"Wunst, an' that was enough fer me," he confessed, drawling his words. "Yer see it was this a-way. One time I was out there in that hell hole plum' alone fer a whole week, just a waitin' fer Mendez ter show up so I could ride into Haskell and tell Lacy he'd come. It was so damn lonesome I explored every nook an' cranny between them rocks, an' one day, lyin' out in front o' ther bunk-house, I happened to trace this ol' trail. I got a notion to give it a trial, an' I did that same afternoon. I got down all right, but it was no place fer a lady, believe me, an' I reckon no white man ever made it afore."

"It had been used once?"

"There was some signs made me think so; Injuns, I reckon, an' a long while ago."

Westcott asked: "How can we get there safely? Can you guide us?"

Moore swept his eyes over the dull range of sand, expectorated thoughtfully, and rammed his hands deep into his trouser-pockets. He was slow about answering, but the two men waited motionless.

"If it was me," he said finally. "I'd take it on foot. It'll be a jaunt ov near on to three miles, unless yer want ter risk bein' seen by them Mexes on the main trail. You couldn't go straight, but would have ter circle out an' travel mostly behind that ridge o' sand thar to the left. Goin' that a-way nobody's likely ter get sight o' yer on foot. You couldn't take no hoss, though. Here'd be my plan; lead this yere outfit o' mine an' your ponies back inter them sand dunes whar nobody ever goes. They're tired 'nough ter stand, an' there ain't anything fer 'em to graze on. Then we kin hoof it over ter the place I'm tellin' yer about, an' yer kin sorter size it up fer yerselves. That's fair, ain't it?"

They went at it with a will, glad to have something clearly defined before them, Brennan in his slow, efficient way, but Westcott, eager and hopeful, spurred on by his memory of the girl, whose rescue was the sole object which had brought him there. The team was driven into the security of the sand drifts and unhitched. The saddles were taken from the backs of the ponies, and what grain Moore had in the wagon was carefully apportioned among the four animals. Satisfied these would not stray, the men looked carefully to their supply of ammunition and set forth on their tramp.

This proved a harder journey than either Brennan or Westcott had anticipated, for Moore led off briskly, taking a wide circle, until a considerable ridge concealed their movements from the south. The sand was loose, and in places they sank deeply, their feet sliding back and retarding progress. All three were breathing heavily from the exertion when, under protection of the ridge, they found better walking.

Even here, however, the way was treacherous and deceiving, yet they pressed forward steadily, following the twists and turns of the pile of sand on their right. The distance seemed more than three miles, but at last Moore turned sharply and plunged into what resembled a narrow ravine through the ridge. Here they struggled knee deep in the sand, but finally emerged on the very rim overlooking the valley.

So perfectly was it concealed they were within ten feet of the edge before the men, their heads bent in the strenuous effort to advance, even realised its immediate presence. They halted instantly, awestruck, and startled into silence by the wonder of that scene outspread below. Moore grinned as he noted the surprise depicted on their faces, and waved his hand.
