While the sun and the rain live, these shall be;
Till a last wind's breath upon all these blowing
Roll the sea.

THE ISLAND LAY IN
shadows only a little deeper than those that were swiftly stealing across the sound from the east. On its western shore the wet sand of the narrow beach caught the same reflection of palely gleaming sky that laid a bright path across the water from island beach to horizon. Both water and sand were the color of steel overlaid with the sheen of silver, so that it was hard to say where water ended and land began.
Although it was a small island, so small that a gull might have flown across it with a score of wing beats, night had already come to its northern and eastern end. Here the marsh grasses waded boldly out into dark water, and shadows lay thick among the low-growing cedars and yaupons.
With the dusk a strange bird came to the island from its nesting grounds on the outer banks. Its wings were pure black, and from tip to tip their spread was more than the length of a man's arm. It flew steadily and without haste across the sound, its progress as measured and as meaningful as that of the shadows which little by little were dulling the bright water path. The bird was called Rynchops, the black skimmer.
As he neared the shore of the island the skimmer drifted closer to the water, bringing his dark form into strong silhouette against the gray sheet, like the shadow of a great bird that passed unseen above. Yet so quietly did he approach that the sound of his wings, if sound there were, was lost in the whisper song of the water turning over the shells on the wet sand.
At the last spring tide, when the thin shell of the new moon brought the water lapping among the sea oats that fringed the dunes of the banks, Rynchops and his kin had arrived on the outer barrier strip of sand between sound and sea. They had journeyed northward from the coast of Yucatan where they had wintered. Under the warm June sun they would lay their eggs and hatch their buff-colored chicks on the sandy islands of the sound and on the outer beaches. But at first they were weary after the long flight and they rested by day on sand bars when the tide was out or roamed over the sound and its bordering marshes by night.
Before the moon had come to the full, Rynchops had remembered the island. It lay across a quiet sound from which the banks shouldered away the South Atlantic rollers. To the north the island was separated from the mainland by a deep gutter where the ebbing tides raced strongly. On the south side the beach sloped gently, so that at slack water the fishermen could wade out half a mile before the water came above their armpits as they raked scallops or hauled their long seines. In these shallows young fishes swarmed, feeding on the small game of the waters, and shrimp swam with backward flipping of their tails. The rich life of the shallows brought the skimmers nightly from their nesting grounds on the banks, to take their food from the water as they moved with winnowing flight above it.
About sunset the tide had been out. Now it was rising, covering the afternoon resting places of the skimmers, moving through the inlet, and flowing up into the marshes. Through most of the night the skimmers would feed, gliding on slender wings above the water in search of the small fishes that had moved in with the tide to the shelter of grassy shallows. Because they fed on the rising tide, the skimmers were called flood gulls.
On the south beach of the island, where water no deeper than a man's hand ran over gently ribbed bottom, Rynchops began to wheel and quarter over the shallows. He flew with a curious, lilting motion, lifting his wings high after the downstroke. His head was bent sharply so that the long lower bill, shaped like a scissor blade, might cut the water.
The blade or cutwater plowed a miniature furrow over the placid sheet of the sound, setting up wavelets of its own and sending vibrations thudding down through the water to rebound from the sandy bottom. The wave messages were received by the blennies and killifish that were roving the shallows on the alert for food. In the fish world many things are told by sound waves. Sometimes the vibrations tell of food animals like small shrimps or oar-footed crustaceans moving in swarms overhead. And so at the passing of the skimmer the small fishes came nosing at the surface, curious and hungry. Rynchops, wheeling about, returned along the way he had come and snapped up three of the fishes by the rapid opening and closing of his short upper bill.
Ah-h-h-h,
called the black skimmer.
Ha-a-a-a! Ha-a-a-a! Ha-a-a-a!
His voice was harsh and barking. It carried far across the water, and from the marshes there came back, like echoes, the answering cries of other skimmers.
While the water was reclaiming inch after inch of sandy shore, Rynchops moved back and forth over the south beach of the island, luring the fishes to rise along his path and seizing them on his return. After he had taken enough minnows to appease his hunger he wheeled up from the water with half a dozen flapping wing beats and circled the island. As he soared above the marshy eastern end schools of killifish moved beneath him through the forests of sea hay, but they were safe from the skimmer, whose wingspread was too great to allow him to fly among the clumps of grass.
Rynchops swerved out around the dock that had been built by the fisherman who lived on the island, crossed the gutter, and swept far over the salt marshes, taking joy in flight and soaring motion. There he joined a flock of other skimmers and together they moved over the marshes in long lines and columns, sometimes appearing as dark shadows on the night sky; sometimes as spectral birds when, wheeling swallow-like in air, they showed white breasts and gleaming underparts. As they flew they raised their voices in the weird night chorus of the skimmers, a strange medley of notes high-pitched and low, now soft as the cooing of a mourning dove, and again harsh as the cawing of a crow; the whole chorus rising and falling, swelling and throbbing, dying away in the still air like the far-off baying of a pack of hounds.
The flood gulls circled the island and crossed and recrossed the flats to the southward. All through the hours of the rising tide, they would hunt in flocks over the quiet waters of the sound. The skimmers loved nights of darkness and tonight thick clouds lay between the water and the moon's light.
On the beach the water was moving with soft tinkling sounds among the windrows of jingle shells and young scallop shells. It ran swiftly under heaps of sea lettuce to rouse sand fleas that had taken refuge there when the tide ebbed that afternoon. The beach hoppers floated out on the backlash of each wavelet and moved in the returning water, swimming on their backs, legs uppermost. In the water they were comparatively safe from their enemies the ghost crabs, who roamed the night beaches on swift and silent feet.
In the waters bordering the island many creatures besides the skimmers were abroad that night, foraging in the shallows. As the darkness grew and the incoming tide lapped higher and higher among the marsh grasses, two diamondback terrapins slipped into the water to join the moving forms of others of their kind. These were females, who had just finished laying their eggs above the high-tide line. They had dug nests in the soft sand, working with hind feet until they scooped out jug-shaped holes not quite so deep as their own bodies were long. Then they had deposited their eggs, one five, the other eight. These they had carefully covered with sand, crawling back and forth to conceal the location of the nest. There were other nests in the sand, but none more than two weeks old, for May is the beginning of the nesting season among the diamondbacks.
As Rynchops followed the killifish in toward the shelter of the marsh he saw the terrapins swimming in the shallow water where the tide was moving swiftly. The terrapins nibbled at the marsh grasses and picked off small coiled snails that had crept up the flat blades. Sometimes they swam down to take crabs off the bottom. One of the two terrapins passed between two slender uprights like stakes thrust into the sand. They were the legs of the solitary great blue heron who flew every night from his rookery three miles away to fish from the island.
The heron stood motionless, his neck curved back on his shoulders, his bill poised to spear fish as they darted past his legs. As the terrapin moved out into deeper water she startled a young mullet and sent it racing toward the beach in confusion and panic. The sharp-eyed heron saw the movement and with a quick dart seized the fish crosswise in his bill. He tossed it into the air, caught it head first, and swallowed it. It was the first fish other than small fry that he had caught that night.
The tide was almost halfway to the confused litter of sea wrack, bits of sticks, dried claws of crabs, and broken shell fragments that marked high-water level. Above the tide line there were faint stirrings in the sand where the terrapins had lately begun to lay their eggs. The season's young would not hatch until August, but many young of the year before still were buried in the sand, not yet roused from the torpor of hibernation. During the winter the young terrapins had lived on the remnant of yolk left from embryonic life. Many had died, for the winter had been long and the frosts had bitten deep into the sands. Those that survived were weak and emaciated, their bodies so shrunken within the shells that they were smaller than when they had hatched. Now they were moving feebly in the sands where the old terrapins were laying the eggs of a new generation of young.
About the time the tide was midway to the flood, a wave of motion stroked the tops of the grasses above the terrapin egg bed, as though a breeze passed, but there was little wind that night. The grasses above the sand bed parted. A rat, crafty with the cunning of years and filled with the lust for blood, had come down to the water along a path which his feet and his thick tail had worn to a smooth track through the grass. The rat lived with his mate and others of his kind under an old shed where the fisherman kept his nets, faring well on the eggs of the many birds that nested on the island, and on the young birds.
As the rat looked out from the fringe of grass bordering the terrapin nests the heron sprang from the water a stone's throw away with a strong flapping of his wings and flew across the island to the north shore. He had seen two fishermen in a small boat coming around the western tip of the island. The fishermen had been gigging flounders, spearing them on the bottom in shallow water by the light of a torch which flared at the bow. A yellow splotch of light moved over the dark water in advance of the boat and sent trembling streamers across the wavelets that rippled shoreward from the boat's passing. Twin points of green fire glowed in the grass above the sand bed. They remained stationary until the boat had passed on around the south shore and had headed toward the town docks. Only then did the rat glide down from the path onto the sand.
The scent of terrapin and of terrapin eggs, fresh laid, was heavy in the air. Snuffling and squeaking in excitement, the rat began to dig and in a few minutes had uncovered an egg, had pierced the shell, and sucked out the yolk. He then uncovered two other eggs and might have eaten them if he had not heard a movement in a near-by clump of marsh grassâthe scrambling of a young terrapin struggling to escape the water that was seeping up around its tussock of tangled roots and mud. A dark form moved across the sand and through the rivulet of water. The rat seized the baby terrapin and carried it in his teeth through the marsh grasses to a hummock of higher ground. Engrossed in gnawing away the thin shell of the terrapin, he did not notice how the tide was creeping up about him and running deeper around the hummock. It was thus that the blue heron, wading back around the shore of the island, came upon the rat and speared him.
