"He'll be drowned! Don't you see, he is drowned? And suppose that bull comes back?"
"That bull won't get us down here, Nell," returned her brother, laying hold of the roots of the hollow tree and trying to turn it over.
But although he and Ruth both exerted themselves to the utmost, they could barely stir the stump. Suddenly they heard a struggle going on inside the hollow shell; as well, a thumping on the thin partition of wood and a muffled sound of shouting.
