"Boys, it's Herr Muller!" shouted Nat.

"Wall ther blamed Dutchman!" gasped Cal, "has he bin stealin' horses?"

"Yep," rejoined the puncher briefly, "he hev. An' we're goin' ter string him up. Now you git out."

"All right," spoke Nat suddenly, with a flashing light of excitement blazing in his eyes.

"We'll get, but it will be—THIS WAY!"

As he spoke he leaped into the driver's seat, pushing Joe to one side.

The next instant the car was leaping forward with a roar and a bound, headed full at the band of amazed and thunderstruck cowpunchers.
