d. For one thing, it
kept him wide awake, and for another, his father always gave every
woman his seat in a crowded car, and Sunny Boy was sure he would be
glad to hear that Sunny Boy had done the same.

"And what do we do to-morrow?" this same Daddy asked that night as he
helped a very tired, sleepy little boy to get ready for bed. "I'm
going to play with you and Mother all day, you know."

Sunny Boy was ready with his reply.

"To-morrow," he said indistinctly, in the midst of a big yawn, "we're
going to travel quick on the subway!"

CHAPTER XI

SUNNY BOY GETS LOST

"Do you remember when you were counting up the kinds of cars you had
ridden on?" asked Daddy, as he and Sunny Boy stood on the walk waiting
for Mother, who had gone into a drugstore to buy some postage stamps.

Sunny Boy nodded.

"Well, the subway is one kind you haven't been on," said Daddy.

Sunny Boy was surprised.

"But it isn't cars, Daddy," he argued. "I think it is a boat."

bright in the subway station, and Sunny Boy thought that it did not
seem like a cellar at all.

He stood as close to the edge of the platform as his father would let
him and peered up the track. It was dark, like a tunnel, and colored
lights winked at him from the walls.

"Will the next be our train?" he asked.

"We can take any that comes," answered Daddy. "This is an express
station. See the red light coming--that is a train."

A tiny red glow far in the distance grew larger and larger, and the
roar and rumble of the train was heard. A long train of cars,
brilliantly lighted, swept past them, such a long train that Sunny Boy
thought at first that it was not going to stop. But it did.

"Where's the engine?" he asked disappointedly, as he and Mother and
Daddy stepped on through a center door.

"There isn't any engine," repl
