"I dono--peep through the crack. Quick!"

     "No, you, Tom!"

     "I can't--I can't do it, Huck!"

     "Please, Tom. There 'tis again!"

     "Oh, lordy, I'm thankful!" whispered Tom. "I know his voice. It's Bull Harbison." *

     [* If Mr. Harbison owned a slave named Bull, Tom would have spoken of him as "Harbison's Bull," but a son or a dog of that name was "Bull Harbison."]

     "Oh, that's good--I tell you, Tom, I was most scared to death; I'd a bet anything it was a stray dog."

     The dog howled again. The boys' hearts sank once more.

     "Oh, my! that ain't no Bull Harbison!" whispered Huckleberry. "Do, Tom!"

     Tom, quaking with fear, yielded, and put his eye to the crack. His whisper was hardly audible when he said:

     "Oh, Huck, its a stray dog!"

     "Quick, Tom, quick! Who does he mean?"
