CHAPTER II

_The Pipe-like Men_

Brand began to slacken speed on the morning of the thirteenth day
(morning, of course, being a technical term: there are no horizons in
space for the sun to rise over). Jupiter was still an immense distance
off; but it took a great while to slow the momentum of the space ship,
which, in the frictionless emptiness of space, had been traveling
faster and faster for nearly three hundred hours.

Behind them was the distant ball of sun, so far off that it looked no
larger than a red-hot penny. Before them was the gigantic disk of
Jupiter, given a white tinge by the perpetual fog blankets, its
outlines softened by its thick layer of atmosphere and cloud banks.
Two of its nine satellites were in sight at the moment, with a third
edging over the western rim.

"Makes you think you're drunk and seeing triple, doesn't it?"
commented Dex, who was staring out the thick glass panel beside Brand.
"Nine moons! Almost enough for one planet!"

Brand nodded abstractly, and concentrated on the control board.
Rapidly the ship rocketed down toward the surface. The disk became a
whirling, gigantic plate; and then an endless plain, with cloud
formations beginning to take on definite outline.

"About to enter Jupiter's atmosphere." Brand spoke into the radio
transmitter. Over the invisible thread of radio connection between the
space ship and Earth, four hundred million miles behind, flashed the
message.

"All right. For God's sake, be careful," came the answer, minutes
later. "Say something at least every half hour, to let us know
communication is unbroken. We will sound at ten second intervals."

The sounding began: _peep_, a shrill little piping noise like the
fiddle of a cricket. Ten seconds later it came again: _peep_.
Thereafter, intermittently, it keened through the control room--a
homely, comforting sound to let them know that there was a distant
thread between them and Earth.

Lower the shell rocketed. The endless plain slowly ceased its rushing
underneath them as they entered the planet's atmosphere and began to
be pulled around with it in its revolution. Far to the west a faint
red glow illumined the sky.

The two men looked at each other, grimly, soberly.

"We're here," said Dex, flexing the muscles of his powerful arms.

"We are," said Brand, patting the gun in his holster.

The rapid dusk of the giant planet
