  Hickory 
  nut 
  weevils 
  destroy 
  many 
  nuts 
  in 
  some 
  localities, 
  and 
  

   their 
  colonies 
  increase- 
  about 
  individual 
  trees 
  markedly. 
  In 
  such 
  cases, 
  

   it 
  is 
  important 
  to 
  collect 
  the 
  entire 
  crop 
  each 
  year 
  from 
  a 
  given 
  tree, 
  

   taking 
  pains 
  to 
  destroy 
  all 
  nuts 
  which 
  contain 
  weevil 
  larvae. 
  These 
  may 
  

   be 
  selected 
  in 
  a 
  general 
  way 
  by 
  dumping 
  the 
  freshly 
  gathered 
  nuts 
  

   into 
  a 
  tub 
  of 
  water. 
  Nuts 
  containing 
  weevil 
  larvae 
  will 
  float 
  for 
  the 
  

   most 
  part, 
  and 
  in 
  order 
  to 
  make 
  sure 
  of 
  the 
  destruction 
  of 
  larvae 
  in 
  the 
  

   remaining 
  nuts 
  they 
  may 
  be 
  placed 
  in 
  a 
  closed 
  receptacle, 
  and 
  carbon 
  

   bisulphide 
  poured 
  over 
  them. 
  

  

  One 
  of 
  the 
  bud 
  worms 
  is 
  sometimes 
  very 
  destructive 
  to 
  individual 
  

   hickory 
  trees 
  which 
  have 
  developed 
  colonies, 
  the 
  larvae 
  destroying 
  the 
  

   axillary 
  buds, 
  and 
  burrowing 
  into 
  the 
  base 
  of 
  the 
  petioles 
  of 
  leaves. 
  

  

  A 
  new 
  enemy 
  which 
  I 
  found 
  this 
  year 
  for 
  the 
  first 
  time 
  is 
  the 
  

   Conotrachelus 
  juglaiidis. 
  This 
  beetle 
  ordinarily 
  lays 
  its 
  eggs 
  in 
  the 
  

   involucre 
  of 
  the 
  butternut. 
  With 
  the 
  introduction 
  of 
  exotic 
  walnuts, 
  

   the 
  beetle 
  has 
  changed 
  its 
  habits, 
  and 
  lays 
  its 
  eggs 
  in 
  the 
  herbaceous 
  

   shoots 
  of 
  walnuts 
  and 
  hickories. 
  The 
  larvae 
  tunnel 
  into 
  the 
  center 
  of 
  

   a 
  shoot, 
  and 
  destroy 
  it, 
  or 
  seriously 
  interfere 
  with 
  its 
  nutrition. 
  

  

  Among 
  the 
  enemies 
  of 
  the 
  hickory 
  we 
  must 
  not 
  forget 
  the 
  common 
  

   field 
  mouse, 
  and 
  the 
  pine 
  mouse, 
  which 
  burrow 
  beneath 
  the 
  surface 
  of 
  

   the 
  ground, 
  and 
  in 
  winter 
  feed 
  freely 
  upon 
  the 
  bark 
  of 
  the 
  roots 
  of 
  the 
  

   hickories. 
  They 
  have 
  destroyed 
  many 
  thousands 
  of 
  young 
  hickories 
  of 
  

   various 
  kinds 
  in 
  my 
  nursery, 
  and 
  in 
  digging 
  up 
  roots 
  of 
  old 
  hickories 
  

   for 
  experimental 
  root 
  grafting 
  I 
  find 
  that 
  mice 
  have 
  been 
  living 
  freely 
  

   for 
  years 
  upon 
  the 
  bark 
  of 
  some 
  roots. 
  

  

  RANDOM 
  NOTES 
  

  

  Aside 
  from 
  the 
  facts 
  which 
  have 
  been 
  grouped 
  together 
  in 
  this 
  

   paper, 
  certain 
  notes 
  may 
  be 
  of 
  interest, 
  as 
  introducing 
  questions 
  for 
  

   speculation. 
  

  

  Are 
  we 
  likely 
  to 
  find 
  more 
  species 
  among 
  the 
  hickories 
  than 
  the 
  

   ones 
  already 
  described? 
  If 
  so 
  well 
  described 
  a 
  species 
  as 
  the 
  H. 
  Buck- 
  

   leyi 
  has 
  almost 
  escaped 
  observation, 
  and 
  if 
  H. 
  Mexicana 
  is 
  confined, 
  as 
  

   it 
  seems 
  to 
  be, 
  to 
  a 
  very 
  limited 
  area, 
  and 
  if 
  most 
  of 
  the 
  hickories 
  grow 
  

   in 
  regions 
  where 
  few 
  botanists 
  are 
  at 
  work, 
  it 
  seems 
  to 
  me 
  prolmble 
  that 
  

   several 
  species 
  remain 
  as 
  yet 
  undiscovered. 
  These 
  are 
  likely 
  to 
  be 
  

   species 
  which 
  lack 
  means 
  of 
  defence, 
  and 
  which 
  are 
  restricted 
  to 
  certain 
  

   small 
  areas. 
  If 
  we 
  make 
  a 
  parallel 
  with 
  other 
  observations 
  of 
  recent 
  

   discoveries, 
  one 
  thinks, 
  for 
  instance, 
  in 
  Ichthyology 
  of 
  the 
  IMarston's 
  

   trout, 
  the 
  Sunapee 
  sabling. 
  Ausable 
  greyling, 
  and 
  the 
  Kern 
  River 
  trout, 
  

   confined 
  almost 
  to 
  a 
  certain 
  stream 
  or 
  lake, 
  and 
  remaining 
  undiscovered 
  

   for 
  years 
  by 
  naturalists, 
  althoitgh 
  familiar 
  to 
  thousands 
  of 
  local 
  fisher- 
  

   men.
