  pottery, 
  the 
  tiiick 
  blackish 
  potteiy 
  with 
  yellow 
  glaze 
  being 
  found 
  

   about 
  5 
  feet 
  dowu. 
  I 
  noticed 
  no 
  pottery 
  of 
  this 
  type 
  of 
  colour 
  in 
  the 
  

   market 
  at 
  Palma. 
  The 
  other 
  fragments 
  were 
  nearer 
  the 
  surface. 
  

   'J'he 
  pottery 
  and 
  marine 
  shells 
  probably 
  are 
  derived 
  from 
  refuse 
  

   material 
  and 
  seaweed, 
  used 
  to 
  fertilize 
  the 
  soil, 
  for 
  the 
  island 
  has 
  been 
  

   agriculturally 
  occupied 
  certainly 
  from 
  Phoenician 
  times 
  and 
  probably 
  

   much 
  earlier. 
  The 
  depth 
  of 
  the 
  deposit 
  gradually 
  thins 
  off 
  up 
  the 
  

   hill 
  above. 
  The 
  section 
  observed 
  is 
  a 
  considerable 
  distance 
  in 
  from 
  

   the 
  sea-front, 
  and 
  about 
  60 
  feet 
  above 
  sea-level.

  Overburden 
  (containing 
  non-marine 
  and 
  marine 
  mollusca 
  and 
  

  

  pottery) 
  varying 
  from 
  6-8 
  feet 
  in 
  thickness.

  10-15

  Alcudia} 
  — 
  The 
  Holocene 
  deposits 
  at 
  Alcudia 
  form 
  a 
  low 
  sea-cliff 
  

   quite 
  near 
  the 
  sea, 
  there 
  being 
  very 
  little 
  foreshore 
  — 
  in 
  some 
  parts 
  

   none. 
  The 
  farmers 
  use 
  seaweed 
  for 
  manure, 
  and 
  this 
  probably 
  

   accounts 
  for 
  the 
  mixture 
  of 
  non-marine 
  and 
  marine 
  shells 
  in 
  the 
  

   course 
  of 
  ages. 
  The 
  land 
  has 
  a 
  slight 
  slope 
  downwards 
  to 
  the 
  

   sea-front, 
  and 
  the 
  soil 
  has 
  no 
  doubt 
  been 
  washed 
  down 
  in 
  that 
  

   direction, 
  and 
  caused 
  the 
  melange. 
  

  

  Manresa. 
  — 
  These 
  Holocene 
  deposits 
  were 
  near 
  the 
  bridge 
  above 
  the 
  

   railway, 
  and 
  were 
  in 
  places 
  quite 
  10 
  feet 
  thick.^

  Bellver. 
  — 
  The 
  hill 
  on 
  which 
  Bellver 
  Castle 
  stands 
  is 
  about 
  350 
  feet 
  

   O.D., 
  and 
  is 
  very 
  rich 
  in 
  mollusca. 
  The 
  Holocene 
  deposit 
  was 
  near 
  

   the 
  summit 
  of 
  the 
  hill. 
  

  

  Alcudia 
  (Port 
  of). 
  — 
  The 
  recent 
  land 
  and 
  freshwater 
  mollusca 
  were 
  

   found 
  on 
  the 
  large 
  stretch 
  of 
  blown 
  sand, 
  with 
  swampy 
  bits 
  of 
  land 
  in 
  

   parts 
  of 
  it, 
  which 
  is 
  dammed 
  off 
  from 
  the 
  sea 
  by 
  a 
  strand 
  of 
  natural 
  

   concrete 
  containing 
  abundance 
  of 
  Cerithium 
  vulgatum, 
  Conns 
  mediter- 
  

   raneus, 
  and 
  Helix 
  Pisana, 
  etc. 
  The 
  Avhole 
  of 
  the 
  shells 
  from 
  Alcudia 
  

   were 
  procured 
  in 
  less 
  than 
  two 
  hours. 
  

  

  One 
  of 
  the 
  land 
  shells 
  from 
  Porto 
  Pi 
  deserves 
  a 
  note 
  specially 
  to 
  

   itself. 
  It 
  was 
  found 
  adhering 
  to 
  a 
  rock 
  in 
  the 
  full 
  blaze 
  of 
  sunlight.

  The 
  old 
  walled 
  Roman 
  town 
  of 
  Alcudia 
  is 
  a 
  mile 
  from 
  the 
  sea
