I was roused by a sudden movement. The whole assembly stood up, and each man clapped his right hand to his brow and then raised it high. A low murmur of 'Inkulu' rose above the din of the water. Laputa strode down the hall, with Henriques limping behind him. They certainly did not suspect my presence in the cave, nor did Laputa show any ruffling of his calm. Only Henriques looked weary and cross. I guessed he had had to ride my pony.
The old man whom I took to be the priest advanced towards Laputa with his hands raised over his head. A pace before they met he halted, and Laputa went on his knees before him. He placed his hands on his head, and spoke some words which I could not understand. It reminded me, so queer are the tricks of memory, of an old Sabbath-school book I used to have which had a picture of Samuel ordaining Saul as king of Israel. I think I had forgotten my own peril and was enthralled by the majesty of the place - the wavering torches, the dropping wall of green water, above all, the figures of Laputa and the Keeper of the Snake, who seemed to have stepped out of an antique world.
Laputa stripped off his leopard skin till he stood stark, a noble form of a man. Then the priest sprinkled some herbs on the fire, and a thin smoke rose to the roof. The smell was that I had smelled on the Kirkcaple shore, sweet, sharp, and strange enough to chill the marrow. And round the fire went the priest in widening and contracting circles, just as on that Sabbath evening in spring.
Once more we were sitting on the ground, all except Laputa and the Keeper. Henriques was squatting in the front row, a tiny creature among so many burly savages. Laputa stood with bent head in the centre.
Then a song began, a wild incantation in which all joined.
The old priest would speak some words, and the reply came in barbaric music. The words meant nothing to me; they must have been in some tongue long since dead. But the music told its own tale. It spoke of old kings and great battles, of splendid palaces and strong battlements, of queens white as ivory, of death and life, love and hate, joy and sorrow. It spoke, too, of desperate things, mysteries of horror long shut to the world.
No Kaffir ever forged that ritual. It must have come straight from Prester John or Sheba's queen, or whoever ruled in Africa when time was young.
I was horribly impressed. Devouring curiosity and a lurking nameless fear filled my mind. My old dread had gone. I was not afraid now of Kaffir guns, but of the black magic of which Laputa had the key.
The incantation died away, but still herbs were flung on the fire, till the smoke rose in a great cloud, through which the priest loomed misty and huge. Out of the smoke-wreaths his voice came high and strange. It was as if some treble stop had been opened in a great organ, as against the bass drone of the cataract.
He was asking Laputa questions, to which came answers in that rich voice which on board the liner had preached the gospel of Christ. The tongue I did not know, and I doubt if my neighbours were in better case. It must have been some old sacred language - Phoenician, Sabaean, I know not what - which had survived in the rite of the Snake.
Then came silence while the fire died down and the smoke eddied away in wreaths towards the river. The priest's lips moved as if in prayer: of Laputa I saw only the back, and his head was bowed.
Suddenly a rapt cry broke from the Keeper. 'God has spoken,' he cried. 'The path is clear. The Snake returns to the House of its Birth.'
An attendant led forward a black goat, which bleated feebly.
With a huge antique knife the old man slit its throat, catching the blood in a stone ewer. Some was flung on the fire, which had burned small and low.
'Even so,' cried the priest, 'will the king quench in blood the hearth-fires of his foes.'
Then on Laputa's forehead and bare breast he drew a bloody cross.
'I seal thee,' said the voice, 'priest and king of God's people.'
The ewer was carried round the assembly, and each dipped his finger in it and marked his forehead. I got a dab to add to the other marks on my face.
'Priest and king of God's people,' said the voice again, 'I call thee to the inheritance of John. Priest and king was he, king of kings, lord of hosts, master of the earth. When he ascended on high he left to his son the sacred Snake, the ark of his valour, to be God's dower and pledge to the people whom He has chosen.'
I could not make out what followed. It seemed to be a long roll of the kings who had borne the Snake. None of them I knew, but at the end I thought I caught the name of Tchaka the Terrible, and I remembered Arcoll's tale.
The Keeper held in his arms a box of curiously wrought ivory, about two feet long and one broad. He was standing beyond the ashes, from which, in spite of the blood, thin streams of smoke still ascended. He opened it, and drew out something which swung from his hand like a cascade of red fire.
'Behold the Snake,' cried the Keeper, and every man in the assembly, excepting Laputa and including me, bowed his head to the ground and cried 'Ow.'
'Ye who have seen the Snake,' came the voice, on you is the vow of silence and peace. No blood shall ye shed of man or beast, no flesh shall ye eat till the vow is taken from you. From the hour of midnight till sunrise on the second day ye are bound to God. Whoever shall break the vow, on him shall the curse fall. His blood shall dry in his veins, and his flesh shrink on his bones. He shall be an outlaw and accursed, and there shall follow him through life and death the Avengers of the Snake. Choose ye, my people; upon you is the vow.'
By this time we were all flat on our faces, and a great cry of assent went up. I lifted my head as much as I dared to see what would happen next.
