"It's disappeared, as sure as shooting, Elmer," admitted the pilot of the ghost-hunting expedition; "but I give you my affidavy that I did see a face, a white one at that, though it flipped out of sight before I could grab a second look."

"Beats the Dutch what an imagination some fellows have got," grumbled George.

"I tell you I did see something, George!" repeated Toby, firmly.

"Sure, you might have done that," agreed the other, cheerfully; "but it's my honest opinion that it might have been just a little flash of sunlight on a window pane. I've known such a thing to startle me more'n once. And when you shifted your head, why, you got out of focus, and the thing disappeared as you say, like a wreath of smoke. Now, I'm one of the kind that likes to look deep into things; and I never let a mystery grip me. Make up your mind, Toby, that it was something like I'm telling you, and let it go at that."

Toby did not answer. Truth to tell he did not know what to say, for while he still firmly believed he had seen a human face at the window there was nothing around by means of which he could prove it.

He went to the window and looked out.

"Anyhow," he remarked, disconsolately, "even if I was fooled by something, it sure wasn't the sun, because it never strikes this side of the house after noontime; and look at the heavy trees shading it, will you? I give the thing up, and yet I'd like to take a look over this floor."

"Suppose we start in and do it, then?" remarked Elmer, quietly.

Even George accompanied them, though he continued to look superior, and allowed a skeptical expression to appear on his face. Possibly, in spite of his avowed disbelief in ghosts, George did not really care to be left alone in that house; his valor might all be on the surface.

Nothing was found, and Toby finally admitted that it seemed useless wasting any more time prowling around.
