There was no need that Claus should tell Casper this, and for the next fifteen minutes Claus never said a word, but listened intently. He told about Julian's habit of going to the express office on the day that "old horse" was offered for sale, until finally he bought the secret of a gold-mine which was hidden away in a box that came near being sold for twenty-five cents. The box was addressed to S. W. Haberstro, and the boys had put four advertisements in the papers asking that man to show himself; and, if he did not show up in reasonable time, the money was to be theirs.

"Here is a copy of the Democrat, with a copy of the advertisement in it," said Casper. "I knew you would want to know everything, and so I brought it along. A hundred thousand dollars! Now, why couldn't I have bid on that box? That little snipe does not get any more money than I do, and yet he had to go and buy himself rich."

"Then it seems that you are not a broker's clerk after all," said Claus. "I don't know as I blame you."

"You see I would get discharged if any of the company officers should find me dressed up in citizen's rig," said Casper. "I can go among the boys, now, and have a good time."

"I don't know that I blame you," repeated Claus. "I will keep your secret. Well, go on. I begin to understand the matter now."

"I tell you I was mad when I found out that they were going to advertise for old man Haberstro," said Casper. "I called them everything but decent boys, and went to work to conjure up some plan for getting the box for my own. I got it, too——"

"You did? Then you are all right."

"Not so near right as you think I am. Julian got some keys that would fit my door, and went in and stole it."

"Whew! They are a desperate lot; ain't they?"

"That is just what they did; and, furthermore, Julian gave the box into the hands of Mr. Wiggins, our chief telegraph operator. Now, I want you to come down there, pass yourself off for Haberstro, and claim that box. Can you do it?"
