Sir Arthur Conan Doyle: The Lost World

Chapter 12: "It was Dreadful in the Forest" (continued)

The night had been exceedingly still, but as I advanced I became conscious of a low, rumbling sound, a continuous murmur, somewhere in front of me. This grew louder as I proceeded, until at last it was clearly quite close to me. When I stood still the sound was constant, so that it seemed to come from some stationary cause. It was like a boiling kettle or the bubbling of some great pot. Soon I came upon the source of it, for in the center of a small clearing I found a lake--or a pool, rather, for it was not larger than the basin of the Trafalgar Square fountain--of some black, pitch-like stuff, the surface of which rose and fell in great blisters of bursting gas. The air above it was shimmering with heat, and the ground round was so hot that I could hardly bear to lay my hand on it. It was clear that the great volcanic outburst which had raised this strange plateau so many years ago had not yet entirely spent its forces. Blackened rocks and mounds of lava I had already seen everywhere peeping out from amid the luxuriant vegetation which draped them, but this asphalt pool in the jungle was the first sign that we had of actual existing activity on the slopes of the ancient crater. I had no time to examine it further for I had need to hurry if I were to be back in camp in the morning.

It was a fearsome walk, and one which will be with me so long as memory holds. In the great moonlight clearings I slunk along among the shadows on the margin. In the jungle I crept forward, stopping with a beating heart whenever I heard, as I often did, the crash of breaking branches as some wild beast went past. Now and then great shadows loomed up for an instant and were gone--great, silent shadows which seemed to prowl upon padded feet. How often I stopped with the intention of returning, and yet every time my pride conquered my fear, and sent me on again until my object should be attained.
