“ They were little, withered old men, with legs like drum-sticks, and arms longer and thinner than their legs. They kept nodding their great ugly heads, squinting their horrid eyes, wriggling their hooked noses, and grinning from ear to ear.Tom lay there trembling and frightened almost to death. Then the oldest and ugliest of the Knockers came close to him, and stooping, made the most horrid grimaces in Tom’s face; while all the others lolled out their tongues, and rolled themselves into balls, and grinned at him from between their spindle-legs. ”
