The bob-sled was about half-way down the hill when Nan, sitting next to Tommy, who was behind Charley, gave a cry.
"Oh, look!" Nan exclaimed. "Flossie and Freddie! They're going to get right in our way! Steer out, Charley!"
The little Bobbseys, in taking their last coast, had come too near the part of the hill where the big sleds were.
"Flossie! Freddie!" cried Nan. "Look out! Steer away!"
But they did not seem able to do it.
"I guess we won't run into them," Charley said. He was trying as hard as he could to keep to one side.
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.
