  tyre. 
  The 
  work 
  in 
  Wareham 
  was 
  carried 
  on 
  under 
  the 
  direction 
  of 
  

   C. 
  E. 
  Tot 
  man 
  and 
  C. 
  B. 
  Whitaker, 
  while 
  that 
  in 
  Gardner 
  was 
  di- 
  

   rected 
  by 
  Henry 
  N. 
  Bean. 
  It 
  should 
  be 
  noted 
  at 
  the 
  outset 
  that 
  the 
  

   character 
  of 
  the 
  forest 
  has 
  a 
  great 
  influence 
  on 
  the 
  liability 
  to 
  infesta- 
  

   tion, 
  because 
  if 
  the 
  caterpillars 
  are 
  carried 
  by 
  the 
  wind 
  and 
  dropped 
  

   upon 
  trees 
  upon 
  which 
  they 
  can 
  not 
  feed, 
  no 
  infestation 
  wall 
  result. 
  

   Therefore 
  it 
  is 
  to 
  be 
  expected 
  that 
  in 
  sections 
  where 
  coniferous 
  trees 
  

   predominate 
  the 
  chances 
  of 
  new 
  infestation 
  will 
  diminish, 
  even 
  al- 
  

   though 
  the 
  region 
  is 
  in 
  line 
  with 
  the 
  prevailing 
  wind 
  during 
  the 
  time 
  

   the 
  caterpillars 
  are 
  likely 
  to 
  be 
  carried 
  by 
  it. 
  

  

  RECORD 
  OF 
  SCOUTING 
  IN 
  LISBON, 
  ME. 
  

  

  On 
  October 
  23, 
  1911, 
  the 
  work 
  in 
  Lisbon, 
  Me., 
  was 
  begun 
  by 
  Mr. 
  

   C. 
  E. 
  Totman 
  and 
  a 
  crew 
  of 
  experienced 
  scouts, 
  and 
  the 
  territory 
  

   north 
  of 
  the 
  Androscoggin 
  River 
  and 
  east 
  of 
  the 
  Maine 
  Central 
  

   Railroad 
  was 
  examined. 
  This 
  covered 
  about 
  16^ 
  square 
  miles, 
  about 
  

   40 
  per 
  cent 
  of 
  which 
  was 
  woodland. 
  The 
  land 
  in 
  this 
  town 
  is 
  rolling, 
  

   and 
  a 
  considerable 
  portion 
  is 
  cleared 
  and 
  cultivated. 
  

  

  The 
  percentages 
  of 
  the 
  various 
  kinds 
  of 
  trees 
  in 
  the 
  regions 
  scouted 
  

   were 
  estimated 
  by 
  Mr. 
  Totman, 
  as 
  follows 
  : 
  

  

  IVr

  It 
  will 
  be 
  noted 
  that 
  about 
  half 
  of 
  the 
  food 
  plants 
  (conifers 
  and 
  

   ash) 
  are 
  unsuitable 
  for 
  food 
  for 
  first-stage 
  gipsy-moth 
  caterpillars 
  

   so 
  that 
  of 
  the 
  16^ 
  square 
  miles 
  covered 
  only 
  3j 
  square 
  miles 
  of 
  the 
  

   area 
  supported 
  trees 
  upon 
  which 
  the 
  gipsy 
  moth 
  would 
  survive 
  if 
  

   it 
  were 
  introduced. 
  The 
  oak, 
  which 
  is 
  the 
  favorite 
  food, 
  comprised 
  

   only 
  3 
  per 
  cent 
  of 
  the 
  tree 
  growth. 
  Roadsides 
  in 
  this 
  town 
  

   were 
  scouted 
  in 
  the 
  winter 
  of 
  1910-11, 
  and 
  nine 
  infestations 
  were 
  

   found 
  in 
  the 
  territory 
  under 
  consideration, 
  a 
  single 
  egg 
  cluster 
  

   being 
  obtained 
  in 
  each 
  locality. 
  These 
  were 
  treated 
  at 
  the 
  time. 
  

   The 
  results 
  of 
  the 
  present 
  scouting 
  showed 
  that 
  no 
  infestations 
  were 
  

   present 
  where 
  eggs 
  were 
  found 
  last 
  year, 
  but 
  IS 
  new 
  infestations 
  

   were 
  located. 
  Only 
  one 
  of 
  these 
  was 
  in 
  woodland, 
  and 
  in 
  this 
  case 
  

   seven 
  egg 
  clusters 
  were 
  found 
  on 
  the 
  bank 
  of 
  the 
  Sabattus 
  River. 
  

   Thirteen 
  vgg 
  clusters 
  were 
  found 
  on 
  trees 
  along 
  the 
  roadside, 
  easl 
  

   of 
  the 
  town, 
  and 
  two 
  were 
  located 
  on 
  another 
  road 
  near 
  by. 
  Each 
  

  

  of 
  the 
  remaining 
  infestations 
  at 
  different 
  points 
  along 
  the 
  highway 
  

   contained 
  a 
  single 
  vgg 
  cluster 
  or 
  a 
  pupal 
  case. 
  It 
  is 
  improbable 
  

   that 
  the 
  infestations 
  along 
  these 
  roads 
  resulted 
  from 
  previous 
  in- 
  

   festations, 
  although 
  a 
  few 
  egg 
  cluster- 
  may 
  have 
  been 
  overlooked. 
  

   Lisbon 
  is 
  located 
  at 
  least 
  70 
  miles 
  from 
  badly 
  infested 
  territory, 
  30 
  

   that 
  bad 
  woodland 
  infestations 
  were 
  hardly 
  to 
  be 
  expected.
