. From his father and
mother Roger got some more details concerning the missing property. A
map was produced, and also some papers, and the son was advised to hunt
up an old miner and prospector named Abe Blower.

"Abe Blower knew your Uncle Maurice well," said Mrs. Morr, to her son.
"They were friends for years. I am sure if you can find Mr. Blower he
will do all he can for you, and for me, too."

"Then I'll do what I can to find him, first of all," answered Roger.

At last came the time when Dave must leave the Morr home and return to
Crumville. He was going alone, but he promised to keep in constant
communication with the others.

"I wish I was going on that western trip," said Shadow, wistfully.
"You'll have barrels of fun, and if you do locate that Landslide
Mine--well, it will be a big feather in your cap."

"I'd like to go, too," said Buster.

"I reckon we'd all like to go," cried the others, in concert.

"Well, there is just this much about it," returned Dave. "Anybody who
has the price can go on that personally-conducted tour to Yellowstone
Park, and, so far as I am concerned, you can go from there into the
mountains and look for the mine."

"Why, of course!" burst out Roger. "If any of you want to go, just say

This brought on a discussion lasting nearly an hour. In the end several
of the lads said they would see what they could do, and would write
about it later, or telegraph.

"Say, but wouldn't it be grand if we could locate that lost mine!" cried
Phil, enthusiastically.

"Well, we'll have a try at it," returned Dave.

At last came the time for Dave to leave. Some of the others had already
gone. Roger drove his chum down to the railroad station in the runabout.
The two were alone. Dave noticed that the senator's son seemed unusually
thoughtful.

"What's up, Roger?" he asked, at last. "You don't seem quite like
yourself."

"Oh, I don't know that I ought to say anything, Dave," was the
hesitating answer.

"If there is anything I can do----"

"No, it isn't that." Roger gave a deep sigh. "I wish we could locate
that mine!" he murmured.

"So you were thinking about that? Well, we may have luck. Let us hope
so," and Dave smiled.

"I might as well tell you how it is," continued Roger, as he drove up to
the little railroad station. He looked around, to make sure that no
outsiders were listening. "You know father comes up for re-election this
fall."

"Oh, does his term as senato
