  merchantable 
  timber 
  increases 
  but 
  slightly. 
  In 
  proportion 
  to 
  the 
  

   total 
  height 
  the 
  greatest 
  merchantable 
  length 
  is 
  obtained 
  from 
  trees 
  

   about 
  20 
  inches 
  in 
  diameter, 
  and, 
  as 
  with 
  the 
  Shortleaf, 
  this 
  amounts 
  

   to 
  only 
  one-half 
  the 
  total 
  height 
  of 
  the 
  tree. 
  The 
  merchantable 
  length 
  

   is 
  less 
  than 
  the 
  clear 
  length 
  in 
  trees 
  below 
  20 
  inches 
  in 
  diameter, 
  but 
  

   in 
  large 
  trees 
  the 
  reverse 
  is 
  true.

  Practical 
  Value 
  of 
  the 
  Loblolly 
  Pink 
  as 
  compared 
  with 
  the 
  Shortleaf 
  Pixe. 
  

  

  In 
  case 
  conservative 
  lumbering 
  is 
  undertaken 
  upon 
  the 
  tract 
  of 
  the 
  

   Sawyer 
  & 
  Austin 
  Lumber 
  Company, 
  it 
  will 
  be 
  possible 
  to 
  increase 
  the 
  

   percentage 
  of 
  the 
  most 
  valuable 
  species 
  in 
  the 
  forest 
  of 
  the 
  future. 
  

   As 
  already 
  said, 
  there 
  is 
  no 
  doubt 
  whatever 
  that 
  an 
  increase 
  in 
  the 
  

   stand 
  of 
  pine 
  and 
  a 
  decrease 
  in 
  that 
  of 
  hardwoods 
  would 
  very 
  mate- 
  

   rially 
  increase 
  the 
  value 
  of 
  the 
  forest. 
  More 
  than 
  this, 
  there 
  are 
  notable 
  

   differences 
  betw 
  T 
  een 
  the 
  two 
  species 
  of 
  pine, 
  and 
  such 
  differences 
  should 
  

   also 
  be 
  taken 
  into 
  consideration, 
  and 
  the 
  species 
  which 
  gives 
  promise
