“Oh, we'll have no trouble about the generator once I get what I'm after.”
“Sure of that?”
“Oh yes,” said Bill, gloomily.
“Then what's the trouble?” asked Tommy, alarmed by Bill's look.
“I certainly do get the vaporization all right, all right.”
“Great Scott! isn't that what you wanted?”
“Yes.”
“Then we've got it!”
“Yes, but I don't know what does it,” said Bill in despair.
