"Not far from the surface now, that's certain," he thought, with considerable satisfaction. "And yet, hang me if I can see an opening of any sort yet."
On and on he went, until nearly a hundred feet more had been passed.
The cave had widened out, but now it narrowed once again to less than a dozen feet. The roof, too, sloped downward until it occasionally scraped the crown of his sombrero.
The light of the lantern began to splutter and flare up, showing that the oil in the cup was running low.
"If only the thing lasts until I find the door to this confounded prison," he thought.
Suddenly a peculiar hiss sounded out upon the darkness.
Pawnee Brown knew that hiss only too well, and leaping back he snatched a pistol from his belt.
The hiss was followed by a rattle, and now, flashing the light around, the scout saw upon a flat rock the curled-up form of a huge rattlesnake.
The eyes of the reptile shone like twin stars, and when Pawnee Brown discovered him he was getting ready to strike.
The rattler was less than six feet away, and the scout knew that he could cover that space with ease. Therefore, whatever was to be done must be done quickly.
