  The 
  leaves 
  on 
  tree 
  66 
  are 
  rather 
  thin 
  and 
  small 
  and 
  largely 
  

   at 
  the 
  tips 
  of 
  the 
  twigs. 
  The 
  entire 
  top 
  of 
  tree 
  67 
  is 
  dead, 
  but 
  the 
  buds 
  

   are 
  starting 
  on 
  the 
  trunk.

  July

  A 
  few 
  living 
  young 
  scales 
  are 
  found 
  on 
  trees 
  62-64, 
  67, 
  75, 
  

   76, 
  97 
  and 
  98. 
  They 
  are 
  rather 
  abundant 
  on 
  trees 
  65, 
  77, 
  96, 
  99 
  and 
  

   100, 
  and 
  very 
  abundant 
  on 
  trees 
  66 
  and 
  68.

  Trees 
  62-68 
  are 
  sprayed 
  with

   using 
  I 
  pound 
  to 
  5 
  gallons 
  of 
  water. 
  

  

  July 
  30. 
  All 
  the 
  scales 
  are 
  apparently 
  dead 
  on 
  trees 
  62 
  and 
  67, 
  and 
  

   most 
  of 
  them 
  have 
  been 
  killed 
  on 
  trees 
  6;^ 
  and 
  64, 
  some 
  are 
  dead 
  on 
  

   trees 
  65 
  and 
  66, 
  and 
  on 
  tree 
  68 
  the 
  result 
  is 
  doubtful. 
  

  

  Aug.

  There 
  are 
  very 
  few 
  or 
  no 
  young 
  on 
  trees 
  62, 
  6^, 
  67, 
  75, 
  97 
  

   and 
  98, 
  and 
  few 
  on 
  trees 
  76, 
  77, 
  96, 
  99 
  and 
  100. 
  Living 
  young 
  are 
  

   rather 
  numerous 
  on 
  the 
  badly 
  infested 
  limbs 
  of 
  trees 
  64 
  and 
  65 
  and 
  are 
  

   abundant 
  on 
  trees 
  66 
  and 
  68. 
  

  

  Sep.

  There 
  are 
  few 
  living 
  young 
  on 
  trees 
  62, 
  96, 
  99 
  and 
  100 
  and 
  

   very 
  few 
  on 
  trees 
  62,, 
  75-77? 
  97 
  and 
  98. 
  They 
  are 
  very 
  abundant 
  on 
  

   trees 
  64, 
  65 
  and 
  95 
  and 
  exceedingly 
  so 
  on 
  trees 
  66 
  and 
  68. 
  The 
  latter 
  

   was 
  in 
  an 
  exceedingly 
  bad 
  condition 
  last 
  spring. 
  Tree 
  67 
  has 
  been 
  cut 
  

   back 
  to 
  a 
  mere 
  stump. 
  

  

  Fumigation 
  with 
  hydrocyanic 
  acid 
  gas, 
  for 
  San 
  Jose 
  scale. 
  

  

  A 
  series 
  of 
  tests 
  were 
  made 
  with 
  this 
  substance 
  for 
  the 
  purpose 
  of 
  ascer- 
  

   taining 
  its 
  efficiency 
  and 
  practicability 
  in 
  this 
  latitude. 
  A 
  canvas 
  tent 
  

   6x6x8 
  feet 
  with 
  a 
  fixed 
  pyramidal 
  hood 
  7 
  feet 
  high 
  was 
  constructed 
  of 
  8 
  

   ounce 
  duck 
  thoroughly 
  oiled 
  with 
  boiled 
  linseed 
  oil. 
  The 
  rectangular 
  

   part 
  of 
  the 
  tent 
  was 
  supported 
  on 
  a 
  light, 
  wooden 
  frame 
  in 
  order 
  to 
  reduce 
  

   the 
  variation 
  in 
  cubic 
  contents 
  as 
  much 
  as 
  practicable. 
  The 
  tent 
  was 
  

   lifted 
  with 
  a 
  30 
  foot 
  pole 
  and 
  an 
  8 
  foot 
  gaff, 
  and 
  thus 
  dropped 
  over 
  the 
  

   tree 
  to 
  be 
  fumigated. 
  The 
  hood 
  was 
  kept 
  extended 
  during 
  the 
  process 
  of 
  

   fumigation 
  as 
  shown 
  on 
  plate 
  13, 
  which 
  also 
  illustrates 
  the 
  manner 
  

   of 
  guying 
  the 
  pole 
  and 
  tent. 
  The 
  tent 
  and 
  apparatus 
  for 
  handling 
  it 
  cost 
  

   $;^8. 
  A 
  number 
  could 
  undoubtedly 
  be 
  made 
  for 
  less 
  pro 
  rata. 
  Prof. 
  W. 
  

   O.Johnson 
  states 
  that 
  such 
  tents 
  can 
  be 
  procured 
  in 
  Maryland 
  for 
  $12, 
  

   /which 
  is 
  much 
  lower 
  than 
  any 
  figure 
  quoted 
  in 
  Albany, 
  but 
  probably 
  this 
  

   would 
  not 
  hold 
  in 
  Maryland 
  since 
  the 
  marked 
  advance 
  in 
  prices. 
  A 
  farmer 
  

   could 
  get 
  a 
  good 
  pole 
  and 
  gaff 
  from 
  near-by 
  woods 
  at 
  much 
  less 
  than 
  the 
  

   market 
  price. 
  The 
  bottom 
  of 
  the 
  tent 
  was 
  provided 
  with 
  a 
  sod 
  cloth, 
  a 
  

   flap 
  some 
  6 
  to 
  8 
  inches 
  wide, 
  which 
  was 
  covered 
  with 
  earth 
  in 
  order 
  to
