On returning, their former pursuers tried to induce them to come on shore.
Four days passed before Dr Livingstone with two of his party discovered them. He had in the mean time fallen in with the Mazitu, who were armed with spears and shields, and their heads fantastically dressed with feathers. By his usual courage and determination he prevented them from attacking him. When they demanded presents, he told them his goods were in the boat; and when they insisted on having a coat, the Makololo enquired how many of the party they had killed, that they thus began to divide the spoil; and at last, suspecting that he had support at hand, they took to their heels.
Numerous elephants, surprisingly tame, were seen on the borders of the lake even close to the villages, and hippopotami swarmed in all the creeks and lagoons. Several were shot for food during the journey. Sometimes food was thus abundant; at others, a few sardines served for dinner.
The slave trade on the lake was being pursued with fearful activity. A dhow had been built by two Arabs, who were running her regularly, crowded with slaves, across its waters. Part of the captives are carried to the Portuguese slave-exporting town of Iboe, while others go to Kilwa.
The chiefs showed but little inclination to trade, their traffic being chiefly in human chattels.
Colonel Rigby states that nineteen thousand slaves from the Nyassa country alone pass annually through the custom-house at Zanzibar.
They, however, represent but a small portion of the sufferers. Besides those actually captured, thousands are killed and die of their wounds and famine; thousands more perish in internecine war waged for slaves with their own clansmen and neighbours. The numerous skeletons seen among rocks and woods, by the pools, and on the paths of the wilderness, attest the awful sacrifice of human life.
The doctor saw that a small armed steamer on Lake Nyassa could, by furnishing goods in exchange for ivory and other products, exercise a powerful influence in stopping the traffic in that quarter.
The expedition had spent from the 2nd of September to the 27th of October in exploring the lake, and their goods being now expended, it was necessary to return to the ship.
On their way back they fell in with a number of Manjanga families, driven from their homes by Ajawa raids, taking shelter among the papyrus growing on Lake Pamalombe, supporting themselves on the fine fish which abound in it.
