It was with this idea in mind that he had united his forces with Frank's inventive genius and helped build the monoplane with which they had won the race to the top of the neighboring mountain, during Old Home Week at Bloomsbury.

Since the Bird boys had constructed that monoplane themselves, after patterns obtained elsewhere, surely they had reason to be proud of their work and the gallant victory which had come to them.

The work-shop which we saw beside Locke's house contained a monoplane in course of construction; but there was something lacking which he felt Morris's plans could supply; and so he was anxious to get hold of it by hook or crook.

Frank believed he ought to tell about the dastardly attempt to destroy the monoplane.

The Germans also fancy their monoplane as a bird; but they call it Taubea dove.

He never knew whether he jumped purposely or lost his grip of that upright after the shock of the collision; but the next thing he realized he was straining himself with might and main to hold back the monoplane, already gliding along with sundry violent bumps, on the three bicycle wheels.

When Andy heard about the attempt to injure the monoplane he was in a tremble.

Far behind lagged a monoplane.

He was determined to be thorough in all he did, and this consumed more or less time, so that when he finally pronounced the monoplane in perfect condition the afternoon was half gone.

Looking up, they saw a dainty green monoplane, with widespread wings and whirring propeller, descending to earth.

His heart was so set upon having a chance to use the monoplane in the endeavor to discover that strange cliff-enclosed valley, where his father was imprisoned, that he did not mean to take any chances of losing out through over confidence.
