As soon as we had got some things together and shaken ourselves together a little, we set to work to make out where we were now. I have said that there was light above, and on examination we found that it came from the sky. Our rive that was, Sir Henry said, a literal realization of the wild vision of the poet {Endnote 10}, was no longer underground, but was running on its darksome way, not now through ‘caverns measureless to man’, but between two frightful cliffs which cannot have been less than two thousand feet high. So high were they, indeed, that though the sky was above us, where we were was dense gloom — not darkness indeed, but the gloom of a room closely shuttered in the daytime. Up on either side rose the great straight cliffs, grim and forbidding, till the eye grew dizzy with trying to measure their sheer height. The little space of sky that marked where they ended lay like a thread of blue upon their soaring blackness, which was unrelieved by any tree or creeper. Here and there, however, grew ghostly patches of a long grey lichen, hanging motionless to the rock as the white beard to the chin of a dead man. It seemed as though only the dregs or heavier part of the light had sunk to the bottom of this awful place. No bright-winged sunbeam could fall so low: they died far, far above our heads.
By the river’s edge was a little shore formed of round fragments of rock washed into this shape by the constant action of water, and giving the place the appearance of being strewn with thousands of fossil cannon balls. Evidently when the water of the underground river is high there is no beach at all, or very little, between the border of the stream and the precipitous cliffs; but now there was a space of seven or eight yards. And here, on this beach, we determined to land, in order to rest ourselves a little after all that we had gone through and to stretch our limbs. It was a dreadful place, but it would give an hour’s respite from the terrors of the river, and also allow of our repacking and arranging the canoe. Accordingly we selected what looked like a favourable spot, and with some little difficulty managed to beach the canoe and scramble out on to the round, inhospitable pebbles.
‘My word,’ called out Good, who was on shore the first, ‘what an awful place! It’s enough to give one a fit.’ And he laughed.
Instantly a thundering voice took up his words, magnifying them a hundred times. ‘Give one a fit — Ho! ho! ho!’ — ‘A fit, Ho! ho! ho!’ answered another voice in wild accents from far up the cliff — a fit! a fit! a fit! chimed in voice after voice — each flinging the words to and fro with shouts of awful laughter to the invisible lips of the other till the whole place echoed with the words and with shrieks of fiendish merriment, which at last ceased as suddenly as they had begun.
‘Oh, mon Dieu!’ yelled Alphonse, startled quite out of such self-command as he possessed.
‘Mon Dieu! Mon Dieu! Mon Dieu!’ the Titanic echoes thundered, shrieked, and wailed in every conceivable tone.
‘Ah,’ said Umslopogaas calmly, ‘I clearly perceive that devils live here. Well, the place looks like it.’
I tried to explain to him that the cause of all the hubbub was a very remarkable and interesting echo, but he would not believe it.
‘Ah,’ he said, ‘I know an echo when I hear one. There was one lived opposite my kraal in Zululand, and the Intombis [maidens] used to talk with it. But if what we hear is a full-grown echo, mine at home can only have been a baby. No, no — they are devils up there. But I don’t think much of them, though,’ he added, taking a pinch of snuff. ‘They can copy what one says, but they don’t seem to be able to talk on their own account, and they dare not show their faces,’ and he relapsed into silence, and apparently paid no further attention to such contemptible fiends.
