t a
fellow has to sign," observed Sam. "If he had done that, it would be
easy to find him."

"That's true."

The train they were on was an express, making but few stops and would
reach St. Paul late in the evening. It was only about three-quarters
filled, so the Rovers had had no difficulty in getting a section of a
sleeper. Whether they would go further than St. Paul was, however, as
yet a problem.

"Next stop Milwaukee!" was the cry, and soon the train rolled into that
city. Anxiously the two brothers looked out and saw one of the
trainmen take several telegrams from a man on the platform. After the
train had started again the trainman came through the train.

"Telegrams for Miss Baker, Mr. Josephs and Mr. Rover!" he called out.

"Here you are!" cried Sam, eagerly. "Rover." And the telegram was
passed over. Hastily the envelope was torn open and the contents
scanned. The boys looked at each other blankly. The telegram read as

"No young man answering to name Tom Rover on this train. Will watch
passengers closely as instructed.

"FOLSOM, _Conductor_."

"What do you make of this, Dick. Maybe Tom didn't use that ticket
after he bought it," gasped Sam.

"But that ticket seller saw him rush for the gate. He must have gone
on the train, Sam. He probably didn't answer to his name because if he
is out of his mind he has forgotten what his real name is. And so long
as he keeps quiet the trainmen won't suspect anything wrong with him."

"Perhaps we'll get another telegram at St. Paul."

"I hope so."

On and on rolled the train through the afternoon, coming presently to
the shore of the upper Mississippi, with its wide stretches of
marshland and its dead trees. It was not an inviting scene, and the
two Rovers were glad enough, when the time came, to turn from it and go
to the diner for dinner.

There was to be a stop of ten minutes at St. Paul and in that time the
boys must make up their minds whether they were going to continue on
that train or not. If they laid over, several more hours of precious
time would be lost.

It was well towards midnight when the train reached St. Paul and a
number of sleepy passengers got off and others got on. Dick and Sam
waited impatiently for a messenger to appear. The telegram was there,
sure enough, and this time it carried more interesting information.

"Queer-acting young man found, but says his name is Paul Haverlock.
