  I 
  should 
  be 
  inclined 
  to 
  think 
  that 
  continuo^^s 
  corn-growing 
  in 
  Great 
  

   Britain 
  could 
  hardly 
  come 
  into 
  competition 
  with 
  a 
  rotation 
  of 
  crops, 
  for 
  one 
  

   reason 
  in 
  particular, 
  — 
  viz., 
  the 
  want 
  of 
  provision 
  for 
  destruction 
  of 
  weeds. 
  

   This 
  is 
  a 
  difficulty 
  which 
  Avould 
  also 
  occur 
  in 
  New 
  Zealand, 
  where, 
  from 
  the 
  

   moisture 
  of 
  the 
  climate, 
  weeds 
  are 
  very 
  difficult 
  to 
  be 
  kept 
  under. 
  If 
  a 
  

   good 
  payable 
  system 
  of 
  rotation 
  for 
  this 
  colony 
  could 
  be 
  hit 
  upon, 
  I 
  am 
  

   inclined 
  to 
  think 
  it 
  would 
  beat 
  the 
  continuous 
  corn-growing 
  system. 
  If, 
  

   however, 
  farmers 
  will 
  continue 
  to 
  work 
  their 
  land 
  on 
  the 
  latter 
  plan, 
  I 
  will 
  

   again 
  reiterate 
  that 
  they 
  cannot 
  continue 
  to 
  do 
  so 
  for 
  many 
  years 
  without 
  

   giving 
  and 
  keeping 
  up 
  a 
  sujpply 
  of 
  phosphate 
  of 
  lime, 
  of 
  potash, 
  and 
  of 
  

   nitrogen. 
  

  

  I 
  have 
  seen 
  it 
  stated, 
  on 
  excellent 
  authority, 
  that 
  pastures 
  which 
  are 
  

   deficient 
  in 
  phosphate 
  of 
  lime 
  in 
  the 
  soil 
  ought 
  never 
  to 
  be 
  used 
  for 
  breed- 
  

   ing 
  sheep 
  ; 
  for 
  the 
  lambs 
  031 
  such 
  pastures 
  scour, 
  get 
  pot-bellied, 
  are 
  deficient 
  

   in 
  size, 
  and 
  many 
  of 
  them 
  die. 
  This 
  seems 
  according 
  to 
  reason, 
  for 
  if 
  there 
  

   is 
  an 
  insufficient 
  supply 
  of 
  mineral 
  to 
  form 
  the 
  bones, 
  the 
  animal 
  must 
  

   probably 
  also 
  suffer 
  in 
  other 
  ways. 
  Possibly, 
  when 
  the 
  sheep 
  has 
  attained 
  full 
  

   growth, 
  and 
  his 
  bones 
  are 
  fully 
  formed, 
  these 
  pastures 
  may 
  do 
  for 
  fattening 
  

   him 
  ; 
  or, 
  if 
  it 
  mil 
  pay, 
  the 
  land 
  may 
  be 
  treated 
  with 
  bone-dust, 
  but 
  it 
  would 
  

   be 
  absurd 
  to 
  suppose 
  that 
  this 
  could 
  be 
  done 
  with 
  profit 
  on 
  a 
  large 
  sheep- 
  

   run 
  and 
  with 
  stock 
  at 
  present 
  prices.
