“Well, if you’re quite through,” snapped Ned, “maybe you’ll call it a day. We’ve got things to do.”

“Meaning you’d like me to beat it?” asked the visitor, good-temperedly.

“Sure,” agreed Proudtree, eagerly, “that’s what I meant. But say, I didn’t mean to hurt any one’s feelings. Geewhillikins, if I got waxy every time the fellows josh me about being fat—” Words failed him and he sighed deeply.

Laurie laughed. “We might start a side-show, the three of us, and make a bit of money. ‘Only ten cents! One dime! This way to the Siamese Twins and the Fat Boy! Walk up! Walk up!’”

Proudtree smiled wanly. “I only weigh a hundred and seventy-eight and three quarters, too,” he said dolorously. “If I was a couple of inches taller it wouldn’t be so bad.”
