  the 
  dot 
  marking 
  the 
  entrance 
  of 
  the 
  inclosed 
  grub 
  — 
  in 
  short, 
  

   all 
  infested 
  clusters. 
  Or, 
  the 
  clusters 
  might 
  be 
  buried, 
  with 
  a 
  

   foot 
  of 
  solid 
  ground 
  above 
  them, 
  through 
  which, 
  the 
  perfect 
  

   insects 
  if 
  developed 
  under 
  such 
  circumstances, 
  would 
  not 
  be 
  

   able 
  to 
  penetrate. 
  

  

  Regarding 
  so 
  serious 
  an 
  attack 
  upon 
  the 
  grape 
  as 
  of 
  great 
  

   economic 
  importance, 
  and 
  with 
  our 
  knowledge 
  of 
  it 
  limited 
  to 
  

   an 
  experience 
  in 
  a 
  single 
  locality, 
  I 
  deemed 
  it 
  proper 
  to 
  request 
  

   of 
  the 
  gentleman 
  from 
  whom 
  its 
  announcement 
  had 
  been 
  re- 
  

   ceived, 
  a 
  detailed 
  statement 
  for 
  record, 
  of 
  the 
  circumstances 
  

   and 
  conditions 
  attending 
  it, 
  as 
  an 
  aid 
  toward 
  working 
  out 
  the 
  

   life 
  history 
  of 
  a 
  dangerous 
  insect 
  pest, 
  of 
  which 
  so 
  very 
  little 
  

   was 
  known. 
  

  

  He 
  kindly 
  communicated 
  the 
  following 
  statement 
  : 
  

  

  Dear 
  Sir 
  — 
  Your 
  favor 
  of 
  17th 
  November 
  is 
  received. 
  

   Please 
  accept 
  my 
  hearty 
  thanks. 
  I 
  will 
  gladly 
  take 
  pains 
  to 
  

   learn 
  what 
  I 
  can 
  next 
  year 
  about 
  the 
  insect 
  and 
  inform 
  you. 
  

  

  I 
  only 
  have 
  a 
  small 
  place 
  in 
  JMew 
  Jersey, 
  where 
  I 
  live, 
  and 
  

   in 
  my 
  garden 
  I 
  have 
  some 
  twelve 
  or 
  fifteen 
  vines 
  only. 
  The 
  

   place 
  I 
  purchased 
  ^ve 
  years 
  ago, 
  built 
  my 
  house 
  and 
  made 
  

   my 
  garden. 
  The 
  lot 
  was 
  a 
  portion 
  of 
  an 
  old 
  neglected 
  apple 
  

   orchard. 
  The 
  soil 
  is 
  a 
  light 
  sandy 
  loam, 
  with 
  a 
  sub- 
  soil 
  

   of 
  clear 
  sand 
  and 
  gravel, 
  running 
  down 
  probably 
  twenty 
  feet. 
  

   Most 
  of 
  my 
  grape 
  vines 
  are 
  set 
  in 
  a 
  border 
  facing 
  the 
  south- 
  

   west, 
  trained 
  on 
  a 
  post 
  and 
  wire 
  trellis, 
  with 
  Tin 
  ordinary 
  

   picket 
  fence 
  about 
  two 
  feet 
  in 
  the 
  rear 
  — 
  so 
  they 
  have 
  an 
  

   abundance 
  of 
  light 
  and 
  air. 
  

  

  About 
  150 
  feet 
  from 
  this 
  trellis, 
  facing 
  it 
  (hence 
  a 
  north-east 
  

   exposure), 
  is 
  the 
  rear 
  of 
  my 
  house. 
  On 
  a 
  piazza 
  here 
  I 
  have 
  

   a 
  Croton 
  vine, 
  very 
  thrifty, 
  and 
  not 
  far 
  away, 
  against 
  an 
  out- 
  

   house, 
  I 
  have 
  a 
  Catawba, 
  with 
  a 
  south-eastern 
  exposure. 
  

   These 
  two 
  vines 
  bear 
  largely 
  and 
  are 
  the 
  only 
  ones 
  in 
  my 
  

   yard, 
  apparently 
  free 
  from 
  the 
  attack 
  of 
  this 
  insect. 
  

  

  Where 
  I 
  previously 
  lived, 
  I 
  never 
  had 
  any 
  trouble 
  worth 
  

   mentioning 
  with 
  grape 
  enemies, 
  and 
  so 
  was 
  not 
  on 
  the 
  look 
  

   out 
  for 
  this 
  insect. 
  My 
  grapes 
  bore 
  a 
  very 
  little 
  two 
  years 
  

   ago 
  (first 
  crop), 
  and 
  I 
  do 
  not 
  remember 
  any 
  appearance 
  of 
  dis- 
  

   ease. 
  Last 
  year 
  they 
  (or 
  some 
  of 
  them) 
  bore 
  quite 
  a 
  crop, 
  

   and 
  the 
  grapes 
  were 
  badly 
  injured. 
  Gardeners 
  and 
  fruit 
  grow- 
  

   ers 
  in 
  my 
  neighborhood, 
  thought 
  the 
  trouble 
  came 
  from 
  heavy 
  

   and 
  continued 
  rains 
  following 
  a 
  dry 
  spell, 
  the 
  sap 
  starting 
  

   so 
  vigorously 
  as 
  to 
  burst 
  the 
  berry 
  ; 
  I 
  therefore 
  gave 
  the 
  mat- 
  

   ter 
  not 
  much 
  thought. 
  This 
  year, 
  as 
  you 
  know, 
  many 
  of 
  my 
  

   vines 
  fruited 
  largely 
  — 
  notably 
  the 
  Concord, 
  Martha, 
  Walter, 
  

   Croton, 
  Catawba, 
  with 
  a 
  smaller 
  fruitage 
  of 
  Delaware, 
  Hart- 
  

   ford 
  Prolific, 
  etc. 
  With 
  the 
  exception 
  heretofore 
  mentioned,
