Livingstone now continued his perilous journey with his hundred men along the Zambesi, the country once densely populated, now desolate and still. The Bakota tribes, "the colour of coffee and milk," were friendly, and "great numbers came from all the surrounding villages and expressed great joy at the appearance of a white man and harbinger of peace." They brought in large supplies of food, and expressed great delight when Livingstone doctored their children, who were suffering from whooping-cough. As they neared the coast, they became aware of hostile forces. This was explained when they were met by a Portuguese half-caste "with jacket and hat on," who informed them that for the last two years they had been fighting the natives. Plunging thus unconsciously into the midst of a Kafir war rendered travelling unpleasant and dangerous. In addition, the party of explorers found their animals woefully bitten by the tsetse fly, rhinoceroses and elephants were too plentiful to be interesting, and the great white ant made itself tiresome. It was 3rd March before Livingstone reached Tete, two hundred and sixty miles from the coast. The last stages of the journey had been very beautiful. Many of the hills were of pure white marble, and pink marble formed the bed of more than one of the streams. Through this country the Zambesi rolled down toward the coast at the rate of four miles an hour, while flocks of water-fowl swarmed upon its banks or flew over its waters. Tete was the farthest outpost of the Portuguese. Livingstone was most kindly received by the governor, but fever again laid him low, and he had to remain here for three weeks before he was strong enough to start for the last stage of his journey to the coast. He left his Makololos here, promising to return some day to take them home again. They believed in him implicitly, and remained there three years, when he returned according to his word. Leaving Tete, he now embarked on the waters of the Zambesi, high with a fourth annual rise, which bore him to Sena in five days. So swift is the current at times that twenty-four hours is enough to take a boat from Tete to Sena, whereas the return journey may take twenty days. "I thought the state of Tete quite lamentable," says Livingstone, but that of Sena was ten times worse. "It is impossible to describe the miserable state of decay into which the Portuguese possessions here have sunk."
