e their heads, Tom and the
others were no less surprised, though, of course, their fear was not
exactly the same as that of the Alaskan natives.

"Do you really think that is Andy Foger?" asked Ned, as they watched
the progress of the triplane.

"I'm almost sure of it," replied Tom. "That craft is built exactly
as his was, but I never expected him to have such good luck sailing
it."

"It isn't going very fast," objected Ned.

"No, but it can navigate pretty well, and that's something. He must
have hustled to get it together and reach this point with it."

"Yes, but he didn't have to travel as far as we did," went on Ned.
"He put his ship together at Sitka, and we came from Seattle."

"Bless my memoranda book!" exclaimed Mr. Damon. "The Fogers here!
What's to be done about it?"

"Nothing, I guess," answered Tom. "I'd just as soon they wouldn't
see us. I don't believe they will. Get back into the cave. We must
use strategy now to get ahead of them. There will be a race to the
valley of gold."

"Well, he served us one good turn, anyhow, though he didn't mean
to," put in Abe Abercrombie.

"How?" asked Mr. Parker, who was still examining his gun, as though
trying to understand it.

"He scared away them pesky natives," went on the miner. "Otherwise
we might have had a fight, an' while I reckon we could have beat
'em, it's best not to fight if you kin git out of it."

The gold-seekers had withdrawn inside the mouth of the cave, where
they could watch the progress of the rival airship without being
seen. The Indians had disappeared beyond a snow-covered hill.

The airship of Andy Foger, for such it subsequently proved to be,
floated slowly onward. Its progress was not marked with the speed of
Tom's craft, though whether or not the occupants of the ANTHONY (as
Andy had vain-gloriously named his craft after himself) were
speeding up their motor, was a matter of conjecture.

The adventurers held a short consultation, while standing at the
mouth of the cave watching the progress of the ANTHONY. It rose in
the air, and circled about.

"He certainly IS trying to pick us up," declared Ned.

"Well, we'll start out after him to-morrow," decided Tom. "I think
all the patches will hold then."

They resumed work on the RED CLOUD, and that night Tom announced
that they would start in the morning. Meanwhile Andy's craft had
disappeared from sight. There was no further evidence of the
Indians.

"I don't reckon they'll
