 on our way. 
 During  the  course  of  the  afternoon  before  our  
 arrival there we  met  the  camel  postman  who  acts  
 as mail-courier between Tougourt  and  El Wad,  and  
 learnt  from  him  that  this  caravanserai  was  only  
 some  three hours further on;  so when shortly afterwards  
 we passed a small  intermediate borj,  as we all  
 felt  in  good  going  order, and expected about nightfall  
 to reach the larger and  more comfortable one of  
 more modem date,  I decided not to stop. 
 Probably the  camel  postman  had  misunderstood  
 our  question,  and,  instead  of  stating  how  long  it  
 would  take  us  to  reach  this  place  on  foot,  had

 long day’s journey through  the  heavy sand and still  
 floundering  about  among  the  dunes, with  no  caravanserai  
 to be seen. 
 As the borj was  not  in  sight, we  made a halt to  
 take  some  food,  and  then  continued  leisurely  on,  
 expecting every minute to  sight our destination. 
 At  eight  o’clock  no caravanserai was to be seen.  
 Fortunately  the  moon  was  nearly full,  and,  as  the  
 sand  was  almost  white,  the  night  was  all  but  as  
 light as the day. 
 Nine  o’clock  came,  and  still  no  borj.  At  ten
