“I suppose we could get them up at Melbourne—or I could,” conceded the captain, his grin broadening into a laugh.

“Then it’s a go?” urged Andy.

“I reckon I did it just to be tinkerin’.”

“Well, you’ll get tinkerin’ to beat the band buildin’ an airship,” exclaimed Andy. “Besides, there ain’t any law against you takin’ a ride in it.”
