"That you get all the equipment for a first-class playground," answered the superintendent of parks.

Dr. Tucker was thinking very fast. "Equipment for a first-class playground" meant swings and bars and teeter boards and tennis nets and footballs and ever so many other things boys and girls love in a playground. With the same twinkle that was in his eyes when he looked at the park and said, "I'll do it," he said now, "All right, I'll take you up."

He did not have a single cent in his pocket to buy all these things and he did not know where he was going to get so much money, but he said to himself:

"I'll look around a bit and see what I can see."

The first thing he saw was some men tearing up an old street-car track. He went to the manager of the street-car company. "What are you going to do with those old rails?" he asked. "May I have them?"

"Yes, I guess so," answered the manager.

Dr. Tucker said "Thank you" very politely and then added, "I'll have to have them shaped a little differently and a few holes bored in them. Would you mind doing this in your shop?"

The manager said he would do that, too. When Dr. Tucker said "Thank you" very politely again and turned to go, the manager asked: "What in the world do you want those old rails for?"

"For swing supports and all sorts of equipment for the playground."

He told the manager about his ride with the mayor and the superintendent of parks and all about the things he was going to make for the playground and athletic fields out of those lovely old rails.
