CHAPTER XXIII.
It is not an uncommon occurrence for a rascal to overreach himself. It is the thing Arthur Hoyt did when he refrained from shooting Harry and resorted to the more cruel but longer device of starving him to death.
If he had gone away from the cave within ten minutes of reaching it, he would not have been seen by a lurking witness among the rocks.
This person had been hurrying along the trail, more than ten minutes behind Hoyt, and came upon him as he was toiling with the ponderous boulders.
At the instant of seeing him, the stranger darted behind a rock and watched him with a deep interest.
He kept himself hidden until Hoyt had gone, and then seemed for a moment undecided whether to follow him or to investigate the reason of the piling up of the stones in the cave.
"I can follow him after I've taken a look," he muttered.
With this determination he ran over to the cave and looked in and tried to make out the meaning of the heap of stones.
"Now, what in the world did he do that for?" he asked himself. "Well, whatever he did it, for, it'll be worth my while to learn it, for I know he'd never 'a taken all that trouble for nothing. He isn't the sort to work like that for fun."
So the newcomer went over to the pile and studied it; but making nothing of it, owing to the care with which Harry had been covered up, he doggedly set to work to remove and undo all that Hoyt had done.
