At this moment the men announced that everything was ready for our ascent, and when I had attended to Joshua with a heart made thankful by Higgs’s news, we began that toilsome business, and, as I have already said, at length accomplished it safely. But even then our labours were not ended, since it was necessary to fill up the mouth of the shaft so as to make it impossible that it should be used by the Fung, who now knew of its existence.

Nor was this a business that could be delayed, for as we passed the plateau whence Oliver and Japhet had crossed to the sphinx, we heard the voices of men on the farther side of the rough wall that we had built there. Evidently the priests, or idol guards, infuriated by the rescue of their victim, had already managed to bridge the gulf and were contemplating assault, a knowledge which caused us to hurry our movements considerably. If they had got through before we passed them, our fate would have been terrible, since at the best we must have slowly starved in the pit below.

Indeed, as soon as we reached the top and had blocked it temporarily, Quick, weary as he was, was sent off on horseback, accompanied by Maqueda, Shadrach, now under the terms of his contract once more a free man, and two Mountaineers, to gallop to the palace of Mur, and fetch a supply of explosives. The rest of us, for Higgs declined to leave, and we had no means of carrying Joshua, remained watching the place, or rather the Abati watched while we slept with our rifles in our hands. Before noon Quick returned, accompanied by many men with litters and all things needful.

Then we pulled out the stones, and Oliver, Japhet, and some others descended to the first level and arranged blasting charges. Awhile after he reappeared with his companions, looking somewhat pale and anxious, and shouted to us to get back. Following our retreat to a certain distance, unwinding a wire as he came, presently he stopped and pressed the button of a battery which he held in his hand. There was a muffled explosion and a tremor of the soil like to that of an earthquake, while from the mouth of the shaft stones leapt into the air.

It was over, and all that could be noted was a sinkage in the ground where the ancient pit had been.

“I am sorry for them,” said Oliver presently, “but it had to be done.”

“Sorry for whom?” I asked.

“For those Fung priests or soldiers. The levels below are full of them, dead or alive. They were pouring up at our heels. Well, no one will travel that road again.”

Later, in the guest house at Mur, Higgs told us his story. After his betrayal by Shadrach, which, it appeared, was meant to include us all, for the Professor overheard the hurried talk between him and a Fung captain, he was seized and imprisoned in the body of the great sphinx, where many chambers and dungeons had been hollowed out by the primæval race that fashioned it. Here Barung the Sultan visited him and informed him of his meeting with the rest of us, to whom apparently he had taken a great liking, and also that we had refused to purchase a chance of his release at the price of being false to our trust.

“You know,” said Higgs, “that when first I heard this I was very angry with you, and thought you a set of beasts. But on considering things I saw the other side of it, and that you were right, although I never could come to fancy the idea of being sacrificed to a sphinx by being chucked like a piece of horse-flesh to a lot of holy lions. However, Barung, an excellent fellow in his way, assured me that there was no road out of the matter without giving grave offence to the priests, who are very powerful among the Fung, and bringing a fearful curse on the nation.
