All at once the bob-sled struck a lump of ice, and the front sled jumped into the air. Charley Mason was jarred so hard that he rolled off. The bob-sled swayed from side to side when no one was steering it.
Then Flossie and Freddie, on their sleds, steered right over in the way of the bob-sled. They could not help it, they said afterward, and that was probably true, for they did not know much about steering sleds.
"Oh!" cried Nan. "We'll run right over them."
But Tommy Todd, who was sitting behind Charley, slid forward as the other boy rolled off, and now Tommy grasped the steering wheel with all his might.
He twisted it around, to send the bob-sled away from Flossie and Freddie, who were almost under the runners now. Bert, who saw what was about to happen, was ringing the bell as hard as he could. The other boys were yelling and the girls were screaming.
"Flossie! Freddie! Fall off your sleds! Roll out of the way!" yelled Nan.
