tree-trunk, not daring to move. A soft, familiar rolling sound could be heard a short way in front of them. It ceased, there was a short silence, then came three distinct knocks, followed by a creaking noise, and another door opened on the other side of the tree. As the light crept into the interior of the tree the children saw to their astonishment that it was not moonlight, but daylight, the subdued light of evening.

A quick glance showed them the hollow interior of the huge tree and the distance they were from the open door. As they caught sight of the ground they both gave a start, for it was composed solely of half a dozen branches stretched across from side to side, and beneath the branches was a big black hole that went down and down and looked as if it had no bottom. They realized that they were standing at the extreme edge of the hole, on a little step of thick, sticky clay. However were they to walk over on one of those thin branches to the door on the other side without missing their footing and falling down into the hole? But even as they caught hold of hands, determined to make a desperate effort to cross while there was light to see, the Grey Pumpkin passed out into the daylight, and the door swung slowly to again, and they were left in darkness once more.

They stood stock still, not daring to move.

“Oh, Jack, whatever shall we do?” said Molly, almost crying.

“Knock on the door behind us and go back home,” suggested Jack. “Let’s get out of this old dark hole, and the Pumpkin can go where it jolly well likes.... Leave go my arm a moment, Molly, and I’ll turn round and knock.” He turned to suit the action to his words, tearing the corner of his sleeve out of the crack as he did so.

“But, Jack,” Molly said hurriedly. “Wait a minute.... Somehow ... I’ve got a feeling that we ought to go on, if only we could.... Don’t knock yet, Jack.... I feel as if somebody wants us, through that door on the other side ... if only we could get across. Oh, Jack, do be careful—you’ll slip!”

“Look here,” said Jack, “are you afraid to chance the crossing—do you really think it’s worth it?”

“The Pumpkin must have rolled across without the floor giving way—but then, it—he—I mean, what shall we do, Jack?”

“Shall we try?” suggested Jack.

Molly hesitated. Then “Yes, let’s,” she said. “Only—shall we?” she faltered.

“You stay here while I go across and knock three times on the other door,” said Jack, at once decided. “Then while it’s light you run across.”

“Oh, Jack, do be careful,” cried Molly.

For Jack had already started. He felt with his foot for the thickest branch and stepped recklessly forward. To his delight he found that it was quite easy to walk across, and all their fears had been groundless.

“Why, Moll,” he called joyfully, “it’s as easy as anything. Wait a sec. I’m almost there.”

He reached the clay step on the other side and gave three good knocks to relieve his feelings. With a low creaking the door opened slowly, and as the light streamed in Molly ran quickly and easily across, and the next moment they both stood outside the tree, and the door was shut.

CHAPTER III
The Other Side of the Tree

The two children gazed in astonishment at the unfamiliar scene in front of them, for here was a place they had never seen before, and yet, apparently, a place within ten minutes’ walk of their home—a place that led out of the little wood at the end of their garden. And they thought they knew every nook and corner of that wood, and of the fields and lanes beyond for several miles round their house. Yet here was a place they had never seen before; and, more puzzling still, the soft glow of evening and sunset had taken the place of the moonlight and gloom which had been all around them in the wood. For they were still standing close to the same big old tree, but instead of the wood continuing for a quarter of a mile on, and ending at the edge of Farmer Hart’s cornfields as it always had done, it ended abruptly right in front of them, by the side of a broad white road. This road stretched away to the left, up and up a big hill. You could see it winding like a white ribbon, bordered by the green and brown trees of the woods that clustered on each side. And, at the top of the hill, where the road ended, glistened the white walls and roofs of a distant city. To the right the road continued past the wood where the children were standing, and sloped down, down, till it was lost to sight in the burning crimson and gold afterglow of the sunset.

Jack and Molly looked up the road and down the road, but all was silent, and not a soul in sight. Then a wisp of blue smoke among the trees on the opposite side of the road caught their attention, and they saw that it was curling from the chimney of a snug little red-roofed cottage, which nestled, half hidden, on the fringe of the wood across the road.

The children looked at each other in bewilderment. Then they turned and examined the giant tree behind them, but that did not help them much. It was certainly the same tree, but it was not the same wood. Something queer had happened—it did not seem to be even the same country. They looked up and down the road again, and behind them and before them—and listened. But all was silent. Their eyes wandered back to the curling blue smoke, the only sign of life within sight.

“Better ask some one where we’ve got to,” said Jack, eyeing the smoke.

“But where’s IT gone?” began Molly, then broke off quickly. “Hush! What’s that!” she said.

She plucked Jack’s sleeve and drew him into the shadow of the trees. A distant sound of voices came floating through the still evening air. There were evidently two speakers, for, as the sounds drew nearer the children could hear a high, loud, jolly voice, flowing continuously, and punctuated every now and then by a low, mumbling voice. After a few seconds the words of the high-voiced speaker became distinguishable.

“Stuff and nonsense!” it cried shrilly. “Pull yourself together, Father. Come now, come now, snap your fingers in its face! Laugh at it, I say, and—tss——” The speaker made a little hissing noise. “Where is it?”

The other voice here murmured some reply too low for the children to catch.

“What’s that?” replied the first speaker. “No—not you. But I’ll tell you what will happen, you’ll be having an attack of melancholia——”

“Oh, not that, not that!” The low voice was raised and pleading. “Don’t talk of melons, Glan, don’t, I pray you. They make me think of those lemons—and the—and——”

“Now don’t you think of that any more,” ordered the high voice. “Come, come, come. Pull yourself together....”

The speakers became visible, wending their way through the wood in which the children were standing. One was a young, fat, rosy-cheeked man, with a jolly smile, wearing a white overall and white baker’s cap; he was clean-shaven, and was the possessor of the high voice. His companion was a striking contrast to him, being old and thin and pale, with a long white beard; he was dressed in a rich, dark-coloured robe, and had a number of keys dangling from his belt. They pulled up short when they caught sight of Jack and Molly; then advanced slowly, with sidelong glances at each
