ell acquainted with him."

"Why, yes, I remember him. He and I used to talk about what Larry and
I did at Putnam Hall. But is he in Seattle now, and have you his
address?"

"I think I have his address. Wait, I'll look," end Sam pulled a little
notebook out of his pocket. "He asked me to write to him some time,
but I never did more than mail him a postal. Yes, here is the address."

"Do you think he would help us, if he was home?"

"Sure I do. He got acquainted with Tom, and he knew what chums Tom and
Larry were at the Hall."

"Then we might telegraph him. It won't do any harm anyway."

A rather long telegram was prepared and sent from the next station at
which the train stopped. There the youths hoped for another message
from Folsom the conductor, but none came.

Slowly the hours dragged by, the express thundering along in the
meanwhile on its journey westward. They stopped at Livingston, and
there many passengers got off, bound for a trip through that great
natural wonderland, Yellowstone Park. At Helena they heard from Folsom
again. This time the message was one full of mystery.

"Cannot find Paul Haverlock anywhere. So far as known, he did not
leave train at any station. We are very much crowded, account special
excursion, and break down of Number 126. Attached two extra cars. He
may be hiding among new passengers. I can do no more."

"I think I can explain this," said the conductor of the train, when
Dick showed him the telegram. "Number 126, the train just ahead of
Number 182, the one your brother is on, broke down. Now, the second
train is carrying two cars of the other train, and most likely all of
the other train's passengers. So Folsom is having his hands full with
his extra duties. In the meantime your brother has disappeared,
probably in the crowd of extra passengers."

"If he didn't jump off the train," sighed Sam.

"Would he do that?" asked the railroad man,

"I don't know. A fellow who is out of his mind is liable to do
anything."

"That is true."

The train was now in the midst of the Rocky Mountains, but the Rovers
had no heart to look at the scenery.

"Oh, if only we get some sort of encouraging word at Spokane!" sighed
Sam.

"We ought to hear from Jim Hendricks," answered Dick. "That is, if he
is home and got our message." They knew that the Hendricks family were
rich and that Jim had a great deal of time to himself.

At Spokane they left the train, for
