They bore down on the running elephant. Leon saw that they were all old bulls and at least two carried tusks of more than a hundred pounds a side. Another had only a single, the other broken off at the lip, but the remaining one was colossal and dwarfed those of his companions. Otto dropped lower, then lower still, until it looked as though he meant to fly straight into the herd. The elephant seemed to realize that they could not outrun the
Graf Otto climbed several hundred feet above the ground and flew on southwards. New and unexpected vistas opened before them. They flew over hidden valleys, secret re-entrants and salients in the walls of the Rift, some of which were not reflected on any survey map Leon had ever studied. Two or three valleys were fed by streams and pastured with green grass on which herds of large mammals, from giraffe to rhinoceros, had congregated. Leon tried to memorize the exact location of each one so that he could return to explore them, but they were flying so fast he found it difficult to keep track of their progress.
They climbed higher still until they could make out the vast massif of Kilimanjaro looming on the southern horizon a hundred miles or more ahead. The mountain was blue with distance, its crest wreathed in silver cloud through which the sun threw golden blades of light. Then Graf Otto waggled the wings to attract Leon’s attention and pointed out a closer mountain, only twenty or thirty miles off. The table top was unmistakable, and was probably what had attracted his notice.
‘Lonsonyo Mountain!’ Leon cried, but his voice was lost in the roar of wind and engines. ‘Go there!’ He made vehement hand signals, and Graf Otto opened the throttles wide. The
Before them, Lusima’s cattle were spread out as they grazed on the sweet grasses of the high table land. Beyond them Leon picked out the pattern of the huts and cattle pens that formed the
‘Lusima!’ Leon yelled, and ripped off his helmet and goggles. ‘Lusima Mama! It is me! M’bogo, your son!’ He waved frantically and suddenly she recognized him. He was so close that he saw her face light up and she waved with both hands, but then they were past and dropping down the far side of the mountain.
Once again Graf Otto waggled the wings and, with hand signals, asked Leon to point out the course he should take to reach the hunting camp. They had left it on the far side of Lonsonyo Mountain, so Leon directed him into a right-hand circuit of the sheer cliffs below the table land. He had never seen this side of the mountain before. Up until now, he had always approached and ascended from the southern side.
The rock was as sheer and impregnable as the outer wall of some monumental medieval fortress and lichen had painted on it a patchwork of many colours. Then, unexpectedly, the
