To obviate as far as possible the recurrence of such a disaster to a new store of goods which he was now asking Dr. Kirk to send him, Livingstone wrote a letter to the Sultan of Zanzibar, 20th April, 1869, in which he frankly and cordially acknowledged the benefit he had derived from the letter of recommendation his Highness had given him, and the great kindness of the Arabs, especially Mohamad Bogharib, who had certainly saved his life.  Then he complains of the robbery of his goods, chiefly by one Musa bin Salim, one of the people of the Governor of Unyanyembe, who had bought ivory with the price, and another man who had bought a wife.  Livingstone does not expect his cloth and beads to be brought back, or the price of the wife and ivory returned, but he says: 

“I beg the assistance of your authority to prevent a fresh stock of goods, for which I now send to Zanzibar, being plundered in the same way.  Had it been the loss of ten or twelve pieces of cloth only, I should not have presumed to trouble your Highness about the loss; but 62 pieces or gorahs out of 80, besides beads, is like cutting a man’s throat.  If one or two guards of good character could be sent by you, no one would plunder the pagasi next time.

“I wish also to hire twelve or fifteen good freemen to act as canoe-men or porters, or in any other capacity that may be required.  I shall be greatly obliged if you appoint one of your gentlemen who knows the country to select that number, and give them and their headman a charge as to their behavior.  If they know that you wish them to behave well it will have great effect.  I wish to go down Tanganyika, through Luanda and Chowambe, and pass the river Karagwe, which falls into Lake Chowambe.  Then come back to Ujiji, visit Manyuema and Rua, and then return to Zanzibar, when I hope to see your Highness in the enjoyment of health and happiness.”

Livingstone showed only his usual foresight in taking these precautions for the protection of his next cargo of goods.  In stating so plainly his intended route, his purpose was doubtless to prevent carelessness in executing his orders, such as might have arisen had it been deemed uncertain where he was going, and whether or not he meant to return by Zanzibar.

Of letters during the latter part of this period very few seem to have reached their destination.  A short letter to Dr. Moffat, bearing date “Near Lake Moero, March, 1868,” dwells dolefully on his inability to reach Lake Bemba in consequence of the flooded state of the country, and then his detention through the strifes of the Arabs and the natives.  The letter, however, is more occupied with reviewing the past than narrating the present.  In writing to Dr. Moffat, he enters more minutely than he would have done with a less intimate and sympathetic friend into the difficulties of his lot—­difficulties that had been increased by some from whom he might have expected other things.  He had once seen a
