The  tannin  from  all  of  the  parts  gave  a  green  color  and  precipi- 
tate with  ferric  chloride,  and  a  yellow  precipitate  with  bromine 
water,  thus  indicating  its  probable  identity  with  that  from  oak  bark. 
The  ash  consisted  of  calcium  phosphate,  with  some  sulphate  and 
carbonate. 
ECONOMICS. 
So  far  as  this  country  is  concerned,  the  Austrian  pine  is  used  only 
as  an  ornamental  tree,  for  which  purpose,  however,  it  is  in  unusual 
favor.  In  its  native  locality,  Austria  and  southern  France,  it,  with 
the  closely  related  Pinus  Laricio,  furnishes  a  considerable  quantity 
of  turpentine. 
PINUS  PALUSTRIS,  MILLER. 
LONG  LEAVED  PINE,  SOUTHERN  YELLOW  PINE. 
GENERAL  CHARACTERS  AND  DISTRIBUTION. 
The  stem  and  leaves  of  this  species  have  been  studied  micro- 
scopically, and  the  leaves  and  bark  chemically.  The  long-leaved 
pine  is  one  of  the  most  valuable  members  of  the  genus.  It  is  the 
chief  source  of  the  terebinthinous  products  of  this  country,  and  its 
wood  contributes  no  small  part  to  the  lumber  industry. 
According  to  the  "  Report  of  the  Chief  of  the  Division  of 
Forestry  "  for  1891,  this  pine  is  distributed  through  all  the  South 
Atlantic  and  Gulf  States,  at  some  distance  from  the  coast,  and  cover- 
ing a  belt  about  125  miles  in  width,  interrupted  only  by  the  allu- 
vial plains  of  the  Mississippi  and  Red  Rivers,  in  Louisiana  and  Texas. 
In  addition,  there  is  found  in  western  Georgia  and  Alabama  an  ex- 
tension in  islands  or  patches,  northward  to  latitude  34-5°.  In  Vir- 
ginia this  species  has  become  almost  extinct,  being  replaced  by  the 
loblolly  pine. 
In  North  Carolina  the  forests  exclusively  of  long-leafed  pine  begin 
south  of  Bogue  Inlet,  with  a  width  of  95  to  125  miles  inland,  and 
extending  southward  to  the  State  line,  covering  about  6,500,000 
acres ;  this  is  largely  tapped  for  turpentine. 
In  South  Carolina  the  pine  belt  is  1 50  miles  wide,  much  of  which 
is  still  untouched.  In  Georgia  the  flat  woods  of  the  shore  have 
mostly  been  stripped  of  this  pine,  but  the  vast  interior  plane  of 
17,000  square  miles  is  almost  exclusively  covered  with  it.  In 
Florida  it  may  be  traced  on  the  Atlantic  Coast  as  far  north  as  St. 
Augustine.    In  western  Florida,  large  areas  are  pretty  well  ex-
