1038.  Forest  planting  in  nnforested  areas. — Successful  at-
tempts have  been  made  to  grow  forests  in  the  prairie  regions  of
the  West  (the  "plains"  east  of  the  looth  meridian)  by  trans-
planting seedlings  and  cultivating  them  and  protecting  them  until
they  are  large  enough  to  shade  the  ground  and  hold  their  litter.
These  forests  provide  their  owner  shelter  for  orchards,  provide
fire- wood,  fence-posts,  and  some  lumber  for  building  material.
In  Gascony  (France)  an  arid,  sandy  area  was  planted  with  pines
to  hold  the  sand.  The  swamp  regions  here  were  also  reclaimed
by  planting  forests.  What  was  once  an  unhealthful  area  is  now
a  health-resort.  Certain  species  of  eucalyptus  which  grow  in
wet  ground  have  been  planted  in  swampy  lands  to  drain  them.
This  tree  requires  a  great  amount  of  water  and  transpires  large
amounts.
