The thrill merged into a deep, huge sense of wonder that enthralled him. At the same moment the swallows, disturbed by his voice, looked up with one accord, then rose in a single sweep and whirled off into the upper air, wings faintly tinged with gold. They scattered. Tim watched them for a little while, dimly aware that he watched something "perfectly magnificent." His eyes followed one bird after another, caught in a sudden little rapture he could not understand… then turned and saw his bed, flushed with early pink, across the room. With a running jump he landed among the sheets, rolled himself up into a ball, and promptly fell asleep again. It was not yet four o'clock.

Across the landing, meanwhile, Judy, wakened by a brush of feathery wind, was at her window too. She felt very sure of something, although she didn't in the least know what. It was the same thing that Tim and Uncle Felix knew, only they knew they didn't know it, whereas she didn't know she knew it. Her knowledge, therefore, was greater than theirs.

The room was touched with soft grey light; it was to the west, and the night still clung about the furniture. Like a ball in a saucer, Maria lay asleep in bed against the opposite wall, her neutrality to all that was going on absolute as usual. But Judy did not wake her, she preferred to live alone; she knew that she was alive in her night-gown between night and morning, and that was an unusual pleasure she wished to enjoy without interference. For months she had not waked before half-past seven. The excitement of the unfamiliar was in her heart. She had caught the earth asleep—surprised it. For the first time in her life she saw "the Earth." She discovered it.

She knelt on a chair beside the open window, peering out, and as she did so, a strange, wild cry came sounding through the stillness. It was like a bugle-call, but she knew no human lips had made it. She glanced quickly in the direction whence it came—the pond—and the next instant the reeds about the edge parted and the thing that had emitted the curious wild cry emerged plainly into view. It was a pompous-looking creature. It came out waddling.

"It's the up-and-under bird," exclaimed Judy in a whisper. "Something's happening!"

It was a water-fowl, a creature whose mysterious habit of living upon the surface of the pond as well as underneath made the children's nick-name a necessity. And now it was attempting a raid on land as well. But land was not its natural place. Something certainly had happened, or was going to happen.

"It's a snopportunity," decided Judy instantly. Far more than an opportunity, a snopportunity was something to be snapped up quickly, the sort of thing that ordinarily happened behind one's back, usually discovered too late to be made use of. "I've caught it!" She remembered that the clocks had stopped, yet not knowing why she remembered it. It was the thing she didn't know she knew. She knew it before it happened. That was a snopportunity.

She watched the heavy bird for a considerable time as it slowly appropriated the land it had no right to. It moved, she thought, like a twisted drum on very short drumsticks. It had a water-logged appearance. It was bird and fish ordinarily, but now it was pretending to be animal as well—a thing that flew, swam, walked. Its webbed feet patted the ground complacently. It came laboriously towards the wall of the house, then halted. It paused a moment, then turned its eyes up, while Judy turned hers down. The pair of creatures looked at one another steadily for several seconds.

"You're not out for nothing," exclaimed Judy audibly. "So now I know!"

The reply was neither in the affirmative nor in the negative. The up-and-under bird said nothing. It made no sign. It just turned away, stalked heavily back across the lawn without once looking either to right or left, launched itself upon the water, uttered its queer bugle-call for the last and second time, and promptly disappeared below. The tilt of its vanishing tail expressed sublime indifference to everything on land. And Judy, reflecting vaguely that she, too, was something of an up-and-under creature, followed its example, though without the same dispatch or neatness of execution. She tumbled sideways into bed and disappeared beneath the sheets, aware that the bird had left her richer than it found her. It had communicated something that lay beyond all possible explanation. She had no tail, nor did she express indifference. On the contrary, she hugged herself, making sounds of pleasurable anticipation in her throat that lay plunged among depths of soothing pillows.
