  the 
  same 
  condition 
  regarding 
  scale 
  infestation 
  as 
  the 
  one 
  with 
  

   crude 
  petroleum. 
  On 
  the 
  other 
  hand, 
  the 
  soap 
  has 
  some 
  value 
  as 
  a 
  ferti- 
  

   lizer 
  and 
  is 
  undoubtedly 
  safer 
  to 
  use 
  than 
  even 
  the 
  mechanical 
  emulsions 
  

   of 
  crude 
  oil. 
  There 
  was 
  little 
  perceptible 
  difference 
  between 
  the 
  2 
  and 
  

   the 
  I 
  J 
  pound 
  solutions. 
  The 
  summer 
  spraying 
  with 
  i 
  pound 
  to 
  5 
  gal- 
  

   lons 
  of 
  water 
  proved 
  very 
  effective 
  in 
  killing 
  young 
  scales, 
  but 
  it 
  would 
  

   have 
  to 
  be 
  repeated 
  at 
  intervals 
  of 
  about 
  10 
  days 
  in 
  order 
  to 
  obtain 
  the 
  

   best 
  results. 
  There 
  was 
  some 
  difference 
  between 
  the 
  behavior 
  of 
  Leg- 
  

   gett's 
  and 
  Good's 
  whale 
  oil 
  soap 
  after 
  their 
  application, 
  but 
  the 
  experi- 
  

   ment 
  was 
  not 
  protracted 
  enough 
  to 
  permit 
  the 
  detection 
  of 
  a 
  greater 
  

   insecticide 
  value 
  in 
  one 
  than 
  in 
  the 
  other. 
  Good's 
  soap 
  is 
  more 
  readily 
  

   soluble 
  than 
  the 
  other, 
  and 
  would 
  be 
  preferable 
  on 
  that 
  account.

  This 
  combination 
  

   gave 
  fully 
  as 
  good 
  results 
  as 
  the 
  whale 
  oil 
  soap 
  solution, 
  but 
  its 
  insecti- 
  

   cidal 
  value 
  was 
  not 
  equal 
  to 
  that 
  of 
  20 
  % 
  mechanical 
  emulsion 
  of 
  crude 
  

   petroleum. 
  It 
  is 
  possible 
  that 
  a 
  larger 
  proportion 
  of 
  petroleum 
  could 
  

   have 
  been 
  used 
  to 
  better 
  advantage.

  Were 
  it 
  not 
  for 
  the 
  excessive 
  cost 
  of 
  tents, 
  

   specially 
  for 
  large 
  trees, 
  no 
  better 
  treatment 
  could 
  be 
  recommended. 
  

   In 
  a 
  large 
  orchard 
  of 
  small 
  trees 
  this 
  would 
  probably 
  prove, 
  in 
  spite 
  of 
  

   the 
  considerable 
  cost 
  of 
  the 
  tents, 
  cheaper 
  in 
  the 
  end 
  than 
  spraying. 
  The 
  

   trees 
  suffered 
  no 
  discoverable 
  injury 
  beyond 
  the 
  sHght 
  browning 
  of 
  a 
  few 
  

   of 
  the 
  more 
  advanced 
  buds 
  on 
  several 
  trees. 
  The 
  records 
  of 
  these 
  experi- 
  

   ments 
  show 
  that 
  fumigation 
  with 
  this 
  gas 
  practically 
  means 
  the 
  annihila- 
  

   tion 
  of 
  the

  very 
  few 
  living 
  young

  found 
  on 
  some 
  of 
  the

  could 
  easily 
  have 
  been,

  probably

  NOTES 
  FOR 
  THE 
  YEAR 
  

  

  The 
  season 
  of 
  1900 
  has 
  not 
  presented 
  much 
  unusual. 
  The 
  depreda- 
  

   tions 
  by 
  the 
  forest 
  tent-caterpillar 
  of 
  last 
  year 
  and 
  the 
  year 
  preceding 
  have 
  

   been 
  continued, 
  and 
  occasionally 
  a 
  new 
  insect 
  has 
  come 
  to 
  notice 
  through 
  

   its 
  destructiveness 
  to 
  some 
  valued 
  plant. 
  Many 
  dead 
  grasshoppers 
  were 
  

   found 
  by 
  George 
  Staplin 
  jr, 
  Mannsville, 
  Jefferson 
  co. 
  They 
  had 
  evident- 
  

   ly 
  been 
  killed 
  by 
  a 
  fungus, 
  which 
  was 
  determined 
  by 
  state 
  botanist 
  Peck 
  

   asMas'sospora 
  cicadina 
  Peck, 
  a 
  species 
  which 
  has 
  hitherto 
  been 
  

   recorded 
  only 
  from 
  the 
  17 
  year 
  cicada, 
  so 
  far 
  as 
  known.
