power around them.

As a guide, Arcot used the compass gyroscope, the only one not twisted far out of its original position; with it, he managed to steer a fairly straight course.

Meanwhile, in the power room, Wade and Morey were working frantically to get the space-strain drive coil recharged. Despite the strength-sapping strain of working under four gravities of acceleration, they managed to get the auxiliary power unit into operation. In a few moments, they had it pouring its energies into the coil-bank so that they could charge up the central drive coil.

Another silver bar fuse was inserted, and Wade checked the relays to make sure they were in working order.

Fuller, who had regained consciousness, worked his way laboriously down to the power room carrying three space-suits. He had stopped in the lab to get the power belts, and the three men quickly donned them to help them overcome the four-gravity pull.

Another half hour sped by as the bucking ship forced its way through the terrific field in space.

Suddenly they felt a terrific jolt again—then the ship was moving more smoothly, and gradually it was calm. They were through!

"Have we got power for the space-strain drive yet?" Arcot called through the intercom.

"Enough," Morey cried. "Try it!"

Arcot cut off the molecular motion drive, and threw in all the space-control power he had. The ship was suddenly supercharged with energy. It jarred suddenly—then was quiet. He allowed ten minutes to pass, then he cut off the drive and allowed the ship to go into free fall.

Morey's voice came over the intercom. "Arcot, things are really busted up down here! We had to haywire half the drive together."

"I'll be right down. Every instrument on the ship seems to be out of kilter!"

It was a good thing they had plenty of spare parts; some of the smaller relays had burned out completely, and several of the power leads had fused under the load that had been forced through them.

The space-strain drive had been leaking energy at a terrific rate; without further repair, it could not function much longer.

In the power room, Arcot surveyed the damage. "Well, boys, we'd better get to work. We're stranded here until we get that drive repaired!"

Forty hours later, Arcot was running the ship smoothly at top speed once again. The four men had gone to bed after more than thirty hours of hard work. That, coupled with the exhaustion of working under four gravities, as they had while the ship was going through the storm, was enough to make them sleep soundly.

Arcot had awakened before the others and had turned on the drive after resetting their course.

After that was done, there was little to do, and time began to hang heavily on Arcot's hands. He decided to make a thorough inspection of the hull when the others awoke. The terrific strain might have opened cracks in the lux metal hull that would not be detectable from the inside because the inner wall was separated from the outer envelope.

Accordingly, he got out the spacesuits, making sure the oxygen tanks were full and all was ready. Then he went into the library, got out some books, and set about some calculations he had in mind.

When Morey woke, some hours later, he found Arcot still at work on his calculations.

"Hey!" he said, swinging himself into the chair beside Arcot, "I thought you'd be on the lookout for more cosmic rays!"

"Curious delusion, wasn't it?" asked Arcot blandly. "As a matter of fact, I've been busy doing some figuring. I think our chance of meeting another such region is about one in a million million million million. Considering those chances, I don't think we need to worry. I don't see how we ever met one—but the chances of hitting one are better than hitting two."

Just then Fuller stuck his head in the door.

"Oh," he said, "so you're at it already? Well, I wonder if one of you could tell me just what it was we hit? I've been so busy I haven't had a chance to think."

"Don't take the chance now, then," grinned Morey. "You might strain your brain."

"Please!" Fuller pleaded, wincing. "Not before breakfast. Just explain what that storm was."

"We simply came to a region in space where cosmic rays are created," explained Arcot.

Fuller frowned. "But there's nothing out here to generate cosmic rays!"

Arcot nodded. "True. I think I know their real source, but I believe I'll merely say they are created here. I want to do more work on this. My idea for an energy source greater than any other in the universe has been confirmed.

"At any rate, they are created in that space, a perfect vacuum, and the space there is distorted terrifically by the titanic forces at work. It is bent and twisted far out of the normal, even curvature, and it was that bumpy spot in space that threw us about so.

"When we first entered, using the space-strain drive, the space around the ship, distorted as it was, conflicted with the region of the cosmic ray generation and the ship lost out. The curvature of space that the ship caused was sometimes reinforced and sometimes cancelled out by the twisted space around it, and the tremendous surges of current back and forth from the main power coil to the storage coils caused the electric discharges that kept burning through the air. I notice we all got a few burns from that. The field was caused by the terrific surges of current, and that magnetic field caused the walls of the ship to heat up due to the generation of electric current in the walls."

Fuller looked around at the walls of the ship. "Well, the Ancient Mariner sure took a beating."

"As a matter of fact, I was worried about that," said Arcot. "Strong as that hull is, it might easily have been strained in that field of terrific force. If it happened to hit two 'space waves' at once, it might have given it an acceleration in two different directions at once, which would strain the walls with a force amounting to thousands of tons. I laid out the suits up front, and I think we might reasonably get out there and take a look at the old boat. When Wade gets up—well, well—speak of the devil! My, doesn't he look energetic?"

Wade's huge body was floating in through the library door. He was yawning sleepily and rubbing his eyes. It was evident he had not yet washed, and his growing beard, which was heavy and black on his cheeks, testified to his need for a shave. The others had shaved before coming into the library.

"Wade," said Arcot, "we're going outside, and we have to have someone in here to operate the airlock. Suppose you get to work on the hirsute adornment; there's an atomic hydrogen cutting torch down in the lab you can use, if you wish. The rest of us are going outside." Then Arcot's voice became serious. "By the way, don't try any little jokes like starting off with a little acceleration. I don't think you would—you've got good sense—but I like to make certain. If you did, we'd be left behind, and you'd never find us in the vast immensity of intergalactic space."

It wasn't a pleasant idea to contemplate. Each of the suits had a radio for communication with each other and with the ship, but they would only carry a few hundred miles. A mere step in space!

Wade shook his head, grinning. "I have no desire to be left all by myself on this ship, thank you. You don't need to worry."

A few minutes later, Arcot, Morey, and Fuller stepped out of the airlock and set to work, using power flashlights to examine the outer hull for any signs of possible strain.

The flashlights, equipped as they were with storage coils for power, were actually powerful searchlights, but in the airlessness of space, the rays were absolutely invisible. They could only be seen when they hit the relux inner wall at such an angle that they were reflected directly into the observer's eyes. The lux metal wall, being transparent, was naturally invisible, and the smooth relux, reflecting one hundred percent of the incident light, did not become illuminated, for illumination is the result of the scattering of light.

It was necessary to look closely and pass the beams over every square inch of the surface. However, a crack would be rough, and hence would scatter light and be even more readily visible than otherwise.

To their great relief, after an hour and a half of careful inspection, none of them had found any signs of a crack, and they went back into the ship to resume the voyage.

Again they hurled through space, the twin ghost ships following them closely. Hour after hour the ship went on. Now they had something else to do. They were at work calculating some problems that Arcot had suggested in connection with the velocities of motion that had been observed in the stars at the edge of the island universe they were approaching. Since these stars revolved about the mass of the entire galaxy, it was possible to calculate the mass of the entire universe by averaging the values from several stars. Their results were not exact, but they were reliable enough. They found the universe to have a mass of two hundred and fifty million suns, only a little less than the home Galaxy. It was an average-sized nebula.

Still the hours dragged as they came gradually nearer their goal—gradually, despite their speed of twenty-four light years per second!

At the end of the second day after their trouble with the cosmic ray field, they stopped for observation. They were now so near the Island Universe that the stars spread out in a huge disc ahead of them.

"About three hundred thousand light years distant, I should guess," said Morey.

"We know our velocity fairly accurately," said Wade. "Why can't we calculate the distance between two of these stars and then go on in?"

"Good idea," agreed Arcot. "Take the angle, will you, Morey? I'll swing the ship."

After taking their measurements, they advanced for one hour. Knowing this distance from experience, they were able to calculate the diameter of this galaxy. It turned out to be on the order of ninety thousand light years.

They were now much closer; they seemed, indeed, on the very edge of the giant universe. The thousands of stars flamed bright below them, stretching across their horizon more and more—a galaxy the eyes of men had never before seen at such close range! This galaxy had not yet condensed entirely to stars, and in its heart there still remained the vast gas cloud that would eventually be stars and planets. The vast misty cloud was plainly visible, glowing with a milky light like some vast frosted light bulb.

It was impossible to conceive the size of the thing; it looked only like some model, for they were still over a quarter of a million light years from it.

Morey looked up from his calculations. "I think we should be there in about three hours. Suppose we go at full speed for about two hours and then change to low speed?"

"You're the astronomical boss, Morey," said Arcot. "Let's go!"

They swung the ship about once more and started again. As they drew nearer to this new universe, they began to feel more interest in the trip. Things were beginning to happen!

The ship plunged ahead at full speed for two hours. They could see nothing at that velocity except the two ghost ships that were their ever-present companions. Then they stopped once more.

About them, they saw great suns shining. One was so close they could see it as a disc with the naked eye. But they could not see clearly; the entire sky was misty and the stars that were not close were blotted out. The room seemed to grow warm.

"Hey! Your calculations were off!" called Arcot. "We're getting out of here!"

Suddenly the air snapped and they were traveling at low speed under the drive of the space-strain apparatus. The entire space about them was lit with a dim violet glow. In ten minutes, the glow was gone and Arcot cut the drive.

They were out in ordinary dark space, with its star-studded blackness.

"What was the matter with my calculations?" Morey wanted to know.

"Oh, nothing much," Arcot said casually. "You were only about thirty thousand light years off. We landed right in the middle of the central gas cloud, and we were plowing through it at a relative velocity of around sixteen thousand miles per second! No wonder we got hot!

"We're lucky we didn't come near any stars in the process; if we had, we could have had to recharge the coil."

"It's a wonder we didn't burn up at that velocity," said Fuller.

"The gas wasn't dense enough," Arcot explained. "That gas is a better vacuum than the best pump could give you on Earth; there are fewer molecules
