blink so funny and come up and go out----"

"Just like winking at you," said Flossie. "I like it down here. It isn't
like the dark tunnels we went in on the steam cars."

"Well, I'm glad _somebody_ likes it," said Bert to Nan. "But say, how do
we get out of here?"

"I'm sure I don't know," she said. "When I ran after Flossie I didn't look
which way I was going."

"I didn't, either. Queer how we could get lost in a place like this," and
Bert seemed worried and spoke more loudly than he intended. Freddie heard
what his brother said and looked up quickly.

"Are we _really_ lost?" he asked.

"It seems so," answered Nan. "I ran after you two, and we have walked
about so many platforms and up and down so many stairs that I can't see or
remember the place where Father told us to wait for him."

"Well, there's no danger, that's sure," said Bert. "It's a queer place to
be lost in--a subway station. I was never in one before, but if we stay
here long enough Dad is sure to find us. Here comes somebody now, looking
for us, I guess."

A man in a blue suit, carrying a red lantern, and with white numbers on
either side of his cap, walked toward the four twins.

"Is your name Bobbsey?" he asked.
