t   December,  1905. 
In  the  Winter  of  1846-47,  fifteen  more  acres  were  incorporated 
with  the  Botanic  Garden  by  the  suppression  of  the  Royal  Forcing 
and  Kitchen  Gardens.  To  the  land  thus  acquired  the  herbaceous 
and  grass  collections  were  transferred. 
In  1 85 1  thirteen  acres  were  taken  from  the  Deer  Park  (see  map, 
Plate  I)  and  added  to  the  Queen's  Cottage  grounds,  an  enclosure  on 
the  southwestern  corner  of  the  pleasure  grounds  reserved  for  the 
private  use  of  the  Crown. 
A  further  acquisition  was  made  in  1853,  when  three  acres  of  the 
piece  of  ground  known  as  the  paddock,  and  adjoining  the  former 
kitchen  garden,  were  added  to  the  northeastern  portion  of  the 
Botanic  Garden.  In  these  a  separate  collection  of  British  plants  and 
one  of  hardy  medicinal  plants  were  set  out. 
In  1855  Dr.  (now  Sir)  J.  D.  Hooker,  son  of  Sir  William  Hooker, 
who  was  then  70  years  of  age,  was  appointed  assistant  director,  and 
in  1865,  on  the  death  of  his  father,  he  succeeded  to  the  directorship 
without  an  assistant.  The  arboretum  begun  by  his  predecessor  was 
developed  and  in  a  great  measure  remodelled  by  him,  and  we  have, 
so  to  speak,  an  index  of  its  increasing  importance  from  his  annual 
reports;  thus,  we  find  in  the  report  for  187 1  that  the  heading 
"  Pleasure  Grounds  "  has  been  replaced  by  the  "  Pleasure  Grounds 
and  Arboretum."  In  the  report  for  1872  this  has  been  further 
modified  to  the  " Arboretum  in  the  Pleasure  Grounds,"  and  in  1878 
the  transformation  is  complete,  the  former  expressions  having  been 
entirely  supplanted  by  the  ''Arboretum,"  which  stands  alone. 
Soon  after  Dr.  Hooker's  appointment  as  director,  the  medicinal 
and  British  collections  were  done  away  with,  and  in  1869  the  whole 
of  the  herbaceous  collection  was  rearranged,  new  potting  sheds,  a 
seed  room,  frames,  etc.,  being  added  to  it. 
A  small  students'  garden,  in  which  it  was  permitted  to  gather 
specimens,  was  subsequently  made  in  1 880  on  the  site  of  the  re- 
cently completed  wing  of  the  Herbarium  building. 
In  1875  Mr.  (now  Sir)  William  Turner  Thiselton-Dyer  was  ap- 
pointed assistant  director,  and,  on  the  retirement  of  Sir  J.  D. 
Hooker,  in  1885,  became  Director,  a  position  which  he  still  holds. 
Dr.  (now  Sir)  D.  Morris  was  appointed  assistant  director  to  Sir  WT. 
T.  Thiselton-Dyer  in  1886,  but,  since  his  subsequent  appointment 
as  Commissioner  of  Agriculture  at  Barbados  in  1898,  the  post  which 
he  formerly  occupied  has  remained  unfilled.
