But the country was of a deadly and a deceitful sameness, devoid of landmarks and lacking well-defined water-courses. The unending mesquite with its first spring foliage resembled a limitless peach-orchard sown by some careless and unbelievably prodigal hand. Out of these false acres occasional knolls and low stony hills lifted themselves so that one came, now and then, to vantage-points where the eye leaped for great distances across imperceptible valleys to horizons so far away that the scattered tree-clumps were blended into an unbroken carpet of green. To the woman these outlooks were unutterably depressing, merely serving to reveal the vastness of the desolation about her. At the crest of such a rise she paused and studied the country carefully, but without avail. She felt dizzily for the desert bag swung from her shoulder, only to find it flat and dry; the galvanized mouthpiece burned her fingers. With a little shock she remembered that she had done this very thing several times before, and her repeated forgetting frightened her, since it seemed to show that her mind had been slightly unbalanced by the heat. That perhaps explained why the distant horizon swam and wavered so. In all probability a man situated as she was would have spoken aloud, in an endeavor to steady himself; but this woman did nothing of the sort. Seating herself in the densest shade she could find--it was really no shade at all--she closed her eyes and relaxed--no easy thing to do in such a stifling temperature and when her throat was aching with drought. At length she opened her eyes again, only to find that she could make out nothing familiar. Undoubtedly she was lost; the water-hole might be anywhere. She listened tensely, and the very air seemed to listen with her; the leaves hushed their faint whisperings; a near-by cactus held its forty fleshy ears alert, while others more distant poised in the same harkening attitude. It seemed to the woman that a thousand ears were straining with hers, yet no sound came save only the monotonous crescendo and diminuendo of those locust-cries coming out of nowhere and retreating into the voids. At last, as if satisfied, the leaves began to whisper softly again. Away to her left lay the yellow flood of the Rio Grande, but the woman, though tempted to swing in that direction, knew better than to yield. At least twenty miles of barrens lay between, and she told herself that she could never cover such a distance. No, the water-hole was nearer; it must be close at hand. If she could only think a little more clearly, she could locate it. Once more she tried, as she had tried many times before, to recall the exact point where she had shot her horse, and to map in her mind's eye the foot-weary course she had traveled from that point onward.
