 only  were  these  negroes  valuable  commodities  in  
 themselves,  but  they  were  extremely  useful  as  
 beasts of  burden to take the  place  of  the  numerous  
 camels  which  died  on  every  journey  across  the  
 Sahara. 
 If  only  for  strategic  reasons,  the  French  are  
 certain before long to continue  their  railway,  which  
 runs along the Marocco border,  as far as  Twat,  and  
 so  to  bring  a  European  market  into  the  centre  of  
 the  Sahara.  Probably  a  certain  amount  of  goods,  
 especially those of  high value  in  proportion  to their  
 bulk and weight,  will  continue  to  reach  Twat from  
 the Sudan,  and  so  find  their way  into  the  Barbary  
 States,  but  the  bulk  of  the produce  of  the  Sudan  
 that in former days  would  have  crossed  the Sahara  
 is  almost  certain,  when  the  new  routes  have  been  
 opened, to go southward by  steamer  and  railway  to  
 the coast. 
 The right of the French to annex Twat has been  
 somewhat  questioned,  and  as  their  action  in  doing  
 so  very  nearly  led  to  a  war  between  them  and  
 Marocco,  some  account  of  the  events which  led  to  
 this move on their part may be of interest. 
 The  treaty  of  March  18,  1845,  between  France  
 and Marocco, which fixed the boundaries of  the two  
 States  after  the  French  conquest  of  Algeria,  contains  
 no  clause relating  to  Twat.  The  value which  
 this  district  might  have  in  the  future  for  France  
 for  the  development  of  her  colonies  and  the  consolidation  
 of  her  African  dominions  did  not  until  
 long  after  the  conclusion  of  this  treaty  suggest 
 itself  to  the  French  diplomatists,  and  the omission  
 to  include  this  district  in  the  terms  of  the  treaty  
 left matters in a rather unsatisfactory condition. 
 The French maintain that  Twat  has never  been  
 an  integral  part  of  Marocco.  It  is  not  easy  to  
 estimate  the  exact  relationship  that  has  existed  in  
 the  past  between  Twat  and  the  Sultans  of  that  
 State.  The subject is an intricate  one, made all the  
 more complex by the difficulty of  obtaining accurate  
 information  as  to  the  past  history  of  such  an  
 uncivilised and remote part of the world. 
 The Sultans  of  Marocco  have  in  1315,  in 1540,  
 in  1588,  in  1667,  and  even  so  recently  as  in 1808,  
 sent expeditions into the  Sahara,  and  occupied  this  
 district  to  some  extent.  Probably,  as  is  usual  in  
 similar  cases  in  the  refractory districts of  Marocco,  
 some  tribute  was  collected,  a  few  individuals  were  
 beheaded,  and then the  expedition  returned  whence  
 it  had  come,  and,  as  soon  as  it  had  gone,  the  
 inhabitants  returned  to  their  normal  condition  of  
 internal  strife  and  general  anarchy,  and  paid  no  
 tribute  or  acknowledged  in  any  way  the  authority  
 of Marocco until the next visitation occurred. 
 While after the massacre of  the  Flatters expedition  
 the  Tawareks  were  applying  for  aid  from  
 Tripoli,  Abd-el-Kader,  the  head  in  Twat  of  the  
 Senoussia  sect,  and  one  of  the  principal  agents  of  
 the  loss  of  the  expedition,  was  endeavouring,  in  
 order  to  protect  himself,  to  persuade  the  Sultan of  
 Marocco  to  formally  annex  Twat to his dominions.  
 He appears  at  first to have met with  no response  to  
 his  letters.  But  when,  in  1882,  thes,  French,  by
