“No.”
“And one can’t see down in this dark gash,” grumbled the man. “We humans are worse off than any of the animals. We can’t see so well, nor hear so well, nor smell so well, nor run, nor fly. Lucky for us, we’ve got gumption enough to make telescopes and steam-engines and ships, or I don’t know what we should do.”
“Who’s that?” said the colonel, returning. “Cyril?”
“Yes, sir.”
“Go and stand at the mouth of the cave, and mind that the mules don’t come out.”
Cyril obeyed, and took up his position on a stone in the gurgling stream, to stand listening to the soft patter of the mules within, and to the faint whispers which came time after time from where he had left the colonel and John Manning.
He had been at his position for some few minutes, turning from time to time in the darkness to cast a furtive look back into the entrance of the cavern, hardly able to restrain a shudder, as he thought of its unknown depths and the strange sound they had heard of the stone falling, and he could not help wishing that Perry was with him for company’s sake.
For there was a terrible feeling of lonesomeness there in the darkness, especially at a time like that, when he had just been roused from an uneasy sleep by something unexplained at which the colonel had taken alarm.
“He said either Indian or wild beast,” mused the boy. “What wild beast could there be?” There were, he knew, the wild varieties of the llamas, guanacoes, and the like, but they were timid, sheep-like creatures; and there were, he knew, pumas, the South American lions, as they were called, and perhaps jaguars—both these latter cat-like, nocturnal creatures; but they were animals of the forests, and not of these sterile, rocky valleys. Still, there might be other dangerous beasts in plenty, and his eyes wandered here and there, and he held his gun ready, though in that deep gloom he felt that he would be quite at the mercy of anything which attacked.
He had just reached this point, when his thoughts took a fresh direction—suppose some savage creature should be in the cave, and suddenly spring upon him from behind.
