"A trip where and how?"

"I don't know just where, but as to how—in the House on Wheels."

"Is she all ready?"

"We'll give her a tryout to-morrow. Maybe the thing won't work as well as I planned, but we'll soon know. If it comes anywhere near the mark I've set, will you go with me?"

"On a trip? Sure!"

"All right," said Tom, pacing the floor of his office. "Well have the tryout to-morrow. After that—well, we'll see!"
