“Did we pass this big fountain?” he questioned abruptly.

“I—don’t remember it,” Polly faltered.

“We’re on the wrong path,” he hastily concluded. “Let’s go back!”

They wheeled about, and were soon following a driveway that they were sure led to the park entrance. Yet they trudged on and on, and still the green expanse, dotted with trees, flower-beds, and shrubbery seemed to stretch endlessly before them.

“Seems ’s if we ought to get somewhere pretty soon,” observed Polly, a plaintive note in her voice.

David replied absently. He was thinking hard. Where was that big stone gateway? He strained his eyes in a vain endeavor to discern it in the distance.
