Inside the cave Jem was leaning up against the wall, making strange noises and lifting up first one foot and then the other. He seemed to be suffering agonies, for he puffed and gasped.

“Jem, be quiet!” whispered Don, shaking him sharply.

“Oh, dear! Oh, dear!” groaned Jem, lifting up his bare feet alternately, and setting them down again with a loud pat on the rock.

“Be quiet! They may hear you.”

“Hit me then! Give it me. Ho, ho, ho!”

“Jem, we are safe now, and you’ll undo it all if you’re not quiet.”

“Knock me then, Mas’ Don. Oh, dear! Oh, dear! Hi: me; a good un, dear lad. Ho, ho, ho, ho!”

“Oh, do be quiet! How can you be such an ass?”

“I dunno! Oh, dear! Oh, dear! Did you see him run, Mas’ Don? I—oh dear, I can’t help it. Do knock me down and sit on me, dear lad—I never—oh dear me!”

Jem laughed till Don grew angry, and then the sturdy little fellow stopped short and stood wiping his eyes with the back of his hands.
