For the words Lappy said, with minor variations, were Isaac Newton's Laws of Motion.

"There are the seven planets," Navel was saying gravely, "and the two lights--that is, the sun and the moon. The first planet, that nearest the sun, is called Rym. Rym is the planet of intellect, of the ordinary mind. Second, is Lyndal, the planet of love, beauty, parties, marriage, and things of a gentle nature. Third is Fors, planet of action, strife. Fourth is Bonken, planet of beneficence, of gain, money, health. Next comes Huck, orb of necessity, the Greater Infortune, which brings men most trouble of all. Then Weepen, planet of illusion, of dreamers and poets and, poorly aspected, liars and cheats. And finally there is Sharb, planet of genius, of sudden cataclysms."

"I see," Travis murmured.

"But it is not only these planets and their aspects which is important, it is also to be considered such houses and signs as through which these planets transit...."

She went on, but Travis was having difficulty following her. He could not help but return to Newton's Laws. It was incredible. Here on this backward planet, mired in an era roughly equivalent to the time of the Renaissance, an event was taking place almost exactly at the same time as it had happened, long ago, on Earth. It had been Isaac Newton, then. It was, incredibly, this frail young man named Lappy now. For unless Travis was greatly mistaken, Navel's kid brother was an authentic genius. And such a genius as comes once in a hundred years.

So, naturally, Lappy would have to come home with Travis. The boy was hardly college age as yet. Sent to school by Alls.p.a.ce, given a place in the great Alls.p.a.ce laboratories at Aldebaran, young Lappy might eventually make the loss of the contract at Mert seem puny in comparison to the things that head of his could produce. For Lappy was a natural resource, just as certainly as any mine on Mert, and since the advent of Earth science meant Mert would no longer be needing him, Lappy could go along with Travis and still leave him a clear conscience.

But the question still remained: how? He could not even get himself out, yet, let alone Lappy. And the girl. What about the girl?

He brooded, groping for an out. But in the meanwhile he listened while the girl outlined Mert's system of astrology. He had realized finally that the key to the business lay there. Astrology was these people's most powerful motivating force. If he could somehow turn it to his advantage--He listened to the girl. And eventually found his plan.

"Ho!" he said abruptly. Startled, the girl stared at him.

"Lightning in the brain," Travis grinned, "solutions effervesce.

Attend. Of surety, are not _places_ on Mert also ruled by the stars?

Is it not true that towns and villages do also have horoscopes?"

Navel blinked.

"Why, see thee, it is in the nature of things, odd man, that all matter is governed by the planets. How else come explanations, for example, of natural catastrophes, fires, plagues, which affect whole cities and not others? And consider war, does not one country win, and the other lose? Of a surety different aspects obtain...."

"Joy then," Travis said. "But do further observe. Is it not so, in your astrology, that a man's horoscope may often conflict with that of the place wherein he dwells? Is it not so that, often, a man is promised greater success in other regions, where the ruling stars more closely and friendlily conjoin his own?"

"Your mind leaps obstacles and homes to the truth," Navel said approvingly. "Many times has it been made clear that a man's fortune lies best in places ruled by his Ascendant, as witness, for example, those who are advised to take to the sea, or to southern lands...."

"Intoxication!" Travis cried out happily, "then is our goal made known. Consider: from your poor natal horoscope, in this city, this land, no fortune arises. You doom yourself, with Lappy, by remaining here. But what business is this? Seek you not better times? Could you not go forth to another place, and so become people of gravity, of substance, of moment?"

The girl regarded for a moment, puzzled, then caught his point and shook her head sadly.

"Odd man, without profit. You misconstrue. Such as we, my brother and I, are not condemned by place, but by twistings of the character. My natal Huck, retrograde in the tenth, gives an untrustworthy, criminous person. It would be so here, there, anywhere. My pattern is set. Such travels as you describe are for those who conflict only with place. I, and my brother, it is our sad fortune to conflict with _all_."

"But this is the core," Travis insisted. "The conflict is with _Mert_!

Consider, such travail as is yours stems from the radiations of Huck, of Weepen, of Scharb. But should you remove yourself beyond their reach, across great vastnesses of s.p.a.ce to where other planets subtend--and in their alien radiation extinguish and nullify those of Huck--what fortune comes then? What rises, what leaps in joy?"

The girl sat speechless, staring at Travis with great soft eyes. The boy Lappy, who until that moment had been grinning happily over the news that his laws were true, suddenly understood what Travis was saying and let his mouth fall open.

But the girl sat without expression. Then, to Travis' dismay, a slow dark look of disgust came over her face.

"This," she said ominously, "this smacks of _vetching_."

The word fell like a sudden fog. Lappy, who had begun to smile, cut it sharply off. Travis, remembering what vetching meant to these people, gathered his forces.

"Woman," he said bitingly, "you speak in offense, but with patience and kindness I heal your insult. I control my choler, but my blood flows hot, therefore fasten your tongue. Tell me not that I have overvalued you, for your brain is clear, your courage thick. Wherefore speak of vetch? What vetch is there in travel? He vetches who leaves a certainty for another certainty, who attempts to avoid his starry fate. But you go from a certain end to an end not certain at all, to places of dark mystery, of grim foreboding. It may be that you perish, or pain in the extreme, as well as gain fortune. The end is not clear.

This then is not vetching. Now retreat your words, and reply to me as one does to a friend, a companion, one who seeks your good."

He sat tautly while the girl thought it out. Eventually she dropped her eyes in submission and he sighed inwardly with relief. It was accomplished. He would have to sh.o.r.e it up perhaps with a little elaboration, but it was accomplished.

Ten minutes later he was standing free and unbound in the pa.s.sageway.

It was just barely in time. Down the round dark tunnel two men came.

Navel stopped gingerly over the bodies and gazed at Travis with awestruck admiration.

"A rare skill," she murmured, "they did flip and gyrate as dry leaves in the wind."

"Observe then," Travis said ominously, inspecting meanwhile the long slash down his arm with which Tude had nearly gotten him "and learn.

And in the future receive my words with planetary respect."

"I will."

"And I," added Lappy, shaken.

"Fair. Bright. Now attend. How lies the path?"

"Through more such as these, I fear. This place in which we trouble lies at a dead end. We must proceed through great halls where many sit waiting, ere we arrive at the light."

"No other way? Think now."

"None."

Travis sighed.

"And they talk about luck. Well boy," he turned to Lappy, "give me your blunderbuss. Obtain that one's knife"--he indicated the sleeping Tude--"and let us carve our way out into the sunshine."

But as it turned out, the getting free was much easier than he had antic.i.p.ated. There was only one band, the girl's own, between them and the opening, and these had fortunately just finished their evening meal when Travis stalked, black, gaunt and murderous, out of the tunnel into their large round room. Part of it was the surprise, part of it was the sudden knowledge that big Tude and the other man had already tried to stop him, but most of it was simply the look of him.

He was infinitely ready. They were not, had no reason to be, and they took it automatically for granted that a man this confident must have the stars behind him. They regarded him thoughtfully as he went on by.

No one moved. They were a philosophical people. When he had gone, taking the boy and girl with him, they discussed it thoroughly.

Out under the sky at last it was pitch black and the stars were shining. Travis realized that he had been in the sewer almost a full 24 hours. That meant that the eclipse was done, tomorrow would be a good day. There was not much time.

He commandeered the first carriage to come by, routing three elegantly dressed but unwarlike young men who fled in terror. He saw with relief that they thought him only another sewer rat, for if word of an Earthman robbing the local citizens ever got out there would be h.e.l.l to pay, and in addition to his other troubles he could not abide that.

He told Navel to head for the field where old 29 rested. Thoroughly bushed and beginning now to feel a woeful hunger, he sat back to brood.

At the ship young Trippe greeted him with haggard astonishment. He jumped forward joyfully.

"Trav! By jig, Trav, I thought we'd lost you. Old Dolly's over at the local police sta--" He stopped abruptly and stood slack-jawed as Navel and Lappy clambered fearfully through the lock. Travis glanced back.

No spectators. Good.

"Now what in the sweet silly name--" Trippe began, but Travis stopped him.

"Russ, be a good kid. See if you can get me something to eat. Haven't had a bite in 24 hours."
