"And I'll help all I can, and I know my uncle will, too," said Nat, with ready sympathy.

The boys had arranged themselves comfortably in the train, which, by this time, had speeded several miles from Denton. The car was not well filled as it was early and no large cities had been reached. As station after station was passed, however, passengers began to take the seats until the cars were comfortably filled.

The boys had taken passage in a through sleeper to Chicago, and got their meals in the dining car ahead. They had supper in Scranton, where the train waited about half an hour to connect with another. As the boys came back to their seats in the sleeper, which had not yet been made up, they saw several new passengers.

One was a tall, rather rough looking man, who seemed to have suddenly acquired wealth. His clothes were good but did not fit him well, and he seemed ill at ease in them. There was a big diamond in his shirt front, and he had a heavy gold chain across his vest.

"Guess I'm entitled to the best that's goin'," he said in a loud tone as he sat in one seat and put his big feet up in the one opposite. "I've paid for this whole section an' I'm going to use it. I ain't worked hard all my life for nothing. Just sold my share in a coal mine," he said to the boys, whose seats were near his. "Now I'm going to enjoy myself. Going to the 'Windy City'! that's what I am. Got friends in Chicago that'll be glad to see me an' my pile," and he pulled out a big role of bills. "My name's Josh Post, an I'm set in my ways," he added.

The boys did not make any answer, but, at the sound of the big man's voice a passenger in the seat ahead of him turned and looked to see who was speaking. As he did so the former mine owner happened to be displaying his money, and the eyes of the other passenger gleamed in a dangerous sort of way.

As he turned around to get a glimpse of the miner, Jack got a look at the face of the passenger who had shown such curiosity. The boy started. "Where have I seen him before?" he thought to himself. "I can't seem to place him." Then he leaned over and whispered to Nat. "Make an excuse to go to the end of the car, and on your way back take a look at the man in the first seat."

"All right," said Nat, who did not ask the reason. A little later he sauntered to the water cooler. He could hardly repress a start as he passed the man Jack had mentioned.

"Know him?" asked Jack, when his chum had regained his seat.

"Sure, in spite of his disguise, his new way of wearing his hair, and the fact that he has shaved off his moustache."
