  Mr. 
  Clieeseman, 
  to 
  whom 
  I 
  am 
  indebted 
  for 
  tlie 
  samples 
  

   just 
  alluded 
  to, 
  forwarded 
  some 
  of 
  the 
  water 
  to 
  Mr. 
  Skey, 
  of 
  WelHngton, 
  

   whose 
  report, 
  just 
  received, 
  I 
  will 
  now 
  read. 
  

  

  The 
  other 
  sample 
  I 
  have 
  now 
  to 
  mention 
  is 
  a 
  hot 
  spring 
  at 
  Motuhora 
  

   (Whale 
  Island), 
  in 
  the 
  Bay 
  of 
  Plenty. 
  Here 
  the 
  water 
  flows 
  out 
  of 
  a 
  valley 
  

   in 
  large 
  quantities 
  into 
  the 
  sea, 
  the 
  heat 
  being 
  so 
  great 
  as 
  to 
  cause 
  volumes 
  

   of 
  steam 
  to 
  rise 
  as 
  the 
  water 
  flows 
  over 
  the 
  sand. 
  The 
  temperature 
  of 
  this 
  

   spring, 
  where 
  it 
  rises 
  from 
  the 
  ground, 
  is 
  198° 
  Fahr., 
  the 
  taste 
  being 
  

   extremely 
  acid, 
  and 
  the 
  water 
  very 
  clear. 
  I 
  am 
  indebted 
  to 
  Mr. 
  Tunny 
  for

  Notes 
  of 
  a 
  Traditional 
  Change 
  in 
  the 
  Coast 
  line 
  at 
  Manukau 
  

   Heads. 
  By 
  S. 
  Percy 
  Smith. 
  

   [Read 
  before 
  the 
  Auckland 
  Institute, 
  18th 
  November, 
  1878.] 
  

   Some 
  thirteen 
  years 
  ago, 
  when 
  encamped 
  one 
  night 
  with 
  a 
  party 
  of 
  natives 
  

   on 
  the 
  long 
  beach 
  which 
  extends 
  from 
  Manukau 
  to 
  Waikato 
  Heads, 
  the 
  

   conversation 
  over 
  the 
  camp 
  fire 
  turned 
  upon 
  some 
  old 
  tribal 
  boundaries, 
  

   one 
  of 
  which 
  ended 
  at 
  a 
  place 
  said 
  by 
  Aihepene 
  Eaihau, 
  the 
  narrator 
  (who 
  

   was 
  then 
  living 
  at 
  Waiuku, 
  but 
  who 
  now, 
  having 
  married 
  the 
  Princess 
  

   Sophia, 
  resides 
  in 
  the 
  King's 
  country), 
  to 
  be 
  now 
  covered 
  by 
  the 
  sea. 
  Upon 
  

   enquiring 
  further 
  of 
  him 
  as 
  to 
  this 
  particular 
  place, 
  he 
  informed 
  me 
  that 
  

   many 
  generations 
  ago 
  the 
  coast-line 
  extended 
  much 
  further 
  seaward 
  than 
  it 
  

   does 
  at 
  present, 
  projecting 
  in 
  a 
  curved 
  line 
  from 
  Manukau 
  Heads 
  to 
  the 
  

   Waikato 
  Eiver. 
  This 
  point 
  he 
  described 
  as 
  a 
  low, 
  sandy 
  country, 
  with 
  

   numerous 
  sand-dunes, 
  fresh-water 
  lakes, 
  with 
  clumps 
  of 
  tall 
  manuka 
  trees 
  

   scattered 
  over 
  its 
  surface. 
  

  

  The 
  lakes 
  were 
  much 
  resorted 
  to 
  by 
  the 
  natives 
  in 
  those 
  days, 
  on 
  

   account 
  of 
  the 
  great 
  number 
  of 
  eels 
  found 
  in 
  them. 
  

  

  He 
  further 
  stated 
  that 
  it 
  was 
  a 
  three 
  days' 
  journey 
  at 
  that 
  time 
  for 
  a 
  

   man 
  following 
  the 
  beach 
  from 
  Manukau 
  to 
  Waikato 
  Heads, 
  whereas 
  the 
  

   |)resent 
  coast-line 
  is 
  a 
  very 
  nearly 
  straight 
  line, 
  and 
  the 
  distance 
  may 
  be
