He knew every inch of the trail. Near the spot where he was, was a hole in the side of the hill where some badly directed man had once started to dig a gold mine. He had not gone far before he discovered that iron pyrites was the only "gold" in that locality. The hole was never filled up, and was now almost hidden from sight by a heavy growth of underbrush.

He stooped down and felt with his hands. A thrill ran through him.

"The mail pouches!" he exclaimed in a hoarse whisper. "The mail pouches the robbers took from me! They hid them here, and I've found them! What luck!"
