“There you go with that ‘we’ stuff,” came from Mr. Holton. “Aren’t you fellows taking a lot for granted?”

“Oh, I don’t know,” returned Joe. “Judging from the past we’re not. You will take Bob and me along, won’t you? That is, of course, if you go.”

“We can’t say just now,” his father returned. “It might be arranged. All that can be decided later.”

“Hurrah for Africa!” cried Bob with enthusiasm. “We’ll——”

He stopped quickly, as he happened to glance at a small clock that was on the dresser.

“Past eight!” he cried. “Wow! We’ve got to be in Chinatown by nine!”
