"You play altogether too hard. Take it easy. The snow will last a long time," went on Mr. Bobbsey.
After lunch Bert did not dare to go back to school. But he could think of no excuse for staying home and at last set off in company with Nan. He looked around for Danny, but the big lad did not show himself.
"What's the matter with you, Bert?" questioned his twin sister, as they trudged along.
"Nothing is the matter, Nan."
"But there is. You act so strange."
"I—I don't feel very good."
"Then you did run too hard, after all."
"It wasn't that, Nan." Bert looked around him. "Do you see anything of Danny Rugg?"
"No." Nan stopped short. "Bert Bobbsey, did you have a fight with him?"
"No—that is, not a real fight. I chased him with some snowballs and he threw a big chunk of ice at me."
