The Sunbird

- and they began to disappear.

It was an astonishing phenomenon, sixty monkeys went into the tree and dwindled swiftly until the branches were deserted. Not a single monkey was left.

‘What happened to them?’ whispered Sally. ‘Did they go up the cliff?’

‘No, I don’t think so.’ I turned to her grinning happily. I think we’ve found it, Sal. I think this is it, but let’s just wait for the monkeys to come back.‘

Twenty minutes later the monkeys suddenly began reappearing in the branches of the wild fig again. The troop moved off in a leisurely fashion along the cliff, and we waited until they were all out of sight before we went forward.

The convoluted and massed roots of the wild fig formed a flight of irregular steps up towards the point where the trunk emerged from the cliff. We climbed up and began examining the trunk, working our way around it. peering up into the branches high overhead. The trunk was gigantic, fully thirty feet around, deformed and flattened by its contact with the uneven wall of red rock. Even then we might have missed it, had there not been a smoothly polished footpath leading into the living rock - a path worn by the passage of feet and paws and hooves over the course of thousands of years. The path squeezed between the gross yellow trunk of the wild fig, and the wall of rock. In the same manner there is often a cave behind a waterfall hidden by the falling water, so our wild fig screened the entrance.

Sally and I peered into the darkened recess behind the trunk, and then we looked at each other. Her eyes were sparkling bright and her cheeks flushed a dull rose.

‘Yes!’ she whispered, and I nodded, unable to speak.

‘Come on!’ She took my hand and we went in.

The opening was a long vertical crack in the cliff and good light came in from high above. Looking up I saw how the rock was polished by the paws of the monkeys who came in that way.

We moved on down the passage, the wall rising twenty feet on each side of us to a narrow vee of a roof. Immediately it was clear that we were not the first human beings that had entered here. The smooth red walls were covered with a profusion of magnificent bushman rock paintings. The most beautiful and well preserved that I had ever seen.

‘Ben! Oh Ben! Just look at them!’ One of Sally’s specialities is bushman art. ‘It’s a treasure house. Oh, you wonderful clever man!’ Her eyes shone in the gloom like lamps.

‘Come on!’ I tugged at her hand ‘There will be plenty of time for that later.’

We moved slowly along the narrow passage as it slanted steadily downwards for another hundred feet. The roof above us climbed progressively higher, until it was lost in the gloom above. We heard the squeak of bats from the dark recesses of the passage.

‘There is light ahead,’ I said, and we went on into an open chamber, rounded, perhaps 300 feet across with sheer walls which rose 200 feet upwards. Like the interior walls of a cone, they narrowed into a small aperture high above which gave a view of cloudless blue sky beyond.

I saw immediately that this was an intrusion of limestone into the red sandstone, and that it was a typical sink-hole formation, very similar to the Sleeping Pool at Sinoia in Rhodesia.

Here also the floor of the cavern was a basin which led down to a pool of water. The water was crystal clear, obviously very deep as the pale greenish colour showed, perhaps 150 feet across, the surface mirror-smooth and still.

Sally and I stood and stared at it. The beauty of this great cavern had paralysed us. Through the tiny aperture 200 feet above us the sun’s rays poured in like the beam of a searchlight, striking the walls of shimmering limestone and lighting the entire cavern with an eerie reflected glow. From the arched roof and walls hung great butterfly wings and stalactites of sparkling white.

The walls of the main chamber were also decorated to a height of fifteen feet or more with the lovely bushman art. In places water seeping from the rock had destroyed the graceful figures and designs, but mostly it was well preserved. I guessed there was two years’ work for Sally and me in this wondrous place.

Slowly she disengaged her hand from mine and walked down to the edge of the emerald pool. I stayed where I was in the mouth of the tunnel, watching her with rapt attention as she stood at the edge of the pool and leaned forward to peer down into the still water.

Then she straightened and slowly, with deliberate movements, began to strip off her clothing. She stood naked at the edge of the pool and her skin was as pale and translucent as the limestone cliffs. Her body, for all its size and strength, had a delicacy of line and texture to it that reminded me of the Chinese carvings in old ivory.

Like a priestess of some old pagan religion, she stood beside the pool and lifted her arms. With a strange atavistic thrill this gesture brought to my mind an ancient forgotten ritual. There was something deep in me that I wanted to cry out, a blessing perhaps, or an invocation.

Then she dived, a long graceful curve of white body and flowing dark hair. She struck the water and went on down, deep. The sweet clean shape of her showed clearly through the crystal water, then she came up slowly from the depths and broke the surface. Her long dark hair was slicked down over her neck and shoulders, she lifted one slender arm and waved at me.

I felt like crying out aloud with relief. I realized then that I had not expected her to come up again from those mysterious green depths. I went down to the edge of the pool to help her out of the water.

Presently we moved slowly around the walls of the cavern and passage, awed by the profusion of paintings and engravings, Sally with her damp hair hanging to her shoulders and her face shining with wonder.

‘There is work here spread over 2,000 years, Ben. This must have been a very holy place to the little yellow men.’ The light failed before we had completed half the tour of the cavern, and it was chilly and scary in the passage as we groped our way out. It was only then that I realized we had not eaten that day.

While Sally warmed up a hash of bully beef and onions, I raised Peter Larkin on the radio and was relieved to hear that the two trucks had returned safely to Maun. I ended the transmission by asking Larkin to get a message through to Louren. ‘Tell him we have found some very interesting rock paintings and
