that of a feather against the gigantic tension of the mass that any moment, it seemed, must lift him in its rising curve, bend, break, and twist him, then fling him crashing forward to his smothering fate.

Yet the moment never came. The Wave hung balanced between him and the sky, poised in mid-air. It did not fall. And the torture of that infinite pause contained the essence of the nightmare.

The Wave invariably came up behind him, stealthily, from what seemed interminable distance. He never met it. It overtook him from the rear. The horizon hid it till it rose.

There were stages in its history, moreover, and in the effect it produced upon his early mind. Usually he woke up the moment he realised it was there. For it invariably announced its presence. He heard no sound, but knew that it was coming—there was a feeling in the atmosphere not unlike the heavy brooding that precedes a thunderstorm, only so different from anything he had yet known in life that his heart sank into his boots. He looked up. There, above his head was the huge, curved monster, hanging in mid-air. The mood had justified itself. He called it the 'wavy feeling.' He was never wrong about it.

The second stage was reached when, instead of trying to escape shorewards, where there were tufts of coarse grass upon a sandy bank, he turned and faced the thing. He looked straight into the main under-body of the poised billow. He saw the opaque mass out of which this line rose up and curved. He stared against the dull, dun-coloured parent body whence it came—the sea. Terrified yet fascinated, he examined it in detail, as a man about to be executed might examine the grain of the wooden block close against his eyes. A little higher, some dozen feet above the level of his head, it became transparent; sunlight shot through the glassy curve. He saw what appeared to be streaks and bubbles and transverse lines of foam that yet did not shine quite as water shines. It moved suddenly; it curled a little towards the crest; it was about to topple over, to break—yet did not break.

About this time he noticed another thing: there was a curious faint sweetness in the air beneath the bend of it, a delicate and indescribable odour that was almost perfume. It was sweet; it choked him. He called it, in his boyish way, a whiff. The 'whiff' and the 'wavy feeling' impressed themselves so vividly upon his mind that if ever he met them in his ordinary life—out of dream, that is—he was sure that he would know them. In another sense he felt he knew them already. They were familiar.

But another stage went further than all the others put together. It amounted to a discovery. He was perhaps ten years old at this time, for he was still addressed as 'Tommy,' and it was not till the age of fifteen that his solid type of character made 'Tom' seem more appropriate. He had just told the dream to his mother for the hundredth time, and she, after listening with sympathy, had made her ever-green suggestion—'If you dream of water, Tommy, it means you're thirsty in your sleep,'—when he turned and stared straight into her eyes with such intentness that she gave an involuntary start.

'But, mother, it isn't water!'

'Well, darling, if it isn't water, what is it, then?' She asked the question quietly enough, but she felt, apparently, something of the queer dismay that her boy felt too. It seemed the mother-sense was touched. The instinct to protect her offspring stirred uneasily in her heart. She repeated the question, interested in the old, familiar dream for the first time since she heard it several years before: 'If it isn't water, Tommy, what is it? What can it be?' His eyes, his voice, his manner— something she could not properly name—had startled her.

But Tommy noticed her slight perturbation, and knowing that a boy of his age did not frighten his mother without reason, or even with it, turned his eyes aside and answered:

'I couldn't tell. There wasn't time. You see, I woke up then.'

'How curious, Tommy,' she rejoined. 'A wave is a wave, isn't it?'

And he answered thoughtfully: 'Yes, mother; but there are lots of things besides water, aren't there?'

She assented with a nod, and a searching look at him which he purposely avoided. The subject dropped; no more was said; yet somehow from that moment his mother knew that this idea of a wave, whether it was nightmare or only dream, had to do with her boy's life in a way that touched the protective thing in her, almost to the point of positive defence. She could not explain it; she did not like it; instinct warned her—that was all she knew. And Tommy said no more. The truth was, indeed, that he did not know himself of what the Wave was composed. He could not have told his mother even had he considered it permissible. He would have loved to speculate and talk about it with her, but, having divined her nervousness, he knew he must not feed it. No boy should do such a thing.

Moreover, the interest he felt in the Wave was of such a deep, enormous character—the adjectives were his own—that he could not talk about it lightly. Unless to some one who showed genuine interest, he could not even mention it. To his brothers and sister, both older and younger than himself, he never spoke of it at all. It had to do with something so fundamental in him that it was sacred. The realisation of it, moreover, came and went, and often remained buried for weeks together; months passed without a hint of it; the nightmare disappeared. Then, suddenly, the feeling would surge over him, perhaps just as he was getting into bed, or saying his prayers, or thinking of quite other things. In the middle of a discussion with his brother about their air-guns and the water-rat they hadn't hit—up would steal the 'wavy' feeling with its dim, familiar menace. It stole in across his brother's excited words about the size and speed of the rat; interest in sport entirely vanished; he stared at Tim, not hearing a word he said; he dived into bed; he had to be alone with the great mood of wonder and terror that was rising. The approach was unmistakable; he cuddled beneath the sheets, fighting-angry if Tim tried to win him back to the original interest. The dream was coming; and, sure enough, a little later in his sleep, it came.

For even at this stage of his development he recognised instinctively this special quality about it—that it could not, was not meant to be avoided. It was inevitable and right. It hurt, yet he must face it. It was as necessary to his well-being as having a tooth out. Nor did he ever seek to dodge it. His character was not the kind that flinched. The one thing he did ask was—to understand. Some day, he felt, this full understanding would come.

There arrived then a new and startling development in this curious obsession, the very night, Tommy claims, that there had been the fuss about the gun and water-rat, on the day before the conversation with his mother. His brother had plagued him to come out from beneath the sheets and go on with the discussion, and Tommy, furious at being disturbed in the 'wavy' mood he both loved and dreaded, had felt himself roused uncommonly. He silenced Tim easily enough with a smashing blow from a pillow, then, with a more determined effort than usual, buried himself to face the advent of the Wave. He fell asleep in the attempt, but the attempt bore fruit. He felt the great thing coming up behind him; he turned; he saw it with greater distinctness than ever before; almost he discovered of what it was composed.

That it was not water established itself finally in his mind; but more— he got very close to deciding its exact composition. He stared hard into the threatening mass of it; there was a certain transparency about the substance, yet this transparency was not clear enough for water: there were particles, and these particles went drifting by the thousand, by the million, through the mass of it. They rose and fell, they swept along, they were very minute indeed, they whirled. They glistened, shimmered,
