The Master labored doggedly to get his neutralizing apparatus
effectively operating once more; and besides this, he spent hours
locked in his cabin, working on other apparatus the nature of which
he communicated to no one. But the Legion knew that nothing could
save them from long-range naval guns, if that kind of attack should
develop. They needed no urging to put forth stern, unceasing energies.
Twice smoke on the horizon raised the alarm; but nothing came of it.

With great astuteness the Master had the wireless put in shape, at
once, and sent out three messages at random, on two successive days.
These messages stated that _Nissr_ had been sighted in flames and
falling, in North latitude 19 deg., 35'; longitude 28 deg., 16', or about two
hundred and fifty miles north-west of the Cape Verdes; that wreckage
from her had been observed somewhat south of that point; and that
bodies floating in vacuum-belts had been recovered by a Spanish
torpedo-boat.

No answer came in from any of these messages; but there was always
an excellent chance that such misinformation would drag a red herring
across the trail of pursuit.

Men never slaved as the Legionaries did, especially toward the end.
The last forty-eight hours, the Master instituted night work. The men
paused hardly long enough to eat or sleep, but snatched a bite when
they could, labored till they could do no more, and then dropped in
their places and were dragged out of the way so that others could
take hold. Some fell asleep with tools in hand, stricken down as if by
apoplexy.

The Master had wisely kept the pace moderate, at first, but had
speeded up toward the end. None grew more haggard, toil-worn, or
emaciated than he. With blistered hands, sweat-blinded eyes, parched
mouths and fevered souls these men fought against all the odds of
destiny. Half naked they strove, oppressed by heat, sun, flies,
thirst, exhaustion. Tobacco was their only stay and solace. The
Master, however, only chewed khat leaves; and as for "Captain Alden,"
she toiled with no stimulant.

It was 7:33, on the morning of the sixth day, that Frazier--now chief
engineer--came to the Master, as he was working over some complex bit
of mechanism in his cabin. Frazier saluted and made announcement:

"I think we can make a try for it now, sir." Frazier looked white and
wan, shaking, hollow-eyed, but a smile was on his lips. "Two engines
are intact. Two will run half-speed or a little better, and on
