This evening I gave an entertainment for the Battalion. This is a big sort of show called by the Sudanese a "Darluka". Much "boosa" or Sudanese beer is given out, and everyone turned up at the 12th Sudanese quarters at 6.30. Colonel Lewis and I paid them a visit after mess. All the tribes danced to the music of tom-toms and the accompaniment of singing in perfect time...In the end they all got very drunk and women and abandoned themselves to fiercer orgies. I was discreet and left the scene early. … Poor devils, why should they not amuse themselves in their own fashion? and, after all, as Sir Richard Burton said, morality is largely a question of geography.
