  Thirtieth 
  Report

  State 
  Museum.

  all 
  were 
  attacked. 
  I 
  noticed 
  it 
  first 
  as 
  the 
  grapes 
  reached 
  

   their 
  full 
  size, 
  and 
  began 
  to 
  ripen, 
  and 
  I 
  suppose 
  I 
  lost 
  quite 
  

   three 
  quarter's 
  of 
  the 
  fruit 
  on 
  the 
  vines 
  thus 
  attacked. 
  

  

  I 
  do 
  not 
  know 
  how 
  widespread 
  the 
  trouble 
  may 
  be. 
  Some 
  

   of 
  my 
  neighbors 
  have 
  suffered 
  somewhat, 
  but 
  I 
  think 
  none 
  so 
  

   much 
  as 
  I. 
  I 
  propose 
  to 
  take 
  pains 
  .to 
  get 
  the 
  experience 
  of 
  

   the 
  fruit-growers 
  around 
  me, 
  and 
  will 
  then, 
  as 
  you 
  request, 
  

   communicate 
  with 
  you 
  further. 
  

  

  Yours 
  respectfully,

  Notices 
  of 
  "grape-rot," 
  as 
  a 
  serious 
  evil 
  prevalent 
  in 
  various 
  

   parts 
  of 
  the 
  country, 
  have 
  appeared, 
  from 
  time 
  to 
  time, 
  for 
  

   the 
  past 
  few 
  years, 
  in 
  our 
  agricultural 
  journals. 
  Its 
  cause 
  has 
  

   been 
  extensively 
  discussed, 
  many 
  speculations 
  have 
  been 
  ad- 
  

   vanced, 
  earnest 
  study 
  has 
  been 
  given 
  it, 
  but 
  up 
  to 
  the 
  present 
  

   time, 
  its 
  occurrence, 
  like 
  that 
  of 
  the 
  pear-blight, 
  has 
  received 
  

   no 
  satisfactory 
  explanation. 
  

  

  Is 
  it 
  possible 
  that 
  it 
  may 
  be 
  but 
  a 
  phase 
  of 
  a 
  formidable 
  

   Isosoma 
  vitis 
  attack 
  % 
  This 
  question 
  arises, 
  when 
  too 
  late 
  to 
  

   answer 
  it 
  through 
  examinations 
  the 
  present 
  year. 
  It 
  may. 
  be 
  

   that 
  the 
  conjecture, 
  for 
  such 
  it 
  merely 
  is, 
  may 
  at 
  once 
  be 
  dis- 
  

   missed 
  as 
  without 
  foundation, 
  by 
  those 
  conversant 
  with 
  the 
  

   disease 
  (of 
  which 
  the 
  writer 
  only 
  knows 
  the 
  name), 
  and 
  can 
  

   recall 
  in 
  it, 
  conditions 
  inconsistent 
  with 
  those 
  attendant 
  upon 
  

   the 
  insect 
  attack, 
  as 
  above 
  reported. 
  The 
  shriveling 
  of 
  the 
  

   berry, 
  its 
  discoloration 
  (its 
  partial 
  decomposition, 
  perhaps, 
  of 
  

   which 
  no 
  mention 
  has 
  been 
  made), 
  and 
  its 
  dropping 
  to 
  the 
  

   ground, 
  might 
  easily 
  present 
  most 
  of 
  the 
  features 
  of 
  an 
  ordi- 
  

   nary 
  decay. 
  

  

  If 
  the 
  question 
  herewith 
  raised 
  of 
  the 
  identity 
  of 
  the 
  two 
  may 
  

   not 
  be 
  at 
  once 
  authoritatively 
  answered 
  by 
  the 
  grape-grower 
  

   familiar 
  with 
  all 
  the 
  phases 
  of 
  the 
  grape-rot, 
  then 
  it 
  will 
  

   remain 
  as 
  a 
  most 
  interesting 
  subject 
  for 
  determination 
  the 
  com- 
  

   ing 
  season. 
  Should 
  the 
  suspicion 
  be 
  verified, 
  and 
  the 
  cause 
  

   of 
  the 
  wide-spread 
  and 
  growing 
  evil 
  be 
  discovered 
  so 
  singu- 
  

   larly 
  hidden 
  within 
  the 
  seeds, 
  then 
  there 
  is 
  scarce 
  a 
  doubt, 
  but 
  

   that 
  by 
  the 
  sacrifice 
  of 
  one 
  or 
  two 
  crops 
  the 
  progress 
  of 
  the 
  

   evil 
  can 
  be 
  effectually 
  arrested.
