"I shall bring this matter to the attention of the Society for the Prevention of Cruelty to Animals back home," she said somewhat snappishly.

But there was no opportunity to exchange more remarks on the subject.

Uttering a shrill series of "ye-o-o-ows" the riders bore down on the little desert camp. From the heaving sides of the ponies, plastered with the gray alkali of the desert, clouds of steam were rising. Their riders, with mouths screened from the biting dust with red handkerchiefs, were seemingly engaged in a race for the willow clump where water and shade awaited them.

"Yip-yip-y-e-e-e-e-e-e!"

The sound came raucously from behind a dozen bandaged mouths as the band swept down oil tile camp. And then suddenly:

Bang! Bang! Bang!

A volley of revolver shots resounded as the jubilant horse hunters— as Alverado had shrewdly suspected they were—dashed forward.

"Oh, Land of Goshen!" screamed Miss Prescott, as, with her fingers in her ears, she fled into her tent and pulled the flap to. Peggy and Jess stood their ground boldly enough, although Jess's face turned rather pale and her breath heaved in perturbation.

"Keep still, honey, they won't hurt you," comforted Peggy amid the uproar.

Suddenly the leader of the horsemen drew his pony up abruptly, throwing the cat-like little beast almost back upon his haunches.
