"How did I find the old man?"
"Just that he seemed very old, much too old to be at the Zambesi at his time of life."
"Didn't I find him lightheaded?"
"On the contrary, quite normal."
"Hadn't he spun me some queer yarns?"
"No; just told me of his gun and his accident with it."
"Well, as a matter of fact, he was off his head, and I really mustn't believe all he said. Oh dear, he had kept them both in fits of laughter on the road up with his queer notions. Stories of gold mines and suchlike nonsense. Hadn't he talked of that kind of thing?"
"No."
"Well, he was now in bed with a go of fever and talking queerer than usual. Yes, if I could spare it, they'd like some quinine for him; but they had better be going, for it wasn't playing the game to leave an old man for long who had the fever on him."
The pair got up to go.
