
  ago, 
  but 
  is 
  now 
  relaxing 
  its 
  hold.
