And David said it was funny how heavy books were, because they were made of paper, and paper was one of the lightest things there was, and his kitty liked to play with pieces of newspaper, out of doors, where the wind blew them. Then he got up and called his cat, but she didn't come. "I'll tell you," David said; "let's go and find her." So Dick and David each took hold of one handle of the cart, and walked along to David's house, and David called his cat again, but she didn't come. Then he thought that she must be in the woods, and they would go there and find her. But first he went into his house and asked the maid to give him and Dick some cookies, and the maid gave him three for Dick and three for himself. And he gave Dick his three, and the two little boys wandered on into the woods, eating their cookies and dragging the cart behind them, and David thought how much better a real little boy was than a pretend little boy. And David told Dick about the squirrels and the crows and the other birds that were there, and he showed him where there were some chestnuts; and they picked up some chestnuts and got them out of the burs and put them into the cart. Then suddenly there was David's cat walking along, with her bushy tail sticking straight up in the air; and she went to David and rubbed against him, and she went to Dick and rubbed against him, and she went to the cart and rubbed against that. Then she ran on ahead, and they came after, and they went to the place where the squirrels and the crows had been. But no squirrels were there. So the two little boys wandered on through the thin woods, looking for squirrels, and sometimes the cat was with them and sometimes she wasn't, and at last they were just behind Dickie's house, for the new house was his house now. And they looked up and saw the vans just starting away, and the horses were trotting. They watched until they couldn't see the vans any longer, and they heard them turn the corner. "I guess I've got to go," said Dickie then. "Why have you got to go?" David asked. "Aren't you going to live in that house?" "Yes," Dick said, "I am, but we're going back for to-night. To-morrow the maids will have it all ready, and we'll come and bring my mother and my baby sister." "Oh," said David. That was the first time Dick had told him that he had a baby sister. Dick had already started up to his house, but he stopped and turned around. "Good-bye, David," he said. "Good-bye, Dick," said David. And Dick turned again and hurried to the new house, but David stood, holding the handle of his cart and looking after him. And he saw Dick's father come around the corner of the house and take Dick by the hand. Then Dick's father stood for a minute looking at the house, as if he was afraid that he had forgotten something. But he couldn't think of anything, and he and Dick began to walk away, and Dick was talking to his father and his father was smiling.
