  *' 
  The 
  whole 
  of 
  the 
  outer 
  bark 
  was 
  removed 
  from 
  the 
  elm 
  (this 
  may 
  be 
  

   done 
  conveniently 
  by 
  a 
  scraping-knife 
  shaped 
  like 
  a 
  spoke-shave). 
  This 
  

   operation 
  caused 
  a 
  great 
  flow 
  of 
  sap 
  in 
  the 
  inner 
  lining 
  of 
  the 
  bark 
  (the 
  

   liber) 
  and 
  the 
  grubs 
  of 
  the 
  Scolytus 
  beetle 
  were 
  found 
  in 
  almost 
  all 
  cases 
  

   to 
  perish 
  shortly 
  after. 
  The 
  treatment 
  was 
  applied 
  on 
  a 
  large 
  scale, 
  and 
  

   the 
  barked 
  trees 
  were 
  found, 
  after 
  examination 
  by 
  the 
  commissioners 
  at 
  

   two 
  different 
  periods, 
  to 
  be 
  in 
  more 
  vigorous 
  health 
  than 
  the 
  neighboring 
  

   ones 
  of 
  which 
  the 
  bark 
  was 
  untouched. 
  More 
  than 
  two 
  thousand 
  elms 
  

   were 
  thus 
  treated." 
  

  

  M. 
  Robert 
  had 
  also 
  obtained 
  good 
  results 
  from 
  cutting 
  out 
  strips 
  of 
  

   the 
  bark 
  of 
  old 
  elms 
  of 
  about 
  two 
  inches 
  wide 
  from 
  the 
  boughs 
  down 
  to 
  

   the 
  ground. 
  " 
  It 
  was 
  found 
  that 
  where 
  the 
  young 
  bark 
  pressed 
  forward 
  

   to 
  heal 
  the 
  wound 
  and 
  a 
  vigorous 
  flow 
  of 
  sap 
  took 
  place, 
  many 
  of 
  the 
  

   larvae 
  near 
  it 
  were 
  killed, 
  — 
  the 
  bark, 
  that 
  had 
  not 
  entirely 
  been 
  under- 
  

   mined 
  was 
  consolidated, 
  and 
  the 
  health 
  of 
  the 
  tree 
  improved."
