As they proceeded, some of his old acquaintances reappeared, notably Mpende, who had given him such a threatening reception, but had now learned that he belonged to a tribe "that loved the black man and did not make slaves." A chief named Pangola appeared, at first tipsy and talkative, demanding a rifle, and next morning, just as they were beginning divine service, reappeared sober to press his request. Among the Baenda-Pezi, or Go-Nakeds, whose only clothing is a coat of red ochre, a noble specimen of the race appeared in full dress, consisting of a long tobacco-pipe, and brought a handsome present. The country bore the usual traces of the results of African warfare. At times a clever chief stands up, who brings large tracts under his dominion; at his death his empire dissolves, and a fresh series of desolating wars ensues. In one region which was once studded with villages, they walked a whole week without meeting any one. A European colony, he was sure, would be invaluable for constraining the tribes to live in peace. "Thousands of industrious natives would gladly settle round it, and engage in that peaceful pursuit of agriculture and trade of which they are so fond, and, undistracted by wars and rumors of wars, might listen to the purifying and ennobling truths of the gospel of Jesus Christ." At Zumbo, the most picturesque site in the country, they saw the ruins of Jesuit missions, reminding them that there men once met to utter the magnificent words, "Thou art the King of Glory, O Christ!" but without leaving one permanent trace of their labors in the belief and worship of the people. Wherever they go, Dr. Livingstone has his eye on the trees and plants and fruits of the region, with a view to commerce; while he is no less interested to watch the treatment of fever, when cases occur, and greatly gratified that Dr. Kirk, who had been trying a variety of medicines on himself, made rapid recovery when he took Dr. Livingstone's pills. He used to say if he had followed Morison, and set up as pill-maker, he might have made his fortune. Passing through the Bazizulu he had an escape from a rhinoceros, as remarkable though not quite as romantic as his escape from the lion; the animal came dashing at him, and suddenly, for some unknown reason, stopped when close to him, and gave him time to escape, as if it had been struck by his color, and doubtful if hunting a white man would be good sport. At a month's distance from Mosilikatse, they heard a report that the missionaries had been there, that they had told the chief that it was wrong to kill men, and that the chief had said he was born to kill people, but would drop the practice--an interesting testimony to the power of Mr. Moffat's words. Everywhere the Makololo proclaimed that they were the friends of peace, and their course was like a triumphal procession, the people of the villages loading them with presents.
