Now they were right away from the marsh and the sands, and would not see them until they returned, although from the moor and fell-land surrounding Witham it was always possible to see the bay. Indeed, in this part of the little county it was hard to get away from the knowledge of the sea, and even further in, among the shouldering peaks, you had only to climb awhile to find the water almost within a throw. On days like this, however, even on the beach it was hard to tell which was water and which mist, and when at last the tide drew silently from beneath, those who looked at it from the hills could not tell whether it went or stayed.

Simon, looking drearily around, thought that the whole earth had a drowned appearance to-day. It reminded him of the marsh after it had been swamped by a flood, and the miserable land emerged soddenly as the sea drew back. Everything was so still, too, with the stillness of the dead or drugged. Only the mist moved steadily and of set purpose, though it was the purpose of a creature with shut eyes walking in its sleep.

Out of the low vapour softly roofing the fields a gull came flying slowly over their heads. First Simon saw the shadow of it huge upon the mist, and then it came swooping and circling until it hung above the road. Its long, pointed wings and drooping legs were magnified by the distorting air, and presently he could see the colour of its bill and the gleam of its expressionless eye. It moved in that lifeless atmosphere as a ship that has lost the wind moves still by its gathered momentum over a deadened sea, but when it came over the road it turned to follow the trap, instead of making away at an angle towards the west. Simon concluded that it must have lost its way in the mist, and was following them as sea-birds follow a boat, but presently he was reminded of the car in this leisurely gliding on their track. Like the car, too, it drew level at last, but this time he was not afraid. He looked up at it, indeed, but without much interest, watching its lone vagrancy with apathetic eyes. It was silent at first as it circled and swooped, looping its aimless, unnecessary curves, yet always travelling on. It might have been a piece of the wandering mist that had taken shape, yet the sluggish, unbuoyant atmosphere seemed scarcely to have sufficient strength to carry its weight. So low it flew at last that it almost brushed their faces and the horse's ears, and in fancy he felt the touch of it damp and soft against his cheek. And then, as it dropped for the hundredth time, it suddenly spoke.

Sarah started violently when the cry broke over her head, the harsh wailing cry that makes all sands desolate and all moorland lone. She lifted her face to search the curtained sky as well as she could, but already the bird had left them and mounted higher, as if called and turned to another road. Each cry as it came was fainter than the last, like the speech of a passing soul ever further off. There was about it something of the majesty and terror of all irrevocable retreats, of those who go forth unhesitatingly when summoned, never to return. It left behind it the same impulse to reach out passionate, yearning arms, to cry aloud for the fainting answer that would still go on long after the ear had ceased to take it in.

Sarah sat with her face lifted to the last, trembling and drawing short, uneven breaths. Simon was silent until she had settled again, and then--"It was nobbut a gull," he said, at length.

She gave a deep sigh, and folded her hands tightly before her in their black cotton gloves.

"We've plenty on 'em, I'm sure, down on t'marsh.... I'm that used to them, I never hear their noise."

She turned her head slightly towards him, as if in a vain attempt to see his face.

"Ay, but it was that like," she answered in a suppressed tone. "Eh, man, but it was terble like!"

He gave a grunt by way of reply, knowing well enough what she meant, but knowing also that there was nothing to say. It was not true, of course, that he never heard the gulls. He heard them always, and behind them the voice that called across the years. But they had long since ceased to talk about it or to take the voice of the present for the voice of the past. Sometimes, indeed, when the cry came at the window on a stormy night, they started and looked at each other, and then looked away. But it was not often that they were deceived, as Sarah had been to-day. Even now, he felt sure, she was straining after the voice, that would never cease crying until it reached the tide.
