“Sure thing,” replied the other, as he stepped to one side; “here it is, sticking out from behind this crooked aspen, just as he flung it. Everything’s all right, Bob, old fellow.”

CHAPTER XX
AN ASTONISHING DISCOVERY

“Hurrah!”

Bob could not keep from giving voice to his delight in this way. He saw Frank tugging at some object, and then throw it on his shoulder.

“Keep right along up, Bob; and don’t let him pull the wool over your eyes. We may want to take him to Phoenix yet, and hand him over to the marshal,” was what Frank was saying.

Bob could hear the man give a dismal grunt. He had not suspected the presence of others when he started to work this trick on his former comrades, with the idea of making off with the gold they had secured.

In this way, then, they retraced their way upward. Bob would never have dreamed that they had covered such a distance in the short space of time they had been pursuing the escaping thief. But then, it had been all down-hill, and the desire to get away had caused the man to cover ground at a lively rate.

Frank had found the little stream again. He was making use of it to keep in a direct line for the lone shack, located somewhere beyond.

Once the man made an effort to break away, as though his fears overcame his discretion. But Bob was “on the job,” as he said himself. He did not lose his grip of the fellow, despite the abruptness of the wrench. And, remembering his instructions from Frank, he threw out his foot, and tripped the man, who fell heavily.

Frank came springing back in an instant.
