My first care was to explore the way I had come. I ran down the passage to the chasm which the slab of stone had spanned. I had been right in my guess, for the thing was gone. Laputa was in truth a Titan, who in the article of death could break down a bridge which would have taken any three men an hour to shift. The gorge was about seven yards wide, too far to risk a jump, and the cliff fell sheer and smooth to the imprisoned waters two hundred feet below. There was no chance of circuiting it, for the wall was as smooth as if it had been chiselled. The hand of man had been at work to make the sanctuary inviolable. It occurred to me that sooner or later Arcoll would track Laputa to this place. He would find the bloodstains in the gully, but the turnstile would be shut and he would never find the trick of it. Nor could he have any kaffirs with him who knew the secret of the Place of the Snake. Still if Arcoll knew I was inside he would find some way to get to me even though he had to dynamite the curtain of rock. I shouted, but my voice seemed to be drowned in the roar of the water. It made but a fresh chord in the wild orchestra, and I gave up hopes in that direction. Very dolefully I returned to the cave. I was about to share the experience of all treasure-hunters—to be left with jewels galore and not a bite to sustain life. The thing was too commonplace to be endured. I grew angry, and declined so obvious a fate. “Ek sal ’n plan maak,” I told myself in the old Dutchman’s words. I had come through worse dangers, and a way I should find. To starve in the cave was no ending for David Crawfurd. Far better to join Laputa in the depths in a manly hazard for liberty. My obstinacy and irritation cheered me. What had become of the lack-lustre young fool who had mooned here a few minutes back. Now I was as tense and strung for effort as the day I had ridden from Blaauwildebeestefontein to Umvelos’. I felt like a runner in the last lap of a race. For four days I had lived in the midst of terror and darkness. Daylight was only a few steps ahead, daylight and youth restored and a new world. There were only two outlets from that cave—the way I had come, and the way the river came. The first was closed, the second a sheer staring impossibility. I had been into every niche and cranny, and there was no sign of a passage. I sat down on the floor and looked at the wall of water. It fell, as I have already explained, in a solid sheet, which made up the whole of the wall of the cave. Higher than the roof of the cave I could not see what happened, except that it must be the open air, for the sun was shining on it. The water was about three yards distant from the edge of the cave’s floor, but it seemed to me that high up, level with the roof, this distance decreased to little more than a foot.
