"Oh, yes, the Whizzer is pretty good size. There she is!" cried Mr. Fenwick proudly, as he threw open the doors of the shed, and Tom and Mr. Damon, looking in, saw a large triplane, with a good-sized gas bag hovering over it, and a strange collection of rudders, wings and planes sticking out from either side. Amidships was an enclosed car, or cabin, and a glimpse into it served to disclose to the young inventor a mass of machinery.

"There she is! That's the Whizzer!" cried Mr. Fenwick, with pride in his voice. "What do you think of her, Tom Swift?"

Tom did not immediately answer. He looked dubiously at the electric airship and shrugged his shoulders. It seemed to him, at first glance, that, it would never sail.

Chapter VII Making Some Changes

"Well, what do you think of it?" asked Mr. Fenwick again, as Tom walked all about the electric airship, still without speaking.

"It's big, certainly," remarked the lad.

"Bless my shoe horn! I should say it was!" burst out Mr. Damon. "It's larger than your Red Cloud, Tom."

"But will it go? That's what I want to know," insisted the inventor. "Do you think it will fly, Tom? I haven't dared to try it yet, though a small model which I made floated in the air for some time. But it wouldn't move, except as the wind blew it."

"It would be hard to say, without a careful examination, whether this large one will fly or not," answered Tom.
