 thundering lie, or to get out  of  the  difficulty as best  
 I might. 
 In this case, however, he  had  done  me a service,  
 for  as  soon  as  I  had  had  time  to  recover from the  
 first shock of  the staggering request which had been  
 made to me,  it struck me that I might  make  use  of  
 the thirst for knowledge of those Tawareks to obtain  
 before their faces those very photos which I had surreptitiously  
 been trying to take behind their backs. 
 I  told  them  that  I  could  not  show  them  the  
 interior  of  the  box,  as that would necessitate taking  
 it to pieces,  and,  as it was a delicate machine, would  
 probably  spoil  it,  but  that  if  they  would  stand  in  
 front of it they would  be able to see how one part of  
 it worked, and I told them to look at the shutter. 
 Two of the Tawareks, with one of the slaves and  
 some of the children, immediately placed themselves  
 in  front  of  the  camera,  all  agog to see  the working  
 of that wonderful machine. 
 I  was  not,  of  course,  able  to  pose them, but as  
 one of them laid  his  hand upon the shoulder  of  the  
 child next to him  to turn  her  round  to  look  at  the  
 shutter just as I made  the exposure,  he  fell  into  an  
 attitude  which  did  much  to  relieve  the  stiffness  of  
 the group. 
 They  were,  perhaps  naturally,  not  quite  clear  
 from what they had  seen as to the way the machine  
 worked, but as I told  them that it was impossible to  
 explain  it  any  further  without  taking  the  thing  to  
 pieces, they were reluctantly compelled to be content  
 with what they had seen.
