"The Incas!" I gasped.
"They are gone," Harry answered.
At that I struggled to rise and rested my body on my elbows, gazing at the mouth of the passage. It was so; the Incas were not to be seen! Not one had issued from the passage.
It was incomprehensible to us then; later we understood. And we had not long to wait.
Harry and Desiree were bending over me, attempting to stop the flow of blood from a cut on my shoulder.
"We must have water," said Desiree. Harry straightened up to look about the cavern, which was so dark that we could barely see one another's faces but a few feet away.
Suddenly an exclamation of wonder came from his lips.
Desiree and I followed the direction of his gaze, and saw the huge, black, indistinct form of some animal suddenly detach itself from the wall of the cavern and move slowly toward us through the darkness.
