  Dr* 
  Behr 
  'exhibited 
  and 
  described 
  the 
  nature 
  of 
  a 
  species 
  of 
  

   mangrove, 
  (^Avicenus 
  officinalis^ 
  adapted 
  to 
  this 
  State, 
  and 
  found 
  

   in 
  New 
  Zealand. 
  He 
  had, 
  after 
  considerable 
  difficulty, 
  procured 
  

   some 
  of 
  the 
  seed 
  in 
  a 
  perfect 
  condition, 
  and 
  was 
  experimenting 
  in 
  

   raising 
  the 
  tree. 
  It 
  is 
  used 
  to 
  protect 
  plantations 
  against 
  tides. 
  

   The 
  trees 
  grow 
  in 
  the 
  sea, 
  as 
  far 
  out 
  as 
  the 
  low-tide 
  mark. 
  The 
  

   seeds 
  are 
  never 
  dormant, 
  but 
  begin 
  to 
  germinate 
  as 
  soon 
  as 
  mature, 
  

   whether 
  in 
  air, 
  earth, 
  or 
  water. 
  They 
  always 
  grow 
  where 
  not 
  

   wanted, 
  and 
  do 
  not 
  always 
  grow 
  where 
  they 
  are 
  wanted. 
  

  

  S. 
  C. 
  Hastings 
  read 
  a 
  short 
  paper 
  on 
  " 
  Correlation 
  of 
  Forces, 
  

   and 
  the 
  Indestructibility

  of

  The 
  various 
  modes 
  by 
  which 
  swamp 
  and 
  overflowed 
  lands 
  may 
  best 
  be 
  re- 
  

   claimed 
  and 
  brought 
  into 
  a 
  state 
  oF 
  cultivation 
  will 
  of 
  course 
  depend 
  on 
  many 
  

   circumstances, 
  of 
  which 
  the 
  nature 
  of 
  the 
  soil 
  is 
  one 
  of 
  the 
  chief 
  considerations 
  ; 
  

   also, 
  the 
  rise 
  and 
  fall 
  of 
  the 
  tides, 
  together 
  with 
  sluices 
  of 
  suflBcient 
  capacity 
  

   properly 
  placed 
  to 
  drain 
  the 
  laud 
  in 
  the 
  interior, 
  at 
  least 
  eighteen 
  inches 
  below 
  

   the 
  general 
  level 
  of 
  the 
  surface. 
  These 
  are 
  essential 
  conditions, 
  on 
  which 
  alone 
  

   the 
  work 
  of 
  reclamation 
  can 
  be 
  commenced 
  with 
  any 
  hope 
  of 
  success. 
  

  

  This 
  subject 
  divides 
  itself 
  into 
  so 
  many 
  branches, 
  minute 
  in 
  themselves, 
  yet
