r an
animal trainer?"

"Oh, no," said Flossie, seriously. "Freddie means one of the tin bugs
that go around and around and around. And, if you please, I want a green
one."

"Say, I wonder what kind of children these are, anyhow," murmured the
guard. "Guess they must belong to a theatre or a circus."

"They look nice," said a man sitting near the door.

"Oh, they're all _right_, that's sure. Well, I'll see if I can find their
folks for 'em."

Elevated railroad men in New York get used to doing queer things, and
seeing strange sights, so it did not cause much excitement when the guard
went into the different cars calling for Mr. Bobbsey. He had to come back
to his own car once to call out "Forty-second Street," and to open the
gates to let passengers off and others on. Then he closed the gates and
called out: "Fiftieth Street next," After that he went again into the cars
he had not been in before and called for Mr. Bobbsey, But of course that
gentleman did not answer, being a station or two behind by this time.

The guard, not being able to find Mr. or Mrs. Bobbsey, or Nan and Bert,

"Did you find him?" asked the children eagerly.

"No, I'm sorry to say your father isn't on this train. But don't worry.
I'll look out for you, and your father is sure to come for you sooner or
later."

"Did you find any of the bugs?" asked Freddie.

"That go around and around and around," added Flossie.

"No," said the guard, laughing, "I didn't. What about them?"

Freddie explained what he meant, and asked if the train could not be
stopped while he went into the nearest toy store to buy some more of the
tin, crawling toys. But the guard said this could not be done.

"I don't just know what to do with you," he said, scratching his head. "If
your father thought, he could telephone to any of the stations where our
train will stop--this is an express train and does not make many stops
after Sixty-sixth Street till the end of the line. He could have the
agent there take you off and keep you until he could come. Or, I might
take you to One Hundred and Fifty-fifth Street, which is the end of the
line, and have the agent there take charge of you. I don't know what to
do."

Just then Flossie thought of something:

"Oh, Freddie!" she cried. "We haven't any tick
