In fulfillment of a promise made to the natives in the interior that he would return to them, Livingstone set out on a second tour into the interior of the Bechuana country on 10th February, 1842. His objects were, first, to acquire the native language more perfectly, and second, by suspending his medical practice, which had become inconveniently large at Kuruman, to give his undivided attention to the subject of native agents. He took with him two native members of the Kuruman church, and two other natives for the management of the wagon.
The first person that specially engaged his interest in this journey was a chief of the name of Bubi, whose people were Bakwains. With him he stationed one of the native agents as a teacher, the chief himself collecting the children and supplying them with food. The honesty of the people was shown in their leaving untouched all the contents of his wagon, though crowds of them visited it. Livingstone was already acquiring a powerful influence, both with chiefs and people, the result of his considerate and conciliatory treatment of both. He had already observed the failure of some of his brethren to influence them, and his sagacity had discerned the cause. His success in inducing Bubi's people to dig a canal was contrasted in a characteristic passage of a private letter, with the experience of others.
"The doctor and the rainmaker among these people are one and the same person. As I did not like to be behind my professional brethren, I declared I could make rain too, not, however, by enchantments like them, but by leading out their river for irrigation. The idea pleased mightily, and to work we went instanter. Even the chief's own doctor is at it, and works like a good fellow, laughing heartily at the cunning of the 'foreigner' who can make rain so. We have only one spade, and this is without a handle; and yet by means of sticks sharpened to a point we have performed all the digging of a pretty long canal. The earth was lifted out in 'gowpens' and carried to the huge dam we have built in karosses (skin cloaks), tortoise-shells, or wooden bowls. We intended nothing of the ornamental in it, but when we came to a huge stone, we were forced to search for a way round it. The consequence is, it has assumed a beautifully serpentine appearance. This is, I believe, the first instance in which Bechuanas have been got to work without wages. It was with the utmost difficulty the earlier missionaries got them to do anything. The missionaries solicited their permission to do what they did, and this was the very way to make them show off their airs, for they are so disobliging; if they perceive any one in the least dependent upon them, they immediately begin to tyrannize. A more mean and selfish vice certainly does not exist in the world. I am trying a different plan with them. I make my presence with any of them a favor, and when they show any impudence, I threaten to leave them, and if they don't amend, I put my threat into execution. By a bold, free course among them I have had not the least difficulty in managing the most fierce. They are in one sense fierce, and in another the greatest cowards in the world. A kick would, I am persuaded, quell the courage of the bravest of them. Add to this the report which many of them verily believe, that I am a great wizard, and you will understand how I can with ease visit any of them. Those who do not love, fear me, and so truly in their eyes am I possessed of supernatural power, some have not hesitated to affirm I am capable of even raising the dead! The people of a village visited by a French brother actually believed it. Their belief of my powers, I suppose, accounts, too, for the fact that I have not missed a single article either from the house or wagon since I came among them, and this, although all my things lay scattered about the room, while crammed with patients."
