They continued to whisper for some little time. Presently a dog set up a long, lugubrious howl just outside—within ten feet of them. The boys clasped each other suddenly, in an agony of fright.
"Which of us does he mean?" gasped Huckleberry.
"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.
