THti JOURNEY 379 



Zambesi, our farthest inland point, arriving there the next morning and 

 starting back the following day, September 13. We reached Bulawayo 

 again on September 14. Here the party divided, some going southward 

 to Cape Town and thence to England by direct steamer, while others, 

 including the writer, went eastward for a longer journey. We reached 

 Salisbury, the capital of Ehodesia, on September 15 ; Umtali, on Septem- 

 ber 16, and Beira, in Portuguese East Africa, on September 17. There 

 the homeward journey was begun in the steamer Durham Castle, which 

 had been especially chartered to return by the east coast of Africa, the 

 Suez canal, and the Mediterranean. Marseilles was reached on October
