Once more the postman’s whistle sounded, and then Tommy, who was watching him eagerly, hoping that perhaps there might, after all, be a letter for the Trippertrot home, uttered a cry.
“See!” Tommy exclaimed. “The postman has dropped a letter from his bag, and he doesn’t know it. He’s going right on.”
“Oh, we must tell him about it!” decided Mary. “Knock on the window, boys, and call to him. He’ll understand.”
So Tommy and Johnny knocked on the pane of glass with their fingers, and Mary helped them, but they couldn’t make noise enough so that the postman could hear them. On he hurried, blowing his whistle, and he never thought that he had lost a letter in the street.
“Raise the window and call to him!” said Mary.
So Tommy and Johnny tried to do this, but the window was stuck fast, and they couldn’t open it. And all this time the postman was getting farther and farther away.
“Well, we’ve got to do it!” sighed Mary, at last.
“Do what?” asked Tommy and Johnny together.
“We’ve got to run after the postman, and give him the letter he lost,” said the little Trippertrot girl. “We’ve tried every way we knew to make him hear us, but he didn’t. Now we’ve got to go out. It’s a special, extra-extraordinary occasion, anyhow, I guess.”
“Shall we tell mamma we’re going?” asked Tommy.
