"Anyway, we know now that they can raise that stone whenever they feel like it. But in the name of Archimedes, how?"
He advanced to the doorway and examined the block of granite curiously, but there was no clue to its weight or thickness from the inside. I explained that there were several ways by which the thing could be raised, but that the most probable one was by means of a rolling pulley, which required merely some rounded stones and a flat surface above, with ropes of hide for stays.
It had been several hours since we had last eaten, and we decided to at once convey to the spies without our intentions concerning our prisoner. So we regaled ourselves with dried fish and water, taking care not to approach the king, who had rolled over on his side and lay facing us, looking for all the world, in the dim light, like a black dog crouched on the floor.
Harry relieved me at my post against the door, and I lay down to sleep. Desiree had seated herself beside him, and the low tones of their voices came to me as I lay on the couch (which Desiree had insisted I should occupy) in an indistinct, musical murmur. This for perhaps ten minutes; then I slept.
That became our routine. During the many weary hours that followed there was never a moment when one of us was not seated with his back against the stone across the doorway; we dared not trust our eyes. Usually Harry and Desiree watched together, and, when I relieved them, slept side by side on the couch.
Sometimes, when we were all awake, Desiree was left on guard alone; but Harry and I were never both asleep at the same time.
An estimate of the time we spent thus would be the wildest guess, for time was heavy and passed on leaden feet. But I should say we had been imprisoned for something like four days, possibly five, when the monotony came to an abrupt end.
I had come off watch, and Harry and Desiree had taken my place. Before I lay down I had taken some water to the prisoner, for we had some time before admitted the necessity of giving him drink. But of food he had had none.
Harry told me afterward that I had slept for two or three hours, but it seemed to me rather as many minutes, when I was awakened by the sound of his voice calling my name. Glancing at the doorway, I sprang to my feet.
The stone was slowly rising from the floor; already there was a space of a foot or more. Desiree and Harry stood facing it in silence.
