"Well, yer all givin up too soon," said Pat. "Come along now; there's lots of places yet to examin. Give one of yer loudest yells."
Captain Corbet did so. In spite of his despondency as to poor old Solomon's fate, he was not at all unwilling to try any further chances. On this occasion he seemed to gain unusual energy out of his very despair; and the yell that burst from him was so high, so shrill, so piercing, and so far penetrating, that the former cries were nothing compared to it.
"Well done!" cried Pat. "Sure an you bet yerself that time, out an out."
"Stop!" cried Phil. "Listen. What's that?"
Far away, as they listened, they heard a faint cry, that seemed like a response.
"Is that the echo?" asked Phil, anxiously.
"Niver an echo!" cried Pat, excitedly. "Shout agin, captain, darlin."
Captain Corbet gave another shout as loud and as shrill as the preceding one.
They listened anxiously.
Again they heard the cry. It was faint and far off; yet it was unmistakably a human cry. Their excitement now grew intense.
