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,
came back to where Flossie and Freddie were now rather anxiously
waiting.

"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.
