ith a
yellow funnel and two rakish-looking masts, with light spidery rigging.
Between her masts was suspended a parallel sort of "antennae," wires
betokening that she carried wireless. At her bow the foam creamed up as
she rushed through the water on her errand of mercy.

With what anxiety those on the _Good Hope_ watched her, may be imagined.
Their eyes fairly burned as they regarded the race of their rescuers
against the fire which raged below them. For the two holes cut by Rob
and Merritt, while they had had the good effect of attracting aid, had
also had a less gratifying result.

Through them the air had been transmitted to the flaming mass below, and
flames were now shooting up through them and enlarging the openings
every instant. The air grew so fearfully hot that all were compelled to
beat a retreat to the extreme stern of the _Good Hope_.

Little was said as the yacht rounded up as close to the burning ship as
she dared, and lowered a boat. By this time clouds of black smoke, shot
with livid flames, were shooting skyward above the doomed craft. It was
a fortunate thing for the castaways that no wind was stirring or this
story might have had a different termination.

The boat was manned by sailors in white duck clothes and was guided by a
lad wearing the Boy Scout uniform. As soon as they saw this the boys
gave the cry of the Eagle Patrol. As the long drawn "Kree-ee-ee!" died
out, the boy in the stern stood erect and gave the Scout salute. Then
followed a long-drawn, growling shout:

"How-oo-oo-oo!"

"That's the cry of one of the Wolf Patrols!" cried Merritt.

"Yes; and that boy is a Wolf," declared Rob.

"Well, at all events he comes in sheep's clothing," the ensign could not
resist saying.

The next instant the boat was under the stern and the rescued castaways
were sliding down a rope into it. Hardly a word was spoken while this
was going on; the work in hand was too important.

But hardly had they all found places before, in an earnest voice, the
ensign exclaimed:

"Pull for your lives, men; spare no time."

"Why, you are safe enough now," declared the Wolf Scout.

"Far from it," declared the young officer seriously, "the log book of
that craft spoke of dynamite on board. They used it to blast their way
out of the polar ice. I think----"

A terrific concussion that threw them all from their seats interrupted
him. Then came a blinding flash, and this in turn was followed by an
explosion tha
