miliar with the construction of the propellers, housings, and the
auxiliary gearing required.

It was estimated that it would require six months to complete our
preparations in view of the fact that the utmost secrecy must be
maintained to keep the project from the ears of Zat Arras. Kantos Kan
was confident now that the man's ambitions were fully aroused and that
nothing short of the title of Jeddak of Helium would satisfy him.

"I doubt," he said, "if he would even welcome Dejah Thoris' return, for
it would mean another nearer the throne than he. With you and
Carthoris out of the way there would be little to prevent him from
assuming the title of Jeddak, and you may rest assured that so long as
he is supreme here there is no safety for either of you."

"There is a way," cried Hor Vastus, "to thwart him effectually and for
ever."

"What?" I asked.

He smiled.

"I shall whisper it here, but some day I shall stand upon the dome of
the Temple of Reward and shout it to cheering multitudes below."

"What do you mean?" asked Kantos Kan.

"John Carter, Jeddak of Helium," said Hor Vastus in a low voice.

The eyes of my companions lighted, and grim smiles of pleasure and

Whom they choose may count upon the loyalty of my sword, nor shall I

Helium, and Zat Arras is his representative."

"As you will, John Carter," said Hor Vastus, "but--What was that?" he
whispered, pointing toward the window overlooking the gardens.

The words were scarce out of his mouth ere he had sprung to the balcony
without.

"There he goes!" he cried excitedly. "The guards! Below there! The
guards!"

We were close behind him, and all saw the figure of a man run quickly
across a little piece of sward and disappear in the shrubbery beyond.

"He was on the balcony when I first saw him," cried Hor Vastus.
"Quick! Let us follow him!"

Together we ran to the gardens, but even though we scoured the grounds
with the entire guard for hours, no trace could we find of the night
marauder.
