ville,  in  South  Carolina,  Augusta,  Ga.,  and  Oakland,  Cal. 
At  Charleston,  Summerville  and  Augusta  the  trees  have  with- 
stood a  minimum  temperature  of  1 50  F.,  but  they  have  been  pro- 
tected by  surrounding  trees  and  buildings.  At  Mobile,  Ala.,  the 
trees  have  grown  and  fruited  in  protected  situations,  while  in  ex- 
posed places  they  have  been  repeatedly  destroyed  by  frosts.  While 
the  camphor  tree  will  grow  on  almost  any  soil  that  is  not  too  wet, 
it  does  best  on  a  well-drained  sandy  or  loamy  soil,  and  it  responds 
remarkably  well  to  the  application  of  fertilizers.  Its  growth  is  com- 
paratively slow  on  sterile  soils,  but  under  favorable  conditions  it

grown  in  the  United  States.  In  the  dotted  area  protection  from  cold  will  be

sometimes  grows  very  rapidly.  An  instance  is  recorded  of  a  cam- 
phor tree  in  Italy  a  foot  in  diameter  and  90  feet  high,  eight  years 
from  the  seed.  Under  ordinary  conditions,  however,  such  a  girth 
is  not  often  attained  in  less  than  twenty-five  years,  and  such  a  height 
is  rarely  attained  in  a  century.  Under  favorable  conditions  an  aver- 
age of  30  feet  in  height,  with  trunks  6  to  8  inches  in  diameter  at  the 
base,  may  be  expected  in  trees  ten  years  from  the  seed.
