“Winter’s come pretty early this year,” said Charlie Mason, one of Bert’s chums, as the two boys went down the hill together, bobsled fashion.

“Yes,” agreed Bert. “We’ll have a lot of fun at school to-morrow, making a snow fort. That is, if the snow doesn’t melt.”

But there was plenty of snow on the ground when the children awakened the next morning, though the storm had stopped and the sun was shining.

“I hope the sun doesn’t melt all the snow,” sighed Flossie, as she got ready to accompany her twin brother to school. They were in a lower class than Bert and Nan, but the smaller twins generally walked along with the older brother or sister.

It was when the Bobbsey twins were almost at school that John Marsh, a boy of about Bert’s age, came running around the corner of the street. John seemed rather out of breath and excited.

“What’s the matter?” asked Bert.

“Oh, that Danny Rugg and Sam Todd are pegging snowballs at me,” said John. “I wouldn’t mind soft ones, but they’re using hard balls. And they’re two to one—Sam and Danny both pegged at me.”

“That isn’t fair!” cried Bert. “They ought to fight square—even on both sides—and with soft balls. Come on, I’ll help you!”

Together the two lads went back and around the corner to the street where Danny and his rather mischievous crony were standing, leaving Nan to go with Flossie and Freddie on to school.

“Hi! There’s John again!” yelled Sam Todd, as he caught sight of the boy who had run away.
