Changes were taking place; they could not be ignored. The whole of Ern's class lived at the surface, breathing air. Infected by some pale dilution of Ern's curiosity, they stared uneasily landward. Sexual differentiation was evident; there were tendencies toward sexual play, from which the double-crested children, with undeveloped organs, stood contemptuously aloof. Social as well as physical distinctions developed; there began to be an interchange of taunts and derogation, occasionally a brief skirmish. Ern ranged himself with the double-crested children, although on exploring his own scalp, he found only indecisive hummocks and hollows, which to some extent embarrassed him.

In spite of the general sense of imminence, the coming of the men took the children by surprise.

In the number of two hundred the men came down the sloughs and swam out to surround the shallows. Ern and a few others instantly clambered up among the reeds of the island and concealed themselves. The other children milled and swam in excited circles. The men shouted, slapped the water with their arms; diving and veering, they herded the water-childien up the slough, all the way to the beach of dried mud. Here they chose and sorted, sending the largest up the beach, allowing the fingerlings and sprats to return to the shallows, taking the double-crested children with sharp cries of exultation.

The selection was complete. The captive children were marshaled into groups and sent staggering up the trail; those with legs still soft were carried.

Ern, fascinated by the process, watched from a discreet distance. When men and children had disappeared, he emerged from the water, clambered up the beach to look after his departed friends. What to do now? Return to the shallows? The old life seemed drab and insipid. He dared not present himself to the men. They were single-crested; they were harsh and abrupt. What remained? He looked back and forth, between water and land, and at last gave his youth a melancholy farewell: henceforth he would live ashore.

He walked a few steps up the path, stopped to listen.

Silence.

He proceeded warily, prepared to duck into the undergrowth at a sound. The soil underfoot became less sodden; the reeds disappeared and aromatic black cycads lined the path. Above rose slender supple withes, with gas-filled leaves half-floating, half-supported. Ern moved ever more cautiously, pausing to listen ever more frequently. What if he met the men? Would they kill him? Ern hesitated and even looked back along the path ... The decision had been made. He continued forward.

A sound, from somewhere not too far ahead. Ern dodged off the path, flattened himself behind a hummock.

No one appeared. Ern moved forward through the cycads and, presently, through the black fronds, he saw the village of the men: a marvel of ingenuity and complication! Nearby stood tall bins containing food-stuffs, then, at a little distance, a row of thatched stalls stacked with poles, coils of rope, pots of pigment and grease. Yellow tinkle-birds, perched on the gables, made a constant chuckling clamor. The bins and stalls faced an open space surrounding a large platform, where a ceremony of obvious import was in progress. On the platform stood four men, draped in bands of woven leaves and four women wearing dark red shawls and tall hats decorated with tinkle-bird scales. Beside the platform, in a miserable gray clot, huddled the single-crested children, the individuals distinguishable only by an occasional gleam of eye or twitch of pointed crest.

One by one the children were lifted up to the four men, who gave each a careful examination. Most of the male children were dismissed and sent down into the crowd. The rejects, about one in every ten, were killed by the blow of a stone mallet and propped up to face the wall of storm. The girl-children were sent to the other end of the platform, where the four women waited. Each of the trembling girl-children was considered in turn. About half were discharged from the platform into the custody of a woman and taken to a booth; about one in every five was daubed along the skull with white paint and sent to a nearby pen where the double-crested children were also confined. The rest suffered a blow of the mallet. The corpses were propped to face the wall of murk...

Above Ern's head sounded the mindless howl of a tinkle-bird. Ern darted back into the brush. The bird drifted overhead on clashing scales. Men ran to either side, chased Ern back and forth, and finally captured him. He was dragged to the village, thrust triumphantly up on the platform, amid calls of surprise and excitement. The four priests, or whatever their function, surrounded Ern to make their examination. There was a new set of startled outcries. The priests stood back in perplexity, then after a mumble of discussion signaled to the priest-women. The mallet was brought forward-but was never raised. A man from the crowd jumped up on the platform, to argue with the priests. They made a second careful study of Ern's head, muttering to each other. Then one brought a knife, another clamped Ern's head. The knife was drawn the length of his cranium, first to the left of the central ridge, then to the right, to produce a pair of near-parallel cuts. Orange blood trickled down Ern's face; pain made him tense and stiff. A woman brought forward a handful of some vile substance which she rubbed into the wounds. Then all stood away, murmuring and speculating. Ern glared back, half-mad with fear and pain.

He was led to a booth, thrust within. Bars were dropped across the aperture and laced with thongs.

Ern watched the remainder of the ceremony. The corpses were dismembered, boiled and eaten. The white-daubed girl-children were marshaled into a group with all those double-crested children with whom Ern had previously identified himself. Why, he wondered, had he not been included in this group? Why had he first been threatened with the mallet, then wounded with a knife? The situation was incomprehensible.

The girls and the two-crested children were marched away through the brush. The other girls with no more ado became members of the community. The male children underwent a much more formal instruction. Each man took one of the boys under his sponsorship, and subjected him to a rigorous discipline. There were lessons in deportment, knot-tying, weaponry, language, dancing, the various outcries.

Ern received minimal attention. He was fed irregularly, as occasion seemed to warrant The period of his confinement could not be defined, the changeless gray sky providing no chronometric reference; and indeed, the concept of time as a succession of definite interims was foreign to Ern's mind. He escaped apathy only by attending the instruction in adjoining booths, where single-crested boys were taught language and deportment Ern learned the language long before those under instruction; he and his double-crested fellows had used the rudiments of this language in the long-gone halcyon past.

The twin wounds along Ern's skull eventually healed, leaving parallel weals of scar-tissue. The black feathery combs of maturity were likewise sprouting, covering his entire scalp with down.

None of his erstwhile comrades paid him any heed. They had become indoctrinated in the habits of the village; the old life of the shallows had receded in their memories. Watching them stride past his prison, Ern found them increasingly apart from himself. They were lithe, slender, agile, like tall keen-featured lizards. He was heavier, with blunter features, a broader head; his skin was tougher and thicker, a darker gray. He was now almost as large as the men, though by no means so sinewy and quick: when need arose, they moved with mercurial rapidity.

Once or twice Ern, in a fury, attempted to break the bars of his booth, only to be prodded with a pole for his trouble, and he therefore desisted from this unprofitable exercise. He became fretful and bored. The booths to either side were now used only for copulation, an activity which Ern observed with dispassionate interest
