  insect 
  is 
  not 
  sufficiently 
  destructive 
  to 
  warrant 
  adopting 
  such 
  

   measures. 
  

  

  Elm 
  leaf 
  beetle 
  (Galerucella 
  luteola 
  Mull.) 
  . 
  This 
  im- 
  

   ported 
  species 
  continues 
  to 
  be 
  a 
  serious 
  pest 
  of 
  elms, 
  particularly 
  

   in 
  the 
  Hudson 
  valley, 
  many 
  of 
  the 
  elms 
  of 
  Yonkers, 
  Poughkeepsie, 
  

   Hudson, 
  Albany, 
  Troy, 
  Schenectady, 
  Schuylerville 
  and 
  Ithaca 
  and 
  

   probably 
  other 
  localities 
  in 
  the 
  State 
  being 
  very 
  badly 
  injured. 
  The 
  

   work 
  at 
  Schuylerville 
  and 
  Schenectady 
  was 
  exceptionally 
  severe 
  and 
  

   the 
  same 
  is 
  also 
  true 
  of 
  its 
  operations 
  at 
  Ithaca. 
  The 
  major 
  part 
  of 
  

   the 
  injury 
  in 
  Albany 
  at 
  least 
  was 
  due 
  to 
  delay 
  in 
  appointing 
  a 
  city 
  

   forester 
  and 
  getting 
  the 
  spray 
  apparatus 
  into 
  operation. 
  Further- 
  

   more, 
  it 
  is 
  very 
  difficult 
  to 
  secure 
  men 
  who 
  can 
  be 
  relied 
  upon 
  to 
  

   do 
  thorough 
  work. 
  Experience 
  has 
  demonstrated 
  beyond 
  all 
  ques- 
  

   tion 
  the 
  practicability 
  of 
  keeping 
  the 
  elm 
  foliage 
  practically 
  intact, 
  

   even 
  in 
  localities 
  where 
  the 
  pest 
  is 
  very 
  abundant. 
  It 
  is 
  for 
  public 
  

   spirited 
  citizens 
  in 
  affected 
  localities 
  to 
  insist 
  upon 
  the 
  maintenance 
  

   of 
  such 
  a 
  standard. 
  

  

  The 
  observations 
  of 
  the 
  past 
  season 
  show 
  in 
  a 
  most 
  striking 
  

   m^anner 
  the 
  extremely 
  local 
  character 
  of 
  this 
  pest. 
  The 
  badly 
  in- 
  

   fested 
  area 
  in 
  Albany 
  has 
  been 
  restricted 
  for 
  the 
  past 
  decade 
  to 
  the 
  

   older 
  and 
  more 
  thickly 
  settled 
  fourth 
  of 
  the 
  city. 
  A 
  study 
  of 
  con- 
  

   ditions 
  in 
  Schenectady 
  showed 
  a 
  similar 
  restriction, 
  the 
  destructive 
  

   work 
  of 
  the 
  pest 
  being 
  limited 
  almost 
  exclusively 
  to 
  a 
  small 
  section 
  

   of 
  the 
  older 
  part 
  of 
  the 
  city, 
  in 
  the 
  vicinity 
  of 
  Church 
  street 
  and 
  

   not 
  extending 
  in 
  any 
  direction 
  more 
  than 
  lo 
  blocks 
  from 
  the 
  center 
  

   of 
  the 
  infestation. 
  Furthermore, 
  the 
  most 
  severe 
  injury 
  was 
  

   noticed 
  upon 
  a 
  group 
  of 
  elms 
  near 
  the 
  open 
  belfry 
  of 
  a 
  church, 
  

   clearly 
  indicating 
  that 
  the 
  insects 
  winter 
  most 
  successfully 
  where 
  a 
  

   structure 
  of 
  this 
  kind 
  affords 
  abundant 
  shelter. 
  

  

  Bag 
  worm 
  (Thyridopteryx 
  ephemeraeformis 
  

   Haw.). 
  New 
  York 
  city 
  and 
  its 
  vicinity 
  represents 
  about 
  the 
  north- 
  

   ern 
  extension 
  of 
  this 
  species, 
  as 
  a 
  rule. 
  It 
  was 
  somewhat 
  surprising, 
  

   therefore, 
  to 
  receive 
  healthy 
  larvae 
  from 
  Germantown, 
  only 
  about 
  

   40 
  miles 
  south 
  of 
  Albany. 
  Mr 
  T. 
  F. 
  Niles, 
  who 
  sent 
  in 
  the 
  speci- 
  

   mens, 
  states 
  that 
  no 
  young 
  trees 
  have 
  been 
  set 
  in 
  this 
  locality 
  within 
  

   the 
  past 
  2 
  years 
  nearer 
  than 
  a 
  quarter 
  of 
  a 
  mile, 
  consequently 
  it 
  

   would 
  seem 
  as 
  though 
  the 
  species 
  was 
  able 
  under 
  certain 
  conditions 
  

   to 
  maintain 
  itself 
  considerably 
  farther 
  north 
  than 
  has 
  heretofore 
  

   been 
  supposed 
  possible. 
  

  

  Fall 
  webworm 
  (Hyphantria 
  textor 
  Harr.) 
  . 
  This 
  com-

  has

  abundant 
  in 
  some 
  portions
