This business proving unprofitable was not long continued. The Blacks retired again for consultation the result of which was that more than a dozen soon lighted brands at our smouldering fires and threw these in upon us as they darted by the opening of the cavern. No serious injury came from this. Our fellows would have flung these fiery spears back again, had I not restrained the action. The branches, it occurred to me, made torches too good to sacrifice for nothing. I therefore extinguished a number and kept several lighted. These latter we passed to the rear, in order that our positions might not be revealed to the foe. This throwing in of fire was concluded abruptly when the giant chief, watching his opportunity, sprang out, as one of the Blacks was running by, and battered in his head with the gleaming club. The rage of the assailants increased momentarily. They saw themselves baffled by a force inferior to their own, although they had us cornered. With no little anxiety, we watched them detach a company of powerful fighters and send them off out of sight. This could not indicate retreat, I knew, for the ones who were left were too expectant. Perhaps, I thought, this was a blind to make us believe the force was now so reduced that we could charge them from the cave in safety and drive the invaders from the camp. There were, indeed, a few in our party, as I could see, who desired to attempt such a sortie, but fortunately the chief and other wise fellows over-ruled the suggestion. While we were waiting, restless and worried, the plan of the Blacks was suddenly revealed. Amid yells of triumph and hatred, there came a thundering shower of rocks and boulders from directly above the cave, falling down across its mouth, heaping rapidly up, filling the place with a stifling dust and obliterating much of the light of day. The party detached had gone around and climbed on top of the terrace in which the cave was hollowed out. It would simply have been to court a sudden death had any of us attempted to dash from the place. Startled, undecided as to what we ought to do, we stood there paralysed, while the bewildering Niagara of sand and stone kept rumbling and crashing down. Before we realised what was occurring, the barrier had grown to a heap that was midway up across the opening of the hole. There were strange cries, roars and howlings, from those behind us. Above the din rose the piercing screams of delight from the horde without. All of them now rushed to the spot in a body and began to heap up all the stones they could gather. Blinded, confused and frightened, my friendly Links began to jostle about, in the dread and anguish of the doomed. In less than five minutes the last rays of light were being blotted out. The sounds of the army still building the barrier higher and thicker came dully in. The cave was sealed; we were buried alive in an unknown tomb!
