My! How the pinwheel buzzer did whirl around! Faster and faster it went until you could hardly see it. But alas and alack a-day! The airship didn't go up.

"What's the matter?" asked Jimmie anxious like.

"Oh, I see!" cried Jumpo, looking over the side. "I put too much court plaster on the roller skate wheels, and they're all stuck up. I'll soon fix it."

Well, it didn't take him long, and once more he started the engine. Faster and faster went the buzzer. The airship began to shiver and to shake, and then all of a sudden it began rolling over the ground.

"Oh, we're moving! We're moving!" cried Jimmie.

"Of course we are," said Jumpo proudly. "I told you we'd fly like a bird."

And then, would you believe me, that queer airship did go in the air a little distance because the wind got under the umbrellas and lifted them up. Up and up it went, with Jimmie and Jumpo in it.

"Wow! Isn't this great?" cried Jumpo.

"Yes, we're right over our duck pond," said Jimmie. "I hope we don't fall."

But alas! Just as he said that, something happened. The engine went so fast that the spring flew out of it. One umbrella turned inside out and the other outside in. The sticking plaster fell off, and the roller skate wheels dropped into the pond with a splash. Then the whole airship began falling into the pond.
