close to their father's lumber dock, calling their thanks to Mr. Watson.

"I'll take you again, some time," he answered, as he sailed off down the
lake.

"Ah, ha! And so my little fat fireman had a ride in an ice-boat, did he?"
cried Mr. Bobbsey that night, when he came home from the office and heard
the story. "And how did my little fat fairy like it?" And he lifted up
first Freddie and then Flossie to kiss them. "Fat fireman" and "fat fairy"
were Mr. Bobbsey's pet names for the smaller twins. Bert and Nan had had
pet names when they were small, but they were too large for them now,
growing out of them as they grew out of their clothes.

"Oh, it was glorious!" cried Nan. "Sailing in an ice-boat must be like the
way it feels to be in an airship."

"I'm going up in an airship when I get big!" cried Freddie, making a dive
after Snoop, the cat, who was hiding under the table.

"Have you heard yet whether you are to go?" asked Mrs. Bobbsey, of her
husband, when the noisy greetings to the children were over.

"No, not yet," he answered, and he made a motion with his head, as if to
tell his wife not to speak of a certain matter before the children.

"Oh, I saw you wink!" cried Nan, clapping her hands. "What does it mean?
Is it a secret, Momsey?"

"Well, yes, Nan. You shall be told in plenty of time, if anything comes of
it."
