  There 
  are 
  several 
  records 
  of 
  the 
  occurrence 
  of 
  snakeworms 
  in 
  this 
  

   country, 
  but 
  detailed 
  observations 
  are 
  wanting 
  in 
  most 
  cases, 
  and 
  in 
  none 
  

   has 
  the 
  species 
  been 
  identified 
  to 
  my 
  knowledge.

  two 
  instances 
  in 
  which 
  he 
  

   observed 
  snakeworms 
  after 
  heavy 
  rains, 
  and 
  he 
  is 
  of 
  the 
  opinion 
  that 
  in 
  

   these 
  cases 
  the 
  larvae 
  were 
  driven 
  by 
  water 
  from 
  their 
  usual 
  haunts. 
  

   The 
  larvae, 
  like 
  others 
  known 
  to 
  belong 
  

   to 
  the 
  genus 
  Sciara, 
  are 
  legless, 
  whitish 
  

   and 
  with 
  black 
  heads. 
  The 
  specimens 
  re- 
  

   ceived 
  measured 
  6-7 
  mm 
  long.

  Forest 
  tent-caterpillar 
  (Clisiocampadisstria 
  Hiibn.). 
  The 
  

   depredations 
  of 
  this 
  pest 
  in 
  1898 
  and 
  1899 
  gave 
  rise 
  to 
  well 
  grounded 
  fears 
  

   that 
  it 
  might 
  prove 
  destructive 
  this 
  year. 
  Examinations 
  of 
  sugar 
  maple 
  

   trees 
  during 
  the 
  winter 
  of 
  1899-1900 
  showed 
  that 
  the 
  egg 
  clusters 
  of 
  this 
  

   species 
  were 
  present 
  in 
  large 
  numbers 
  in 
  some 
  localities. 
  The 
  following 
  

   records 
  of 
  these 
  observations 
  give 
  an 
  idea 
  of 
  the 
  conditions 
  prevailing 
  in 
  

   various 
  sections 
  of 
  the 
  state. 
  At 
  Nelson, 
  West 
  Eaton, 
  Stockbridge 
  and 
  

   Hamilton, 
  Madison 
  co., 
  many 
  of 
  the 
  sugar 
  maples 
  were 
  abundantly 
  

   supplied 
  with 
  egg 
  clusters 
  of 
  this 
  pest. 
  At 
  Durham, 
  Greene 
  co., 
  and 
  

   Franklin, 
  Delaware 
  co., 
  egg 
  clusters 
  were 
  present 
  in 
  considerable 
  

   numbers 
  on 
  some 
  maples. 
  One 
  small 
  maple 
  at 
  Durham 
  had 
  at 
  least 
  

   25 
  egg 
  clusters; 
  on 
  one 
  small 
  twig 
  there 
  were 
  eight, 
  four 
  being 
  placed 
  

   end 
  to 
  end. 
  Some 
  badly 
  infested 
  trees 
  were 
  found 
  at 
  Esperance, 
  

   Schenectady 
  co., 
  and 
  at 
  Albany, 
  Altamont 
  and 
  Voorheesville, 
  Albany 
  

   CO. 
  At 
  Greenfield 
  Center 
  and 
  Burnt 
  Hills, 
  Saratoga

  Glens 
  Falls, 
  

   Warren 
  co., 
  and 
  Fort 
  Ann 
  and 
  Cambridge, 
  Washington 
  co., 
  some 
  trees 
  

   were 
  pretty 
  well 
  stocked 
  with 
  eggs. 
  At 
  Hoosick 
  Falls, 
  Rensselaer 
  co., 
  

   a 
  number 
  of 
  maples 
  were 
  badly 
  infested. 
  One 
  small 
  one 
  had 
  50 
  egg
