what had happened at Senator Morr's home, and about the lost mine.
"It certainly sounds like a romance!" declared Dave's father, referring to the lost mine.
"But I have heard of such things before," answered his brother. "I know of several valuable mines in South America that were lost through earthquakes. Landslides have not only buried mines, they have buried cities as well."
"Oh, Dave, supposing you went to look for that mine and there was another landslide!" gasped Jessie, and turned pale.
"That's a risk we'd have to run," was his answer. "But I'd be very careful as to where I went, Jessie."
"I don't know about this," put in Mr. David Porter, with a grave shake of his head. "Better take the trip through Yellowstone Park, Dave, and let the Landslide Mine slide," and he smiled, faintly.
"Oh, I promised Roger that I'd go with him,—and Phil is going, too!" pleaded Dave. "We'll be very careful."
"I might go with you myself, only I think I ought to stay with the party to go through the Park," said Dunston Porter.
"Yes, we want you with us!" cried Laura.
"I don't like this at all!" pouted Jessie, and looked somewhat reproachfully at Dave.
