  ami 
  had 
  remained 
  in 
  i)lace 
  since 
  May 
  2Sth. 
  Two 
  clubs 
  of 
  conidial 
  

   spores 
  were 
  borne 
  by 
  this 
  single 
  scale. 
  July 
  6th, 
  conditions 
  as 
  to 
  fungous 
  

   infection 
  the 
  same 
  as 
  on 
  Mr. 
  Temple's 
  place, 
  already 
  reported. 
  Sept. 
  

   2d, 
  Splucrostilbe 
  growing 
  well 
  in 
  this 
  orchard. 
  Nov.

  To-day 
  

   placed 
  cloths 
  for 
  the

  Farm 
  of 
  John 
  Robinson. 
  — 
  June 
  17th, 
  a 
  single 
  tree 
  infected 
  by 
  

   smearing 
  on 
  conidial 
  spores 
  of 
  Spliwrostilbc 
  in 
  a 
  thick 
  paste 
  made 
  from 
  

   culture 
  on 
  corn-meal 
  and 
  broth. 
  Kept 
  moist 
  forty-eight 
  hours 
  with 
  wet 
  

   cloths. 
  July 
  5th, 
  very 
  few 
  scales 
  dead 
  from 
  fungous 
  infection. 
  Disease 
  

   has 
  not 
  spread 
  far. 
  No 
  spore 
  masses 
  observed. 
  Sep't. 
  4th, 
  growth 
  very 
  

   profuse; 
  spread 
  from 
  source 
  of 
  infection 
  in 
  various 
  directions 
  from 
  two 
  

   to 
  four 
  feet. 
  

  

  Another 
  tree 
  infected 
  by 
  tying 
  on 
  pieces 
  of 
  fresh 
  fruiting 
  culture 
  

   grown 
  on 
  corn-meal 
  and 
  broth. 
  June 
  20th, 
  this 
  infection 
  material 
  

   riddled 
  by 
  ants, 
  but 
  fungus 
  growth 
  not 
  eaten. 
  July 
  5th, 
  slight 
  start 
  of 
  

   fungus 
  near 
  point 
  of 
  infection. 
  Bears 
  immature 
  conidial 
  spores. 
  Sept. 
  

   I 
  St, 
  growth 
  very 
  profuse, 
  extending 
  downward 
  over 
  six 
  feet 
  and 
  upward 
  

   sixteen 
  inches. 
  In 
  one 
  place 
  spores 
  had 
  been 
  carried 
  across 
  an 
  air 
  

   space 
  of 
  three 
  feet 
  — 
  probably 
  by 
  birds, 
  insects, 
  or 
  rain. 
  Culture 
  

   material 
  originally 
  applied 
  to 
  the 
  tree 
  still 
  growing 
  in 
  good 
  condition. 
  

   This 
  is 
  the 
  most 
  successful 
  infection 
  experiment 
  I 
  have 
  seen, 
  the 
  growth 
  

   probably 
  being 
  the 
  most 
  profuse 
  because 
  of 
  an 
  abundant 
  and 
  constant 
  

   supply 
  of 
  conidial 
  spores 
  continuously 
  developed 
  from 
  the 
  original 
  

   infection 
  material.

  Farm 
  of 
  James 
  Newcomc. 
  — 
  June 
  23, 
  1898, 
  the 
  San 
  Jose 
  scale 
  

   on 
  thirty 
  trees 
  was 
  infected 
  in 
  this 
  orchard 
  with 
  material 
  grown 
  on 
  

   meal 
  and 
  broth, 
  applied 
  directly 
  from 
  the 
  culture 
  flask 
  without 
  

   ever 
  having 
  been 
  dry. 
  The 
  conidial 
  spores 
  had 
  been 
  mature 
  for 
  about 
  

   two 
  weeks. 
  The 
  gummy 
  mass 
  of 
  the 
  culture 
  was 
  simply 
  smeared 
  upon 
  

   the 
  tree 
  with 
  a 
  little 
  water, 
  and 
  the 
  branch 
  treated 
  was 
  wrapped 
  with 
  

   canvas 
  which 
  was 
  allowed 
  to 
  remain 
  upon 
  the 
  trees 
  for 
  three 
  weeks. 
  

   The 
  trees 
  treated 
  were 
  not 
  very 
  badly 
  infested, 
  and 
  were 
  scattered 
  here 
  

   and 
  there 
  through 
  a 
  large 
  orchard. 
  There 
  was 
  consecpiently 
  little 
  

   o])portunity 
  for 
  the 
  fungus 
  to 
  spread 
  from 
  tree 
  to 
  tree. 
  

  

  July 
  13th, 
  when 
  the 
  first 
  inspection 
  was 
  made, 
  the 
  fungus 
  had 
  

   started 
  in 
  every 
  place, 
  and 
  it 
  had 
  already 
  formed 
  conidial 
  knobs 
  in 
  

   several 
  places, 
  although 
  generally 
  its 
  occurrence 
  was 
  made 
  evident 
  only 
  

   by 
  a 
  white 
  mycelial 
  growth 
  around 
  the 
  edge 
  of 
  the 
  infected 
  scales. 
  

  

  August 
  31st, 
  a 
  careful 
  inspection 
  of 
  a 
  number 
  of 
  trees 
  selected 
  at 
  

   random 
  was 
  made. 
  On 
  the 
  first 
  tree 
  examined 
  the 
  infection 
  was 
  prac- 
  

   tically 
  complete 
  where 
  the 
  surface 
  had 
  been 
  covered 
  by 
  a 
  cloth 
  band.
