Dinsmore swung round his horse and galloped back, disengaging one foot from the stirrup. The girl caught the hand he held down to her and leaped up beside the saddle, the arch of her foot resting lightly on the toe of his boot. Almost with the same motion she swung astride the cow-pony. It jumped to a gallop and Ramona clung to the waist of the man in front of her. She could hear plainly now the yells of the exultant savages.

The outlaw knew that it would be nip and tuck to reach Palo Duro, close though it was. He abandoned at once his hopes of racing up the cañon until the Apaches dropped the pursuit. It was now solely a question of speed. He must get into the gulch, even though he had to kill his bronco to do it. After that he must trust to luck and hold the redskins off as long as he could. There was always a chance that Ellison's Rangers might be close. Homer Dinsmore knew how slender a thread it was upon which to hang a hope, but it was the only one they had.

His quirt rose and fell once, though he recognized that his horse was doing its best. But the lash fell in the air and did not burn the flank of the animal. He patted its neck. He murmured encouragement in its ear.

"Good old Black Jack, I knew you wouldn't throw down on me. Keep a-humpin', old-timer.... You're doin' fine.... Here we are at Palo Duro.... Another half-mile, pal."

Dinsmore turned to the left after they had dropped down a shale slide into the cañon. The trail wound through a thick growth of young foliage close to the bed of the stream.

The man slipped down from the back of the laboring horse and followed it up the trail. Once he caught a glimpse of the savages coming down the shale slide and took a shot through the brush.

"Got one of their horses," he told 'Mona. "That'll keep 'em for a while and give us a few minutes. They'll figure I'll try to hold 'em here."

'Mona let the horse pick its way up the rapidly ascending trail. Presently the cañon opened a little. Its walls fell back from a small, grassy valley containing two or three acres. The trail led up a ledge of rock jutting out from one of the sheer faces of cliff. Presently it dipped down behind some great boulders that had fallen from above some time in the ages that this great cleft had been in the making.

A voice hailed them. "That you, Homer?"

"Yep. The 'Paches are right on our heels, Steve."
