  while 
  the

  they 
  do 
  to 
  pine

  is 
  

   trifling. 
  They 
  also

  the

  thus 
  preparing

  THE 
  FOREST. 
  

  

  Although 
  the 
  forests 
  of 
  this 
  locality 
  are 
  commonly 
  known 
  as 
  "pine 
  

   woods," 
  pine 
  being 
  the 
  principal 
  merchantable 
  species, 
  a 
  pure 
  growth 
  

   of 
  pine 
  very 
  seldom 
  occurs. 
  Except 
  over 
  limited 
  areas 
  the 
  pine 
  is 
  

   always 
  in 
  mixture 
  with 
  the 
  hardwoods. 
  On 
  the 
  bottom 
  lands 
  along 
  the 
  

   streams, 
  pure 
  hardwood 
  forests 
  occur. 
  Several 
  distinct 
  types 
  of 
  forest 
  

   growth 
  may 
  therefore 
  be 
  observed, 
  and 
  are 
  distinguished 
  by 
  the 
  lum- 
  

   bermen. 
  These 
  types 
  are: 
  

  

  1. 
  Pine 
  ridge. 
  

  

  2. 
  Pine 
  flat. 
  

  

  3. 
  Hardwood 
  bottom. 
  

  

  Since 
  no 
  topographical 
  maps 
  of 
  the 
  tract 
  were 
  available, 
  and 
  since 
  

   the 
  occurrence 
  of 
  these 
  types 
  is 
  dependent 
  mainly 
  upon 
  differences 
  in 
  

   elevation 
  and 
  slope, 
  it 
  is 
  impossible 
  to 
  estimate 
  accurately 
  the 
  area 
  

   occupied 
  by 
  each. 
  From 
  the 
  valuation 
  surveys, 
  however, 
  a 
  rough 
  

   idea 
  of 
  their 
  extent 
  was 
  obtained, 
  and 
  the 
  per 
  cent 
  of 
  the 
  total 
  forest 
  

   area 
  each 
  occupies 
  is 
  assumed 
  to 
  be 
  about 
  as 
  follows: 
  

  

  Per 
  cent. 
  

  

  Pine 
  ridge 
  1 
  65 
  

  

  Pine 
  flat 
  20 
  

  

  Hardwood 
  bottom 
  15 
  

  

  As 
  each 
  of 
  these 
  types 
  has 
  a 
  tree 
  growth 
  in 
  many 
  ways 
  peculiar 
  to 
  

   itself, 
  the 
  forest 
  will 
  be 
  described 
  silviculturally 
  under 
  these 
  three 
  

   headings. 
  From 
  the 
  standpoint 
  of 
  the 
  lumberman, 
  however, 
  the 
  first 
  

   two 
  types 
  may 
  be 
  thrown 
  together 
  under 
  the 
  general 
  heading 
  "Pine 
  

   lands," 
  since 
  from 
  this 
  point 
  of 
  view 
  there 
  is 
  very 
  little 
  to 
  distinguish 
  

   them. 
  In 
  the 
  first 
  place, 
  the 
  forests 
  of 
  the 
  pine 
  lands 
  will' 
  be 
  briefly 
  

   described, 
  from 
  the 
  standpoint 
  of 
  their 
  merchantable 
  product. 
  

  

  THE 
  MERCHANTABLE 
  FOREST. 
  

  

  PIXE 
  LAXDS. 
  

  

  Occupying 
  about 
  85 
  per 
  cent 
  of 
  the 
  total 
  area, 
  the 
  pine 
  lands 
  form, 
  

   and 
  will 
  continue 
  to 
  form, 
  the 
  principal 
  source 
  of 
  income. 
  Although 
  

   the 
  lands 
  of 
  the 
  hardwood-bottom 
  type 
  contain 
  much 
  valuable 
  timber, 
  

   they 
  coyer 
  too 
  small 
  an 
  area 
  to 
  compete 
  in 
  commercial 
  value 
  with 
  the 
  

   pine 
  lands. 
  

  

  The 
  stand 
  on 
  the 
  pine 
  lands 
  is 
  shown 
  by 
  the 
  table 
  following, 
  which 
  

   gives 
  the 
  average 
  number 
  of 
  trees, 
  the 
  percentage 
  in 
  mixture, 
  and 
  the 
  

   average 
  diameter 
  at 
  breastheight 
  (4i 
  feet) 
  11 
  of 
  the 
  most 
  important 
  

  

  "All 
  the 
  tables 
  contained 
  in 
  this 
  report 
  are 
  based 
  on 
  diameter 
  measurements 
  made 
  

   at 
  breastheight, 
  or 
  4.] 
  feet 
  from 
  the

  To 
  reduce 
  approximately 
  diameter 
  

   breasthigh 
  to 
  diameter 
  on 
  the

  add 
  2 
  inches 
  to 
  the 
  former. 
  The 
  exact 
  rela- 
  

   tion 
  between 
  these 
  two
