  Injuries 
  in 
  Troy 
  and 
  Vicinity. 
  

  

  The 
  neighboring 
  city 
  of 
  Troy, 
  N. 
  Y., 
  six 
  miles 
  northward 
  of 
  Albany, 
  

   was 
  visited 
  August 
  i8th 
  for 
  the 
  purpose 
  of 
  observing 
  the 
  operations 
  of 
  the 
  

   ehii-leaf 
  beetle 
  there 
  and 
  in 
  the 
  vicinity. 
  It 
  was 
  found 
  that 
  the 
  foliage 
  

   of 
  most 
  of 
  the 
  English 
  ehns 
  throughout 
  the 
  city 
  had 
  been 
  completely 
  

   skeletonized 
  by 
  the 
  larvae 
  of 
  the 
  first 
  brood. 
  From 
  the 
  western 
  end 
  of 
  

   Hyland 
  avenue, 
  commanding 
  a 
  view 
  of 
  a 
  large 
  portion 
  of 
  the 
  city, 
  the 
  

   brown, 
  dead 
  leaves 
  could 
  be 
  seen 
  in 
  all 
  directions, 
  and 
  gave 
  the 
  impres- 
  

   sion 
  of 
  an 
  extensive 
  destruction 
  by 
  fire. 
  

  

  A 
  closer 
  examination 
  of 
  the 
  condition 
  of 
  the 
  Enghsh 
  and 
  Scotch 
  elms 
  

   throughout 
  the 
  city, 
  showed 
  that 
  the 
  infestation 
  and 
  consequent 
  damage 
  

   was 
  fully 
  as 
  great 
  as 
  appeared 
  from 
  a 
  general 
  view. 
  The 
  elms 
  every- 
  

   where 
  were 
  seriously 
  injured, 
  and 
  in 
  most 
  instances 
  the 
  first 
  crop 
  of 
  leaves 
  

   had 
  been 
  completely 
  destroyed. 
  It 
  was 
  learned 
  that 
  the 
  insect 
  had 
  been 
  

   in 
  the 
  lower 
  part 
  of 
  the 
  city 
  for 
  years 
  past 
  — 
  at 
  least 
  three. 
  From 
  this 
  it 
  

   would 
  appear 
  that 
  the 
  beetles 
  must 
  have 
  entered 
  Troy 
  in 
  1892, 
  and 
  

   possibly 
  earlier. 
  The 
  city 
  had 
  certainly 
  suffered 
  more 
  from 
  the 
  insect 
  

   the 
  past 
  year 
  than 
  had 
  Albany. 
  

  

  The 
  most 
  badly 
  infested 
  region 
  in 
  Troy 
  was 
  between 
  the 
  Hudson 
  river 
  

   on 
  the 
  East 
  and 
  Fifteenth 
  street 
  on 
  the 
  West, 
  extending 
  from 
  near 
  the 
  

   southern 
  boundary 
  of 
  the 
  city 
  to 
  Hoosick 
  street 
  on 
  the 
  north. 
  The 
  

   southern 
  end 
  of 
  Green 
  Island 
  and, 
  on 
  the 
  western 
  bank 
  of 
  the 
  river, 
  a 
  

   large 
  portion 
  of 
  the 
  city 
  of 
  Watervliet 
  (formerly 
  West 
  Troy), 
  was 
  also 
  

   badly 
  infested. 
  The 
  insect 
  was 
  found 
  in 
  limited 
  numbers 
  on 
  the 
  .high 
  

   lands 
  east 
  of 
  Troy, 
  along 
  Tibbets 
  avenue, 
  at 
  Albia, 
  and 
  at 
  Averill 
  Park 
  

   in 
  the 
  town 
  of 
  Sand 
  Lake, 
  some 
  seven 
  miles 
  southeast 
  of 
  the 
  city. 
  On 
  

   the 
  north 
  and 
  west 
  of 
  Troy, 
  signs 
  of 
  it 
  in 
  limited 
  numbers 
  were 
  seen 
  over 
  

   most 
  of 
  adjoining 
  Lansingburg, 
  and 
  in 
  portions 
  of 
  Cohoes 
  and 
  Water- 
  

   ford 
  on 
  the 
  opposite 
  side 
  of 
  the 
  river. 
  It 
  had 
  become 
  established 
  at 
  

   Menands, 
  half 
  way 
  between 
  Albany 
  and 
  Troy, 
  in 
  considerable 
  numbers. 
  

   It 
  had 
  also 
  been 
  found 
  by 
  Dr. 
  L. 
  O. 
  Howard, 
  Entomologist 
  to 
  the 
  U. 
  S, 
  

   Department 
  of 
  Agriculture, 
  at 
  Mechanicville, 
  about 
  ten 
  miles 
  north 
  of 
  

   Troy. 
  

  

  Associated 
  Insects. 
  

  

  The 
  elm-leaf 
  beetle 
  finds 
  a 
  very 
  efficient 
  ally 
  in 
  its 
  destructive 
  work 
  in 
  

   the 
  European 
  Coccid, 
  Gossyparia 
  ulmi 
  (Geoff.), 
  which 
  is 
  widely 
  dis- 
  

   tributed 
  over 
  Albany, 
  Troy 
  and 
  Watervliet. 
  The 
  insect 
  was 
  so 
  numerous 
  

   on 
  many 
  trees 
  that 
  the 
  leaves 
  and 
  branches 
  were 
  blackened 
  by 
  the 
  fungus 
  

   growing 
  in 
  its 
  abundant 
  secretion 
  to 
  such 
  an 
  extent 
  as 
  to 
  render 
  them 
  

   conspicuous 
  at 
  a 
  distance. 
  Its 
  occurrence 
  in 
  such 
  numbers 
  must 
  weaken
