"Perfectly, Miss Farley. I have you to consider, and I presume no peaceful Indians come into these bad lands." "Pimas and Moquis cut their hair square across the forehead. If you see any others, shoot--to kill!" "I will," said Lennon, certain that he understood the cause of the girl's almost fierce insistence. He knew that the treatment of captured women by renegade Indians is a far worse fate than death. Carmena took note of his set jaw, drew in a deep breath, and swung around to angle up the slope at the side of the canon head. Half an hour of winding advance through the midst of the scraggly low-growing trees brought them to the notch in the rim-ridge. Below this break the mesa side pitched steeply into a great basin that was blotched with white alkali flats, wave-marked with sand dunes, and broken with jagged hills and skeleton-like ridges. The air was so dry and clear that even far out in the Basin, many miles away, Lennon could distinguish patches of green. Nearer at hand appeared blurs of a grayish vegetation. But at his pleased exclamation Carmena told him that he was looking at no oasis. What he saw was only the green of mesquite and palo verde, the fluted columns of the giant sahuaro, and the gray of sagebrush. In all that wide waste of desolation no trickling rill or even the smallest of pools glinted under the fierce rays of the mid-day sun. Over beyond the north side of the Basin, above the lesser peaks and buttes, appeared a higher mountain. The top, dwarfed by distance but as clear cut in outline as a cameo, was divided into three thick tower-like masses. "There's your Triple Butte," said Carmena. "What! So near as that? We can make it by mid-afternoon." The girl smiled. "You might, if you hurried enough. It's only forty miles away on a beeline." Lennon stared, openly incredulous: "Forty miles?" "Near fifty-five by way of the water-holes--forty to the ranch. We'll strike for the nearest tank. I've noticed your canteen has been empty some time. Here's mine." Though Lennon's throat was parched, he sought to refuse the offered canteen, which was still half full. Carmena dropped it at his feet and began to zigzag down the mesa side. Noon had passed before they gained the foot of the steep slope. Carmena followed out along a ridge of bare rock, past scattered growths of thornscrub and cactus, to where windblown sand lay in sterile drifts alongside the ledges. Here she turned up a narrow cleft of the ridge and entered the mouth of a small cave. She knelt to dip her hat down a hole in the bottom of the cave. The hat came up brimful of water. She drank deeply, refilled the hat, and backed out past Lennon to water the eager pony. "I'll thank you to fill the canteens and give the bronc as much more as he can drink," she directed. "There's firewood on around that point of rocks. Keep your gun handy."
