an in the cave! If there's one,
there may be more. I guess we'd better look to our guns. They may
attack us!" and he hurried back into the airship, followed by Ned
and the others.

CHAPTER XIV

THE RIVAL AIRSHIP

Well armed, the adventurers again ventured out into the cave. But
they need not have been alarmed so soon, for there were no signs of
any more Indians.

"I guess that one was a stray Eskimo who took shelter in here from
the storm," said Abe Abercrombie.

"Are we in the neighborhood of the Alaskan Indians and Eskimos?"
inquired Ned.

"Yes, there are lots of Indians in this region," answered the old
miner, "but not so many Eskimos. A few come down from th' north, but
we'll see more of them, an' fewer of th' pure-blooded Indians as we
get nearer th' valley of gold. Though t' my mind th' Indians an'
Eskimos are pretty much alike."

"Well, if we don't have to defend ourselves from an attack of
Indians, suppose we look over the airship," proposed Tom.

"It's too dark to see very much," objected Ned. But this was
overcome when Tom started up a dynamo, and brought out a portable
search-light which was played upon the superstructure of the RED
CLOUD. The gas-bag was the only part of the craft they feared for,
as the hailstones could not damage the iron or wooden structure and
the planes were made in sections, and in such a manner that rents in
them could easily be repaired. So, in fact, could the gas-bag be
mended, but it was harder work.

"Well, she's got some bad tears in her," announced Tom as the light
flashed over the big bag. "Luckily I have plenty of the material,
and some cement, so I think we can mend the rents, though it will
take some days. Nothing could have been better for us than this
cave. We'll stay here until we're ready to go on."

"Unless the Indians drive us out," said Abe, in a low tone.

"Why, do you think there is any danger of that?" inquired Tom.

"Well, th' brown-skinned beggars aren't any too friendly," responded
the old miner. "Th' one that was in here will be sure to tell th'
others of some big spirit that flew into th' cave, an' they'll be
crowdin' around here when th' storm's over. It may be we can fight
'em off, though."

"Maybe they won't attack us," suggested Ned, hopefully. "Perhaps we
can make them believe we are spirits, and that it will be unlucky to
interfere with us."

"Perhaps," admitted Abe, "though my experience has been that these
Indians are a bad
