  The 
  records 
  for 
  the 
  winter 
  of 
  1911-1*2 
  are 
  not 
  given, 
  as 
  it 
  was 
  

   impossible 
  to 
  secure 
  the 
  information 
  from 
  some 
  of 
  the 
  cities 
  men- 
  

   tioned. 
  The 
  data 
  concerning 
  the 
  infestation 
  in 
  cities 
  and 
  towns 
  in 
  

   Massachusetts 
  have 
  been 
  kindly 
  furnished 
  by 
  State 
  Forester 
  F. 
  W. 
  

   Kane 
  and 
  his 
  assistants, 
  while 
  similar 
  data 
  from 
  the 
  other 
  States 
  

   have 
  been 
  supplied 
  by 
  Mr. 
  Rogers. 
  It 
  will 
  be 
  noted 
  that 
  the 
  city 
  

   of 
  Brockton 
  was 
  found 
  infested 
  in 
  1905-6 
  and 
  that 
  the 
  same 
  is 
  

   I 
  rue 
  of 
  Portsmouth, 
  N. 
  H. 
  An 
  excellent 
  opportunity 
  is 
  offered 
  for 
  

   comparing 
  the 
  number 
  of 
  egg 
  clusters 
  found 
  in 
  these 
  two 
  cities 
  from 
  

   year 
  to 
  year. 
  It 
  will 
  be 
  observed 
  that 
  at 
  the 
  end 
  of 
  the 
  fifth 
  year 
  

   1,575 
  egg 
  clusters 
  were 
  found 
  in 
  Brockton, 
  while 
  over 
  72,000 
  were 
  

   treated 
  in 
  Portsmouth, 
  N. 
  H. 
  This 
  indicates 
  very 
  strongly 
  that 
  new 
  

   infestations 
  were 
  continually 
  being 
  brought 
  about 
  through 
  the 
  spread 
  

   of 
  caterpillars 
  by 
  the 
  wind. 
  

  

  Somewhat 
  the 
  same 
  conditions 
  will 
  be 
  noted 
  on 
  comparing 
  the 
  

   record 
  of 
  infestation 
  at 
  Worcester 
  with 
  that 
  of 
  Nashua, 
  Manchester, 
  

   and 
  Concord. 
  The 
  increase 
  in 
  Worcester 
  for 
  the 
  period 
  shown 
  in 
  

   the 
  table 
  is 
  slightly 
  less 
  than 
  that 
  in 
  Brockton, 
  which 
  shows 
  that 
  

   the 
  wind 
  was 
  more 
  favorable 
  for 
  spread 
  in 
  the 
  direction 
  of 
  the 
  latter 
  

   city. 
  

  

  It 
  should 
  be 
  noted 
  that 
  all 
  the 
  newly 
  infested 
  points 
  were 
  treated 
  

   each 
  year, 
  and 
  in 
  many 
  cases 
  colonies 
  were 
  exterminated, 
  but 
  as 
  a 
  

   rule 
  a 
  larger 
  number 
  of 
  new 
  infestations 
  were 
  found 
  in 
  different 
  

   parts 
  of 
  the 
  cities 
  the 
  next 
  year, 
  and 
  the 
  total 
  of 
  egg 
  clusters 
  usually 
  

   showed 
  an 
  increase. 
  

  

  In 
  connection 
  with 
  these 
  data 
  it 
  is 
  interesting 
  to 
  consider 
  the 
  

   record 
  of 
  infestation 
  in 
  the 
  State 
  of 
  Rhode 
  Island. 
  The 
  gipsy 
  moth 
  

   was 
  first 
  found 
  in 
  the 
  city 
  of 
  Providence 
  in 
  1901, 
  and 
  some 
  work 
  

   was 
  done 
  to 
  control 
  the 
  insect 
  during 
  the 
  five 
  succeeding 
  years. 
  

  

  In 
  1906-7 
  a 
  careful 
  examination 
  was 
  made 
  by 
  agents 
  of 
  the 
  Bureau 
  

   of 
  Entomology 
  in 
  cooperation 
  with 
  the 
  State 
  of 
  Rhode 
  Island, 
  and 
  

   several 
  towns 
  surrounding 
  that 
  cit}^ 
  were 
  found 
  infested. 
  In 
  all. 
  

   79,000 
  egg 
  clusters 
  were 
  found 
  and 
  treated. 
  In 
  1907-8, 
  7,500 
  egg 
  

   .lusters 
  were 
  found, 
  and 
  the 
  following 
  winter 
  only 
  1,164 
  were 
  dis- 
  

   covered. 
  During 
  the 
  next 
  two 
  winters 
  there 
  was 
  a 
  slight 
  increase 
  

   in 
  the 
  number 
  of 
  egg 
  clusters 
  found, 
  as 
  several 
  newly 
  infested 
  places 
  

   were 
  discovered. 
  No 
  work 
  was 
  done 
  in 
  the 
  summer 
  of 
  L911, 
  because 
  

   the 
  State 
  failed 
  to 
  provide 
  the 
  necessary 
  funds. 
  During 
  the 
  winter 
  

   of 
  1 
  *> 
  1 
  1 
  12 
  an 
  examination 
  made 
  by 
  the 
  agents 
  of 
  the 
  Bureau 
  of 
  

   Entomology 
  showed 
  that 
  the 
  insect 
  had 
  increased 
  rapidly. 
  37,293 
  

   egg 
  clusters 
  Inning 
  been 
  found 
  and 
  five 
  new 
  towns 
  having 
  been 
  

   infested. 
  

  

  The 
  territory 
  infested 
  includes 
  both 
  city 
  and 
  country, 
  and 
  the 
  

  

  figures 
  show 
  how 
  rapidly 
  rein 
  testation 
  takes 
  place 
  after 
  suppression 
  

   work 
  is 
  stopped. 
  The 
  data 
  also 
  indicate 
  that 
  the 
  rate 
  of 
  increase 
  is
