Sound travels slowly, so it was some time before he heard an answering glibber. But it came at last, and before long he was told that a rope ladder would be lowered. The wait for this was very tense, since there was no telling what might not have been stirred up among those bones by his shouting. Indeed, it was not long before he actually did hear a vague rustling afar off. As this thoughtfully approached, he became more and more uncomfortable; for he did not wish to move away from the spot where the ladder would come. Finally the tension grew almost unbearable, and he was about to flee in panic when the thud of something on the newly heaped bones nearby drew his notice from the other sound. It was the ladder, and after a minute of groping he had it taut in his hands. But the other sound did not cease, and followed him even as he climbed. He had gone fully five feet from the ground when the rattling beneath waxed emphatic, and was a good ten feet up when something swayed the ladder from below. At a height which must have been fifteen or twenty feet he felt his whole side brushed by a great slippery length which grew alternately convex and concave with wriggling; and thereafter he climbed desperately to escape the unendurable nuzzling of that loathsome and overfed Dhole whose form no man might see.
