“There’s nothing else to do,” groaned Bastin.
The great stone appeared and, as before, hung at the edge of the pit. Yva stepped on to it quietly, as she did so, catching hold of my wrist with her disengaged hand. I followed her feeling very sick, and promptly sat down. Then came Bickley with the air of the virtuous hero of a romance walking a pirate’s plank, and also sat down. Only Bastin hesitated until the stone began to move away. Then with an ejaculation of “Here goes!” he jumped over the intervening crack of space and landed in the middle of us like a sack of coal. Had I not been seated really I think he would have knocked me off the rock. As it was, with one hand he gripped me by the beard and with the other grasped Yva’s robe, of neither of which would he leave go for quite a long time, although we forced him on to his face. The lantern which he held flew from his grasp and descended the shaft on its own account.
“You silly fool!” exclaimed Bickley whose perturbation showed itself in anger. “There goes one of our lamps.”
“Hang the lamp!” muttered the prostrate Bastin. “We shan’t want it in Heaven, or the other place either.”
Now the stone which had quivered a little beneath the impact of Bastin, steadied itself again and with a slow and majestic movement sailed to the other side of the gulf. There it felt the force of gravity, or perhaps the weight of the returning air pressed on it, which I do not know. At any rate it began to fall, slowly at first, then more swiftly, and afterwards at an incredible pace, so that in a few seconds the mouth of the pit above us grew small and presently vanished quite away. I looked up at Yva who was standing composedly in the midst of our prostrate shapes. She bent down and called in my ear:
“All is well. The heat begins, but it will not endure for long.”
I nodded and glanced over the edge of the stone at Bastin’s lantern which was sailing alongside of us, till presently we passed it. Bastin had lit it before we started, I think in a moment of aberration, and it burned for quite a long while, showing like a star when the shaft grew darker as it did by degrees, a circumstance that testifies to the excellence of the make, which is one advertised not to go out in any wind. Not that we felt wind, or even draught, perhaps because we were travelling with it.
Then we entered the heat zone. About this there was no doubt, for the perspiration burst out all over me and the burning air scorched my lungs. Also Tommy thrust his head from beneath the cloak with his tongue hanging out and his mouth wide open.
“Hold your breaths!” cried Yva, and we obeyed until we nearly burst. At least I did, but what happened to the others I do not know.
Fortunately it was soon over and the air began to grow cool again. By now we had travelled an enormous distance, it seemed to be miles on miles, and I noticed that our terrific speed was slackening, also that the shaft grew more narrow, till at length there were only a few feet between the edge of the stone and its walls. The result of this, or so I supposed, was that the compressed air acted as a buffer, lessening our momentum, till at length the huge stone moved but very slowly.
“Be ready to follow me,” cried Yva again, and we rose to our feet, that is, Bickley and I did, but poor Bastin was semi-comatose. The stone stopped and Yva sprang from it to a rock platform level with which it lay. We followed, dragging Bastin between us. As we did so something hit me gently on the head. It was Bastin’s lamp, which I seized.
“We are safe. Sit down and rest,” said Yva, leading us a few paces away.
We obeyed and presently by the dim light saw the stone begin to stir again, this time upwards. In another twenty seconds it was away on its never-ending journey.
“Does it always go on like that?” said Bastin, sitting up and staring after it.
“Tens of thousands of years ago it was journeying thus, and tens of thousands of years hence it will still be journeying, or so I think,” she replied. “Why not, since the strength of the draught never changes and there is nothing to wear it except the air?”
Somehow the vision of this huge stone, first loosed and set in motion by heaven knows what agency, travelling from aeon to aeon up and down that shaft in obedience to some law I did not understand, impressed my imagination like a nightmare. Indeed I often dream of it to this day.
I looked about me. We were in some cavernous place that could be but dimly seen, for here the light that flowed down the shaft from the upper caves where it was mysteriously created, scarcely shone, and often indeed was entirely cut off, when the ever-journeying stone was in the narrowest parts of the passage. I could see, however, that this cavern stretched away both to right and left of us, while I felt that from the left, as we sat facing the shaft, there drew down a strong blast of fresh air which suggested that somewhere, however far away, it must open on to the upper world. For the rest its bottom and walls seemed to be smooth as though they had been planed in the past ages by the action of cosmic forces. Bickley noticed this the first and pointed it out to me. We had little time to observe, however, for presently Yva said:
“If you are rested, friends,
