The young man was incredulous.

"You were near getting sunstruck when I picked you up," he laughed. "If you're going to Hunter's Island, why didn't you go to Pelham Manor?"

"That's right!" assented Jimmie eagerly. "But I wanted to save the ten cents so's to send Sadie to the movies. So I walked."

The young man looked his embarrassment.

"I beg your pardon," he murmured.

But Jimmie did not hear him. From the back of the car he was dragging excitedly at the hated suitcase.

"Stop!" he commanded. "I got ter get out. I got ter walk."

The young man showed his surprise.

"Walk!" he exclaimed. "What is it—a bet?"

Jimmie dropped the valise and followed it into the roadway. It took some time to explain to the young man. First, he had to be told about the Scout law and the one good turn a day, and that it must involve some personal sacrifice. And, as Jimmie pointed out, changing from a slow suburban train to a racing-car could not be listed as a sacrifice. He had not earned the money, Jirnmie argued; he had only avoided paying it to the railroad. If he did not walk he would be obtaining the gratitude of Sadie by a falsehood. Therefore, he must walk.
