He raised his hand, and spoke slowly in a clear cold voice. ‘Saruman, your staff is broken.’ There was a crack, and the staff split asunder in Saruman’s hand, and the head of it fell down at Gandalf’s feet. ‘Go!’ said Gandalf. With a cry Saruman fell back and crawled away. At that moment a heavy shining thing came hurtling down from above. It glanced off the iron rail, even as Saruman left it, and passing close to Gandalf’s head, it smote the stair on which he stood. The rail rang and snapped. The stair cracked and splintered in glittering sparks. But the ball was unharmed: it rolled on down the steps, a globe of crystal, dark, but glowing with a heart of fire. As it bounded away towards a pool Pippin ran after it and picked it up.
