“I’ll prove it all right,” Dick persisted. “We’ll start at the big bridge and go up the river to Slicer’s Landing; that’s six miles and a quarter, and if we don’t do it in an hour I’ll—I’ll lose my bet.”

“Oh, that’s all right,” answered Chub affably, “but what I’m saying is that she isn’t making any six miles an hour now. I don’t know what she might do to-morrow. Why, you might grease her hull, or get Roy to swim under water and tow her. Besides, I wouldn’t bet with a Westerner, anyway; he’s too tricky.”

“You always try to turn everything into a joke,” Dick growled. “When you say we’re not making six miles you don’t know what you’re talking about. Does he, Roy?”

“Don’t ask me,” said Roy. “I don’t know anything about it. I would like to suggest, however, that you turn the boat a bit so as to avoid running into that point. Thank you, Dickums; I feel more comfortable.”

“It’s a mighty poor launch that won’t make six miles,” muttered Dick as he swung the boat’s head farther toward the middle of the river.

“Dick, you’re stubborn to-day,” sighed Chub. “I refuse to argue with you any longer. I will only remark in closing that this here boat is not making any six miles per.”

“And I say she is,” answered Dick warmly. “If she isn’t I’ll—”

The chugging of the engine stopped, there was an expiring wheeze from somewhere and the launch rocked silently and lazily on the water.
