Part 22 (1/2)

”'People couldn't possibly live in hydrogen instead of oxygen',” Arcot quoted, grinning. ”That's what they told me when I made my little announcement at the meeting on the Black Star situation. The only trouble was--they did. That suggestion of yours meets the same fate, Morey!”

”All right, you win,” agreed Morey. ”Now let's see if we can find the other nations on this world more friendly.”

Arcot looked at the sun. ”We're now well north of the equator. We'll go up where the air is thin, put on some speed, and go into the south temperate zone. We'll see if we can't find some people there who are more peaceably inclined.”

Arcot cut off the invisibility tubes. Instantly, all the enemy s.h.i.+ps in the neighborhood turned and darted toward them at top speed. But the s.h.i.+ning _Ancient Mariner_ darted into the deep blue vault of the sky, and a moment later was lost to their view.

”They had a lot of courage,” said Arcot, looking down at the city as it sank out of sight. ”It doesn't take one-quarter as much courage to fight a known enemy, no matter how deadly, as it does to fight an unknown enemy force--something that can tear down mountains and throw their forts into the air like toys.”

”Oh, they had courage, all right,” Morey conceded, ”but I wish they hadn't been quite so anxious to display it!”

They were high above the ground now, accelerating with a force of one gravity. Arcot cut the acceleration down until there was just enough to overcome the air resistance, which, at the height they were flying, was very low. The sky was black above them, and the stars were showing around the blazing sun. They were unfamiliar stars in unfamiliar constellations--the stars of another universe.

In a very short time, the s.h.i.+p was dropping rapidly downward again, the horizontal power off. The air resistance slowed them rapidly. They drifted high over the south temperate zone. Below them stretched the seemingly endless expanse of a great blue-green ocean.

”They don't lack for water, do they?” Wade commented.

”We could pretty well figure on large oceans,” Arcot said. ”The land is green, and there are plenty of clouds.”

Far ahead, a low ma.s.s of solid land appeared above the blue of the horizon. It soon became obvious that it was not a continent they were approaching, but a large island, stretching hundreds of miles north and south.

Arcot dropped the s.h.i.+p lower; the mountainous terrain had become so broken that it would be impossible to detect a city from thirty miles up.

The green defiles of the great mountains not only provided good camouflage, but kept any great number of s.h.i.+ps from attacking the sides, where the ray stations were. The cities were certainly located with an eye for war! Arcot wondered what sort of conflict had lasted so long that cities were designed for perpetual war. Had they never had peace?

”Look!” Fuller called. ”There's another city!” Below them, situated in a little natural bowl in the mountains, was another of the cone cities.

Wade and Fuller manned the ray projectors again; Arcot dropped the s.h.i.+p toward the city, one hand on the _reverse_ switch in case the inhabitants tried to use the magnetic beam again.

At last, they had come quite low. There were no s.h.i.+ps in the air, and no people in sight.

Suddenly, the outside microphone picked up a low, humming sound. A long, cigar-shaped object was heading toward the s.h.i.+p at high speed. It had been painted a dark, mottled green, and was nearly invisible against background of foliage beneath the s.h.i.+p.

”Wade! Catch that on the ray!” Arcot commanded sharply, moving the s.h.i.+p to one side at the same time. Instantly, the guided missile turned and kept coming toward them.

Wade triggered the molecular beam, and the missile was suddenly das.h.i.+ng toward the ground with terrific speed. There was a terrific flash of flame and a shock wave of concussion. A great hole gaped in the ground.

”They sure know their chemistry,” remarked Wade, looking down at the great hole the explosion had torn in the ground. ”That wasn't atomic, but on the other hand, it wasn't dynamite or TNT, either! I'd like to know what they use!”

”Personally,” said Arcot angrily, ”I think that was more or less a gentle hint to move on!” He didn't like the way they were being received; he had wanted to meet these people. Of course, the other planet might be inhabited, but if it wasn't--

”I wonder--” said Morey thoughtfully. ”Arcot, those people were obviously warned against our attack--probably by that other city. Now, we've come nearly halfway around this world; certainly we couldn't have gone much farther away and still be on the planet. And we find this city in league with the other! Since this league goes halfway around the world, and they expected us to do the same, isn't it fair to a.s.sume, just on the basis of geographical location, that all this world is in one league?”

”Hmmm--an interplanetary war,” mused Arcot. ”That would certainly prove that one of the other planets is inhabited. The question is--which one?”

”The most probable one is the next inner planet, Aphrodite,” replied Morey.

Arcot fired the s.h.i.+p into the sky. ”If your conclusions are correct--and I think they are--I see no reason to stay on this planet.

Let's go see if their neighbors are less aggressive!”
