However, Joe had gone, and they could not hope to find him. Sunny Boy and Mother walked a bit about the pretty rocky paths and peeped into one or two of the little rustic cabins they found perched in unexpected places, and then Mother glanced at her watch and said it was time to go home.
"Are you tired, dear?" she asked as they started to walk to the nearest entrance.
"I guess my feet are," confided Sunny Boy. "They trip."
They saw one other thing that interested them very much before they left the park.
"What's that mon'ment?" Sunny Boy asked suddenly, pointing to a tall shaft that ended in a point at the top.
"That's the Egyptian obelisk," returned Mrs. Horton. "Come and look at it, dear. It is called 'Cleopatra's Needle,' and was brought all the way from Egypt. It is very, very old."
"How old?" demanded Sunny Boy practically. "It looks all right, Mother."
"Well, I've read that it was erected in Cairo, Egypt, sixteen hundred years before the birth of Christ," said Mrs. Horton. "So you see, dear, we are looking at a stone that is more than three thousand years old."
They took a surface car down to the hotel, and Sunny Boy, who did not like to say he was tired, was glad to curl up in a chair and look at a book till Daddy and Mother were ready to go to dinner.
Everyone went to bed early that night, for Mr. Horton had had a busy day, too, and was tired. He was not able to go about with them the next day, but on the following Monday he took them over to the Brooklyn Navy Yard and Sunny Boy actually went on board a battleship. The afternoon of the same day they crossed the wonderful Brooklyn Bridge and, getting out of the trolley car half way over, saw New York City from the middle of the river.
