"Humph! It's about time. I've sunk almost enough money in that shebang to dig a gold mine, and I haven't got any out yet—not a cent, and I'm losing interest all the while."

"Well, but think of the twenty thousand dollars!"

"Yes, I s'pose I've got to. That's the only consolation I have left."

The above conversation took place one afternoon between Ezra Larabee and Lieutenant Larson. The airship with the mercury stabilizers was nearly completed. But a few touches remained to be put on her, to make her, according to Larson, ready for the flight across the continent.

"I presume you will go with me when me make the first ascent; will you not?" the lieutenant inquired.

"Who, me? No, I don't reckon I'll go up first," said Uncle Ezra slowly. "I'll wait until I see if you don't break your neck. If you don't I'll take a chance."

"That's consoling," was the answer, with a grim laugh. "But I am not afraid. I know the craft will fly. You will not regret having commissioned me to build her."

"Wa'al, I should hope not," said Uncle Ezra, dryly. "So far I've put eight thousand, four hundred thirty-two dollars and sixteen cents into this shebang, and I ain't got a penny out yet. It just seems to chaw up money."

"They all do," said the lieutenant. "It is a costly sport. But think of the twenty-thousand-dollar prize!"

"I do," said Uncle Ezra, softly. "That's all that keeps me from thinking what a plumb idiot I've been—thinking of that twenty thousand dollars."
