The train pulled into Green River at eight o'clock that night, and they all went to the leading hotel, and Ted registered them as coming from the ranch.

During the evening the boys mingled with the crowd in the hotel lobby, talking cattle, and met many of the representative women of the section.

They were out after a bunch of stockers, and promised to be in the neighborhood for several days and to visit the ranches and look over the stock.

One of the men whom they met was introduced to them as Colonel Billings, ranch owner and speculator in cattle.

He was a middle-aged man of most pleasant features--benign, good-natured, and yet shrewd. He dressed well for a cowman, and from his pink, bald crown and gray chin whiskers down to his neat shoes, he looked the part of the prosperous business man.

"I have a lot of stock such as I think you boys need out at my ranch,"

he said to Ted, when he learned that they wanted to buy. "I'd like to have you bring your party out to the place and stay several days as my guests. You would then have plenty of time to look the stock over, and if you like them I'm sure we can strike a bargain."

Ted thanked him and promised to go out to look at the stock, but as for the invitation for the whole party to stop at the ranch, he would have to consult the wishes of the party. He rather liked the colonel, who was, apparently, bluff and sincere.

As Ted was on his way to the bank which had issued the bill which he had found in the haunted house, he stopped suddenly. He had just seen a young woman enter a store hurriedly, and look at him over her shoulder as she did so. She it was who had slipped the note of warning into his pocket in the Union Station, in St. Louis.

Evidently she was trying to avoid him. But why? He wanted to thank her for that kindly service, and, quite naturally, he had some curiosity to know who she was.

Without apparently hurrying he followed her into the store, and looked around for her. She was not in sight, and he walked up and down the aisles between the counters, but could not find her.

Then he observed that there was a back door to the store, which opened onto an arcade. She had escaped him through that, and Ted looked up and down the arcade. At the far end, where it opened out into the public square, a carriage stood, and a young lady was getting into it.

It was the young lady of the subtle perfume and the note.

In a moment she was gone.

He was not far from the bank, and giving the young woman no more thought, for he was sure he would see her again, for she seemed to be mixed up in his fortunes in some manner, he made his way to the financial inst.i.tution and asked for the president.

"You will find Mr. Norcross in his private office at the end of the corridor," said the clerk.

At the door of the office Ted found a colored messenger, who stopped him and asked his business.

"Is Mr. Norcross in his office?" asked Ted.

"Yes, sah, but he is busy," answered the messenger.

"Well, take my card in to him, and tell him I would like to see him when he is at leisure."

The negro went away, and in a few moments returned to say that Mr.

Norcross would be glad to see Mr. Strong presently.

While Ted waited he stood looking out of the window into the street. The door behind him opened, and he turned.

Walking rapidly down the corridor was the man with the pointed beard, whom he had seen in the Union Station in St. Louis give the signal to the girl who had slipped the note into his pocket.

Ted stared after him. The mystery of the note was getting thicker. But he would try to think it out later.

He found Mr. Norcross an elderly, but active man.

"What can I do for you, Mr. Strong," said the banker, referring to Ted's card.

"I come to you for information concerning a recent robbery and the murder of an express messenger in an express car in St. Louis," said Ted.

"In what capacity do you come?"

"As an officer of the government."

"Oh, ah, rather young for such work, aren't you?"

"Pardon, but that has nothing at all to do with it. I am a deputy United States marshal, and have received instructions to examine into certain matters regarding the recent robberies from express trains in this part of the country."

"I suppose you have your credentials as an officer."

"I think I can convince those who have the right to know that I am what I profess to be."

"Very well. I meant no offense, but there have been so many violent things done out here, that naturally a banker desires to at least know something of his callers. What can I do for you?"

"Did your bank make a shipment of currency to the East, last week?"

"Yes, sir, that is a well-known fact."

"What was the amount?"

"Forty thousand dollars. It was to meet some paper which was due in St.

Louis."

"And it was stolen from the express car?"

"Yes. The express company has reimbursed us for it."

"What sort of currency was it?"

"Mostly of our own issue."

"Do you recognize this bill?"

Ted took from his pocket the counterfeit bill of the bank, and handed it to the president, who looked at it a moment and handed it back.

"Yes, that is one of the bills. The money sent was all in that series of numbers."

Ted picked the bill up, and put it in his pocket.

"Here, you mustn't take that," said the president. "That is the property of the bank. Give it to me. The express company will need it for evidence."

"Then I will keep it. It will be safer with me."

A suspicion had entered Ted's mind, which was strengthened by the conduct of the president, who was white-faced and trembling.

"From your examination of the bill, you are positive that it was one of those shipped to St. Louis?"
