  and 
  buds 
  from 
  these 
  trees 
  have 
  been 
  used 
  in 
  the 
  propagation 
  of 
  nursery 
  

   trees, 
  and 
  already 
  a 
  few 
  trees 
  have 
  been 
  disseminated. 
  Several 
  nurser- 
  

   ies 
  are 
  now 
  propagating 
  these 
  varieties 
  but 
  all 
  combined 
  their 
  output 
  

   will 
  necessarily 
  be 
  very 
  limited 
  for 
  some 
  years 
  to 
  come. 
  

  

  Somewhat 
  in 
  advance 
  of 
  the 
  steps 
  taken 
  in 
  Indiana 
  two 
  varieties, 
  

   the 
  Mantura 
  and 
  the 
  Appomattox, 
  have 
  been 
  introduced 
  from 
  south- 
  

   eastern 
  Virginia 
  by 
  Mr. 
  W. 
  N. 
  Roper 
  of 
  Petersburg. 
  

  

  The 
  Mantura 
  pecan 
  is 
  distinctly 
  of 
  the 
  southern 
  type,— 
  large, 
  thin 
  

   shelled 
  and 
  a 
  ready 
  cracker. 
  It 
  has 
  been 
  disseminated 
  throughout 
  the 
  

   North 
  to 
  some 
  extent 
  when 
  grafted 
  upon 
  the 
  stocks 
  of 
  southern 
  seed- 
  

   lings. 
  None 
  of 
  the 
  trees 
  are 
  yet 
  in 
  bearing. 
  It 
  is 
  now 
  being 
  propagated 
  

   by 
  grafting 
  to 
  stocks 
  of 
  northern 
  seedlings 
  and 
  it 
  is 
  highly 
  probable 
  

   more 
  hardy 
  trees 
  will 
  be 
  the 
  result. 
  

  

  The 
  Appomattox 
  pecan 
  has 
  not 
  yet 
  been 
  propagated 
  to 
  great 
  ex- 
  

   tent. 
  Since 
  the 
  variety 
  was 
  called 
  to 
  public 
  attention, 
  a 
  horse 
  stable 
  

   has 
  been 
  erected 
  immediately 
  under 
  the 
  tree 
  ; 
  and 
  consequently, 
  being 
  

   greatly 
  over-supplied 
  with 
  nitrogen, 
  it 
  has 
  been 
  unable 
  to 
  normally 
  de- 
  

   velop 
  its 
  crops. 
  Good 
  specimens, 
  therefore, 
  have 
  not 
  been 
  obtainable 
  for 
  

   description 
  during 
  the 
  past 
  several 
  years. 
  

  

  In 
  the 
  mind 
  of 
  the 
  introducer, 
  however, 
  it 
  is 
  a 
  valuable 
  variety, 
  

   and 
  well 
  worthy 
  of 
  further 
  observation. 
  

  

  THE 
  SHELLBARK 
  HICKORY 
  {Hicoria 
  laciiiiosa) 
  . 
  

  

  The 
  shellbark 
  hickory 
  is 
  much 
  less 
  common 
  and 
  far 
  less 
  well 
  known 
  

   than 
  is 
  the 
  shagbark. 
  In 
  its 
  native 
  range 
  it 
  appears 
  in 
  certain 
  counties 
  

   of 
  central 
  New 
  York, 
  eastern 
  Pennsylvania 
  and 
  in 
  parts 
  of 
  Ohio, 
  In- 
  

   diana, 
  Illinois, 
  Michigan, 
  Wisconsin, 
  Minnesota, 
  Iowa, 
  Nebraska 
  and 
  

   Oklahoma. 
  According 
  to 
  Nut 
  Culture 
  in 
  the 
  United 
  States,* 
  this 
  spe- 
  

   cies 
  attains 
  its 
  "greatest 
  development 
  along 
  the 
  streams 
  of 
  southern 
  

   Kansas 
  and 
  Missouri, 
  Arkansas 
  and 
  Oklahoma." 
  

  

  The 
  nuts 
  of 
  this 
  species 
  are 
  considerably 
  larger 
  than 
  those 
  of 
  the 
  

   shagbark 
  and 
  of 
  much 
  thicker 
  shell, 
  and 
  commonly 
  do 
  not 
  have 
  as 
  

   plvimp 
  kernels. 
  Exceedingly 
  few 
  have 
  been 
  propagated. 
  

  

  THE 
  AMERICAN 
  HAZELS 
  {Covylus 
  Americana; 
  Corylus 
  rostrata). 
  

  

  Shrubs 
  of 
  these 
  two 
  species 
  are 
  often 
  seen 
  growing 
  together 
  

   throughout 
  the 
  greater 
  portion 
  of 
  the 
  area 
  under 
  discussion. 
  The 
  for- 
  

   mer 
  (C. 
  americana) 
  is 
  of 
  somewhat 
  the 
  better 
  quality. 
  Neither 
  has 
  

   I)een 
  propagated 
  asexually 
  or 
  cultivated 
  to 
  any 
  extent, 
  but 
  it 
  is 
  doubt- 
  

   ful 
  if. 
  any 
  native 
  species 
  of 
  the 
  nut 
  tree 
  offers 
  a 
  more 
  inviting 
  field 
  for 
  

   improvement 
  than 
  do 
  these 
  two 
  species 
  of 
  hazels.
