  PLATE 
  6 
  

  

  Views 
  of 
  three 
  trees, 
  one 
  treated 
  with 
  kerosene, 
  one 
  with 
  whale 
  oil 
  

   soap 
  and 
  the 
  other 
  with 
  crude 
  petroleum. 
  Tree 
  20 
  was 
  very 
  badly 
  in- 
  

   fested 
  with 
  the 
  scale, 
  tree 
  no 
  had 
  very 
  httle 
  of 
  the 
  pest 
  and 
  tree 
  114 
  is 
  

   represented 
  as 
  it 
  appeared 
  at 
  the 
  beginning 
  of 
  the 
  experiment. 
  

  

  PLATE 
  7 
  

  

  Tree 
  51 
  shows 
  the 
  comparative 
  harmlessness 
  of 
  20% 
  kerosene, 
  it 
  is 
  in 
  

   nearly 
  full 
  bloom. 
  The 
  leaves 
  are 
  starting 
  on 
  tree 
  93 
  but 
  they 
  have 
  been 
  

   retarded 
  by 
  the 
  crude 
  petroleum. 
  

  

  PLATE 
  8 
  

  

  This 
  plate 
  shows 
  well 
  the 
  difference 
  between 
  crude 
  petroleum 
  and 
  20% 
  

   kerosene. 
  The 
  latter 
  is 
  practically 
  harmless 
  and, 
  as 
  the 
  two 
  trees 
  were 
  

   as 
  nearly 
  alike 
  as 
  possible, 
  the 
  plate 
  illustrates 
  very 
  nicely 
  the 
  injury 
  due 
  

   to 
  crude 
  petroleum. 
  

  

  PLATE 
  9 
  

  

  Tree 
  loi 
  was 
  very 
  badly 
  infested 
  with 
  the 
  scale 
  but 
  otherwise 
  the 
  com- 
  

   parison 
  between 
  20% 
  and 
  undiluted 
  crude 
  petroleum 
  is 
  a 
  very 
  just 
  one. 
  

  

  PLATE 
  10 
  

  

  Note 
  the 
  killing 
  of 
  branches 
  which 
  seems 
  to 
  be 
  characteristic 
  

   of 
  the 
  undiluted 
  crude 
  petroleum 
  such 
  as 
  was 
  used. 
  

  

  PLATE 
  II 
  

  

  Shows 
  the 
  comparative 
  injury 
  due 
  to 
  December 
  and 
  February 
  applica- 
  

   tions 
  of 
  the 
  oil. 
  

  

  PLATE 
  12 
  

  

  Both 
  trees 
  are 
  in 
  good 
  bloom, 
  showing 
  that 
  an 
  application 
  of 
  whale 
  oil 
  

   soap 
  and 
  petroleum 
  combined 
  does 
  not 
  injure 
  the 
  buds.

  tent 
  in 
  operation, 
  the 
  hood 
  was 
  kept 
  extended 
  for 
  the 
  pur- 
  

   pose 
  of 
  securing 
  greater 
  constancy 
  in 
  the 
  cubic 
  contents 
  of 
  the 
  tent.
