  maybe 
  opened 
  sufficiently 
  to 
  cause 
  not 
  only 
  the 
  circulation 
  in 
  the 
  water 
  

   jacket, 
  but 
  also 
  to 
  relieve 
  the 
  increased 
  pressure 
  on 
  the 
  two 
  hose. 
  

  

  Beside 
  the 
  main 
  parts 
  of 
  the 
  outfit, 
  as 
  above 
  mentioned, 
  there 
  are 
  

   two 
  tool 
  boxes, 
  about 
  one 
  hundred 
  and 
  fifty 
  feet 
  of 
  three-ply 
  quarter- 
  

   inch 
  rubber 
  hose, 
  poles 
  and 
  extension 
  rods 
  for 
  spraying 
  higher 
  parts 
  of 
  

   the 
  trees, 
  pails 
  for 
  carrying 
  water, 
  and 
  gasoline 
  cans. 
  

  

  The 
  larger 
  tool 
  box 
  is 
  8.5 
  in. 
  x 
  41 
  in. 
  x 
  32 
  in. 
  outside 
  measure, 
  

   and 
  was 
  made 
  in 
  this 
  form 
  that 
  it 
  might 
  occupy 
  the 
  space 
  between 
  the 
  

   tank 
  and 
  wagon 
  box, 
  on 
  the 
  left, 
  when 
  moving 
  from 
  place 
  to 
  place. 
  In 
  

   this 
  box 
  are 
  the 
  work 
  clothes, 
  a 
  spade, 
  hatchet, 
  nozzles, 
  reducers, 
  

   ■wrenches, 
  wire-cutters, 
  packing, 
  screw-driver, 
  and 
  other 
  articles 
  used 
  

   in 
  connection 
  with 
  the 
  spraying 
  operation. 
  The 
  smaller 
  box 
  is 
  12 
  in. 
  

   X 
  19 
  in. 
  X 
  20 
  in., 
  and 
  was 
  made 
  to 
  occupy 
  the 
  space 
  between 
  the 
  engine 
  

   and 
  the 
  tank. 
  It 
  contains 
  the 
  oils 
  and 
  smaller 
  renewal 
  parts 
  for 
  the 
  

   engine. 
  

  

  A 
  large 
  tarpaulin 
  covers 
  the 
  whole 
  apparatus, 
  and 
  by 
  means 
  of 
  

   short 
  ropes 
  attached 
  to 
  its 
  edges 
  may 
  be 
  securely 
  fastened 
  to 
  the 
  wagon- 
  

   box, 
  so 
  that 
  in 
  shipping, 
  engine, 
  tank, 
  and 
  machinery 
  are 
  all 
  under 
  

   shelter 
  and 
  protected 
  from 
  the 
  weather.

  At 
  Dundee, 
  Kane 
  county, 
  all 
  the 
  trees 
  (apple, 
  peach, 
  and 
  mountain- 
  

   ash) 
  upon 
  which 
  the 
  San 
  Jose 
  scale 
  could 
  be 
  discovered 
  were 
  dug 
  out 
  

   and 
  destroyed 
  in 
  the 
  presence 
  of 
  my 
  Assistant, 
  Mr. 
  R. 
  W. 
  Braucher, 
  

   November 
  20, 
  1897. 
  Everything 
  in 
  the 
  block 
  of 
  trees 
  in 
  which 
  this 
  in- 
  

   fested 
  stock 
  was 
  found 
  was, 
  in 
  fact, 
  so 
  destroyed 
  at 
  this 
  time 
  except 
  

   some 
  shade 
  trees 
  — 
  black 
  walnut, 
  horse 
  chestnut, 
  white 
  elm, 
  hard 
  maple, 
  

   birch, 
  and 
  basswood, 
  and 
  these 
  were 
  thoroughly 
  sprayed 
  with 
  whale-oil 
  

   soap. 
  A 
  few 
  white-ash 
  seedlings 
  in 
  this 
  block 
  were 
  not 
  sprayed. 
  The 
  

   apple-, 
  cherry-, 
  and 
  pear-trees 
  in 
  the 
  vicinity, 
  and 
  scattered 
  soft 
  maples, 
  

   rose-bushes, 
  and 
  syringas 
  next 
  the 
  infested 
  block 
  were 
  sprayed, 
  leaving 
  

   without 
  treatment 
  only 
  the 
  ornamental 
  shrubbery 
  farthest 
  from 
  the 
  trees 
  

   infested. 
  

  

  These 
  premises 
  were 
  very 
  carefully 
  inspected 
  again 
  September 
  7, 
  

   1898, 
  by 
  Mr. 
  E. 
  C. 
  Green, 
  of 
  my 
  office, 
  and 
  still 
  more 
  fully, 
  October 
  

   28 
  and 
  29, 
  1898, 
  by 
  Mr. 
  E. 
  B. 
  Forbes, 
  the 
  first 
  inspection 
  to 
  ascertain, 
  

   for 
  my 
  own 
  information, 
  the 
  effect 
  of 
  the 
  insecticide 
  procedure 
  there, 
  

   and 
  the 
  second, 
  made 
  at 
  the 
  request 
  of 
  the 
  owner, 
  to 
  serve 
  as 
  a 
  basis 
  

   for 
  a 
  certificate 
  of 
  freedom 
  from 
  the 
  San 
  Jose 
  scale 
  and 
  other 
  injurious 
  

   insects 
  and 
  fungous 
  diseases. 
  Both 
  these 
  skilled 
  and 
  careful 
  observers 
  

   reported 
  after 
  this 
  interval 
  of 
  nearly 
  a 
  year 
  from 
  the 
  time 
  of 
  treatment 
  

   that 
  there 
  was 
  no 
  trace 
  of 
  the 
  San 
  Jose 
  scale 
  to 
  be 
  found 
  on 
  these
