Meantime I was pulling myself up on the shelf, and loosening with one hand a boulder which overhung the pool.
'You have been repaid,' he said savagely. 'You will not die.'
'But my life is no use without liberty,' I said, working at the boulder till it lay loose in its niche.
He did not answer, being intent on examining the Collar to see if it had suffered any harm.
'I hope it isn't scratched,' I said. 'Henriques trod on it when I hit him.'
Laputa peered at the gems like a mother at a child who has had a fall. I saw my chance and took it. With a great heave I pulled the boulder down into the pool. It made a prodigious splash, sending a shower of spray over Laputa and the Collar.
In cover of it I raced up the shelf, straining for the shelter of the juniper tree.
A shot rang out and struck the rock above me. A second later I had reached the tree and was scrambling up the crack beyond it.
Laputa did not fire again. He may have distrusted his shooting, or seen a better way of it. He dashed through the stream and ran up the shelf like a klipspringer after me. I felt rather than saw what was happening, and with my heart in my mouth I gathered my dregs of energy for the last struggle.
You know the nightmare when you are pursued by some awful terror, and, though sick with fear, your legs have a strange numbness, and you cannot drag them in obedience to the will. Such was my feeling in the crack above the juniper tree. In truth, I had passed the bounds of my endurance. Last night I had walked fifty miles, and all day I had borne the torments of a dreadful suspense. I had been bound and gagged and beaten till the force was out of my limbs. Also, and above all, I had had little food, and I was dizzy with want of sleep.
My feet seemed leaden, my hands had no more grip than putty. I do not know how I escaped falling into the pool, for my head was singing and my heart thumping in my throat. I seemed to feel Laputa's great hand every second clawing at my heels.
I had reason for my fears. He had entered the crack long before I had reached the top, and his progress was twice as fast as mine. When I emerged on the topmost shelf he was scarcely a yard behind me. But an overhang checked his bulky figure and gave me a few seconds' grace. I needed it all, for these last steps on the shelf were the totterings of an old man. Only a desperate resolution and an extreme terror made me drag one foot after the other. Blindly I staggered on to the top of the ravine, and saw before me the Schimmel grazing in the light of the westering sun.
I forced myself into a sort of drunken run, and crawled into the saddle. Behind me, as I turned, I could see Laputa's shoulders rising over the edge. I had no knife to cut the knee-halter, and the horse could not stir.
Then the miracle happened. When the rope had gagged me, my teeth must have nearly severed it at one place, and this Laputa had not noticed when he used it as a knee-halter. The shock of my entering the saddle made the Schimmel fling up his head violently, and the rope snapped. I could not find the stirrups, but I dug my heels into his sides, and he leaped forward.
At the same moment Laputa began to shoot. It was a foolish move, for he might have caught me by running, since I had neither spurs nor whip, and the horse was hampered by the loose end of rope at his knee. In any case, being an indifferent shot, he should have aimed at the Schimmel, not at me; but I suppose he wished to save his charger. One bullet sang past my head; a second did my business for me. It passed over my shoulder, as I lay low in the saddle, and grazed the beast's right ear. The pain maddened him, and, rope-end and all, he plunged into a wild gallop. Other shots came, but they fell far short. I saw dimly a native or two - the men who had followed us - rush to intercept me, and I think a spear was flung. But in a flash we were past them, and their cries faded behind me.
I found the bridle, reached for the stirrups, and galloped straight for the sunset and for freedom.
