She was trembling all over with her rage, and he mistook it for weeping.

"I didn't mean to make you cry, Miss Worthington," he began.

Her angry dark eyes flashed around at him for a moment. "I'm not crying!" she announced with emphasis, and then turned away from him again.

But that one brief glance had shown him how far she was from tears. "Well, I most certainly didn't mean to make you mad," he had only to change the words of his apology. "But ... that was funny!"

"Why?" she demanded, peremptorily, half turning back to face him.

"It just was! You ask your father!" Arethusa's expression remained most unrelenting. "But I really do beg your pardon, in all humbleness, for laughing at you. It was horribly rude of me, I'll have to admit, and I'm certainly sorry that I did it. So do forgive me this time, and let's go on being friends. Please...." he coaxed.

Arethusa softened, just the least bit. "But why was it so funny, what I said? You didn't tell me. Oughtn't I to have said it?"

"It wasn't what you said. There wasn't anything so dead wrong in that. You could talk about such creatures all you wanted, I suppose, and still not commit anything that wasn't right according to Hoyle. It was the way you handed it out that got my goat so completely!" He gurgled reminiscently. "But listen here, Miss Arethusa, you do just what I'm telling you and you let the natural history alone for the rest of this party, no matter what your book said about it. You can the high-brow stuff from now on, and you'll get along better."

She could plainly tell that every word of this was meant as advice between friends. It was impossible to construe Mr. Watts' manner as anything but eagerness to help. And it sounded delightfully like Timothy in their happier moments.

Her face broke into a forgiving smile.
