“Oh! come over here, Dick!” he exclaimed, as though thrilled by a discovery he had made. “I’ve found something!”

When Dick bent over and took a look he laughed.

“Just what I was expecting we’d run across somewhere around,” he said. “The plain imprint of a bare foot! And no human being, wild man or not, ever made that mark, let me tell you, Leslie.”

“It does look somewhat queer I own up, Dick.”

“For a human being I should say it was impossible,” continued the other. “Notice its peculiar shape in the first place. And the foot is hardly longer than the toes. Yes, and they’ve got long nails on them in the bargain. There’s also a pad to the sole that no human ever has.”

Leslie’s eyes were staring. He turned them on his companion with an interrogation point in each orb. Somehow Dick was usually to be depended on to rise to an occasion like this, and find out the truth. His chums had long ago learned how absolutely they could depend on him when the necessity arose.

“What sort of animal, Dick, would have feet like those?” he asked, boldly.

“WHAT SORT OF ANIMAL WOULD HAVE FEET LIKE THOSE?” HE ASKED.

“Well, a gorilla might, for one,” Dick declared.
