  THE 
  DISPERSION 
  OF 
  THE 
  GIPSY 
  MOTH. 
  

  

  In 
  1911-12 
  14 
  woodland 
  infestations 
  of 
  59 
  egg 
  clusters 
  and 
  22 
  

   orchard 
  and 
  roadside 
  infestations 
  of 
  202 
  clusters 
  were 
  found 
  east 
  

   of 
  the 
  railroad. 
  The 
  woodland 
  infestations 
  were 
  in 
  the 
  territory 
  

   between 
  the 
  Milton 
  railroad 
  station 
  and 
  the 
  south 
  end 
  of 
  the 
  town. 
  

   In 
  the 
  part 
  of 
  the 
  town 
  west 
  of 
  the 
  railroad 
  only 
  the 
  roadsides 
  and 
  

   orchards 
  were 
  examined, 
  and 
  6,602 
  egg 
  clusters 
  were 
  found 
  in 
  57 
  

   localities. 
  

  

  The 
  results 
  of 
  scouting 
  in 
  this 
  town 
  show 
  that 
  the 
  infestation 
  is 
  

   increasing 
  rapidly 
  in 
  both 
  woodland 
  and 
  orchards. 
  The 
  figures 
  for 
  

   the 
  two 
  years 
  are 
  significant, 
  for 
  in 
  the 
  western 
  part 
  of 
  the 
  town 
  

   the 
  infested 
  localities 
  in 
  one 
  year 
  more 
  than 
  doubled, 
  and 
  the 
  number 
  

   of 
  egg 
  clusters 
  was 
  more 
  than 
  40 
  times 
  greater 
  than 
  the 
  previous 
  

   year. 
  

  

  RECORD 
  OF 
  SCOUTING 
  IN 
  TILTON, 
  N. 
  H. 
  

  

  Examination 
  of 
  Tilton, 
  N. 
  H., 
  was 
  begun 
  November 
  1, 
  1911, 
  by 
  

   Mr. 
  C. 
  E. 
  Boardman 
  and 
  a 
  crew 
  of 
  experienced 
  scouts. 
  The 
  area 
  

   of 
  the 
  town 
  is 
  about 
  10 
  square 
  miles, 
  less 
  than 
  one-third 
  of 
  this 
  

   being 
  wooded. 
  According 
  to 
  Mr. 
  Boardman's 
  estimates 
  the 
  tree 
  

   growth 
  is 
  as 
  follows:

  In 
  1910-11 
  the 
  roadsides 
  and 
  orchards 
  in 
  the 
  town 
  were 
  scouted, 
  

   and 
  four 
  infestations 
  containing 
  889 
  clusters 
  were 
  found. 
  In 
  one 
  

   of 
  these 
  over 
  800 
  clusters 
  were 
  treated, 
  and 
  during 
  the 
  following 
  

   summer 
  over 
  4,800 
  caterpillars 
  and 
  pupae 
  were 
  destroyed 
  under 
  

   burlap. 
  As 
  a 
  result 
  of 
  the 
  present 
  scout 
  only 
  11 
  egg 
  clusters 
  were 
  

   found 
  in 
  three 
  orchard 
  and 
  two 
  woodland 
  infestations, 
  one 
  of 
  the 
  

   latter 
  being 
  near 
  the 
  bad 
  infestation 
  of 
  the 
  previous 
  year. 
  This 
  

   shows 
  that 
  good 
  work 
  was 
  done 
  in 
  controlling 
  and 
  reducing 
  the 
  

   infestations 
  found 
  and 
  that 
  reinfestation 
  by 
  natural 
  or 
  artificial 
  

   spread 
  in 
  this 
  area 
  has 
  been 
  slow. 
  

  

  Tilton 
  is 
  located 
  20 
  miles 
  north 
  of 
  Concord, 
  N. 
  H., 
  and 
  most 
  of 
  

   the 
  badly 
  infested 
  area 
  lies 
  to 
  the 
  southeast 
  ; 
  some, 
  however, 
  is 
  near 
  

   Concord 
  and 
  extends 
  to 
  the 
  south.

  RECORD 
  OF 
  SCOUTING 
  IN 
  BENNINGTON, 
  N.

  Bennington 
  is 
  located 
  about 
  25 
  miles 
  west 
  of 
  Manchester,

   The 
  land 
  in 
  the 
  eastern 
  part 
  of 
  the 
  town 
  forms 
  a 
  part 
  of 
  the 
  

   watershed 
  of 
  the 
  Merrimac 
  and 
  Contocook 
  Rivers. 
  Almost 
  one-half 
  

   of 
  the 
  area 
  is 
  wooded. 
  An 
  examination 
  of 
  this 
  town 
  was 
  begun
