“No,” I answered, “I don't hear him.”

“Where do you suppose he is? He could not have been far away when you met him.”

“He was not. And I know he intended to come back at once.”

“You don't suppose Caesar—the horse—ran away again? When that second crack came?”

I was wondering that very thing. That particular thunder clap was louder and more terrifying than those preceding it. However, there was no use in alarming her.

“I guess not,” I answered. “He'll be here soon, I am sure.”

But he did not come. The storm seemed to be passing over. The flashes were just as frequent, but there was a longer interval between each flash and its thunder peal. The rain was still a steady downpour.

Miss Colton was plainly growing more anxious.

“Where can he be?” she murmured.

“Don't be frightened,” I urged. “He is all right. I'll go and look him up, if you don't mind being left alone.”
