else, goes sour. But I want to have the emergency overload where I can decide whether or not an emergency overload is to be accepted. I'd feel a sight more than silly if that overload relay popped while I was a couple thousand feet up.

"Trouble with all this new stuff of ours is that we simply haven't had time to find out all the 'I never thought of that' things that can go wrong. If the grid resistor on that oscillator went out, for instance, what would it do?"

Arcot cocked an eye at the power pack, visualizing the circuits. "Full blast, straight up, and no control. But modern printed resistors don't fail."

"That's what it says in all the books." Wade nodded wisely. "And you should see the stock of replacement units every electronics shop stocks for purposes of replacing infallible units, too. You've got a point, my friend."

"I can see four ways we can change these things to fail-safe operation, if we add Morey's emergency cut-off switch. If it did go on-full then, you could use intermittent operation and get down," Arcot acknowledged.

"Anybody know what silly fail-unsafe tricks we overlooked in the Ancient Mariner?" Fuller asked.

"That," said Wade with a grimace, "is a silly question. The 'I didn't think of that' type of failure occurs because I didn't think of that, and the reason I didn't think of it is because it never occurred to me. If we'd been able to think of 'em, we would have. We'll probably get stuck with a few more yet, before we get back. But at least we can clean up a few bugs in these things now."

"Forget it for now, Wade, and get that chow on," suggested Fuller. He was lying on his back, clad only in a pair of short trunks, completely relaxed and enjoying life. "We can do that when it's dark here."

"Fuller has the right idea," said Morey, looking at Fuller with a judicious eye. "I think I'll follow his example."

"Which makes three in favor and one on the way," said Arcot, as he came out of the ship and sank down on the soft sand of the beach.

They lay around for a while after lunch, and then decided to swim in the cool waters of the lake. One of them was to stand guard while the others went in swimming. Standing guard consisted of lying on his back on the soft sand, and staring up at the delightful contrast of lush green foliage and deep blue sky.

It was several hours before they gathered up their things and returned to the ship. They felt more rested than they had before their exercise. They had not been tired before, merely restless, and the physical exercise had made them far more comfortable.

They gathered again in the control room. All the apparatus had been taken in; the tanks were filled, and the compressed oxygen replenished. They closed the airlock and were ready to start again.

As they lifted into the air, Arcot looked at the lake that was shrinking below them. "Nice place for a picnic; we'll have to remember that place. It isn't more than twenty million light years from home."

"Yes," agreed Morey, "it is handy. But suppose we find out where home is first; let's go find the local inhabitants."

"Excellent idea. Which way do we go to look?" Wade asked.

"This lake must have an outlet to the sea," Morey answered. "I suggest we follow it. Most rivers of any size have a port near the mouth, and a port usually means a city."

"Let's go," said Arcot, swinging the shining ship about and heading smoothly down along the line of the little stream that had its beginning at the lake. They moved on across the mountains and over the green foothills until they came to a broad, rolling plain.

"I wonder if this planet is inhabited," Arcot mused. "None of this land seems to be cultivated."

Morey had been scanning the horizon with a pair of powerful binoculars. "No, the land isn't cultivated, but take a look over there—see that range of little hills over to the right? Take a look." He handed the binoculars to Arcot.

Arcot looked long and quietly. At last he lowered the binoculars and handed them to Wade, who sat next to him.

"It looks like the ruins of a city," Arcot said. "Not the ruins that a storm would make, but the ruins that high explosives would make. I'd say there had been a war and the people who once lived here had been driven off."

"So would I," rejoined Morey. "I wonder if we could find the conquerors?"

"Maybe—unless it was mutual annihilation!"

They rose a bit higher and raised their speed to a thousand miles an hour. On and on they flew, high above the gently rolling plain, mile after mile. The little brooklet became a great river, and the river kept growing more and more. Ahead of them was a range of hills, and they wondered how the river could thread its way among them. They found that it went through a broad pass that twisted tortuously between high mountains.

A few miles farther on, they came to a great natural basin in the pass, a wide, level bowl. And in almost the exact center, they saw a looming mass of buildings—a great city!

"Look!" cried Morey. "I told you it was inhabited!"

Arcot winced. "Yes, but if you shout in my ear like that again, you'll have to write things out for me for ever after." He was just as excited as Morey, nevertheless.

The great mass of the city was shaped like a titanic cone that stood half mile high and was fully a mile and a half in radius. But the remarkable thing about it was the perfect uniformity with which the buildings and every structure seemed to conform to this plan. It seemed as though an invisible, but very tangible line had been drawn in the air.

It was as though a sign had been posted: "Here there shall be buildings. Beyond this line, no structure shall extend, nor any vehicle go!"

The air directly above the city was practically packed with slim, long, needle-like ships of every size—from tiny private ships less than fifteen feet long to giant freighters of six hundred feet and longer. And every one of them conformed to the rule perfectly!

Only around the base of the city there seemed to be a slight deviation. Where the invisible cone should have touched the ground, there was a series of low buildings made of some dark metal, and all about them the ground appeared scarred and churned.

"They certainly seem to have some kind of ray screen over that city," Morey commented. "Just look at that perfect cone effect and those low buildings are undoubtedly the projectors."

Arcot had brought the ship to a halt as he came through the pass in the mountain. The shining hull was in the cleft of the gorge, and was, no doubt, quite hard to see from the city.

Suddenly, a vagrant ray of the brilliant sun reached down through a break in the overcast of clouds and touched the shining hull of the Ancient Mariner with a finger of gold. Instantly, the ship shone like the polished mirror of a heliograph.

Almost immediately, a low sound came from the distant city. It was a pulsing drone that came through the microphone in a weird cadence; a low, beating drone, like some wild music. Louder and stronger it grew, rising in pitch slowly, then it suddenly ended in a burst of rising sound—a terrific whoop of alarm.

As if by magic, every ship in the air above the city shot downward, dropping suddenly out of sight. In seconds, the air was cleared.

"It seems they've spotted us," said Arcot in a voice he tried to make nonchalant.

A fleet of great, long ships was suddenly rising from the neighborhood of the central building, the tallest of the group. They went in a compact wedge formation and shot swiftly down along the wall of the invisible cone until they were directly over the low building nearest the Ancient Mariner. There was a sudden shimmer in the air. In an instant, the ships were through and heading toward the Ancient Mariner at a tremendous rate.

They shot forward with an acceleration that was astonishing to the men in the spaceship. In perfect formation, they darted toward the lone, shining ship from far-off Earth!

XIV

The four earthmen watched the fleet of alien ships roar through the air toward them.

"Now how shall we signal them?" asked Morey, also trying to be nonchalant, and failing as badly as Arcot had.

"Don't try the light beam method," cautioned Arcot. The last time they had tried to use a light beam signal was when they first contacted the Nigrans. The Nigrans thought it was some kind of destruction ray. That had started the terrible destructive war of the Black Star.

"Let's just hang here peaceably and see what they do," Arcot suggested.

Motionless, the Ancient Mariner hung before the advancing attack of the great battle fleet. The shining hull was a thing of beauty in the golden sunlight as it waited for the advancing ships.

The alien ships slowed as they approached and spread out in a great fan-shaped crescent.

Suddenly, the Ancient Mariner gave a tremendous leap and hurtled toward them at a terrific speed, under an acceleration so great that Arcot was nearly hurled into unconsciousness. He would have been except for the terrific mass of the ship. To produce that acceleration in so great a mass, a tremendous force was needed, a force that even made the enemy fleet reel under its blow!

But, sudden as it was, Arcot had managed to push the power into reverse, using the force of the molecular drive to counteract the attraction the aliens had brought to bear.

The whole mighty fabric of the ship creaked as the titanic load came upon it. They were using a force of a million tons!

The mighty lux beams withstood the stress, however, and the ship came to a halt, then was swiftly backing away from the alien battle fleet.

"We can give them all they want!" said Arcot grimly. He noticed that Wade and Fuller had been knocked out by the sudden blow, but Morey, though slightly groggy, was still in possession of his senses.

"Let's not," Morey remonstrated. "We may be able to make friends with them, but not if we kill them off."

"Right!" replied Arcot, "but we're going to give them a little demonstration of power!"

The Ancient Mariner leaped suddenly upward with a speed that defied the eyes of the men at the rays of the enemy ships. Then, as they turned to follow the sudden motion of the ship—it was not there!

The Ancient Mariner had vanished!

Morey was startled for an instant as the ship and his companions disappeared around him, then he realized what had happened. Arcot had used the invisibility apparatus!

Arcot turned and raced swiftly far off to one side, behind the strange ships, and hovered over the great cliff that made the edge of the cleft that was the river bed. Then he snapped the ship into full visibility.

Wade and Fuller had recovered by now, and Arcot started barking out orders. "Wade—Fuller—take the molecular ray, Wade, and tear down that cliff—throw it down into the valley. Fuller, turn the heat beams on with all the power you can get and burn that refuse he tears down into a heap of molten lava!

"I'm going to show them what we can do! And, Wade—after Fuller gets it melted down, throw the molten lava high in the air!"

From the ship, a long pencil of rays, faintly violet from the air they ionized, reached out and touched the cliff. In an instant, it had torn down a vast mass of the solid rock, which came raining down into the valley with a roaring thunder and threw the dirt of the valley into the air like splashed mud.

Then the violet ray died, and two rays of blinding brilliance reached out. The rock was suddenly smoking, steaming. Then it became red, dull at first, then brighter and brighter. Suddenly it collapsed into a great pool of white-hot lava, flowing like water under the influence of the beams from the ship.

Again the pale violet of the molecular beams touched the rock—which was now bubbling lava. In an instant, the great mass of flaming incandescent rock was flying like a glowing meteor, up into the air. It shot up with terrific speed, broke up in mid-air, and fell back as a rain of red-hot stone.

The bright rays died out, but the pale fingers of the molecular beams traced across the level ground. As they touched it, the solid soil spouted into the air like some vast fountain, to fall back as frost-covered powder.

The rays that had swung a sun into destruction were at work! What chance had man, or the works of
