Rh "Oh, if I can help a fellow inventor, and assist in making a new model of airship fly, I'm only too glad to do it without pay," retorted Tom, quickly. "I didn't come here for that. Suppose we go in the cabin, and look at the motor. That's the most important point, if your airship ts to navigate."

There was certainly plenty of machinery in the cabin of the Whizzer. Most of it was electrical, for on that power Mr. Fenwick intended to depend to sail through space. There was a new type of gasolene engine, small but very powerful, and this served to operate a dynamo. In turn, the dynamo operated an electrical motor, as Mr. Fenwick had an idea that better, and more uniform, power could be obtained in this way, than from a gasolene motor direct. One advantage which Tom noticed at once, was that the Whizzer had a large electric storage battery.

This was intended to operate the electric motor in case of a break to the main machinery, and it seemed a good idea. There were various other apparatuses, machines, and appliances, the nature of which Tom could not readily gather from a mere casual view.

"Well, what's your opinion, now that you have seen the motor?" asked Mr. Fenwick, anxiously.

"I'd have to see it in operation," said Tom.
