"You haven't entirely. You were chasing the same thing that I was,"
answered Tad thoughtfully.

"What's that? What's that you say?"

"I mean that somebody was here--somebody who had no business to be
here."

"You mean--"

"Yes, I mean that after I had been out here a few moments I distinctly
heard two men. One of them, it appears, was yourself. Who the other
was I don't know. He evidently got away. As I couldn't follow both
of them, I chose you. You seemed to be the easiest one to catch. I
was right, wasn't I?" laughed the boy, at the thought of the game they
had been playing with each other.

"Somebody else here? I knew it, I knew it," exclaimed the Professor.
"When I first came out you were sound asleep. I must have awakened
you when I fell over the saddle out there. Who left that thing there
for me to nearly break my neck on?" he demanded angrily.

"I guess it must be Chunky's saddle."

"Of course. I'll talk to him in the morning. I'm going to bed. I'll
catch my death of cold."
