Jack estimated the height of the falls as being fully sixty feet. The boiling pool appeared to be about an acre or so in extent, and was furiously agitated by the constant pouring of the mighty falls. And now Jack became aware of a curious thing.
All about the edges of the pool, where the circular motion of the water had evidently cast them up, were myriads of bones. They appeared to be the remains of cattle and various kinds of game; but some of them caused Jack to shudder as he had a distinct notion that they were of human origin.
All at once, while he was still exploring the strange place into which he had fallen, he came across a bleached skull lying amid a pile of bones and débris. The ghastly relic gave him a rude shock as he gazed at it.
“Gracious!” the boy exclaimed, with a shudder, “this place might well be called a Pool of Death. How fortunate I am to be alive; although how I am going to get out of this scrape I don’t know. One thing is certain, I cannot remount by the falls. I must see what lies in the other direction.”
Up to that moment, so agitated had the castaway boy been that he had almost entirely forgotten the Mexican with whom he had had the battle on the raft. The thought of the man now suddenly recurred to him. Jack sighed as he realized that the Mexican could hardly have been so fortunate as he had been. In all probability he had forfeited his life to the Pool of Death.
With such melancholy thoughts in his mind Jack set about exploring the rocky basin for some means of exit. Although he was determined not to give way to despair, the boy could not but own that his situation was well–nigh desperate. He was many miles from his friends, and probably in an uninhabited part of the country. He had no food; nor even if there had been any game had he the means of shooting it.
His hunger was now beginning to make itself painfully manifest. On some bushes that clung to the walls of the Pool of Death were some bright–colored berries, but Jack dreaded to try them. For all he knew they might be deadly poison.
Searching for an exit, Jack was not long in finding one. The pool was drained by a narrow crevice in the rocky walls, forming a passage. On the brink of the water was a strip of beach, not much wider than a man’s hand. Beside this pathway the water roared and screamed in its narrow bounds, but Jack knew that if he was to get out of this place at all he must dare the rocky passage.
Stifling his fears as well as he could, the famished, bedraggled lad struck pluckily out. Sometimes the passage grew so narrow that he could have bestridden the stream. At other points it widened out and, looking up, Jack could see the blue sky far overhead. In reality the passage was not more than half a mile in length but, so carefully did Jack have to proceed, it appeared to be four times that length at least.
