the following week, Tom was kept busy over the airship. He made many important changes, and one of these was to use a new kind of gas in the balloon bag. He wanted a gas with a greater lifting power than that of the ordinary illuminating vapor which Mr. Fenwick had used.

"Well," remarked Tom, as he came from the airship shed one afternoon, "I think we can give it a try-out, Mr. Fenwick, in a few days more. I shall have to go back to Shopton to get some articles I need, and when I come back I will bring Mr. Damon with me, and we will see what the Whizzer can do."

"Do you mean we will make a trial flight?*'

"Yes."

"For how long a distance?"

"It all depends on how she behaves," answered Tom, with a smile. "If possible, we'll make a long flight."
