chunk: Colonel John Patterson is to build a bridge in East Africa (later Kenya). While he is working on this, two man-eating lions show up. They will stop at nothing for a bite of human flesh and the first attempts to stalk, capture or keep them out of the camp fail. They attack the camp hospital and kill a patient. Even after the hospital is moved, one lion penetrates the thick, thorn fence called a boma built to protect it and drags the water carrier away to his death. In the course of hunting these lions, Patterson encounters a red spitting cobra, a rhinoceros, a hippopotamus, a pack of wild dogs, a wildebeest that faked dying, and a herd of zebra, of which he captured six. He also shoots a new type of antelope, T. oryx pattersonianus. Eventually, the first lion is defeated by baiting it with a tethered goat while Patterson keeps watch from an elevated stand â though for a few tense moments Patterson himself becomes the hunted. Patterson and Mahina hunt the second lion on the plains.
