  Discovery 
  of 
  New 
  Illinois 
  Localities.* 
  

  

  The 
  new 
  Illinois 
  localities 
  found 
  infested 
  by 
  the 
  San 
  Jose 
  scale 
  

   since 
  the 
  publication 
  of 
  my 
  last 
  Report 
  are 
  Dundee, 
  in 
  Kane 
  county, 
  

   Manito, 
  in 
  Mason 
  county, 
  Assumption, 
  in 
  Christian 
  county, 
  a 
  farm 
  

   near 
  Walnut 
  Prairie, 
  in 
  Clark 
  county, 
  one 
  near 
  Worden 
  and 
  another 
  

   near 
  Alhambra, 
  in 
  Madison 
  county, 
  a 
  farm 
  near 
  Mt. 
  Carmel, 
  in 
  Wabash 
  

   county, 
  and 
  town 
  lots 
  in 
  Browns, 
  Edwards 
  county, 
  f 
  More 
  extensive 
  

   occurrence 
  of 
  the 
  scale 
  than 
  hitherto 
  reported 
  was 
  also 
  found 
  at 
  Tower 
  

   Hill, 
  in 
  Shelby 
  county, 
  at 
  Mt. 
  Carmel, 
  in 
  Wabash 
  county, 
  at 
  Richview, 
  

   in 
  Washington 
  county, 
  and 
  especially 
  in 
  the 
  Sparta 
  neighborhood, 
  in 
  

   Randolph 
  county. 
  Near 
  the 
  place 
  last 
  mentioned 
  it 
  has 
  now 
  been 
  found 
  

   by 
  my 
  inspectors 
  in 
  more 
  than 
  sixty 
  orchards, 
  scattered 
  over 
  an 
  area 
  of 
  

   approximately 
  twenty-five 
  square 
  miles. 
  

  

  At 
  Dundee, 
  in 
  Kane 
  county, 
  the 
  presence 
  of 
  this 
  scale 
  was 
  first 
  

   observed 
  in 
  the 
  course 
  of 
  a 
  general 
  inspection 
  of 
  premises 
  made 
  at 
  the 
  

   request 
  of 
  the 
  owner 
  November 
  8, 
  1897, 
  by 
  Mr. 
  R. 
  W. 
  Braucher, 
  an 
  

   Assistant 
  of 
  this 
  office. 
  In 
  one 
  corner 
  of 
  an 
  eight-acre 
  lot 
  was 
  a 
  small 
  

   block 
  containing 
  about 
  two 
  thousand 
  trees 
  and 
  shrubs 
  of 
  various 
  kinds, 
  

   including 
  apple, 
  peach, 
  plum, 
  cherry, 
  gooseberry, 
  and 
  currant, 
  and 
  a 
  

   considerable 
  variety 
  of 
  deciduous 
  trees. 
  This 
  block 
  was 
  slightly 
  infested 
  

   with 
  the 
  San 
  Jose 
  scale, 
  occurring 
  mainly 
  on 
  the 
  apple, 
  although 
  a 
  few 
  

   were 
  detected 
  on 
  peach 
  and 
  mountain-ash. 
  The 
  infested 
  apple-trees 
  

   came 
  originally 
  from 
  a 
  nursery 
  in 
  Missouri 
  some 
  two 
  or 
  three 
  years, 
  

   before. 
  It 
  was 
  difficult 
  to 
  believe, 
  however, 
  that 
  they 
  were 
  infested 
  

   when 
  received, 
  because 
  of 
  the 
  comparative 
  scarcity 
  of 
  the 
  scale 
  upon 
  

   them 
  when 
  discovered 
  in 
  the 
  fall 
  of 
  1897. 
  None 
  of 
  them 
  were 
  badly 
  

   attacked, 
  although 
  in 
  some 
  cases 
  the 
  scale 
  was 
  well 
  distributed 
  through 
  

   the 
  top 
  of 
  the 
  tree. 
  A 
  row 
  of 
  apple-trees 
  eight 
  or 
  ten 
  years 
  old 
  

   adjoined 
  this 
  block 
  at 
  one 
  end, 
  and 
  short 
  rows 
  of 
  young 
  cherry 
  and 
  

   pear 
  were 
  separated 
  from 
  it, 
  at 
  a 
  considerable 
  distance, 
  by 
  beds 
  of 
  

   young 
  evergreens. 
  Rose-bushes, 
  syringas, 
  spiraeas, 
  grape-vines, 
  goose- 
  

   berries, 
  currants, 
  plums, 
  apricots, 
  hard 
  maples, 
  and 
  ornamental 
  shrubs, 
  

   were 
  growing 
  on 
  various 
  parts 
  of 
  this 
  eight-acre 
  lot, 
  but 
  no 
  trace 
  of 
  the 
  

   San 
  Jose 
  scale 
  was 
  detected 
  on 
  any 
  of 
  them.|

  To 
  the 
  above 
  should 
  be 
  added 
  the 
  following 
  localities, 
  discovered 
  since 
  this 
  

   manuscript 
  was 
  prepared: 
  Monticello, 
  in 
  Piatt 
  county, 
  a 
  farm 
  near 
  Quincy, 
  in 
  

   Adams 
  county, 
  Summerfield, 
  in 
  St. 
  Clair 
  courty, 
  and 
  Albion, 
  in 
  Edwards 
  county. 
  

  

  J 
  These 
  premises 
  have 
  since 
  been 
  completely 
  cleared 
  of 
  the 
  scale 
  by 
  a 
  destruction 
  

   of 
  everything 
  on 
  the 
  infested 
  place 
  which 
  could 
  harbor 
  it.
