"So that you're dark-skinned and we light?" "No, that's unimportant. Totally superficial variations, color and eye-structure and all that. No, the difference is on a lower level, and is very small—one molecule in the hereditary chain," Wattock said with relish, warming to his lecture. "It causes no major divergence from the Common Hominid Type in you hilfs; so the first colonists wrote, and they knew. But it means that we can't interbreed with you; or digest local organic food without help; or react to your viruses... . Though as a matter of fact, this enzymoid business is a bit overdone. Part of the effort to do exactly as the First Generation did.
Pure superstition, some of that. I've seen people come hi from long hunting-trips, or the Atlantika refugees last Spring, who hadn't taken an enzy^ moid shot or pill for two or three moonphases, but weren't failing to digest. Life tends to adapt, after all." As he said this Wattock got a very odd expression, and stared at her. She felt guilty, since she had no idea what he had been explaining to her: none of the key words were words in her language. "Life what?" she inquired timidly.
"Adapts. Reacts. Changes! Given enough pressure, and enough generations, the favorable adaptation tends to prevail... . Would the solar radiation work in the long run towards a sort of local biochemical norm ... all the stillbirths and miscarriages then would be overadaptations or maybe incompatibility between the mother and a normalized fetus ..." Wattock stopped waving his scissors and bent to his work again, but in a moment he was looking up again in his unseeing, intense way and muttering, "Strange, strange, strange! ... That would imply, you know, that cross-fertilization might take place."
"I listen again," Rollery murmured.
"That men and hilfs could breed together!" This she understood at last, but did not understand whether he said it as a fact or a wish or a dread. "Elder, I am too stupid to hear you," she said.
"You understand him well enough," said a weak voice nearby: Pilotson Alterra, lying awake. "So you think we've finally turned into a drop in the bucket, Wattock?" Pilotson had raised up on his elbow. His dark eyes glittered in his gaunt, hot, dark face.
"If you and several of the others do have infected wounds, then the fact's got to be explained somehow."
"Damn adaptation then. Damn your crossbreeding and fertility!" the sick man said, and looked at Rolery. "So long as we've bred true we've been Man. Exiles, Alterrans, humans. Faithful to the knowledge and the Laws of Man. Now, if we can breed with the hilfs, the drop of our human blood will be lost before another Year's past. Diluted, thinned out to nothing. Nobody will set these instruments, or read these books. Jakob Agat's grandsons will sit pounding two rocks together and yelling, till the end of time ... Damn you stupid barbarians, can't you leave men alone— alone!"
He was shaking with fever and fury. Old Wattock, who had been fiddling with one of his little hollow darts, filling it up, now reached over in his smooth doctorly way and shot poor Pilotson in the forearm. "Lie down, Huru," he said, and with a puzzled expression the wounded man obeyed. "I don't care if I die of your filthy infections," he said in a thickening voice, "but your filthy brats, keep them away from here, keep 'em out of the ... out of the City ..."
"That'll hold him down a while," Wattock said, and sighed. He sat hi silence while Rolery went on preparing bandages. She was deft and steady at such work. The old doctor watched her with a brooding face.
When she straightened up to ease her back she saw the old man too had fallen asleep, a dark pile of skin and bones hunched up in the corner behind the table. She worked on, wondering if she had understood what he said, and if he had meant it: that she could bear Agat's son.
She had totally forgotten that Agat might very well be dead already, for all she knew. She sat there among the sleep of wounded men, under the ruined city full of death, and brooded speechlessly on the chance of life.
CHAPTER FOURTEEN: The First Day
THE COLD gripped harder as night fell. Snow that had thawed in sunlight froze as slick ice.
Concealed on nearby roofs or in attics, the Gaal shot over their pitch-tipped arrows that arched red and gold like birds of fire through the cold twilit air. The roofs of the four beleaguered buildings were of copper, the walls of stone; no fire caught. The attacks on the barricades ceased, no more arrows of iron or fire were shot. Standing up on the barricade, Jakob Agat saw the darkening streets slant off empty between dark houses.
At first the men in the Square waited for a night attack, for the Gaal were plainly desperate; but it grew colder, and still colder. At last Agat ordered that only the minimum watch be kept, and let most of the men go to get their wounds looked after, and get food and rest. If they were exhausted, so must the Gaal be, and they at least were clothed against this cold while the Gaal were not. Even desperation would not drive the northerners out into this awful, starlit clarity, in their scant rags of fur and felt. So the defenders slept, many at their posts, huddled hi the halls and by the windows of warm buildings. And the besiegers, without food, pressed around campfires built in high stone rooms; and their dead lay stiff-limbed hi the ice-crusted snow below the barricades. Agat wanted no sleep. He could not go inside the buildings, leaving the Square where all day long they had fought for their lives, and which now lay so still under the Winter constellations. The Tree; and the Arrow; and the Track of five stars; and the Snowstar itself, fiery above the eastern roofs: the stars of Whiter. They burned like crystals hi the profound, cold blackness overhead.
He knew this was the last night—his own last night, or his city's, or the last night of battle—which one, he did not know. As the hours wore on, and the Snowstar rose higher, and utter silence held the Square and the streets around it, a kind of exultation got hold of him. They slept, all the enemies within these city walls, and it was as if he alone waked; as if the city belonged, with all its sleepers and all its dead, to him alone. This was his night.
He would not spend it locked hi a trap within a trap. With a word to the sleepy guard, he mounted the Esmit Street barricade and swung himself down on the other side. "Alterra!" someone called after him hi a hoarse whisper; he only turned and gestured that they keep a rope ready for him to get back up on, and went on, right up the middle of the street. He had a conviction of his invulnerability with which it would be bad luck to argue. He accepted it, and walked up the dark street among his enemies as if he were taking a stroll after dinner.
He passed his house but did not turn aside. Stars eclipsed behind the black roof-peaks and reappeared, their reflections glittering in the ice underfoot. Near the upper end of town the street narrowed and turned a little between houses that had been deserted since before Agat was born, and then opened out suddenly into the little square under the Land Gate. The catapults still stood there, partly wrecked and dismantled for firewood by the Gaal, each with a heap of stones beside it. The high gates themselves had been opened at one point, but were bolted again now and frozen fast. Agat climbed up the steps beside one of the gate-towers to a post on the wall; he remembered looking down from that post, just before the snow began, on the whole battle-force of the Gaal, a roaring tide of men like the seatide down on the beach. If they had had more ladders it would have all been over with that day ... Now nothing moved; nothing made any sound. Snow, silence, starlight over the slope and the dead, ice-laden trees that crowned it.
He looked back westward, over the whole City of Exile; a little clutter of roofs dropping down away from his high post to the wall over the seacliff. Above that handful of stone the stars moved slowly westward. Agat sat motionless, cold even in his clothing of leather and heavy furs, whistling a jig-tune very softly.
