  The 
  final 
  pliasc 
  ol 
  the 
  campaign 
  was 
  to 
  consist 
  of 
  a 
  prompt 
  reply 
  

   to 
  all 
  demands 
  for 
  aid, 
  and 
  a 
  personal 
  demonstration 
  of 
  the 
  methods 
  

   which 
  had 
  been 
  advised. 
  

  

  The 
  Revenue 
  Authorities 
  were 
  asked 
  to 
  helj) 
  ; 
  the 
  Educational 
  Depart- 
  

   ment 
  was 
  provided 
  with 
  lantern 
  slides 
  and 
  a 
  short 
  account 
  of 
  the 
  pest 
  so 
  

   that 
  lectures 
  could 
  be 
  given 
  in 
  schools. 
  School-masters 
  were 
  to 
  be 
  

   instructed 
  to 
  get 
  into 
  touch 
  with 
  the 
  officer 
  lecturing 
  in 
  the 
  taluq 
  in 
  which 
  

   his 
  school 
  was 
  situated 
  so 
  that 
  should 
  the 
  pest 
  appear 
  school-children 
  

   could 
  be 
  shown 
  it 
  in 
  the 
  fields 
  and 
  the 
  opportunity 
  given 
  of 
  at 
  least 
  one 
  

   piece 
  of 
  nature 
  study. 
  Lastly 
  the 
  co-operative 
  societies 
  which 
  were 
  very 
  

   strong 
  in 
  one 
  taluq^ 
  were 
  to 
  be 
  asked 
  to 
  help 
  to 
  gather 
  raiyats 
  together 
  

   and 
  to 
  read 
  leaflets 
  and 
  posters. 
  

  

  The 
  control 
  methods 
  which 
  were 
  advocated 
  and 
  which 
  have 
  given 
  

   satisfactory 
  results 
  in 
  the 
  past 
  were 
  as 
  follows 
  : 
  — 
  

  

  (1) 
  On 
  the 
  appearance 
  of 
  the 
  caterpillar 
  the 
  first 
  thing 
  to 
  do 
  is 
  to 
  

   isolate 
  the 
  attacked 
  area 
  by 
  digging 
  steep-sided 
  trenches 
  around 
  it. 
  

   The 
  caterpillars 
  as 
  they 
  migrate 
  fall 
  into 
  these 
  trenches 
  and 
  are 
  unable 
  

   to 
  climb 
  out. 
  They 
  can 
  then 
  be 
  easily 
  crushed 
  and 
  killed. 
  In 
  the 
  mean- 
  

   time 
  the 
  caterpillars 
  in 
  the 
  attacked 
  areas 
  can 
  be 
  collected 
  in 
  winnowing 
  

   fans 
  and 
  bags 
  and 
  destroyed. 
  

  

  (2) 
  Where 
  water 
  is 
  available 
  the 
  attacked 
  areas 
  can 
  be 
  flooded 
  and 
  

   the 
  caterpillars 
  driven 
  to 
  the 
  tops 
  of 
  the 
  blades 
  of 
  paddy 
  from 
  which 
  

   they 
  can 
  be 
  either 
  knocked 
  ofi 
  and 
  drowned 
  by 
  dragging 
  a 
  rope 
  or 
  bamboo 
  

   across, 
  or 
  they 
  can 
  be 
  collected 
  by 
  hand. 
  In 
  this 
  case 
  also 
  they 
  are 
  

   much 
  exposed 
  to 
  the 
  attacks 
  of 
  birds, 
  who 
  are 
  always 
  of 
  great 
  assistance. 
  

  

  If 
  the 
  rope 
  method 
  is 
  used, 
  water 
  should 
  be 
  drained 
  off 
  after 
  the 
  

   caterpillars 
  have 
  been 
  knocked 
  from 
  the 
  plants 
  as, 
  if 
  fairly 
  old, 
  they 
  can 
  

   climb 
  up 
  the 
  stems 
  again. 
  Young 
  caterpillars 
  are 
  easily 
  drowned. 
  

  

  (3) 
  After 
  an 
  attack 
  by 
  Spodopteray 
  bands 
  should 
  be 
  scraped 
  and 
  pupse 
  

   exposed 
  or 
  destroyed. 
  

  

  (4) 
  It 
  is 
  the 
  custom 
  in 
  some 
  parts 
  of 
  Malabar 
  to 
  scatter 
  rice 
  on 
  the 
  

   bands 
  when 
  Spodoptera 
  has 
  appeared, 
  in 
  order 
  to 
  attract 
  the 
  birds. 
  

  

  (5) 
  Before 
  there 
  is 
  any 
  water 
  in 
  the 
  fields 
  a 
  close 
  watch 
  is 
  to 
  be 
  kept 
  

   on 
  broad-cast 
  paddy 
  and 
  on 
  seed-beds. 
  

  

  (6) 
  Provision 
  of 
  perches 
  for 
  birds 
  in 
  the 
  fields. 
  

  

  (7) 
  Isolation 
  of 
  seed 
  beds 
  by 
  trenches. 
  

  

  This 
  was 
  the 
  ideal. 
  How 
  far 
  the 
  realization 
  fell 
  short 
  of 
  it 
  will 
  now 
  

   be 
  shown. 
  

  

  With 
  the 
  exception 
  of 
  one 
  tahiq 
  (Calicut) 
  all 
  lectures
