  Schenectady 
  county 
  (Paul 
  Roach, 
  Quaker 
  Street) 
  — 
  Tent-caterpillars 
  

   [Clisiocampa 
  americana] 
  are 
  just 
  hatching 
  on 
  the 
  sunny 
  side 
  of 
  

   the 
  egg 
  clusters. 
  On 
  the 
  8th 
  they 
  were 
  active 
  and 
  feeding 
  on 
  the 
  buds, 
  

   and 
  that 
  night 
  we 
  had 
  a 
  hail 
  storm, 
  and 
  on 
  the 
  9th 
  it 
  was 
  cold 
  and 
  

   windy, 
  and 
  they 
  seemed 
  dormant 
  but 
  hugged 
  closer 
  together. 
  On 
  the 
  

   night 
  of 
  the 
  9th 
  ice 
  one 
  half 
  inch 
  thick 
  was 
  formed, 
  and 
  on 
  the 
  morning 
  of 
  

   the 
  loth 
  the 
  caterpillars 
  were 
  still 
  alive, 
  but 
  they 
  seem 
  dormant, 
  and, 
  if 
  

   the 
  cold 
  spell 
  lasts 
  a 
  few 
  days, 
  I 
  think 
  that 
  many 
  will 
  starve 
  to 
  death. 
  

   Eggs 
  of 
  the 
  white 
  marked 
  tussock 
  moth 
  [Notolophus 
  leuco- 
  

   stigma] 
  are 
  quite 
  numerous.

  The 
  forest 
  tent-caterpillar 
  

   [Clisiocampa 
  disstria] 
  has 
  worked 
  havoc 
  in 
  orchards 
  here, 
  

   some 
  being 
  as 
  bare 
  as 
  in 
  midwinter. 
  The 
  appletrees 
  suffered 
  most, 
  next 
  

   plum, 
  pear 
  and 
  cherry. 
  Forest 
  trees 
  are 
  attacked 
  in 
  the 
  order 
  named 
  : 
  

   ash, 
  linden, 
  elm, 
  and 
  maple. 
  Some 
  of 
  the 
  caterpillars 
  died 
  of 
  a 
  disease; 
  

   about 
  May 
  25 
  the 
  rest 
  began 
  to 
  spin 
  their 
  cocoons. 
  At 
  this 
  time 
  a 
  

   cold 
  storm 
  came 
  on, 
  and 
  but 
  very 
  few 
  cocoons 
  can 
  be 
  found. 
  My 
  

   orchard 
  and 
  shade 
  trees 
  were 
  sprayed 
  with 
  arsenate 
  of 
  lead, 
  and, 
  while 
  

   great 
  clusters 
  of 
  worms 
  can 
  be 
  found 
  on 
  the 
  trees, 
  the 
  caterpillars 
  have 
  

   eaten 
  but 
  little, 
  some 
  not 
  at 
  all. 
  It 
  is 
  cheap, 
  easy 
  of 
  application, 
  efficient, 
  

   and 
  with 
  me 
  has 
  not 
  burned 
  the 
  foliage 
  of 
  Japanese 
  plums, 
  the 
  tenderest 
  

   of 
  all.

  — 
  The 
  appletree 
  tent- 
  

   caterpillar 
  [Clisiocampa 
  americana] 
  is 
  appearing 
  in 
  great 
  numbers 
  

   this 
  spring. 
  I 
  have 
  also 
  found 
  many 
  forest 
  tent-caterpillars 
  [Clisio- 
  

   campa 
  disstria]. 
  May 
  10. 
  The 
  cold 
  and 
  frost 
  of 
  last 
  week 
  has 
  

   checked 
  the 
  caterpillars. 
  May 
  19. 
  The 
  forest 
  tent-caterpillars 
  are 
  doing 
  

   very 
  much 
  damage. 
  They 
  are 
  attacking 
  the 
  plum 
  and 
  other 
  fruit 
  trees.

  Appletree 
  bark 
  louse 
  [Mytilaspis 
  pomorum] 
  is 
  very 
  

   thick 
  on 
  poplar 
  and 
  willow. 
  There 
  is 
  now 
  considerable 
  variation 
  in 
  the 
  

   size 
  of 
  forest 
  tent- 
  caterpillars 
  ; 
  some 
  are 
  full 
  grown 
  and 
  others 
  half 
  the 
  size. 
  

   June 
  I. 
  Forest 
  tent-caterpillars 
  are 
  spinning 
  their 
  cocoons. 
  They 
  have 
  

   done 
  a 
  great 
  deal 
  of 
  damage 
  this 
  year, 
  stripping 
  the 
  foliage 
  from 
  many 
  

   trees 
  and 
  then 
  attacking 
  the 
  new 
  growth.

  The 
  moths 
  of 
  

   [Clisiocampa 
  disstria] 
  are 
  appearing 
  in 
  great 
  numbers. 
  In 
  a 
  

   place 
  5 
  miles 
  square 
  I 
  think 
  there 
  are 
  500 
  acres 
  of 
  woods 
  which 
  have 
  

   been 
  defoliated 
  by 
  the 
  forest 
  tent-caterpillars.
