  The 
  lava 
  fields 
  of 
  tbe 
  Aiicldaiid 
  Isthmus 
  afford 
  proof 
  of 
  the 
  correctness 
  

   of 
  tbeso 
  concJusions, 
  Although 
  not 
  more 
  than 
  from 
  six 
  to 
  ten 
  miles 
  

   distant 
  in 
  a 
  straight 
  line 
  their 
  ligneous 
  plants 
  do 
  not 
  exhibit 
  the 
  same 
  

   peculiarities 
  as 
  those 
  of 
  Bangltoto. 
  Owing 
  to 
  the 
  longer 
  interval 
  that 
  has 
  

   ehxpsed 
  since 
  their 
  formation, 
  a 
  much 
  larger 
  quantity 
  of 
  soil 
  is 
  found 
  

   amongst 
  the 
  rocks, 
  so 
  that 
  in 
  many 
  places 
  the 
  titoki, 
  mangiao, 
  kohe-kohe, 
  

   rowa-rewa 
  and 
  other 
  trees 
  attain 
  their 
  average 
  dimensiojis. 
  The 
  largest 
  

   specimens 
  of 
  Grlsellnia 
  Iiicida 
  that 
  I 
  have 
  met 
  with 
  grew 
  amongst 
  thorough 
  

   scoria 
  near 
  Mount 
  Eden, 
  hut 
  owing 
  to 
  the 
  comparatively 
  small 
  amount 
  of 
  

   atmospheric 
  moisture 
  the 
  leaves 
  present 
  an 
  ordinary 
  appearance, 
  and 
  the 
  

   extremely 
  luxuriant 
  foliage 
  so 
  characteristic 
  of 
  the 
  woody 
  vegetation 
  of 
  

   Eangitoto

  for 
  my 
  

   knowledge 
  of 
  several 
  interesting

  not 
  observed 
  by 
  me,

  have
