The vigilants all vanished up the pass. It seemed ages after they had gone, when Pomp received another great surprise.

Suddenly, hearing the clatter of hoofs he turned his head, and scrutinized the prairie.

A thrilling sight met his gaze.

There, coming over a swell in the plain was a body of horsemen.

It required but a glance for the darky to recognize them.

They were the cowboys with Artemus Cliff at their head. They were riding directly down upon the Steam Man.

They were just coming from the scene of their victory over Clark. Pomp’s eyes stuck out like agates and he sprung to his feet.

“Glory fo’ goodness!” he gasped. “Dat am Cliff and his debbils. I jes’ reckon I get out dere way.”

In an instant he opened the throttle and let the Steam Man race out upon the prairie.

The cowboys gave a wild yell, and attempted pursuit.
