ied his father. "Don't you remember the
elevated train has no engine, either? Both kinds of trains are run by
electricity. If Mother doesn't mind, we'll go up in the first car and
watch from the front door."

Mrs. Horton didn't mind, even though they had to walk almost the
length of the train to reach the first car. There were plenty of
seats in this car, and Mrs. Horton sat down to rest while Sunny Boy
and his father stood at the door and peered through the glass panel.
They could see the tracks stretching ahead of them, and as they
watched the train flashed through a station without stopping.

Sunny Boy was delighted.

"Let's ride all day," he suggested. "Don't get off, Daddy. See the
blue light! What's that for?"

Mr. Horton didn't know. It was some sort of signal for the engineer.
The engineer was shut away from them in a little enclosed corner space
where it was dark and he could see the lights ahead of him plainly.

When they stopped at a station, many people always got off, but
seemingly as many crowded on.

"Where are we going, Daddy?" Sunny Boy thought to ask at one of these
stops.

"A long way," Daddy assured him. "Up to Bronx Park and the Zoological
Garden. I thought you'd like to see the animals."

Sunny Boy was fond of animals, but he was sure that he would never
again have as much fun as he was having watching the train speed along
those dark shining rails.

"You can go and sit down, if you're tired, Daddy," he told his father.
"I can stay here alone."

Mr. Horton did go back and sit down beside Mother.

"I guess maybe I will sit down a minute," said Sunny Boy, after he had
stood up for many blocks. "I'm not tired, but my feet are."

Then, before his feet were rested, Daddy announced that the next
station was theirs. They were out of the subway now, riding along in
the open air, and he took Mother's hand.

"And now," said Mr. Horton, with a smile for Sunny as they left the
train and, after a short walk, entered the park, "let's see
everything!"

This they proceeded to do.

There isn't room to tell you of the wonderful animals they saw, the
buffaloes, the beautiful deer, so tame that they came up to the wires
to have their noses rubbed; of the lions and tigers and panthers and
leopards; of strange animals that Sunny Boy had never seen even in his
book of wild animals; and of the woods where they enjoyed their lunch,
just as if they were on a picnic. They visited the Botanical Gardens,
