"Well, it wasn't originally," admitted Tom, "but the improvements
I put on it made it so. But, dad, when are we going on our tour?
You look more worn out than I've seen you in some time, not
excepting when the turbine model was stolen. Are you worrying
over your gyroscope invention?"

"Somewhat, Tom. I can't seem to hit on just what I want. It's a
difficult problem."

"Then I tell you what let's do, dad. Let's drop everything in the
inventive line and go off on a vacation. I'll take you up the
lake in my boat and you can spend a week at the Lakeview Hotel at
Sandport. It will do you good."

"What will you do, Tom?"

"Oh, Ned Newton and I will cruise about and we'll take you along
any time you want to go. We're going to camp out nights or sleep
in the boat if it rains. I've ordered a canopy with side
curtains. Ned and I don't care for the hotel life in the summer.
Will you go?"

been working hard and his brain was weary with thinking of many
problems. His son's program sounded very attractive.

"I think I will accept," said the inventor with a smile. "When
can you start, Tom?"
