  State, 
  its 
  webs 
  on 
  willow 
  in 
  particular 
  forming 
  conspicuous 
  features 
  

   in 
  the 
  landscape. 
  In 
  several 
  instances 
  small 
  wild 
  cherry 
  trees 
  were 
  

   entirely 
  defoliated 
  by 
  this 
  pest. 
  The 
  promiscuous 
  breeding 
  of 
  this 
  

   insect 
  on 
  roadside 
  and 
  other 
  trees, 
  simply 
  increases 
  the 
  danger 
  of 
  

   attack 
  to 
  more 
  valuable 
  trees, 
  particularly 
  when 
  the 
  latter 
  are 
  not 
  

   sprayed 
  systematically. 
  Well 
  cared 
  for 
  and 
  systematically 
  sprayed 
  

   orchards 
  suffer 
  very 
  little 
  from 
  injuries 
  by 
  this 
  species.

  The 
  white 
  marked 
  tussock 
  moth 
  continues 
  

   to 
  be 
  a 
  serious 
  pest 
  on 
  horse-chestnuts 
  and 
  lindens 
  in 
  particular. 
  It 
  

   was 
  extremely 
  abundant 
  and 
  destructive 
  in 
  both 
  Brooklyn 
  and 
  New 
  

   York. 
  It 
  was 
  numerous, 
  though 
  probably 
  not 
  quite 
  so 
  injurious 
  

   in 
  some 
  other 
  localities 
  in 
  the 
  State. 
  The 
  impending 
  destruction 
  in 
  

   Buffalo, 
  we 
  are 
  pleased 
  to 
  state, 
  was 
  greatly 
  mitigated 
  by 
  the 
  

   activity 
  and 
  efficiency 
  of 
  the 
  newly 
  appointed 
  city 
  forester, 
  Mr 
  

   H. 
  B. 
  Filer. 
  Buffalo 
  has 
  long 
  held 
  an 
  unenviable 
  reputation 
  be- 
  

   cause 
  of 
  the 
  poor 
  condition 
  of 
  its 
  shade 
  trees, 
  particularly 
  horse- 
  

   chestnuts, 
  and 
  we 
  trust 
  that 
  the 
  above 
  mentioned 
  appointment 
  

   means 
  a 
  well 
  supported 
  and 
  an 
  advanced 
  policy 
  respecting 
  shade 
  

   tree 
  protection. 
  

  

  The 
  caterpillars 
  of 
  this 
  notorious 
  shade 
  tree 
  pest 
  also 
  occasioned 
  

   considerable 
  anxiety 
  in 
  the 
  fruit 
  section 
  of 
  the 
  western 
  part 
  of 
  the 
  

   State. 
  The 
  partly 
  grown 
  caterpillars 
  were 
  found 
  in 
  considerable 
  

   abundance 
  in 
  orchards, 
  eating 
  into 
  the 
  young 
  fruit, 
  the 
  amount 
  of 
  

   damage 
  being 
  estimated 
  at 
  from 
  lo 
  to 
  80;^. 
  This 
  method 
  

   of 
  injury 
  is 
  by 
  no 
  means 
  unknown, 
  since 
  similar 
  work 
  was 
  ob- 
  

   served 
  in 
  Nova 
  Scotia 
  in 
  the 
  summer 
  of 
  1907. 
  Though 
  it 
  is 
  diffi- 
  

   cult 
  to 
  adequately 
  control 
  caterpillars 
  which 
  have 
  developed 
  the 
  

   fruit-eating 
  habit, 
  it 
  is 
  very 
  easy 
  to 
  keep 
  this 
  pest 
  under 
  control 
  

   in 
  commercial 
  orchards. 
  Systematic 
  spraying 
  with 
  an 
  arsenical 
  

   poison 
  will 
  in 
  the 
  long 
  run, 
  at 
  least, 
  prove 
  most 
  efficacious 
  in 
  de- 
  

   stroying 
  the 
  pest, 
  though 
  it 
  may 
  take 
  a 
  few 
  years 
  to 
  bring 
  about 
  

   these 
  results 
  in 
  badly 
  infested 
  orchards 
  fruiting 
  every 
  season. 
  It 
  

   is 
  comparatively 
  easy 
  to 
  practically 
  clear 
  trees 
  of 
  this 
  insect 
  by 
  

   collecting 
  the 
  conspicuous 
  white 
  egg 
  masses 
  any 
  time 
  during 
  the 
  

   winter. 
  This 
  work 
  can 
  be 
  done 
  thoroughly 
  and 
  at 
  comparatively 
  

   slight 
  expense, 
  then 
  there 
  is 
  no 
  occasion 
  for 
  worry 
  as 
  to 
  the 
  out- 
  

   come 
  another 
  season, 
  and 
  an 
  orchard 
  once 
  cleared 
  is 
  easily 
  kept 
  

   comparatively 
  free 
  from 
  subsequent 
  injury. 
  

  

  Snow-white 
  linden 
  moth 
  (Ennomos 
  subsignarius 
  

   Hubn.), 
  This 
  species, 
  at 
  one 
  time 
  recognized 
  as 
  a 
  most 
  destructive
