Meantime the giant continued to raise his iron mallet high in the air and to strike the path terrific blows that echoed through the mountains like the roar of a cannon. Each time the mallet lifted, however, there was a moment when the path beneath the monster was free, and perhaps the Scarecrow had noticed this, for when he came back to the others he said: "The matter is a very simple one, after all. We have but to run under the hammer, one at a time, when it is lifted, and pass to the other side before it falls again." "It will require quick work, if we escape the blow," said the Tin Woodman, with a shake of his head. "But it really seems the only thing to be done. Who will make the first attempt?" They looked at one another hesitatingly for a moment. Then the Cowardly Lion, who was trembling like a leaf in the wind, said to them: "I suppose the head of the procession must go first--and that's me. But I'm terribly afraid of the big hammer!" "What will become of me?" asked Ozma. "You might rush under the hammer yourself, but the chariot would surely be crushed." "We must leave the chariot," said the Scarecrow. "But you two girls can ride upon the backs of the Lion and the Tiger." So this was decided upon, and Ozma, as soon as the Lion was unfastened from the chariot, at once mounted the beast's back and said she was ready. "Cling fast to his mane," advised Dorothy. "I used to ride him myself, and that's the way I held on." So Ozma clung fast to the mane, and the lion crouched in the path and eyed the swinging mallet carefully until he knew just the instant it would begin to rise in the air. Then, before anyone thought he was ready, he made a sudden leap straight between the iron giant's legs, and before the mallet struck the ground again the Lion and Ozma were safe on the other side. The Tiger went next. Dorothy sat upon his back and locked her arms around his striped neck, for he had no mane to cling to. He made the leap straight and true as an arrow from a bow, and ere Dorothy realized it she was out of danger and standing by Ozma's side. Now came the Scarecrow on the Sawhorse, and while they made the dash in safety they were within a hair's breadth of being caught by the descending hammer.
