  NOMENCLATURE 
  OF 
  THE 
  SHELLBARK 
  HICKORIES. 
  

  

  The 
  names 
  "shellbark," 
  "shagbark" 
  and 
  "scalybark" 
  are 
  at 
  present 
  used 
  

   interchangeably 
  by 
  authors 
  for 
  different 
  species 
  of 
  the 
  hickory. 
  It 
  is 
  advised 
  

   that 
  the 
  Association 
  take 
  an 
  arbitrary 
  stand 
  on 
  the 
  nomenclature 
  and 
  state 
  

   our 
  choice 
  of 
  the 
  name 
  "shagbark" 
  for 
  Hicoria 
  ovata, 
  "shellbark" 
  for 
  Hicoria 
  

   laciniosa 
  and 
  "scalybaric" 
  for 
  Hicoria 
  Carolinae-septentrionalis. 
  

  

  This 
  should 
  become 
  a 
  matter 
  of 
  official 
  record 
  and 
  eventually 
  clear 
  up 
  the 
  

   confusion.

  DYING 
  HICKORY 
  TREES. 
  

  

  Numerous 
  magnificent 
  hickories 
  have 
  been 
  killed 
  by 
  the 
  pernicious 
  hickory 
  bark 
  

   borer 
  in 
  the 
  vicinity 
  of 
  New 
  York 
  city. 
  It 
  has 
  destroyed 
  thousands 
  of 
  trees 
  in 
  the 
  

   central 
  part 
  of 
  the 
  State, 
  while 
  recent 
  investigations 
  show 
  that 
  it 
  is 
  at 
  work 
  in 
  tlie 
  

   Hudson 
  valley 
  near 
  Tivoli 
  and 
  probably 
  is 
  injurious 
  in 
  numerous 
  other 
  places. 
  The 
  

   severe 
  droughts 
  of 
  tlie 
  last 
  two 
  or 
  three 
  years 
  have 
  undoubtedly 
  been 
  favorable 
  to 
  

   the 
  development 
  of 
  this 
  pest, 
  since 
  the 
  vitality 
  of 
  many 
  trees 
  has 
  been 
  lowered 
  and 
  

   they 
  have 
  thus 
  been 
  rendered 
  more 
  susceptible 
  to 
  attack 
  by 
  insect 
  enemie.s. 
  

  

  The 
  preliminary 
  signs 
  of 
  injury, 
  such 
  as 
  wilting 
  leaves 
  and 
  dead 
  twigs 
  in 
  mid- 
  

   summer 
  are 
  exceedingly 
  important 
  because 
  they 
  indicate 
  serious 
  trouble 
  before 
  it 
  

   has 
  passed 
  the 
  remedial 
  stage. 
  Examination 
  of 
  injured 
  trees 
  at 
  the 
  present 
  time 
  

   may 
  show 
  particles 
  of 
  brown 
  or 
  white 
  sawdust 
  in 
  the 
  crevices 
  of 
  the 
  bark, 
  and 
  in 
  

   the 
  case 
  of 
  some 
  a 
  few 
  to 
  many 
  circular 
  holes 
  appearing 
  as 
  though 
  they 
  had 
  been 
  

   made 
  by 
  number 
  8 
  buckshot. 
  This 
  external 
  evidence 
  should 
  be 
  supplemented 
  by 
  

   cutting 
  down 
  to 
  the 
  sapwood. 
  The 
  exposure 
  there 
  of 
  the 
  longitudinal 
  galleries 
  1 
  to 
  

   11,^ 
  inches 
  long, 
  about 
  Vs 
  of 
  an 
  inch 
  in 
  diameter 
  and 
  with 
  numerous 
  fine, 
  transverse 
  

   galleries 
  arising 
  therefi-om 
  and 
  gradually 
  spreading 
  out 
  somewhat 
  fan-shaped, 
  is 
  con- 
  

   clusive 
  evidence 
  as 
  to 
  the 
  identity 
  of 
  this 
  pest. 
  Only 
  a 
  little 
  experience 
  is 
  necessary 
  

   before 
  one 
  can 
  recognize 
  the 
  work 
  of 
  this 
  borer. 
  

  

  The 
  insect 
  passes 
  the 
  winter 
  in 
  oval 
  cells 
  as 
  stout, 
  whitish, 
  brown-headed 
  grubs 
  

   about 
  V4, 
  of 
  an 
  inch 
  long, 
  the 
  beetles 
  appearing 
  from 
  the 
  last 
  of 
  June 
  to 
  the 
  last 
  of 
  

   July. 
  Badly 
  injured 
  trees 
  are 
  beyond 
  hope 
  and 
  should 
  be 
  cut 
  some 
  time 
  during 
  the 
  

   winter 
  and 
  the 
  bark 
  burned 
  before 
  the 
  beetles 
  can 
  emerge 
  ; 
  otherwise 
  many 
  will 
  

   mature 
  and 
  attack 
  other 
  trees 
  next 
  spring. 
  It 
  is 
  particularly 
  important 
  to 
  locate 
  

   the 
  trees 
  which 
  have 
  died 
  wholly 
  or 
  in 
  part 
  the 
  past 
  summer, 
  because 
  they 
  contain
