In  the  pits  X.  and  XI.,  at  the  level  when  the  filtration  water  prevented  further  exca- 
vation, a boring  tool  was  apphed,  and  what  it  brought  up  showed  that  the  same  sand 
continued  at  a further  depth  of  16  feet. 
The  pits  XII.  and  XIII.  were  sunk  on  the  right  bank ; XII.  at  its  edge,  which  rose 
above  the  highest  inundation  level.  They  first  passed  through  27  inches  of  pure  mud 
{limm),  which  rested  on  107  inches  of  micaceous  sand  mixed  with  a little  mud,  below 
which  there  were  85  inches  of  grey  sand,  and  inches  of  magnetic  iron  sand ; lastly, 
60^  inches  of  a mixture  of  sand  and  mud,  when  they  were  stopped  by  the  filtration 
water.  Thus —

Being  desirous  of  reaching,  if  possible,  the  rock  which  forms  the  base  of  the  valley, 
they  sank  a pit  in  the  same  locality,  but  in  the  vicinity  of  the  bounding  hill,  304  yards 
from  the  cultivable  land.  They  chose  a projection  of  the  base  of  the  hill,  which  they 
conceived  would  be  composed  of  the  gravel  that  constitutes  the  soil  of  the  desert  land. 
The  result  of  their  excavation  was —
