“I hunted for the tracks after discovering the robbery,” replied the other, moodily. “After I had found them I trailed the three thieves half a mile out of camp. Then, anxious to take up the job in the right way, I came back to get some guns and men. That was when the mob met me, and chased me in here, where I had prepared for a long siege.”

“Then it’s your opinion, is it, that three strangers broke into the strong room, and rifled it; after which they hurried away?” asked Bob.

“That about covers the ground; and as they have had a big start I’m afraid its goin’ to be a hard job overhaulin’ ’em,” replied Mr. Riley.

“Perhaps it may,” said Frank, as he looked serious; “but two hundred pounds is some weight to carry any distance; and we have good horses, if they happen to take to the plain.”

Here was a new dilemma. He had expected that with the strike well settled, peace would descend on Cherry Blossom mine; and that presently he and Bob might gallop back home with cheering news.

But it would be another thing to find himself compelled to tell his father that some clever robbers had broken open the strong room, where the proceeds of the run at the stamp mills were kept behind lock and key, making a safe get-away.

“Bob, you hear what’s been going on; how are we going to stand for it?” Frank asked, turning to his chum.

“By doing our level best to get that treasure back!” was the prompt response.

“You hear, Mr. Riley,” continued Frank. “Suppose, then, you turn things over to the new superintendent right now, and come along with us.”

“I’m just wild to get started, Frank,” declared Mr. Riley. “Because, you see, I feel that I’m partly to blame for this loss. But, if it hadn’t been for the upset condition of things around that time, make up your mind it could never have happened. My attention was taken up by the actions of the men. Sometimes I find myself wondering whether it just happened that way; or if the strike wasn’t engineered to cover the crime of robbery.”
