﻿Fourth 
  report

  The 
  operations 
  of 
  the 
  grape 
  root 
  worm 
  in 
  the 
  Chautauqua 
  region 
  

   have 
  been 
  observed 
  during 
  the 
  season 
  and, 
  in 
  our 
  judgment, 
  there 
  is 
  

   a 
  marked 
  improvement 
  over 
  the 
  conditions 
  of 
  earlier 
  years. 
  This 
  

   change 
  is 
  partly 
  due 
  to 
  the 
  higher 
  price 
  of 
  grapes 
  and 
  the 
  conse- 
  

   quent 
  better 
  care 
  and 
  fertilization 
  given 
  the 
  vineyards, 
  though 
  it 
  is 
  

   .probable 
  that 
  natural 
  conditions 
  have 
  been 
  of 
  material 
  service 
  in 
  

   reducing 
  the 
  numbers 
  of 
  this 
  pest. 
  It 
  is 
  still 
  true 
  that 
  this 
  enemy 
  

   is 
  abundant 
  in 
  limited 
  areas, 
  and 
  danger 
  of 
  serious 
  injury 
  to 
  vine- 
  

   yards 
  here 
  and 
  there 
  is 
  by 
  no 
  means 
  past. 
  

  

  Shade 
  tree 
  protection. 
  Continued 
  devastations 
  by 
  several 
  shade 
  

   tree 
  pests 
  have 
  necessitated 
  the 
  giving 
  of 
  considerable 
  attention 
  to 
  

   this 
  phase 
  of 
  economic 
  entomology. 
  A 
  bulletin 
  on 
  the 
  white 
  

   marked 
  tussock 
  moth 
  and 
  the 
  elm 
  leaf 
  beetle, 
  our 
  two 
  most 
  injurious 
  

   species, 
  was 
  issued 
  in 
  May 
  and 
  a 
  number 
  of 
  warning 
  articles 
  sent 
  

   to 
  the 
  press 
  throughout 
  the 
  State. 
  The 
  general 
  result 
  has 
  been 
  

   highly 
  beneficial 
  and 
  much 
  interest 
  has 
  been 
  aroused. 
  The 
  agitation 
  

   of 
  earlier 
  years 
  secured 
  the 
  appointment 
  of 
  a 
  forester 
  by 
  the 
  city 
  

   of 
  Albany. 
  This 
  official 
  was 
  placed- 
  in 
  charge 
  of 
  the 
  trees, 
  and 
  the 
  

   spraying 
  with 
  poison 
  resulted 
  in 
  marked 
  benefit, 
  despite 
  the 
  

   hindrances 
  incident 
  to 
  work 
  of 
  that 
  character. 
  The 
  city 
  of 
  Troy, 
  

   through 
  municipal 
  agencies, 
  accomplished 
  considerable 
  along 
  this 
  

   line. 
  Before 
  very 
  long 
  a 
  number 
  of 
  other 
  cities 
  will 
  be 
  compelled, 
  by 
  

   the 
  severity 
  of 
  insect 
  depredations, 
  to 
  adopt 
  some 
  protective 
  meas- 
  

   ures 
  or 
  lose 
  many 
  valuable 
  trees. 
  The 
  experience 
  of 
  the 
  last 
  decade 
  

   has 
  demonstrated 
  beyond 
  all 
  question 
  the 
  possibility 
  of 
  protecting 
  our 
  

   trees 
  from 
  injuries 
  by 
  such 
  leaf 
  feeders 
  as 
  the 
  elm 
  leaf 
  beetle 
  and 
  

   the 
  white 
  marked 
  tussock 
  moth. 
  It 
  is 
  practical 
  to 
  spray 
  the 
  trees 
  

   so 
  thoroughly 
  that 
  even 
  in 
  localities 
  where 
  the 
  elm 
  leaf 
  beetle 
  and 
  

   the 
  tussock 
  moth 
  caterpillars 
  are 
  rather 
  abundant, 
  there 
  will 
  be 
  no 
  

   serioua 
  injury 
  to 
  the 
  foliage, 
  and 
  those 
  interested 
  in 
  this 
  work 
  should 
  

   insist 
  upon 
  the 
  maintenance 
  of 
  such 
  a 
  standard. 
  

  

  Gipsy 
  and 
  brown 
  tail 
  moths. 
  The 
  work 
  of 
  last 
  year 
  in 
  watch- 
  

   ing 
  for 
  the 
  appearance 
  of 
  these 
  insects 
  within 
  the 
  borders 
  of 
  New 
  

   York 
  State, 
  has 
  been 
  continued. 
  Many 
  caterpillars 
  of 
  various 
  

   species, 
  all 
  native, 
  however, 
  have 
  been 
  sent 
  in 
  by 
  different 
  corre- 
  

   spondents, 
  some 
  fearing 
  that 
  they 
  had 
  found 
  one 
  or 
  the 
  other 
  of 
  

   these 
  pests. 
  These 
  fears, 
  we 
  are 
  pleased 
  to 
  state, 
  were 
  groundless 
  

   and, 
  so 
  far 
  as 
  known 
  to 
  us 
  at 
  the 
  present 
  time, 
  neither 
  of 
  these 
  

   species 
  has 
  obtained 
  a 
  foothold 
  within 
  our 
  boundaries. 
  

  

  Several 
  days 
  in 
  June 
  were 
  spent 
  in 
  the 
  New 
  England 
  territory 
  

   infested 
  by 
  these 
  species, 
  investigating 
  in 
  particular 
  the 
  recently
