  Pine 
  forms 
  a 
  little 
  more 
  than 
  50 
  per 
  cent 
  of 
  the 
  total 
  stand, 
  and 
  

   Shortleaf 
  is 
  more 
  than 
  twice 
  as 
  abundant 
  as 
  Loblolly. 
  

  

  In 
  this 
  type 
  of 
  forest 
  the 
  pines, 
  both 
  Shortleaf 
  and 
  Loblolly, 
  occur 
  

   either 
  in 
  very 
  small 
  groups 
  or 
  scattered 
  about 
  by 
  single 
  trees; 
  more 
  

   commonly 
  the 
  latter. 
  They 
  tower 
  high 
  above 
  the 
  crowns 
  of 
  the 
  hard- 
  

   woods, 
  forming 
  a 
  kind 
  of 
  second 
  story 
  over 
  the 
  oaks. 
  gums, 
  hickories, 
  

   etc.. 
  which 
  occur 
  by 
  single 
  trees, 
  quite 
  evenly 
  distributed. 
  Under 
  the 
  

   old 
  hardwoods 
  is 
  a 
  grow 
  th 
  of 
  hardwood 
  saplings 
  and 
  poles, 
  intermixed 
  

   with 
  Shortleaf 
  and 
  Loblollv 
  Pine. 
  This 
  undergrowth 
  is 
  found 
  both 
  in 
  

   large 
  and 
  small 
  groups 
  and 
  scattered 
  openly 
  and 
  irregularly, 
  while 
  

   over 
  large 
  areas 
  it 
  is 
  entirely 
  absent, 
  leaving 
  the 
  ground 
  clear 
  and 
  (tare 
  

   under 
  the 
  mature 
  trees. 
  Shortleaf 
  and 
  Loblollv 
  Pine 
  seedlings 
  are 
  

   exceedingly 
  scarce 
  in 
  this 
  type 
  of 
  forest, 
  owing 
  principally 
  to 
  the 
  

   frequent 
  ground 
  tires, 
  and 
  also 
  to 
  the 
  fact 
  that 
  they 
  will 
  not 
  flourish 
  

   under 
  too 
  great 
  a 
  shade 
  from 
  the 
  hardwoods. 
  

  

  When 
  a 
  forest 
  is 
  lumbered 
  for 
  all 
  merchantable 
  pine 
  down 
  to 
  14 
  

   inches 
  in 
  diameter 
  at 
  the 
  stump 
  very 
  few 
  hardwoods 
  are 
  cut. 
  and 
  the 
  

   hardwood 
  forest 
  remains 
  practically 
  intact 
  upon 
  the 
  lumbered 
  area. 
  

   The 
  fore>t 
  then 
  consists 
  of 
  a 
  few 
  mature 
  pines 
  which 
  were 
  too 
  unsound 
  

   to 
  cut. 
  the 
  original 
  stand 
  of 
  young 
  and 
  middle-aged 
  pine 
  under 
  14 
  inches 
  

   in 
  diameter, 
  and 
  an 
  open 
  growth 
  of 
  mature 
  and 
  middle-aged 
  hardwoods. 
  

   Scattered 
  groups 
  of 
  hardwood 
  saplings 
  mixed 
  with 
  pine 
  form 
  the 
  

   undergrowth, 
  generally 
  much 
  injured 
  by 
  the 
  logging. 
  The 
  removal 
  

   of 
  the 
  mature 
  pine 
  has 
  admitted 
  Light 
  to 
  the 
  ground 
  and 
  fitted 
  it 
  for 
  

   the 
  germination 
  of 
  seed, 
  while 
  the 
  seed-bearing 
  capacity 
  of 
  the 
  remain- 
  

   ing 
  trees 
  is 
  increased 
  by 
  the 
  addition 
  of 
  light 
  and 
  room.
