  lu 
  protected 
  places 
  which 
  tlie 
  rains 
  could 
  not 
  reach, 
  the 
  

   dead 
  scales 
  could 
  still 
  be 
  picked 
  oflp 
  several 
  layers 
  deep. 
  Mr. 
  Kiem 
  

   reported 
  that 
  in 
  the 
  early 
  part 
  of 
  the 
  spring 
  a 
  handful 
  of 
  them 
  could 
  

   be 
  got 
  in 
  a 
  short 
  time 
  by 
  scratching 
  the 
  bark 
  with 
  the 
  finger 
  nail. 
  

   This 
  tree 
  had 
  been 
  sprayed 
  five 
  times, 
  while 
  the 
  other 
  trees 
  were 
  

   sprayed 
  but 
  twice. 
  A 
  few 
  living 
  scales 
  were 
  still 
  to 
  be 
  found 
  on 
  the 
  

   trunk 
  and 
  limbs, 
  a 
  part 
  of 
  them 
  in 
  holes 
  or 
  crevices 
  of 
  the 
  bark, 
  and 
  

   others 
  on 
  the 
  smooth 
  surface 
  of 
  the 
  limbs. 
  In 
  picking 
  oft' 
  the 
  

   masses 
  of 
  dead 
  scales 
  packed 
  into 
  crevices 
  in 
  the 
  bark, 
  sometimes 
  

   one, 
  and 
  occasionally 
  two 
  living 
  scales 
  were 
  found 
  at 
  the 
  bottom 
  of 
  

   the 
  mass, 
  but 
  in 
  most 
  cases 
  every 
  one 
  was 
  killed. 
  The 
  eft'ect 
  of 
  the 
  

   treatment 
  in 
  permitting 
  the 
  revival 
  of 
  this 
  originally 
  thrifty 
  tree 
  

   was 
  very 
  conspicuous. 
  The 
  old 
  bark 
  had 
  been 
  generally 
  killed, 
  but 
  

   the 
  tree 
  had 
  made 
  a 
  fine 
  growth 
  this 
  summer, 
  cracking 
  the 
  dead 
  bark, 
  

   which 
  was 
  beginning 
  to 
  peel 
  oft', 
  leaving 
  a 
  young 
  clean 
  bark 
  l)eneath. 
  

   This 
  condition 
  of 
  things 
  was 
  also 
  noticed 
  on 
  other 
  apple-trees, 
  wher- 
  

   ever 
  the 
  scales 
  had 
  been 
  very 
  abundant. 
  

  

  It 
  is 
  thus 
  made 
  evident 
  that 
  an 
  originally 
  healthy 
  tree, 
  in 
  the 
  com- 
  

   plete 
  possession 
  of 
  the 
  scale, 
  may 
  sometimes 
  be 
  saved 
  by 
  a 
  destruc- 
  

   tion 
  of 
  the 
  insects 
  themselves. 
  If 
  the 
  surface 
  of 
  the 
  trunk 
  and 
  

   larger 
  branches 
  of 
  this 
  tree 
  had 
  been 
  scraped 
  and 
  brushed 
  to 
  remove 
  

   the 
  incrusting 
  scales 
  and 
  the 
  rough 
  dead 
  bark 
  before 
  spraying 
  with 
  

   whale-oil 
  soajD, 
  it 
  is 
  (|uite 
  probable 
  that 
  not 
  a 
  single 
  scale 
  would 
  have 
  

   survived. 
  

  

  A 
  large 
  peach-tree, 
  six 
  years 
  old, 
  the 
  worst 
  infested 
  of 
  those 
  left 
  

   standing, 
  and 
  still 
  thickly 
  coated 
  with 
  the 
  dead 
  scales 
  on 
  the 
  trunk 
  

   and 
  larger 
  limbs, 
  was 
  also 
  thoroughly 
  examined. 
  No 
  living 
  scales 
  

   were 
  found 
  on 
  the 
  trunk 
  or 
  on 
  the 
  larger 
  limbs 
  near 
  their 
  origin, 
  but 
  

   a 
  considerable 
  number 
  were 
  seen 
  on 
  both 
  the 
  upper 
  and 
  under 
  sur- 
  

   faces 
  of 
  the 
  smooth 
  bark 
  of 
  the 
  limbs 
  in 
  the 
  middle 
  of 
  the 
  tree. 
  

   According 
  to 
  Mr. 
  Blair's 
  report 
  this 
  tree 
  was 
  less 
  thoroughly 
  sprayed 
  

   than 
  many 
  because 
  of 
  the 
  large 
  amount 
  of 
  fine 
  brush 
  in 
  the 
  top, 
  

   which 
  made 
  it 
  very 
  difficult 
  to 
  distribute 
  the 
  spray 
  to 
  all 
  parts 
  of 
  the 
  

   tree. 
  This 
  difficulty 
  would 
  have 
  been 
  removed 
  if 
  the 
  tree 
  had 
  been 
  

   vigorously 
  trimmed 
  before 
  spraying. 
  Although 
  badly 
  infested 
  with 
  

   borers, 
  it 
  had 
  made 
  a 
  very 
  good 
  growtli 
  during 
  the 
  season, 
  like 
  most 
  

   of 
  the 
  other 
  i:)each-trees 
  treated. 
  

  

  Two 
  or 
  three 
  living 
  scales 
  were 
  found 
  on 
  the 
  trunk 
  of 
  another 
  ap- 
  

   ple-tree, 
  the 
  bark 
  of 
  which 
  was 
  rough 
  and 
  peeling 
  oft' 
  in 
  patches. 
  

   It 
  had 
  not 
  been 
  very 
  badly 
  infested, 
  and 
  was 
  now 
  making 
  an 
  

   excellent 
  growth 
  and 
  bearing 
  several 
  sound 
  apples. 
  

  

  Upon 
  the 
  trunk 
  of 
  still 
  another 
  apple-tree, 
  more 
  thickly 
  infested 
  

   and 
  with 
  rougher 
  bark, 
  one 
  or 
  two 
  living 
  scales 
  were 
  found. 
  On 
  

   three 
  other 
  apple-trees, 
  three 
  or 
  four 
  years 
  younger 
  than 
  the 
  fore- 
  

   going, 
  a 
  few 
  living 
  scales 
  remained 
  at 
  the 
  base 
  of 
  the 
  trunk, 
  eicher 
  

   under 
  the 
  protection 
  of 
  the 
  ragged 
  bark 
  or 
  under 
  masses 
  of 
  scales. 
  

   AVhen 
  these 
  trees 
  were 
  sprayed 
  in 
  spring 
  the 
  ground 
  was 
  covered 
  

   with 
  a 
  mulch 
  of 
  manure, 
  about 
  two 
  or 
  three 
  inches 
  deep 
  around 
  the 
  

   trees, 
  which 
  possibly 
  protected 
  the 
  base 
  of 
  the 
  trunk 
  in 
  part 
  from 
  

   the 
  action 
  of 
  the 
  spray. 
  One 
  of 
  these 
  three 
  apple-trees 
  was 
  the
