David laughed. "Water-pipe men are funny men," he said.
One of the men lifted his head out of the hole in the floor and smiled at David, but he didn't say anything.
"They're putting in the waste pipe and the trap," the foreman said; "that is, the pipe that the water will run through when it runs out of the bathtub. A tub will be here Davie, after the floor is laid."
David nodded.
"Would you like to be a plumber, Davie?" the foreman asked, smiling.
David shook his head.
"I think I'd better go now," he said. "My kitty won't know where I am."
So the foreman laughed, and he tucked David under his arm and carried him downstairs and out of the front door, and he set him down on the ground.
"Good-bye, Davie," said the foreman.
"Good-bye," said David.
