On the journey south a minute inspection of the west coast was made and friendly relations cemented with the Chiefs. They all complained of the Ngoni who raided them unceasingly and carried off their cattle and grain, and they asked for war medicine to make their people strong and brave in battle. The Doctor disclaimed possessing any potion to impart courage that lay in a brave heart. ‘We will give you cattle and ivory for it,’ the Chiefs persisted. ‘But we really haven’t any’ Nothing would convince them. ‘You do not want to part with it,’ they said reproachfully. One old Chief thought he would put the matter to the test. He asked the Doctors to meet him secretly outside a village at the dead of night, and when they came pointed to a young bull, tethered to a tree, and a tusk of ivory on the ground. ‘I will give you those for your war medicine,’ he said.
Some Ngoni who had forsaken their tribe were discovered, and Dr. Laws asked Koyi to talk with them. They understood him at once. Procuring his New Testament he read the story of the Prodigal Son. The Doctor watched their faces, and saw that they took in the meaning. Koyi spoke of his, and their, old country, and told them how he had been with the English and had learned to love God and read His Book, and was now on the Lake as one of His teachers. They were deeply interested, and said they would endeavour to spread the news to the hills. The Doctor was more than ever convinced of the possibility of evangelizing these people by natives who knew their language.
