  I 
  think 
  it 
  probable 
  that 
  the 
  infestation 
  of 
  the 
  greenhouses 
  has 
  come 
  

   from 
  the 
  piles 
  of 
  manure 
  brought 
  into 
  them, 
  as 
  milHpeds 
  are 
  known 
  

   frequently 
  to 
  abound 
  in 
  manure, 
  and 
  are 
  believed 
  to 
  breed 
  in 
  it. 
  If 
  on 
  

   examination 
  they 
  prove 
  to 
  be 
  present 
  in 
  large 
  numbers 
  in 
  the 
  manure, 
  

   some 
  efficient 
  measure 
  that 
  may 
  suggest 
  itself 
  should 
  be 
  taken 
  for 
  destroy- 
  

   ing 
  them 
  in 
  it, 
  and 
  the 
  manure 
  should 
  be 
  removed 
  to 
  some 
  distance 
  

   from 
  the 
  houses. 
  

  

  The 
  following 
  thorough 
  measures 
  proved, 
  as 
  might 
  be 
  expected, 
  an 
  

   effectual 
  means 
  of 
  ridding 
  the 
  greenhouses 
  of 
  the 
  pests.

   and

  In 
  the 
  spring 
  we 
  removed 
  all 
  plants 
  from 
  the 
  greenhouses, 
  also 
  all 
  

   wooden 
  benches, 
  and 
  everything 
  but 
  the 
  bare 
  brick 
  walls 
  and 
  the 
  glass 
  

   roofs. 
  The 
  floors 
  had 
  been 
  concreted. 
  We 
  burned 
  sulphur 
  in 
  liberal 
  quanti- 
  

   ties 
  three 
  times 
  a 
  week 
  for 
  several 
  weeks. 
  Then 
  we 
  dusted 
  all 
  interiors 
  

   thoroughly 
  with 
  hellebore, 
  and 
  in 
  the 
  fall, 
  just 
  before 
  replacing 
  plants 
  

   in 
  the 
  houses, 
  we 
  coated 
  all 
  interiors 
  with 
  whitewash. 
  Since 
  then 
  we 
  

   have 
  not 
  found 
  a 
  single 
  one 
  of 
  these 
  unpleasant 
  pests.

  The 
  above-mentioned 
  treatment 
  should 
  exterminate 
  almost 
  any 
  pest 
  

   to 
  be 
  found 
  in 
  a 
  greenhouse. 
  Such 
  a 
  fumigation 
  might 
  well 
  be 
  given 
  

   greenhouses 
  that 
  are 
  empty 
  or 
  nearly 
  so 
  during 
  the 
  summer 
  as 
  a 
  pre- 
  

   ventive 
  to 
  the 
  undue 
  abundance 
  of 
  any 
  injurious 
  animal 
  or 
  plant 
  form 
  

   the 
  coming 
  season. 
  Then 
  if 
  a 
  little 
  care 
  be 
  exercised 
  when 
  the 
  house 
  is 
  

   filled 
  in 
  the 
  autumn, 
  not 
  to 
  introduce 
  any 
  pests, 
  very 
  little 
  trouble 
  

   should 
  be 
  experienced 
  in 
  keeping 
  the 
  plants 
  in 
  a 
  healthy 
  growing 
  

   condition.
