"This is another case where Carl's using his head," put in Matt. "He's playing some dodge or other."

"He's showing up a whole lot stronger than I ever imagined he could," said the cowboy. "I had sized him up for a two-spot at any sort of headwork. Got my opinion, I reckon, from the way those Chicago detectives fooled him."

"He's not so slow as you imagine, Joe," said Matt. "Now keep an eye out for scraps!"

"We can't get into a scrap with those Hindoos any too quick to suit me," laughed McGlory, hanging out over the side of the motor car.

Once more the whirling, headlong rush of the car was resumed. No sooner had Burton, or McGlory, discovered a bit of white in the roadway ahead than it was lost to sight behind.

Then, after four or five miles of this, the three in the car raised an object, drawn up at the roadside, which brought the car to a halt. The object was the monkey wagon, horse gone from the shafts, rear door swinging open, and not a soul in the vicinity.

"Here's another queer twist," grumbled Burton, as all three got out to make a close survey of the wagon. "What do you think of it, Matt?"

Matt and McGlory thrust their heads in at the door.

"Phew!" gurgled the cowboy, drawing back. "There's a mineral well, in Lafayette, that's a dead ringer for the smell inside that cage wagon."

"I haven't had it swabbed out yet," apologized Burton.
