of the raiders. Polly saw him and her heart warmed.

"I knew he wasn't a coward!" she almost sobbed. "Oh, I'm glad--but he
needn't be such an idiot as that. He'll be shot as sure as I'm here."

Panic stricken, she increased her pace and in a minute had reached the
shelter of the car. Then the shots burst upon her ears. She turned white
and clung to the door of the car. If they had killed him! She saw Scott's
face as he had left her--friendly, ugly, determined--and she knew that if
they had killed him nothing else would matter--anything might happen and
she would not care. Mechanically, she opened the door of the car and
hastily moved some of the plunder from the floor to the seat. The Mexicans
had tossed in canned goods, blankets, rifles, a couple of cash boxes and
even a box of victrola records. Then she crawled into the space she had
made and seizing one of the blankets, drew it over herself and over a part

Polly's teeth chattered with fear; she was realizing with every throb of
the engine the awful risk she was taking.

Suddenly the car moved. Polly cowered in her uncomfortable position. Cold
with terror she clutched the revolver Scott had given her. Suppose at the
last minute some of the other men should decide to get into the car?

"But I won't suppose! There wouldn't have been any time to suppose if I'd
gone to war to drive an ambulance. The boys didn't suppose when they went
over the top--they just went! I hope to goodness none of these guns I'm
sitting on are loaded."

The car bumped along on the rutty road and the noise of the riders died
away.

"I knew it," the girl said triumphantly. "I knew the horseback people
would take to the trail as soon as they could, and the automobile can't,
of course. I've scored one point----"

The car stopped. Polly's breathing apparatus stopped simultaneously. What
was it? Had he seen her? Or was he about to pu
