  Tree 
  93 
  is 
  nearly 
  dead. 
  Dried 
  leaves 
  are 
  hanging 
  from 
  the 
  

   limbs, 
  though 
  the 
  bark 
  on 
  the 
  trunk 
  is 
  green 
  up 
  to 
  about 
  four 
  feet 
  from 
  

   the 
  ground. 
  A 
  sprout 
  is 
  starting

  The 
  conditions 
  are 
  nearly 
  the 
  same 
  as 
  on 
  Sep.

  The 
  above 
  is 
  a 
  ghastly 
  record 
  for 
  a 
  substance 
  which 
  has 
  been 
  pro- 
  

   nounced 
  " 
  harmless 
  to 
  the 
  most 
  tender 
  varieties 
  and 
  on 
  the 
  youngest 
  

   trees.'^ 
  It 
  was 
  therefore 
  with 
  great 
  pleasure 
  that 
  I 
  availed 
  myself 
  of 
  the 
  

   opportunity 
  to 
  watch 
  the 
  outcome 
  of 
  several 
  experiments 
  tried 
  by 
  L. 
  L. 
  

   Morrell, 
  of 
  Kinderhook 
  (N. 
  Y.). 
  Crude 
  petroleum 
  was 
  painted 
  on 
  the 
  

   trunks 
  of 
  some 
  of 
  the 
  young 
  trees, 
  top-worked 
  with 
  Sutton 
  beauty 
  

   apples, 
  and 
  later, 
  Ap., 
  the 
  tops 
  of 
  the 
  trees 
  were 
  sprayed 
  with 
  a 
  25% 
  

   mechanical 
  emulsion 
  of 
  crude 
  petroleum. 
  Many 
  of 
  the 
  lateral 
  buds 
  in 
  

   these 
  trees 
  were 
  dead 
  May 
  21 
  and 
  the 
  foliage 
  looked 
  sickly. 
  Since 
  then 
  

   portions 
  of 
  some 
  of 
  the 
  trees 
  have 
  died. 
  Their 
  injury 
  was 
  in 
  all 
  prob- 
  

   ability 
  caused 
  by 
  the 
  liberal 
  amount 
  of 
  oil 
  put 
  on 
  with 
  the 
  brush. 
  June 
  

   20 
  Mr 
  Morrell 
  reported 
  that 
  the 
  tops 
  of 
  some 
  of 
  these 
  trees 
  had 
  com- 
  

   menced 
  to 
  die, 
  and 
  that 
  a 
  number 
  of 
  them 
  looked 
  sickly. 
  The 
  results 
  of 
  

   painting 
  a 
  tree-top 
  worked 
  with 
  Sutton 
  beauty 
  with 
  crude 
  petroleum 
  

   about 
  the 
  middle 
  of 
  February 
  is 
  well 
  shown 
  on 
  pi. 
  11, 
  which 
  was 
  taken 
  

   May 
  21. 
  The 
  foliage 
  was 
  very 
  thin, 
  and 
  the 
  leaves 
  were 
  small 
  and 
  

   unhealthy. 
  June 
  2, 
  with 
  few 
  exceptions, 
  they 
  looked 
  well, 
  as 
  stated 
  by 
  

   Mr 
  Morrell. 
  

  

  The 
  most 
  disastrous 
  results 
  were 
  seen 
  in 
  the 
  king 
  trees 
  painted 
  with 
  

   crude 
  petroleum 
  Dec. 
  i, 
  1899. 
  One 
  was 
  photographed 
  May 
  21 
  (pi. 
  11) 
  

   and 
  was 
  then 
  nearly 
  dead. 
  June 
  20 
  the 
  trees 
  so 
  treated 
  were 
  dead 
  

   to 
  all 
  appearances. 
  

  

  Experiments

  scale. 
  

  

  Two 
  makes 
  of 
  this 
  insecticide 
  were 
  experimented 
  with 
  and 
  the 
  results 
  

   compared. 
  One 
  was
