Massa Dick, am dat contraption yo' boys dun put togedder back ob de bahn yesterday? Why, Aleck don't you know what that is? returned Dick Rover with a smile at the colored man. That's a biplane. A biplane, eh? repeated Alexander Pop, the colored helper around the Rover homestead. He scratched his woolly head thoughtfully. Yo' don't mean to say it am lak a plane a carpenter man uses does yo', Massa Dick? Pears lak to me it was moah lak some ship sails layin down somethin' lak dem ships we see over in Africy when we went into dem jungles to find yo' fadder. No, it has nothing to do with a carpenter's plane Aleck, answered Dick, with a laugh. A biplane is a certain kind of a flying machine.
