Jack and Molly clambered over the fence, and in doing so Jack lost one of his slippers, but did not miss it in his excitement, and they both ran a few steps along the path to get in sight of the Pumpkin again. [Illustration: JACK AND MOLLY CLAMBERED OVER THE FENCE] It was not so easy to see in the wood, for the trees met overhead and screened out the moonlight. Here and there a stray beam penetrated, scattering little pools of silver light on the ground; and each time the Pumpkin passed into these pools of light the children hastened their footsteps, but faltered again each time it glided into the gloom, where it was difficult to see and there was nothing save the crackling of the twigs to guide them. Suddenly Molly caught hold of her brother’s arm, and they both stood still. The Pumpkin had stopped in the dim light at the foot of a gigantic old tree with a gnarled and twisted trunk. Watching breathlessly, they saw it knock three times deliberately and heavily against the bark, and then roll back a few paces and wait. There was a low, creaking sound, and the side of the tree swung outward like a door; and the Pumpkin passed in. The door began slowly to close again. Jack and Molly looked at each other. What should they do? They both felt it was now or never. “Now!” said Jack. “Quick!” assented Molly. Like a flash they reached the door and slipped through—just in time. It closed behind them with a muffled thud, catching the sleeve of Jack’s coat as it did so, and they found themselves in complete darkness. Their curiosity and excitement turned to sudden fear when they heard the door close behind them, and they stood quite still, with their backs pressed hard against the interior of the 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.
