“Are you sure?” asked the Bobbsey girl.

“Cou’se I is!” replied Sam. “Where could dey be losted at?”

“They might have gone away over the fields to roll a big snowball, or something like that,” suggested Nan. “And then they might have wandered to the woods and now can’t find their way back.”

“No, I don’t believe dat,” said Sam. “You say dey came out to play in de garage?”

“That’s what Mrs. Pry says,” answered Nan. “Freddie came in to get some of her cookies, and when she asked him what he was going to do he said he and Flossie were going to play in the garage.”

Sam shook his head.

“I been out here ’most all de afternoon,” he said. “I didn’t see Flossie or Freddie. Cou’se dey might hab slipped in when I went to de house to git a bucket of hot watah. I’ll take a look around to make suah!”

He opened the garage again and turned on the electric lights, for it was so equipped. Then Nan and Sam looked all over the first floor without finding a sign of the children.

“What’s the matter?” asked Bert, hurrying out to the garage, having heard from Mrs. Pry and Dinah that Nan had gone to bring in the smaller twins.

“Oh, Flossie and Freddie are lost!” half sobbed Nan.
