The young inventor made another trip to Mr. Fenwick's house the first of the following week. He went by train this time, as he had to ship his tools, and Mr. Damon did not accompany him. Then, with the assistance of the inventor of the Whizzer, and several of his mechanics, Tom began making the changes on the airship.
"Do you think you can make it fly?" asked Mr. Fenwick, anxiously, after several days of labor.
"I hope so," replied our hero, and there was more confidence in his tone than there had been before. As the work progressed, he began to be more hopeful. "I'll make a trial flight, anyhow, in a few days," he added.
"Then I must send word to Mr. Damon," decided Mr. Fenwick. "He wants to be on hand to see it, and, if possible, go up; so he told me."
"All right," assented Tom. "I only hope it does go up," he concluded, in a low tone.

During 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?"
