He staggered into a dark recess, one of many in the cave, and I followed him. There were boxes there, tea chests, cartridge cases, and old brass-ribbed Portuguese coffers.
Laputa had keys at his belt, and unlocked them, his fingers fumbling with weakness. I peered in and saw gold coin and little bags of stones.
'Money and diamonds,' he cried. 'Once it was the war chest of a king, and now it will be the hoard of a trader. No, by the Lord! The trader's place is with the Terrible Ones.' An arm shot out, and my shoulder was fiercely gripped.
'You stole my horse. That is why I am dying. But for you I and my army would be over the Olifants. I am going to kill you, Crawfurd,' and his fingers closed in to my shoulder blades.
Still I was unperturbed. 'No, you are not. You cannot. You have tried to and failed. So did Henriques, and he is lying dead outside. I am in God's keeping, and cannot die before my time.'
I do not know if he heard me, but at any rate the murderous fit passed. His hand fell to his side and his great figure tottered out into the cave. He seemed to be making for the river, but he turned and went through the door I had entered by. I heard him slipping in the passage, and then there was a minute of silence.
Suddenly there came a grinding sound, followed by the kind of muffled splash which a stone makes when it falls into a deep well. I thought Laputa had fallen into the chasm, but when I reached the door his swaying figure was coming out of the corridor. Then I knew what he had done. He had used the remnant of his giant strength to break down the bridge of stone across the gorge, and so cut off my retreat.
I really did not care. Even if I had got over the bridge I should probably have been foiled by the shut turnstile. I had quite forgotten the meaning of fear of death.
I found myself giving my arm to the man who had tried to destroy me.
'I have laid up for you treasure in heaven,' he said. 'Your earthly treasure is in the boxes, but soon you will be seeking incorruptible jewels in the deep deep water. It is cool and quiet down there, and you forget the hunger and pain.'
The man was getting very near his end. The madness of despair came back to him, and he flung himself among the ashes.
'We are going to die together, Crawfurd,' he said. 'God has twined our threads, and there will be only one cutting. Tell me what has become of my army.'
'Arcoll has guns on the Wolkberg,' I said. 'They must submit or perish.'
'I have other armies ... No, no, they are nothing. They will all wander and blunder and fight and be beaten. There is no leader anywhere ... And I am dying.'
There was no gainsaying the signs of death. I asked him if he would like water, but he made no answer. His eyes were fixed on vacancy, and I thought I could realize something of the bitterness of that great regret. For myself I was as cold as a stone. I had no exultation of triumph, still less any fear of my own fate. I stood silent, the half-remorseful spectator of a fall like the fall of Lucifer.
'I would have taught the world wisdom.' Laputa was speaking English in a strange, thin, abstracted voice. 'There would have been no king like me since Charlemagne,' and he strayed into Latin which I have been told since was an adaptation of the Epitaph of Charles the Great. 'Sub hoc conditorio,' he crooned, 'situm est corpus Joannis, magni et orthodoxi Imperatoris, qui imperium Africanum nobiliter ampliavit, et multos per annos mundum feliciter rexit.'* He must have chosen this epitaph long ago.
*'Under this stone is laid the body of John, the great and orthodox Emperor, who nobly enlarged the African realm, and for many years happily ruled the world.'
He lay for a few seconds with his head on his arms, his breast heaving with agony.
'No one will come after me. My race is doomed, and in a little they will have forgotten my name. I alone could have saved them. Now they go the way of the rest, and the warriors of John become drudges and slaves.'
Something clicked in his throat, he gasped and fell forward, and I thought he was dead. Then he struggled as if to rise. I ran to him, and with all my strength aided him to his feet.
'Unarm, Eros,' he cried. 'The long day's task is done.' With the strange power of a dying man he tore off his leopard-skin and belt till he stood stark as on the night when he had been crowned. From his pouch he took the Prester's Collar. Then he staggered to the brink of the chasm where the wall of green water dropped into the dark depth below.
I watched, fascinated, as with the weak hands of a child he twined the rubies round his neck and joined the clasp. Then with a last effort he stood straight up on the brink, his eyes raised to the belt of daylight from which the water fell. The light caught the great gems and called fires from them, the flames of the funeral pyre of a king.
Once more his voice, restored for a moment to its old vigour, rang out through the cave above the din of the cascade. His words were those which the Keeper had used three nights before. With his hands held high and the Collar burning on his neck he cried, 'The Snake returns to the House of its Birth.'
'Come,' he cried to me. 'The Heir of John is going home.'
Then he leapt into the gulf. There was no sound of falling, so great was the rush of water. He must have been whirled into the open below where the bridge used to be, and then swept into the underground deeps, where the Labongo drowses for thirty miles. Far from human quest he sleeps his last sleep, and perhaps on a fragment of bone washed into a crevice of rock there may hang the jewels that once gleamed in Sheba's hair.
