Albert sprang quickly up the ledge of rocks, and Sir Robert followed.

I saw Albert stoop, pick up a large fragment of rock, and hurl it--I saw Sir Robert fall, and then I grew sick and dizzy, and fainted.

I looked around, and there was Sir Robert, stretched out stiff and still and bloody.

He had worn nothing but a light cap on his head, and the stone had made a fearful dent in his temple.
