Dora looked at the small pond before them. She didn’t see any frogs.

“Just think, Dora,” said Miss Chandler, “that pond has been here since the first people came to Boston. The boys always slide on it in winter. Once during the Revolutionary War, British soldiers camped on the Common. They spoiled the ice where the children wanted to slide.”

“I know what happened,” said Lucy proudly. “The general in command of the British army was a very cross man, but the boys didn’t care if he was. They went straight and told him what the soldiers had done. And the General said they were to let the slide alone. Didn’t he, Aunt Margaret?”

“He did,” said Miss Chandler.

Dora looked respectfully at the Frog Pond. There were better places in Westmore for sliding when winter came, but it was interesting to know that children had played with the Frog Pond ever since there were any children in Boston to play there.

Beyond the Common lay a pretty park, called the Public Garden, and here they came to a larger body of water with white birds swimming on it. Some were ducks and some were swans, and the children stopped to watch them. Miss Chandler kept looking at a wooden platform not far away. Part of it was on the bank and part floated on the water.

Presently a boat came in sight, but it was like no boat Lucy and Dora had ever seen. It was not like the launch on World’s End Pond nor like the one at the beach. It looked like a tremendous great bird, floating lightly on the water.

“Would you like to go in the swan boat?” asked Miss Chandler.

Would they like to! Dora and Lucy could hardly speak for joy. But Dora asked one question.
