"The second thing we need," Arcot continued, "is information. We became lost in s.p.a.ce and are unable to find our way home. I would like to explain the case to the Astronomer."

The Astronomer proved to be a man of powerful intelligence as well as powerful physique, and was a better transmitter than receiver. It took every bit of Arcot's powerful mind to project his thoughts to the man.

He explained the dilemma that he and his friends were in, and told him how he could recognize the Galaxy on his plates. The Astronomer said he thought he knew of such a nebula, but he would like to compare his own photographs with Arcot's to make sure.

"In return," Arcot told him, "we will give you another weapon--a weapon, this time, to defeat the astronomer's greatest enemy, distance. It is an electrical telescope which will permit you to see life on every planet of this system. With it, you can see a man at a distance ten times as great as the distance from Nansal to your sun!"

Eagerly, the Astronomer questioned Arcot concerning the telectroscope, but others were clamoring for Arcot's attention.

The Biologist was foremost among the contenders; he seemed worried about the possibility of the alien Earthmen carrying pathogenic bacteria.

"Torlos has told us that you have an entirely different internal organization. What is it that is different? I can't believe that he has correctly understood you."

Arcot explained the differences as carefully as possible. By the time he was finished, the Biologist felt sure that any such creature was sufficiently far removed from them to be harmless biologically, but he wanted to study the Man of Earth further.

Arcot had brought along a collection of medical books as a possible aid in case of accident. He offered to give these to Nansal in exchange for a collection of Nansalian medical texts. The English would have to be worked out with the aid of a dictionary and a primary working aid which Arcot would supply. Arcot also asked for a skeleton to take with him, and the Biologist readily agreed.

"We'd like to give you one in return," Arcot grinned, "But we only brought four along, and, unfortunately, we are using them at the moment."

The Biologist smiled back and a.s.sured him that they would not think of taking a piece of apparatus so vitally necessary to the Earthmen.

The Military Leader was the man who demanded attention next. Arcot had a long conference with him, and they decided that the best way for the Military Leader to learn the war potential of the _Ancient Mariner_ was to personally see a demonstration of its powers.

The Council decided that the Three would go on the trip. The Military Commander picked two of his aides to go, and the Scientist picked the Astronomer and the Physicist. The head of Business and Manufacturing declined to bring any of his advisors.

"We would learn nothing," he told Arcot, "and would only be in the way.

I, myself, am going only because I am one of the Three."

"Very well," said Arcot. "Let's get started."

XXI

The party descended to the ground floor and walked out to the ship. They filed into the airlock, and in the power room they looked in amazement at the tiny machines that ran the ship. The long black cylinder of the main power unit for the molecular drive looked weak and futile compared to the bulky machines that ran their own ships. The power storage coils, with their fields of intense, dead blackness, interested the Physicist immensely.

The ship was a constant source of wonder to them all. They investigated the laboratory and then went up to the second floor. Morey and Fuller greeted them at the door, and each of the four Earthmen took a group around the ship, explaining as they went.

The library was a point of great interest, exceeded only by the control room. Arcot found some difficulty in taking care of all his visitors; there were only four chairs in the control room. The Three could sit down, but Arcot needed the fourth chair to pilot the ship. The rest of the party had to hold on as best they could, which was not too difficult for men of such physical strength; they were accustomed to high accelerations in their elevators.

Morey, Wade, and Fuller strapped themselves into the seats at the ray projectors at the sides and stern.

Arcot wanted to demonstrate the effectiveness of the ship's armament first, and then the maneuverability. He picked a barren hillside for the first demonstration. It was a great rocky cliff, high above the timber line, towering almost vertically a thousand feet above them.

Wade triggered his molecular projector, and a pale beam reached out toward the cliff. Instantly, the cliff leaped ten miles into the air, whining and roaring as it shot up through the atmosphere. Then it started to fall. Heated by its motion through the air, it struck the mountaintop as a ma.s.s of red hot rock which shattered into fragments with a terrific roar! The rocks rolled and bounced down the mountainside, their path traced by a line of steam clouds.

Then, at Arcot's order, the heat beams were all turned on the mountain at full power. In less than a minute, the peak began to melt, sending streamers of lava down the sides. The beams began to eat out a crater in the center, where the rock began to boil furiously under the terrific energy of the heat beams.

Then Arcot shut off the heat beams and turned on the molecular ray.

The molecules of the molten rock were traveling at high velocities--the heat was terrific. Arcot could see that the rock was boiling quite freely. When the molecular beam hit it, every one of those fast moving molecules shot upward together! With the roar of a meteor, it plunged toward s.p.a.ce at five miles a second!

It had dropped to absolute zero when the beam hit it, but at that speed through the air, it didn't stay cold long! Arcot followed it up in the _Ancient Mariner_. It was going too slowly for him. The air had slowed it down and heated it up, so Arcot hit it with the molecular ray again, converting the heat back into velocity.

By the time they reached free s.p.a.ce, Arcot had maneuvered the lump of rock into an orbit around the planet.

"Tharlano," he thought at the Astronomer, "your planet now has a new satellite!"

"So I perceive!" replied Tharlano. "Now that we are in s.p.a.ce, can we use the instrument you told me of?"

Arcot established the ship in an orbit twenty thousand miles from the planet and led them back to the observatory, where Morey had already trained the telectroscope on the planet below. There wasn't much to see; the amplification showed only the rushing ground moving by so fast that the image blurred.

He turned it to Sator. It filled the screen as they increased the power, but all they could see was billowing clouds. Another poor subject.

Morey showed Tharlano, the Astronomer, how to use the controls, and he began to sweep the sky with the instrument, greatly pleased with its resolving ability and tremendous magnification.

The Military Leader of the Three pointed out that the Satorians still had a weapon that was reported deadly, and they were in imminent danger unless Arcot's inventions were applied at once. All the way back to Nansal, they spent the time discussing the problem in the _Ancient Mariner_'s Library.

It was finally agreed that the necessary plans and blueprints were to be given to the Nansalians, who could start production at once. The biggest problem was in the supply of lux and relux, which, because of their vast energy-content, required the atomic converters of the _Ancient Mariner_ to make them. The Earthmen agreed to supply the power and the necessary materials to begin operations.

When the ship landed, a meeting of the manufacturers was called. Fuller distributed prints of the microfilmed plans for the equipment that he had packed in the library, and the factory engineers worked from them to build the necessary equipment.

The days that followed were busy days for Earthmen and Nansalians alike.

The Nansalians were fearful of the consequences of the weapon that the Satorians were rumored to have. The results of their investigations through their agents had, so far, resulted only in the death of the secret service men. All that was known was exactly what the Satorians wanted them to know; the instrument was new, and it was deadly.

On the other hand, the Satorians were not entirely in the dark as to the progress of Nansal, as Arcot and Morey discovered one day.

After months of work designing and tooling up the Nansalian factories, making the tools to make the tools to make the war material needed, and training the engineers of Nansal all over the planet to produce the equipment needed, Arcot and Morey finally found time to take a few days off.

Tharlano had begun a systematic search of the known nebulae, comparing them with the photographs the Earthmen had given him, and looking for a galaxy with two satellite star clouds of exactly the right size and distance from the great spiral.

After months of work, he had finally picked one which filled the bill exactly! He invited Arcot and Morey to the observatory to confirm his findings.

The observatory was located on the barren peak of a great mountain more than nine miles high. It was almost the perfect place for an astronomical telescope. Here, well above the troposphere, the air was thin and always clear. The solid rock of the mountain was far from disturbing influences which might cause any vibration in the telescope.

The observatory was accessible only from a s.p.a.ceship or air flyer, and, at that alt.i.tude, had to be pressurized and sealed against the thin, cold air outside. Within, the temperature was kept constant to a fraction of a degree to keep thermal expansion from throwing the mirror out of true.

Arcot and Morey, accompanied by Tharlano and Torlos, settled the _Ancient Mariner_ to the landing field that had been blasted out of the rock of the towering mountain. They went over to the observatory and were at once admitted to the airlock.

The floor was of smoothed, solid rock, and in this, the great clock which timed and moved the telescope was set.

The entire observatory was, of course, surrounded by a magnetic shield, and it was necessary to make sure there were no enemy ships around before using the telescope, because the magnetic field affected the light rays pa.s.sing through it.

The mirror for the huge reflecting telescope was nearly three hundred inches in diameter, and was powerful enough to spot a s.p.a.ceship leaving Sator. Its military usefulness, however, was practically nil, since painting the ships black made them totally invisible.
