e called to the
crew.

Tom crawled back to the main cabin and told Mr. Damon and the others
what was to be attempted.

"Koku, you come and help move things," requested Tom.

"Me move anything!" boasted the giant, who, because of his great
strength and reserve power did not seem as greatly affected as were the
others.

Going back to the engine room with Koku, Tom assisted, as well as he
could, in the shifting of pieces of apparatus, stores and other things
that were movable. They all worked at a great disadvantage except Koku,
and he did not seem to feel the lack of vitalizing air.

One thing after another was shifted, and still the M. N. 1 maintained
the dangerous angle.

"It isn't going to work!" gasped Tom, as he noticed the indicator which
told to what angle the craft was still off an even keel. "We'll have to
try something else."

"Is there anything to try?" asked Earle, in a faint voice. He was on
the point of fainting for lack of air.

Tom looked desperately around. There was one piece of heavy machinery
that might be moved to the other side of the engine room. It was bolted
to the floor, but its added weight, with that of the crew and
passengers, together with what had already been shifted, might turn the
trick.

"Let's try to move that!" said Tom faintly, pointing to it.

"It will take an hour to unbolt it," said one of the men.

"Koku!" gasped Tom, pointing to the heavy apparatus. "See if--see if
you--"

Tom's breath failed him, and he sank down in a heap. But he had managed
to make the giant understand what was wanted.

"Koku do!" murmured the big man. Striding to the piece of machinery,
the legs of which were bolted to the floor, Koku got his arms under it.
Bending over, and arching his back, so as to take full advantage of his
enormous muscles, the giant strained upward.

There was a cracking of bone and sinew, a rasping sound, but the
machinery did not leave the floor.

"Him must come!" gasped the giant. "One more go!"

He took a hold lower down. Tom's eyes were dim now, and he could not
see well. Some of the men were unconscious.

Then, suddenly, there was a loud, breaking sound, and something tinkled
on the steel floor of the submarine engine room. It was the heads of
the bolts which Koku had torn loose. Like hail they fell about the
giant, and in another instant the big man had pulled loose the machine,
weighing several hundreds of pounds. In another moment he shoved it
across the
