“Oh, be careful!” cried Nan. “You’ll get your feet wet!”

“I have rubbers on,” said Bert.

There was nothing to do but to leave the bobsled and the other sleds in the shed attached to the garage. There they would stay until more snow came. When Bert went into the house, after putting away the bobsled and helping Flossie and Freddie store away their smaller sleds, he found his mother waiting for him.

“Bert,” said Mrs. Bobbsey, “here is a special delivery letter that just came for your father. It should have been delivered at the office, but they sent it here by mistake, and Dinah took it in before I could call to the boy to take it back with him. I called your father up about it on the telephone and he said, if you came in, to have you bring it down.”

“I’ll go,” replied Bert cheerfully.

“Oh, may we go along?” begged Flossie.

“We’ll be good!” promised Freddie.

“Shall I take them?” asked Bert of his mother.

“If you want to,” she answered. “Does Nan want to go?”

But Nan, as it happened, had some sewing she wanted to do on a Christmas gift for one of her girl friends, so she said she would stay in the house and busy herself with needle and thread. Thus it came about that Bert took the smaller Bobbsey twins down to his father’s office.
