Then she shut her eyes tight, put her fingers in her ears, and leaped into the spring. She floundered around with her eyes still shut, and gasped and caught her breath just like a drowning person, until she heard the others laughing at her, and then she opened her eyes with astonishment.

Suddenly there was a loud, splashing sound heard above and around them and under their feet.

“Watch out!” cried Mr. Thimblefinger. “Run this way! The water is getting wet again!”

The way seemed to widen before them as they ran, and in a moment they found themselves below the “gum,” or “curb,” of the spring and beyond it. But as they went forward the bottom of the spring seemed to grow and expand, and the sun shining through gave a soft light that was very pleasant to the eye. The grass was green and the leaves of the trees and the flowers were pale pink and yellow.

Mr. Thimblefinger seemed to be very happy. He ran along before the children as nimbly as a killdee, talking and laughing all the time. Presently Drusilla, who brought up the rear, suddenly stopped in her tracks and looked around. Then she uttered an exclamation of fright. Sweetest Susan and Buster John paused to see what was the matter.

“Wharbouts did we come in at?” she asked.

Then, for the first time, the children saw that the bottom of the spring had seemed to expand, until it spread over their heads and around on all sides as the sky does in our country.

“Don’t bother about that,” said Mr. Thimblefinger. “No matter how big it looks, it’s nothing but the bottom of the spring after all.”

“But how are we to get out, please?” asked Sweetest Susan.

“The same way you came in,” said Mr. Thimblefinger.
