  It 
  will 
  he 
  seen 
  that 
  these 
  twenty-one 
  Illinois 
  colonies 
  oH 
  the 
  San 
  

   Jose 
  scale 
  are 
  all 
  in 
  orchards 
  or 
  small 
  fruit 
  plots, 
  and 
  none 
  of 
  them 
  in 
  

   nurseries. 
  In 
  every 
  case 
  thus 
  far 
  detected 
  the 
  original 
  importation 
  

   of 
  the 
  scale 
  was 
  made 
  directly 
  from 
  the 
  East 
  by 
  the 
  owner 
  of 
  the 
  

   orchard, 
  and 
  not 
  through 
  any 
  Illinois 
  nursery. 
  On 
  the 
  other 
  hand, 
  

   it 
  is 
  much 
  to 
  be 
  regretted 
  that 
  although 
  our 
  local 
  nurserymen 
  have 
  

   frequently 
  dealt 
  with 
  proprietors 
  of 
  eastern 
  nursery 
  grounds 
  which 
  

   are 
  now 
  known 
  to 
  have 
  been 
  at 
  one 
  time 
  infested, 
  my 
  inspectors 
  have 
  

   rarely 
  l)een 
  able 
  to 
  trace 
  any 
  stock 
  so 
  received 
  beyond 
  the 
  Illinois 
  

   nursery 
  through 
  which 
  it 
  has 
  passed 
  to 
  Illinois 
  customers; 
  it 
  is 
  con- 
  

   sequently 
  possible 
  that 
  some 
  cases 
  of 
  the 
  occurrence 
  of 
  the 
  scale 
  will 
  

   thus 
  escape 
  our 
  search. 
  

  

  DISINFECTION 
  OF 
  QUINCY 
  ORCHARD. 
  

  

  At 
  a 
  meeting 
  of 
  the 
  Executive 
  Board 
  of 
  the 
  State 
  Horticultural 
  

   Society 
  held 
  in 
  September. 
  18%, 
  the 
  facts 
  with 
  regard 
  to 
  this 
  or- 
  

   chard 
  were 
  reported 
  to 
  this 
  Board, 
  who 
  thereuijon 
  passed 
  a 
  resolution 
  

   requesting 
  the 
  State 
  Entomologist 
  to 
  undertake 
  the 
  extermination 
  of 
  

   the 
  scale 
  at 
  this 
  place, 
  and 
  making 
  an 
  appropriation 
  (not 
  to 
  exceed 
  

   $150) 
  from 
  the 
  funds 
  of 
  the 
  Horticultural 
  Society 
  for 
  the 
  expenses 
  

   of 
  this 
  procedure. 
  

  

  On 
  a 
  personal 
  visit 
  to 
  Mr. 
  Kiem's 
  place, 
  made 
  a 
  few 
  days 
  later, 
  I 
  

   came 
  to 
  an 
  agreement 
  with 
  him 
  that 
  he 
  should 
  permit 
  nothing 
  to 
  

   leave 
  his 
  premises 
  which 
  could 
  possibly 
  conve}'^ 
  the 
  scale 
  to 
  any 
  other 
  

   locality, 
  and 
  that 
  he 
  should 
  do 
  all 
  the 
  work 
  and 
  provide 
  all 
  the 
  assist- 
  

   ance 
  necessary 
  to 
  a 
  thorough 
  insecticide 
  treatment 
  of 
  everything 
  on 
  

   his 
  farm 
  which 
  could 
  harbor 
  the 
  scale, 
  on 
  condition 
  that 
  the 
  work 
  

   should 
  be 
  supervised 
  from 
  my 
  office 
  and 
  that 
  the 
  insecticide 
  should 
  

   be 
  furnished 
  him 
  at 
  our 
  expense. 
  As 
  the 
  female 
  scales 
  w(^re 
  still 
  giv- 
  

   ing 
  birth 
  to 
  young 
  at 
  this 
  time, 
  I 
  decided 
  to 
  postpone 
  operations 
  until 
  

   it 
  w^ns 
  certain 
  that 
  all 
  the 
  scales 
  in 
  the 
  orchard 
  were 
  established 
  in 
  

   fixed 
  position 
  on 
  the 
  trees. 
  There 
  was 
  an 
  additional 
  advantage 
  in 
  

   waiting 
  until 
  the 
  leaves 
  had 
  fallen, 
  as 
  a 
  smaller 
  quantity 
  of 
  insecti- 
  

   cide 
  would 
  then 
  be 
  required 
  for 
  a 
  thorough 
  treatment 
  of 
  the 
  trees, 
  

   shrubs 
  and 
  hedges 
  on 
  this 
  place. 
  

  

  As 
  Mr. 
  J. 
  C. 
  Blair, 
  of 
  the 
  University 
  Department 
  of 
  Horticulture, 
  

   has 
  had 
  extensive 
  practical 
  experience 
  with 
  spraying 
  methods 
  in 
  the 
  

   orchard. 
  I 
  gladly 
  availed 
  myself 
  of 
  his 
  kind 
  offer 
  to 
  superintend 
  this 
  

   operation 
  for 
  us, 
  and 
  sent 
  him 
  November 
  10 
  on 
  a 
  general 
  trip 
  of 
  in- 
  

   spection 
  tlirough 
  western 
  Illinois, 
  with 
  full 
  instructions 
  as 
  to 
  the 
  dis- 
  

   infection 
  of 
  the 
  Quincy 
  orchard. 
  The 
  insecticide 
  used 
  was 
  whale-oil 
  

   soap 
  obtained 
  from 
  Leggett 
  & 
  Brother, 
  1501 
  Pearl 
  street. 
  New 
  York 
  

   City, 
  at 
  a 
  cost 
  of 
  four 
  cents 
  per 
  pound 
  by 
  the 
  barrel. 
  This 
  soap 
  was 
  

   applied 
  in 
  a 
  hot 
  solution 
  of 
  two 
  pounds 
  to 
  the 
  gallon 
  of 
  water. 
  In 
  

   the 
  operation 
  a 
  large 
  iron 
  pot 
  holding 
  about 
  sixty 
  gallons 
  was 
  

   mounted 
  in 
  the 
  field 
  near 
  the 
  orchard, 
  and 
  in 
  it 
  water 
  was 
  heated 
  

   and 
  the 
  soap 
  dissolved. 
  This 
  soap 
  solution 
  was 
  taken 
  from 
  the 
  pot 
  

   boiling 
  hot 
  and 
  placed 
  in 
  a 
  barrel 
  on 
  a 
  wagon 
  provided 
  with 
  an 
  

   ordinary 
  orchard 
  spray 
  pump 
  and 
  twenty-five 
  feet 
  of 
  hose 
  with 
  a 
  

   good 
  spray 
  nozzle. 
  Three 
  men 
  were 
  required 
  for 
  the 
  work; 
  one
