  It 
  may 
  be 
  noted 
  here 
  that 
  

   the 
  lumberman 
  makes 
  no 
  distinction 
  between 
  Loblolly 
  and 
  Shortleaf 
  

   Pine, 
  nor 
  is 
  any 
  distinction 
  made 
  in 
  the 
  trade, 
  both 
  being 
  sold 
  under 
  

   the 
  name 
  of 
  "Yellow 
  Pine." 
  In 
  the 
  woods, 
  however, 
  the 
  lumbermen 
  

   distinguish 
  two 
  kinds 
  of 
  timber 
  Heart 
  Pine 
  and 
  Bull 
  Pine. 
  The 
  lat- 
  

   ter 
  is 
  called 
  also 
  Second 
  Growth 
  Pine. 
  These 
  terms 
  apply 
  roughly 
  

   to 
  the 
  two 
  different 
  species, 
  the 
  Heart 
  to 
  the 
  Shortleaf 
  and

  to 
  the 
  Loblolly, 
  because 
  by 
  ""Heart" 
  Pine 
  is 
  understood 
  a 
  pine 
  whose 
  

   wood 
  is 
  mostly 
  heart, 
  with 
  very 
  little 
  sap:

  a 
  pine 
  

   with 
  a 
  large 
  amount 
  of 
  sapwood; 
  and 
  as 
  a 
  rule 
  the 
  Loblolly 
  contains 
  a 
  

   greater 
  percentage 
  of 
  sapwood 
  than 
  the 
  Shortleaf.

  can 
  never
