The Aeroplane Boys Flight

"It was my mistake, Frank!" "How do you make that out, Andy?" "Simply because I was using the little patent Bird monkey-wrench last in our shop, and should have put it back in the toolbox belonging to the aeroplane. The fact that it isn't here shows that I mislaid it. Give me a bad mark, Frank." "Well, I must say it's a queer stunt for you to forget anything, Andy Bird. But with dark coming along, and home some miles away, it's plain that we'll have to let the mending of that wing go till morning."
