“My heart was moved when I saw him. I knew him to be of my own people, but I dared not believe that he was the child I loved, and whom I had lost so long ago. White man, I will load your waggon with tusks. You shall take them to the good missionary chief who has sent me back my boy; or if he will come here with a waggon himself, he and his people shall be fed as long as they will remain.”

Thus the father endeavoured to express his gratitude to the missionary who had preserved his son, and to those who had brought him back. Mr Vincent, however, did not put full confidence in his promises. He replied that he should be happy to convey his messages to the missionary; but that as he had come to trade, he must purchase tusks for himself, though he would carry as many as he had room for, if sent as a present.

The chief offered to convey the trader’s goods over the river, and to float the waggon across it, while the cattle and horses would pass over by swimming, to his village. This was accomplished the next day. Kanenge appropriated several huts for the accommodation of his visitors, in one of which they took up their residence, in another their goods were stored, while their attendants inhabited the remainder.

Trade was now commenced, and everything appeared to be going on prosperously. Scarcely, however, had these arrangements been made than Masiko and their driver came with the intelligence that several of the oxen were sickening from the effects of the tsetse-bites. No cure was known. The most healthy had already perished. In a few days it was found that all the cattle, as well as the horses, had been bitten by the deadly insect.

Martin tried to console his father by pointing out how much worse it would have been had they perished on the journey, in which case the waggon and its contents must have been deserted, and they themselves would in all probability have lost their lives. The trader, however, was inclined to look at things in a gloomy light.

Though fresh oxen might be procured in the country, it would require some time to break them in, while their cost would swallow up a considerable portion of his profits.

Mr Vincent himself was ill, and in a few days he was attacked with fever, while several of his men were suffering from the same complaint.

Martin now felt thankful that he had accompanied his father, and while he attended him with the most devoted care, he did his utmost to take his place in carrying on trade with the natives. His father appeared well pleased with the way he transacted business, when he each day reported the progress he had made, and gradually their store-hut became filled with elephant-tusks.

“Ah, Martin, you will become a first-rate trader,” he observed; “and I hope we shall soon recover our losses. As soon as I am well we must push further to the eastward, where I hear there are large supplies of ivory. In the meantime we must get fresh oxen broken in.”

“I am thankful to be able to assist you, father,” answered Martin; “but I must not pride myself on my dealings with the natives. We are now with a friendly chief who treats us fairly, but I understand the people among whom you propose going are likely to behave in a very different way; besides which, the country is exposed to the inroads of hostile tribes, and should they hear that such a prize as our waggon full of goods is in the neighbourhood, they will attack us in the hopes of carrying it off.”
