She sat down on the root of an old tree that jutted out from an overhanging bank, and drew a sheet of paper from her pocket. She would write to her mother of their rescue of an airship. Mollie bit the end of her pencil—she was not in a writing mood. Why had she taken such a dislike to Reginald Latham? He had been polite enough, and was rather good-looking. It was Bab’s habit to feel prejudices, not hers. She wouldn’t say anything to her mother about him, but certainly Bab seemed to like him unusually well.

Crack! Crack! The sound came from the bushes! She looked quickly around. It must have been a gust of wind that stirred. In another minute there tumbled over her head a shower of leaves and acorns, that for an instant blinded her. But she could hear plainly this time; light feet were running along the bank above the ravine where she sat.

Without pausing a moment she jumped to her feet and ran up the path that led from the bottom of the ravine to the hilltop. Nothing was in sight; but further on through a thicket of trees, she caught the distant sound of flying footsteps. She could see the underbrush move, as though shaken by something in passing.

A shivering sense of mystery possessed the girl. Could it be the ghost?

Without stopping to think Mollie flew in pursuit; determined to discover what had disturbed her. Once she saw a bright object flash ahead of her, brown and scarlet, through the trees. It was gone in an instant. Surely it was but a shadow from the autumn leaves.

For some distance Mollie had been following what seemed to be a pathway through a tangled thicket of bushes and trees. Suddenly she stopped. So far as she could see the path ended abruptly. Yet, at this very moment, she heard a faint hallo!

It was the voice of temptation to Mollie, and she let her curiosity get the better of her. Without in the least knowing where she was going she pushed on. Ducking her head through an opening in one place, turning and twisting wherever she found it possible to make her way, the child came at last into a thick forest. On every side of her stretched endless avenues of trees. Now no sound of flying feet urged her on; no voice called her.

Poor Mollie was entirely alone.

“What an utter goose I am!” she declared out loud. “I don’t believe I ever heard anyone, or saw anything. It was just my imagination that led me on. Now, I hope,” Mollie gave a rueful smile and sat down to pull the brambles out of her dress, “I hope my imagination will kindly show me the way home again!”

Which way should she go? There were half a dozen different directions open to her. Which was the right one?
