Under ordinary circumstances this accident would not have been of much moment. But to have pulled the other mules around, and so throw the runaways, would have spoiled the picture. William was too old a movie worker to do that.

When Ruth stumbled to the front of the swaying wagon and seized his shoulder he cast rather an embarrassed glance back at her.

"Stop them! Stop!" the girl commanded.

"I'd like mighty well to do it, Miss Fielding," said William, wagging his head, "but these dratted mules have got their heads and—they—ain't—-no notion o' stoppin' this side of the ranch corrals."

Ruth understood him. She stared straight ahead with a gaze that became almost stony. This leading wagon was heading for the break of a ravine into which the trail plunged at a sharp angle. If the mules were swerved at the curve the heavy wagon would surely overturn.

In twenty seconds the catastrophe would happen!

PURSUING DANGER

When a mule is once going, it is just as stubborn about stopping as it is about being started if it feels balky.

All six were utterly unmanageable.
