  caterpillars, 
  and 
  the 
  presence 
  of 
  the 
  insect 
  in 
  woodland 
  surrounding 
  

   lakes 
  and 
  ponds 
  which 
  were 
  frequented 
  by 
  camping 
  parties 
  was 
  the 
  

   natural 
  result. 
  During 
  midsummer, 
  when 
  caterpillars 
  were 
  abun- 
  

   dant, 
  they 
  could 
  frequently 
  be 
  seen 
  crawling 
  on 
  the 
  clothing 
  of 
  

   people 
  on 
  electric 
  cars 
  and 
  sometimes 
  have 
  been 
  observed 
  on 
  the 
  

   seats 
  and 
  running 
  boards. 
  In 
  this 
  way 
  they 
  are 
  often 
  carried 
  consid- 
  

   erable 
  distances. 
  

  

  THE 
  AUTOMOBILE 
  AS 
  A 
  MEANS 
  OF 
  DISPERSING 
  THE 
  GIPSY 
  MOTH. 
  

  

  Perhaps 
  no 
  single 
  form 
  of 
  transportation 
  has 
  caused 
  so 
  wide 
  a 
  

   dispersion 
  of 
  this 
  insect 
  as 
  the 
  automobile. 
  When 
  the 
  gipsy 
  moth 
  

   was 
  most 
  abundant 
  during 
  the 
  nineties 
  it 
  was 
  seldom 
  possible 
  for 
  

   caterpillars 
  to 
  be 
  conveyed 
  on 
  teams 
  or 
  wagons 
  more 
  than 
  20 
  miles 
  

   in 
  a 
  single 
  day, 
  but 
  with 
  the 
  advent 
  of 
  the 
  automobile 
  this 
  danger 
  

   was 
  greatly 
  increased. 
  In 
  fact, 
  since 
  this 
  mode 
  of 
  travel 
  has 
  be- 
  

   come 
  popular 
  the 
  traffic 
  between 
  the 
  cities 
  in 
  eastern 
  Massachusetts 
  

   and 
  the 
  seashore 
  and 
  mountain 
  regions 
  in 
  Maine, 
  New 
  Hampshire, 
  

   and 
  Vermont 
  has 
  increased 
  remarkably, 
  and 
  the 
  spread 
  of 
  the 
  insect 
  

   has 
  been 
  proportionately 
  greater. 
  

  

  The 
  lines 
  of 
  automobile 
  travel 
  are 
  usually 
  along 
  trunk 
  roads, 
  many 
  

   of 
  which 
  are 
  bordered 
  by 
  badly 
  infested 
  woodland. 
  These 
  condi- 
  

   tions 
  afford 
  an 
  excellent 
  opportunity 
  for 
  the 
  young 
  caterpillars 
  to 
  

   spin 
  down 
  from 
  the 
  trees 
  and 
  to 
  be 
  carried 
  away 
  by 
  any 
  moving 
  

   object 
  with 
  which 
  they 
  come 
  in 
  contact. 
  Cases 
  are 
  on 
  record 
  where 
  

   city 
  residents 
  who 
  own 
  country 
  or 
  seashore 
  places 
  have 
  caused 
  them 
  

   to 
  become 
  infested 
  by 
  journeying 
  back 
  and 
  forth 
  by 
  automobile. 
  So 
  

   many 
  cases 
  of 
  this 
  kind 
  have 
  been 
  found 
  that 
  it 
  is 
  now 
  considered 
  

   one 
  of 
  the 
  easiest 
  means 
  by 
  which 
  the 
  insect 
  is 
  spread. 
  Automobile 
  

   traffic 
  is 
  very 
  heavy 
  in 
  June, 
  when 
  the 
  gipsy 
  moth 
  is 
  most 
  likely 
  to 
  

   be 
  carried 
  in 
  the 
  caterpillar 
  stage. 
  

  

  OTHER 
  MEANS 
  OF 
  DISPERSING 
  THE 
  GIPSY 
  MOTH. 
  

  

  Another 
  means 
  by 
  which 
  the 
  gipsy 
  moth 
  is 
  dispersed 
  to 
  outlying 
  

   regions 
  is 
  through 
  the 
  unintentional 
  carriage 
  of 
  caterpillars 
  or 
  egg 
  

   clusters 
  by 
  visitors 
  or 
  travelers. 
  In 
  190G 
  this 
  insect 
  was 
  found 
  in 
  

   small 
  numbers 
  on 
  the 
  grounds 
  of 
  the 
  National 
  Soldiers' 
  Home 
  at 
  

   Togus, 
  Me. 
  The 
  nearest 
  known 
  infestation 
  at 
  that 
  time 
  was 
  81 
  miles 
  

   away, 
  and, 
  from 
  the 
  condition 
  of 
  the 
  infestation 
  and 
  the 
  circum- 
  

   stances 
  connected 
  with 
  it, 
  it 
  seemed 
  probable 
  that 
  the 
  insect 
  had 
  been 
  

   brought 
  there 
  either 
  in 
  the 
  egg 
  or 
  caterpillar 
  stage 
  on 
  the 
  clothing 
  

   or 
  among 
  the 
  effects 
  of 
  some 
  of 
  the 
  inmates 
  or 
  visitors 
  who 
  came 
  

   from 
  the 
  infested 
  area 
  in 
  Massachusetts. 
  Isolated 
  infestations 
  are 
  

   continually 
  being 
  found 
  in 
  towns 
  some 
  distance 
  from 
  the 
  infested 
  

   area, 
  especially 
  on 
  farms 
  or 
  in 
  camps 
  where 
  parties 
  from 
  Boston 
  and 
  

   vicinity 
  spend 
  their 
  summer 
  vacations.
