sliding pistol grip forward and back to reload, pressing the trigger an instant later. Another arrow went its way.

By the time he had fired the tenth arrow in the magazine he was shooting at the rate of one arrow per second. On the trunk of the distant tree, like a bristle of stiff whiskers, the ten arrows were driven deep into the wood in an area no larger than the chest of a prowler or head of a unicorn.

"This is better than I hoped for," he said to George. "One man with one of these would equal six men with ordinary bows."

"I'm going to add another feature," George said. "Bundles of arrows, ten to the bundle in special holders, to carry in the quivers. To reload the magazine you'd just slap down a new bundle of arrows, in no more time than it would take to put one arrow in an ordinary bow. I figured that with practice a man should be able to get off forty arrows in not much more than twenty seconds."

George took the bow and went back in the cave to add his new feature. Humbolt stared after him, thinking, If he can make something like that out of wood and unicorn gut, what would he be able to give us if he could have metal?

Perhaps George would never have the opportunity to show what he could do with metal. But Humbolt already felt sure that George's genius would, if it ever became necessary, make possible the alternate plan for leaving Ragnarok.

The weeks dragged into months and at last enough snow was gone from the Craigs that Humbolt and Dan Barber could start. They met no opposition. The prowlers had long since disappeared into the north and the unicorns were very scarce. They had no occasion to test the effectiveness of the new automatic crossbows in combat; a lack of opportunity that irked Barber.

"Any other time, if we had ordinary bows," he complained, "the unicorns would be popping up to charge us from all directions."

"Don't fret," Humbolt consoled him. "This fall, when we come back, they will be."

They reached the mountain and stopped near its foot where a creek came down, its water high and muddy with melting snows. There they hunted until they had obtained all the meat they could carry. They would see no more game when they went up the mountain's canyons. A poisonous weed replaced most of the grass in all the canyons and the animals of Ragnarok had learned long before to shun the mountain.

They found the canyon that Craig and his men had tried to explore and started up it. It was there that Craig had discovered the quartz and mica and so far as he had been able to tell the head of that canyon would be the lowest of all the passes over the mountain.

The canyon went up the mountain diagonally so that the climb was not steep although it was constant. They began to see mica and quartz crystals in the creek bed and at noon on the second day they passed the last stunted tree. Nothing grew higher than that point but the thorny poison weeds and they were scarce.

The air was noticeably thinner there and their burdens heavier. A short distance beyond they came to a small rock monument; Craig's turn-back point.

The next day they found the quartz crystals in place. A mile farther was the vein the mica had come from. Of the other minerals Craig had hoped to find, however, there were only traces.

The fourth day was an eternity of struggling up the now-steeper canyon under loads that seemed to weigh hundreds of pounds; forcing their protesting legs to carry them fifty steps at a time, at the end of which they would stop to rest while their lungs labored to suck in the thin air in quick, panting breaths.

It would have been much easier to have gone around the mountain. But the Chasm was supposed to be like a huge cavity scooped out of the plateau beyond the mountain, rimmed with sheer cliffs a mile high. Only on the p. 75 side next to the mountain was there a slope leading down into it.

They stopped for the night where the creek ended in a small spring. There the snow still clung to the canyon's walls and there the canyon curved, offering them the promise of the summit just around the bend as it had been doing all day.

The sun was hot and bright the next morning as they made their slow way on again. The canyon straightened, the steep walls of it flattening out to make a pair of ragged shoulders with a saddle between them.

They climbed to the summit of the saddle and there, suddenly before them, was the other side of the world—and the Chasm.

Far below them was a plateau, stretching endlessly like the one they had left behind them. But the chasm dominated all else. It was a gigantic, sheer-walled valley, a hundred miles long by forty miles wide, sunk deep in the plateau with the tops of its mile-high walls level with the floor of the plateau. The mountain under them dropped swiftly away, sloping down and down to the level of the plateau and then on, down and down again, to the bottom of the chasm that was so deep its floor was half hidden by the morning shadows.

"My God!" Barber said. "It must be over three miles under us to the bottom, on the vertical. Ten miles of thirty-three per cent grade—if we go down we'll never get out again."

"You can turn back here if you want to," Humbolt said.

"Turn back?" Barber's red whiskers seemed to bristle. "Who in hell said anything about turning back?"

"Nobody," Humbolt said, smiling a little at Barber's quick flash of anger.

He studied the chasm, wishing that they could have some way of cutting the quartz crystals and making binoculars. It was a long way to look with the naked eye....

Here and there the chasm thrust out arms into the plateau. All the arms were short, however, and even at their heads the cliffs were vertical. The morning shadows p. 76 prevented a clear view of much of the chasm and he could see no sign of the red-stained strata that they were searching for.

In the southwest corner of the chasm, far away and almost imperceptible, he saw a faint cloud rising up from the chasm's floor. It was impossible to tell what it was and it faded away as he watched.

Barber saw it, too, and said, "It looked like smoke. Do you suppose there could be people—or some kind of intelligent things—living down there?"

"It might have been the vapor from hot springs, condensed by the cool morning air," he said. "Whatever it was, we'll look into it when we get there."

The climb down the steep slope into the chasm was swifter than that up the canyon but no more pleasant. Carrying a heavy pack down such a grade exerted a torturous strain upon the backs of the legs.

The heat increased steadily as they descended. They reached the floor of the valley the next day and the noonday heat was so great that Humbolt wondered if they might not have trapped themselves into what the summer would soon transform into a monstrous oven where no life at all could exist. There could never be any choice, of course—the mountains were passable only when the weather was hot.

The floor of the valley was silt, sand and gravel—they would find nothing there. They set out on a circuit of the chasm's walls, following along close to the base.

In many places the mile-high walls were without a single ledge to break their vertical faces. When they came to the first such place they saw that the ground near the base was riddled with queer little pits, like tiny craters of the moon. As they looked there was a crack like a cannon shot and the ground beside them erupted into an explosion of sand and gravel. When the dust had cleared away there was a new crater where none had been before.

Humbolt wiped the blood from his face where a flying fragment had cut it and said, "The heat of the sun loosens rocks up on the rim. When one falls a mile in a one point five gravity, it's traveling like a meteor."

p. 77

They went on, through the danger zone. As with the peril of the chasm's heat, there was no choice. Only by observing the material that littered the base of the cliffs could they know what minerals, if any, might be above them.

On the fifteenth day they saw the red-stained stratum. Humbolt quickened his pace, hurrying forward in advance of Barber. The stratum was too high up on the wall to be reached but it was not necessary to examine it in place—the base of the cliff was piled thick with fragments from it.

He felt the first touch of discouragement as he looked at them. They were a sandstone, light in weight. The iron present was only what the Dunbar Expedition had thought it to be; a mere discoloration.

They made their way slowly along the foot of the cliff, examining piece after piece in the hope of finding something more than iron stains. There was no variation, however, and a mile farther on they came to the end of the red stratum. Beyond that point the rocks were gray, without a vestige of iron.

"So that," Barber said, looking back the way they had come, "is what we were going to build a ship out of—iron stains!"

Humbolt did not answer. For him it was more than a disappointment. It was the death of a dream he had held since the year he was nine and had heard that the Dunbar Expedition had seen iron-stained rock in a deep chasm—the only iron-stained rock on the face of Ragnarok. Surely, he had thought, there would be enough iron there to build a small ship. For eleven years he had worked toward the day when he would find it. Now, he had found it—and it was nothing. The ship was as far away as ever....

But discouragement was as useless as iron-stained sandstone. He shook it off and turned to Barber.

"Let's go," he said. "Maybe we'll find something by the time we circle the chasm."

For seven days they risked the danger of death from downward plunging rocks and found nothing. On the eighth day they found the treasure that was not treasure.

p. 78

They stopped for the evening just within the mouth of one of the chasm's tributaries. Humbolt went out to get a drink where a trickle of water ran through the sand and as he knelt down he saw the flash of something red under him, almost buried in the sand.

He lifted it out. It was a stone half the size of his hand; darkly translucent and glowing in the light of the setting sun like blood.

It was a ruby.

He looked, and saw another gleam a little farther up the stream. It was another ruby, almost as large as the first one. Near it was a flawless blue sapphire. Scattered here and there were smaller rubies and sapphires, down to the size of grains of sand.

He went farther upstream and saw specimens of still another stone. They were colorless but burning with internal fires. He rubbed one of them hard across the ruby he still carried and there was a gritting sound as it cut a deep scratch in the ruby.

"I'll be damned," he said aloud.

There was only one stone hard enough to cut a ruby—the diamond.

It was almost dark when he returned to where Barber was resting beside their packs.

"What did you find to keep you out so late?" Barber asked curiously.

He dropped a double handful of rubies, sapphires and diamonds at Barber's feet.

"Take a look," he said. "On a civilized world what you see there would buy us a ship without our having to lift a finger. Here they're just pretty rocks.

"Except the diamonds," he added "At least we now have something to cut those quartz crystals with."

They took only a few of the rubies and sapphires the next morning but they gathered more of the diamonds, looking in particular for the gray-black and ugly but very hard and tough carbonado variety. Then they resumed their circling of the chasm's walls.

The heat continued its steady increase as the days p. 79 went by. Only at night was there any relief from it and the nights were growing swiftly shorter as the blue sun rose earlier each morning. When the yellow sun rose the chasm became a blazing furnace around the edge of which they crept like ants in some gigantic oven.

There was no life in any form to be seen; no animal or bush or blade of grass. There was only the barren floor of the chasm, made a harsh green shade by the two suns and writhing and undulating with heat waves like a nightmare sea, while above them the towering cliffs shimmered, too, and sometimes seemed to
