  ance 
  from 
  one 
  locality 
  to 
  another. 
  The 
  continued 
  exercise 
  of 
  vigi- 
  

   lance 
  by 
  both 
  state 
  and 
  national 
  authorities 
  may 
  perhaps 
  delay 
  the 
  

   invasion 
  of 
  this 
  State 
  for 
  a 
  decade 
  or 
  more. 
  The 
  warning 
  placard 
  

   illustrating 
  both 
  this 
  species 
  and 
  the 
  brown 
  tail 
  moth, 
  has 
  b'een 
  

   conspicuously 
  posted 
  in 
  many 
  post 
  offices 
  and 
  other 
  public 
  places 
  

   located 
  in 
  portions 
  of 
  the 
  State 
  where 
  the 
  pest 
  is 
  most 
  liable 
  to 
  

   appear. 
  Additional 
  copies 
  are 
  on 
  hand 
  and 
  can 
  be 
  used 
  to 
  replace 
  

   those 
  broken 
  or 
  lost 
  and 
  also 
  for 
  sending 
  to 
  other 
  localities 
  should 
  

   future 
  developments 
  warrant 
  such 
  procedure. 
  

  

  A 
  better 
  idea 
  of 
  what 
  gipsy 
  moth 
  infestation 
  means 
  may 
  be 
  

   gained 
  from 
  the 
  following 
  notes 
  made 
  June 
  24, 
  while 
  examining 
  

   conditions 
  in 
  the 
  infested 
  territory. 
  Starting 
  from 
  Boston 
  we 
  

   passed 
  through 
  Cambridge 
  and 
  Brookline 
  to 
  Waltham, 
  observing 
  

   in 
  particular 
  conditions 
  in 
  Waltham 
  park. 
  This 
  latter 
  comprises 
  

   over 
  100 
  acres 
  of 
  rocky 
  land 
  mostly 
  covered 
  with 
  a 
  dense 
  growth 
  

   of 
  oaks 
  some 
  20 
  to 
  40 
  feet 
  high. 
  No 
  winter 
  work 
  such 
  as 
  creo- 
  

   soting 
  Qgg 
  masses 
  on 
  trees 
  and 
  clearing 
  out 
  underbrush 
  was 
  done, 
  

   though 
  the 
  whole 
  was 
  rather 
  badly 
  infested. 
  The 
  entire 
  park 
  was 
  

   sprayed 
  with 
  poison 
  with 
  one 
  of 
  the 
  giant 
  outfits 
  described 
  below, 
  

   though 
  the 
  application 
  was 
  made 
  rather 
  late. 
  The 
  results 
  were 
  

   very 
  gratifying, 
  since 
  practically 
  no 
  trees 
  were 
  seriously 
  injured 
  

   by 
  caterpillars, 
  though 
  the 
  park 
  is 
  surrounded 
  by 
  badly 
  infested 
  

   territory. 
  The 
  policy 
  has 
  been 
  to 
  safeguard 
  such 
  treated 
  areas 
  by 
  

   clearing 
  a 
  strip 
  about 
  100 
  feet 
  wide 
  around 
  the 
  entire 
  border. 
  This 
  

   is 
  done 
  by 
  cutting 
  out 
  and 
  burning 
  all 
  underbrush 
  and 
  then 
  apply- 
  

   ing 
  tree 
  Tanglefoot 
  to 
  the 
  trunks 
  of 
  the 
  remaining 
  trees, 
  so 
  as 
  to 
  

   prevent 
  caterpillars 
  from 
  ascending 
  the 
  trees. 
  The 
  latter 
  do 
  not, 
  

   as 
  a 
  rule, 
  pass 
  this 
  barrier, 
  though 
  at 
  the 
  time 
  of 
  our 
  visit 
  some 
  

   were 
  entering 
  the 
  park 
  and 
  supplementary 
  spraying 
  was 
  necessary 
  

   here 
  and 
  there 
  in 
  order 
  to 
  prevent 
  further 
  damage. 
  Continuing 
  

   from 
  Waltham 
  we 
  passed 
  through 
  Arlington, 
  Winchester 
  and 
  

   Stoneham 
  to 
  Melrose. 
  Here 
  and 
  there 
  along 
  the 
  entire 
  route 
  con- 
  

   siderable 
  woodland 
  areas 
  were 
  stripped 
  or 
  nearly 
  defoliated 
  by 
  

   gipsy 
  moth 
  caterpillars, 
  and 
  in 
  one 
  instance 
  at 
  least, 
  the 
  badly 
  

   affected 
  area 
  was 
  fully 
  a 
  mile 
  and 
  a 
  quarter 
  in 
  length. 
  These 
  

   woodlands 
  were 
  all 
  on 
  hillsides 
  and 
  consisted 
  mostly 
  of 
  oak 
  rang- 
  

   ing 
  from 
  30 
  to 
  50 
  feet 
  or 
  more 
  in 
  hight. 
  These 
  stony 
  hills 
  are 
  

   said 
  to 
  have 
  very 
  little 
  agricultural 
  value, 
  being 
  rated 
  at 
  $15 
  per 
  

   acre. 
  The 
  cost 
  of 
  adequately 
  controlling 
  a 
  pest 
  like 
  the 
  gipsy 
  

   moth 
  in 
  such 
  situations 
  is 
  at 
  once 
  apparent. 
  The 
  general 
  condi-
