Alvarez, who doubtless saw that his best course was to tell the truth, launched into a fairly accurate account of the adventures on the raft, and the thrilling descent into the Pool of Death. Ralph Stetson shuddered as he listened. Walt looked almost incredulous. It seemed hard to believe that any human being could have “shot” that awful cataract and lived.
By this time it was dark, and, as it would have been too dangerous to attempt using the improvised rope ladder at night, Captain Atkinson decided to camp where they were. Alvarez was not bound, as his captors deemed it impossible for him to escape. Instead, he sat around the fire with them, and to anyone not knowing the circumstances he appeared more like a friend or a member of the party than an alien prisoner.
But they had not counted on the wily ways of the ex–cattle rustler. Even Captain Atkinson, old plainsman as he was, was completely taken in by the seeming resignation of Alvarez to his fate. For this reason no guard was placed on the man that night. This Captain Atkinson was to regret bitterly some hours later, for, when day dawned, there was no sign of Alvarez.
The Ranger guessed the truth at once. Alvarez had overheard their talk about the rope ladder and the ponies which had been left tethered in the grass at the falls. There was not the slightest doubt that he had made use of the ladder in the night, and helped himself to one of the ponies. If he had not taken all three they would be lucky, thought the captain.
The boys were anxious to set off in pursuit of the escaped prisoner at once, but Captain Atkinson made them prepare and eat a scanty breakfast first.
“Alvarez must be miles away by this time,” he said, “that is, provided he made the climb in safety.”
After breakfast no time was lost in striking out for the falls. The ladder was just as they had left it, except that one of the cross sticks had snapped, showing that someone must have climbed it in the darkness and missed his footing.
“We are at least fortunate that he left the ladder,” said Captain Atkinson. “I had a half–formed fear that he would have destroyed it.”
“Surely he would not have done such a dastardly thing as that!” exclaimed Walt.
