  Highest 
  reach 
  of 
  the 
  modern 
  inundation. 
  3. 
  Alluvial 
  plain 
  of 
  

   Derr, 
  cultivated 
  to 
  near 
  the 
  Temple 
  (4). 
  5. 
  The 
  plateau 
  containing 
  the 
  Fluviatile 
  

   Shells. 
  6. 
  The 
  rounded, 
  irregularly 
  shaped 
  sandstone-hills. 
  7. 
  The 
  Desert 
  and 
  

   its 
  sand-drift, 
  down 
  to 
  the 
  limits 
  of 
  the 
  Inundation. 
  

  

  The 
  left 
  bank 
  was 
  not 
  examined. 
  

  

  Beloiv 
  the 
  level 
  of 
  the 
  above 
  plateau, 
  and 
  a 
  little 
  further 
  down 
  the 
  

   river 
  on 
  the 
  opposite 
  bank, 
  is 
  the 
  Temple 
  of 
  Amada, 
  which 
  existed 
  

   in 
  the 
  time 
  of 
  Tuthmosis 
  III., 
  about 
  b.c 
  1490. 
  

  

  Looking 
  southward 
  from 
  Korosko, 
  forty-four 
  miles 
  north 
  of 
  Derr, 
  

   an 
  excellent 
  view 
  of 
  the 
  above 
  flat 
  can 
  be 
  obtained, 
  and 
  its 
  sweep 
  

   around 
  the 
  river-valley 
  can 
  be 
  easily 
  traced. 
  About 
  25 
  miles 
  north- 
  

   ward 
  on 
  the 
  same 
  terrace-flat, 
  and 
  at 
  elevations 
  of 
  100 
  feet 
  and 
  

   more, 
  I 
  found 
  the 
  same 
  Cyrena* 
  in 
  the 
  same 
  reddish 
  sandy 
  soil, 
  

   and 
  in 
  excavations 
  made 
  by 
  the 
  natives. 
  Along 
  with 
  these, 
  strewn 
  

   on 
  the 
  surface, 
  in 
  crannies 
  of 
  the 
  rocks, 
  and 
  under 
  detached 
  masses, 
  

   I 
  found 
  quantities 
  of 
  the 
  small 
  spiral 
  univalve, 
  Bulimus 
  pullus. 
  

  

  This 
  species 
  and 
  the 
  above-mentioned 
  Cyrena 
  were 
  traced 
  inland 
  

   for 
  upwards 
  of 
  three-quarters 
  of 
  a 
  mile 
  from 
  the 
  river, 
  and 
  until 
  

   the 
  country 
  became 
  broken 
  up 
  into 
  ravines 
  and 
  rugged 
  worn 
  cliffs. 
  

   The 
  abrupt 
  appearance 
  of 
  the 
  left 
  bank, 
  rising 
  rapidly 
  to 
  an 
  emi- 
  

   nence, 
  and 
  the 
  flat 
  plateau 
  opposite 
  appeared 
  to 
  indicate 
  that 
  the 
  

   ancient 
  bed 
  of 
  the 
  river 
  was 
  on 
  the 
  right 
  side.
