  every 
  scale 
  showing 
  the 
  reil 
  growth 
  of 
  the 
  fungus, 
  which 
  had 
  also 
  spread 
  

   down 
  the 
  branch 
  about 
  six 
  inches. 
  Scales 
  of 
  all 
  sizes 
  were 
  attacked, 
  

   but 
  there 
  was 
  no 
  apparent 
  spread 
  upward 
  or 
  to 
  the 
  adjacent 
  branches. 
  

   The 
  external 
  growth 
  was 
  most 
  commonly 
  in 
  the 
  form 
  of 
  erect 
  clubs 
  or 
  

   knob-like 
  protuberances, 
  but 
  sometimes 
  in 
  that 
  of 
  a 
  thick 
  welt 
  surround- 
  

   ing 
  the 
  scale. 
  On 
  another 
  tree 
  the 
  fungus 
  had 
  spread 
  very 
  ])rofusely 
  

   along 
  the 
  limb 
  for 
  about 
  thirteen 
  inches. 
  On 
  one, 
  where 
  the 
  scale 
  was 
  

   very 
  scarce, 
  it 
  had 
  spread 
  but 
  three 
  inches; 
  on 
  two 
  others 
  twelve 
  

   inches; 
  and 
  on 
  still 
  another 
  fifteen 
  inches. 
  On 
  the 
  next 
  tree 
  examined 
  

   it 
  had 
  spread 
  two 
  feet 
  on 
  a 
  main 
  branch, 
  and 
  also 
  slightly 
  upon 
  lateral 
  

   twigs. 
  On 
  one 
  tree 
  carefully 
  examined 
  it 
  had 
  grown 
  down 
  a 
  main 
  

   branch 
  for 
  about 
  ten 
  inches 
  from 
  a 
  profusely 
  infected 
  area, 
  and 
  laterally 
  

   from 
  a 
  little 
  below 
  this 
  area 
  about 
  an 
  inch. 
  Here, 
  as 
  elsewhere, 
  the 
  

   fungus 
  was 
  most 
  abundant 
  upon 
  the 
  spots 
  originally 
  treated. 
  Here 
  

   several 
  pieces 
  of 
  paste 
  remained 
  with 
  the 
  fungus 
  fresh 
  and 
  ap]iarently 
  

   still 
  growing. 
  November 
  ist, 
  when 
  the 
  winter 
  bands 
  were 
  put 
  in 
  place, 
  

   there 
  had 
  been 
  little 
  if 
  any 
  extension 
  of 
  the 
  infecteil 
  area, 
  and 
  the 
  growth 
  

   generally 
  seemed 
  to 
  be 
  somewhat 
  less 
  vigorous 
  than 
  on 
  August 
  31st, 
  

   probably 
  because 
  the 
  very 
  heavy 
  rains 
  had 
  washed 
  away 
  the 
  spores.

  During 
  the 
  intervals 
  of 
  other 
  field 
  employment 
  a 
  few 
  minor 
  experi- 
  

   ments 
  with 
  insecticide 
  sprays 
  were 
  made 
  l)y 
  Mr. 
  K. 
  13. 
  Forbes 
  in 
  the 
  

   infested 
  orchards 
  near 
  Sparta, 
  Randolph 
  county, 
  in 
  the 
  montlis 
  of 
  June 
  

   and 
  July. 
  No 
  final 
  conclusions 
  were 
  reached, 
  but 
  as 
  the 
  work 
  was 
  thor- 
  

   oughly 
  and 
  carefully 
  done 
  the 
  results 
  are 
  deemed 
  worthy 
  of 
  repf)rt. 
  

  

  June 
  i/th 
  to 
  20th, 
  ])ure 
  kerosene 
  was 
  applied 
  to 
  fifteen 
  peach-trees, 
  

   sometimes 
  with 
  the 
  "Eclipse" 
  sprayer 
  and 
  "Deming 
  Vermorel" 
  nozzle, 
  

   sometimes 
  with 
  the 
  "Success" 
  sprayer 
  and 
  " 
  Bordeaux 
  " 
  nozzle. 
  The 
  

   results 
  were 
  in 
  every 
  case 
  unsatisfactory. 
  If 
  a]:)[)lied 
  in 
  sufficient 
  (pian- 
  

   tity 
  to 
  kill 
  all 
  the 
  scales 
  the 
  trees 
  were 
  usually 
  so 
  severely 
  injured 
  that 
  

   they 
  were 
  dead 
  by 
  September 
  ist, 
  or 
  if 
  not 
  dead 
  their 
  vigor 
  had 
  been 
  so 
  

   impaired 
  that 
  they 
  had 
  been 
  very 
  heavily 
  attacked 
  by 
  the 
  fruit 
  bark 
  

   beetle 
  {Sct)/r///s 
  nigii/osiis). 
  In 
  one 
  case 
  a 
  peach-tree 
  thu'^ 
  sprayed 
  had 
  

   borne 
  a 
  good 
  crop 
  of 
  fruit 
  and 
  held 
  its 
  leaves 
  without 
  a])parent 
  injury 
  

   until 
  September 
  ist, 
  but 
  its 
  bark 
  was 
  everywhere 
  ]3ep])ered 
  with 
  the 
  

   punctures 
  of 
  the 
  fruit 
  bark 
  beetle, 
  from 
  which 
  particles 
  of 
  gum 
  had 
  

   exuded 
  in 
  such 
  quantity 
  as 
  nearly 
  to 
  cover 
  the 
  surface 
  in 
  many 
  places. 
  

   In 
  but 
  two 
  cases 
  had 
  the 
  trees 
  escaped 
  such 
  injury, 
  and 
  in 
  these 
  only 
  

   the 
  scales 
  exposed 
  to 
  direct 
  contact 
  with 
  the 
  spray 
  were 
  dead, 
  all 
  con- 
  

   cealed 
  or 
  protected 
  in 
  any 
  way 
  remaining 
  alive 
  and 
  producing 
  \ 
  oung 
  

   continuously.
