"You'd better watch that fellow, Motor Matt," called Murgatroyd. "He'll not go to the post, but will clear out for parts unknown."

"He'll go to the post, I'm sure of it," said Matt.

"I will," declared Newt. "My father and I never agreed very well, but I guess that was my fault, too. When you leave here, Motor Matt, just lock the door and bring the key. I don't know whether I'll ever come back to this shack or not—I don't think I will, as I feel now—but it will be well for me to have the key. Good-by."

He stepped toward the king of the motor boys and extended his hand.

"Haven't you forgotten something, Newt?" inquired Matt.

Prebbles gave him a blank look. The next moment he understood what Matt had reference to, and pulled a jingling bag from his pocket and tossed it upon the table.

"That's the whole of it," he said. "You'll see that it is returned?"

Matt nodded.

"That means that I'll have to walk to Totten, or ride Murgatroyd's horse," Prebbles added, as he moved toward the door.
