  Aden 
  is 
  situated 
  on 
  the 
  south 
  coast 
  of 
  Arabia, 
  in 
  the 
  province 
  

   of 
  Yemen 
  (the 
  Arabia 
  Felix 
  of 
  the 
  Ancients), 
  and 
  is 
  118 
  miles 
  

   east 
  of 
  the 
  Strait 
  of 
  Bab-el-Mandeb, 
  in 
  latitude 
  12° 
  47' 
  N., 
  

   and 
  longitude 
  45° 
  0' 
  E. 
  

  

  The 
  settlement 
  consists 
  of 
  two 
  small 
  rocky 
  peninsulas, 
  

   Aden 
  proper 
  on 
  the 
  east 
  and 
  Little 
  Aden 
  on 
  the 
  west, 
  sepa- 
  

   rated 
  by 
  a 
  bay 
  forming 
  the 
  harbour, 
  and 
  a 
  strip 
  of 
  land 
  on 
  

   the 
  Arabian 
  coast, 
  about 
  six 
  miles 
  long 
  and 
  three 
  broad. 
  

   The 
  total 
  area 
  is 
  about 
  70 
  square 
  miles. 
  

  

  The 
  inhabited 
  part, 
  known 
  as 
  Aden 
  proper, 
  is 
  a 
  high 
  rocky 
  

   peninsula, 
  almost 
  an 
  island, 
  and 
  is 
  connected 
  with 
  the 
  main- 
  

   land 
  by 
  a 
  narrow, 
  flat, 
  sandy 
  isthmus. 
  It 
  is 
  about 
  five 
  miles 
  

   long 
  and 
  three 
  wide, 
  and 
  consists 
  of 
  hills 
  of 
  bare 
  brown 
  rock, 
  

   the 
  highest, 
  Shum-shum, 
  attaining 
  a 
  height 
  of 
  1760 
  feet. 
  Its 
  

   volcanic 
  origin 
  is 
  shown 
  by 
  the 
  existence 
  of 
  a 
  large 
  extinct 
  

   crater 
  situated 
  at 
  the 
  north-east 
  corner. 
  From 
  this 
  spurs 
  

   project 
  in 
  all 
  directions 
  into 
  the 
  sea, 
  and 
  the 
  surface 
  is 
  much 
  

   broken 
  up 
  and 
  is 
  uninhabitable, 
  except 
  in 
  a 
  kw 
  places. 
  

  

  The 
  lava 
  is 
  of 
  different 
  colours, 
  but 
  brown 
  and 
  grey 
  pre- 
  

   dominate. 
  Gypsum 
  and 
  pumice-stone 
  are 
  also 
  found, 
  and 
  

   several 
  thousand 
  tons 
  of 
  the 
  latter 
  are 
  annually 
  exported 
  to 
  

   Bombay. 
  

  

  The 
  hills 
  are 
  not 
  so 
  bare 
  of 
  vegetation 
  as 
  at 
  a 
  distance 
  

   they 
  appear 
  to 
  be. 
  After 
  a 
  fall 
  of 
  rain 
  (of 
  late 
  years 
  no 
  

   uncommon 
  occurrence) 
  patches 
  of 
  verdure 
  appear; 
  and 
  if 
  the
