Mr and Mrs Farquar were flustered and pleased and flattered. They asked the scientist to lunch, and they told the story all over again, for the hundredth time. Little Teddy was there too, his blue eyes sparkling with health, to prove the truth of it. The scientist explained how humanity might benefit if this new drug could be offered for sale; and the Farquars were even more pleased: they were kind, simple people, who liked to think of something good coming about because of them. But when the scientist began talking of the money that might result, their manner showed discomfort. Their feelings over the miracle (that was how they thought of it) were so strong and deep and religious, that it was distasteful to them to think of money. The scientist, seeing their faces, went back to his first point, which was the advancement of humanity. He was perhaps a trifle perfunctory: it was not the first time he had come salting the tail of a fabulous bush-secret.

Eventually, when the meal was over, the Farquars called Gideon into their living-room and explained to him that this baas, here, was a Big Doctor from the Big City, and he had come all that way to see Gideon. At this Gideon seemed afraid; he did not understand; and Mrs Farquar explained quickly that it was because of the wonderful thing he had done with Teddy's eyes that the Big Baas had come.

Gideon looked from Mrs Farquar to Mr Farquar, and then at the little boy, who was showing great importance because of the occasion. At last he said grudgingly: 'The Big Baas wants to know what medicine I used? He spoke incredulously, as if he could not believe his old friends could so betray him. Mr Farquar began explaining how a useful medicine could be made out of the root, and how it could be put on sale, and how thousands of people, black and white, up and down the continent of Africa, could be saved by the medicine when that spitting snake filled their eyes with poison. Gideon listened, his eyes bent on the ground, the skin of his forehead puckering in discomfort. When Mr Farquar had finished he did not reply. The scientist, who all this time had been leaning back in a big chair, sipping his coffee and smiling with sceptical good humour, chipped in and explained all over again, in different words, about the making of drugs and the progress of science. Also, he offered Gideon a present.

There was silence after this further explanation, and then Gideon remarked indifferently that he could not remember the root. His face was sullen and hostile, even when he looked at the Farquars, whom he usually treated like old friends. They were beginning to feel annoyed; and this feeling annulled the guilt that had been sprung into life by Gideon's accusing manner. They were beginning to feel that he was unreasonable. But it was at that moment that they all realized he would never give in. The magical drug would remain where it was, unknown and useless except for the tiny scattering of Africans who had the knowledge, natives who might be digging a ditch for the municipality in a ragged shirt and a pair of patched shorts, but who were still born to healing, hereditary healers, being the nephews or sons of the old witch doctors whose ugly masks and bits of bone and all the uncouth properties of magic were the outward signs of real power and wisdom.

The Farquars might tread on that plant fifty times a day as they passed from house to garden, from cow kraal to mealie field, but they would never know it.

But they went on persuading and arguing, with all the force of their exasperation; and Gideon continued to say that he could not remember, or that there was no such root, or that it was the wrong season of the year, or that it wasn't the root itself, but the spit from his mouth that had cured Teddy's eyes. He said all these things one after another, and seemed not to care they were contradictory. He was rude and stubborn. The Farquars could hardly recognize their gentle, lovable old servant in this ignorant, perversely obstinate African, standing there in front of them with lowered eyes, his hands twitching his cook's apron, repeating over and over whichever one of the stupid refusals that first entered his head.
