  far 
  enough 
  to

  strong 
  hopes 
  that

  fungus

  will 
  serve 
  as 
  a 
  permanently 
  useful 
  and 
  highly 
  efficient 
  ally 
  

   in 
  the 
  destruction 
  of 
  this

  likely 
  of 
  otiier 
  injurious 
  

   scales

  PKECAUTIONAKY 
  AND 
  REMEDIAL 
  MEASURES. 
  

  

  The 
  obscure 
  character 
  of 
  the 
  San 
  Jose 
  scale 
  and 
  the 
  ditficuity 
  of 
  

   ridding 
  premises 
  of 
  it 
  when 
  once 
  iiifested, 
  make 
  general 
  and 
  precau- 
  

   tionary 
  measures 
  the 
  main 
  reliance 
  against 
  its 
  ravages. 
  The 
  follow- 
  

   ing 
  suggestions 
  are 
  made 
  in 
  a 
  form 
  to 
  apply 
  both 
  to 
  the 
  business 
  of 
  

   the 
  nurseryman 
  and 
  to 
  the 
  protection 
  and 
  disinfection 
  of 
  the 
  prem- 
  

   ises 
  of 
  his 
  customers. 
  

  

  1. 
  Great 
  care 
  should 
  be 
  used 
  in 
  selecting 
  stock. 
  With 
  the 
  num- 
  

   erous 
  possible 
  sources 
  of 
  contamination 
  now 
  scattered 
  throughout 
  

   the 
  country, 
  no 
  fruit 
  grower 
  is 
  really 
  safe 
  who 
  does 
  not 
  first 
  assure 
  

   himself 
  that 
  the 
  premises 
  from 
  which 
  his 
  young 
  stock 
  may 
  be 
  ob- 
  

   tained 
  are 
  themselves 
  free 
  from 
  this 
  insect, 
  and 
  who 
  does 
  not 
  also 
  

   critically 
  inspect 
  every 
  portion 
  of 
  every 
  tree 
  and 
  shrub 
  liable 
  to 
  

   attack 
  by 
  this 
  scale 
  which 
  comes 
  to 
  his 
  premises. 
  The 
  best 
  evidence 
  

   of 
  the 
  absence 
  of 
  the 
  scale 
  from 
  any 
  nursery 
  is 
  the 
  high 
  reputation 
  

   of 
  the 
  nurseryman 
  for 
  care, 
  business 
  method, 
  and 
  scrupulous 
  honesty. 
  

   Stock 
  from 
  such 
  a 
  nurseryman 
  in 
  a 
  district 
  known 
  to 
  have 
  been 
  in- 
  

   fested 
  by 
  the 
  scale 
  in 
  the 
  past, 
  is 
  perhaps 
  a 
  safer 
  investment 
  than 
  

   indiscriminate 
  purchases 
  made 
  from 
  less 
  reliable 
  men 
  in 
  regions 
  

   where 
  this 
  scale 
  has 
  not 
  yet 
  been 
  detected, 
  (yontirmation 
  of 
  this 
  

   view 
  is 
  given 
  by 
  the 
  fact 
  that 
  among 
  the 
  numerous 
  importations 
  

   from 
  eastern 
  nurseries 
  examined 
  by 
  us 
  during 
  the 
  last 
  few 
  months, 
  

   only 
  one 
  importation 
  made 
  <(ffer 
  the 
  (liscorerij 
  of 
  f 
  his 
  scale 
  in 
  those 
  

   nurseries 
  has 
  yet 
  been 
  found 
  infested. 
  

  

  2. 
  A 
  very 
  important 
  additional 
  safeguard 
  is 
  a 
  certiticate 
  of 
  in- 
  

   spection, 
  issued 
  by 
  some 
  official 
  expert, 
  certifying 
  to 
  the 
  freedom 
  of 
  

   the 
  stock 
  in 
  question 
  from 
  injurious 
  insects 
  and 
  fungus 
  diseases. 
  

   The 
  time 
  seems 
  rapidly 
  approaching 
  when 
  official 
  inspection 
  and 
  

   certificates 
  will 
  be 
  a 
  necessity 
  of 
  the 
  trade. 
  Too 
  much 
  reliance 
  

   must 
  not 
  be 
  placed, 
  however, 
  upon 
  the 
  absolute 
  value 
  of 
  an 
  in- 
  

   spector's 
  certificate 
  to 
  the 
  absence 
  of 
  the 
  San 
  Jose 
  scale 
  on 
  an}' 
  

   suspected 
  premises 
  or 
  from 
  any 
  lot 
  of 
  inspected 
  stock. 
  It 
  is 
  a 
  physi- 
  

   cal 
  impossibility 
  to 
  assure 
  one's 
  self 
  beyond 
  all 
  possible 
  doubt 
  that 
  

   not 
  so 
  much 
  as 
  a 
  single 
  fertilized 
  scale 
  is 
  present 
  on 
  even 
  a 
  singk' 
  

   tree, 
  and 
  one 
  such 
  scale, 
  if 
  overlooked, 
  may 
  give 
  rise 
  within 
  a 
  very 
  

   brief 
  time 
  to 
  a 
  destructive 
  colony. 
  Indeed, 
  no 
  critically 
  careful 
  

   inspector 
  will 
  issue 
  unqualified 
  certificates 
  of 
  freedom 
  from 
  injurious 
  

   insects 
  or 
  fungus 
  diseases. 
  It 
  is 
  further 
  to 
  be 
  remembered, 
  that 
  an 
  

   inspection 
  of 
  the 
  premises 
  of 
  a 
  nursery 
  and 
  a 
  certificate 
  of 
  freedom 
  

   from 
  the 
  scale, 
  are 
  not 
  a 
  guarantee 
  of 
  all 
  stock 
  which 
  may 
  be 
  shipped 
  

   out 
  by 
  the 
  owner, 
  since 
  a 
  large 
  percentage 
  of 
  that 
  sold 
  by 
  most 
  

   nurserymen 
  originates 
  elsewhere. 
  The 
  rearing 
  of 
  nursery 
  stock 
  has 
  

   now 
  become 
  largely 
  specialized 
  in 
  localities, 
  to 
  the 
  great 
  advantage, 
  

   indeed, 
  both 
  of 
  the 
  dealer 
  and 
  his 
  customer. 
  The 
  certificate 
  referred 
  

   to 
  should 
  consequently 
  apjjly 
  immediately 
  to 
  the 
  entire 
  lot 
  of 
  stock 
  

   purchased; 
  or, 
  if 
  it 
  is 
  a 
  certificate 
  of 
  inspection 
  of 
  premises 
  only, 
  it
