The valley of the Rio Grande opened to view, wide near at hand in a great gray-green gap between the bare black mountains, narrow in the distance, where the yellow river wound away, glistening under a hot sun. Bo squealed in glee at sight of naked little Mexican children that darted into adobe huts as the train clattered by, and she exclaimed her pleasure in the Indians, and the mustangs, and particularly in a group of cowboys riding into town on spirited horses. Helen saw all Bo pointed out, but it was to the wonderful rolling valley that her gaze clung longest, and to the dim purple distance that seemed to hold something from her. She had never before experienced any feeling like that; she had never seen a tenth so far. And the sight awoke something strange in her. The sun was burning hot, as she could tell when she put a hand outside the window, and a strong wind blew sheets of dry dust at the train. She gathered at once what tremendous factors in the Southwest were the sun and the dust and the wind. And her realization made her love them. It was there; the open, the wild, the beautiful, the lonely land; and she felt the poignant call of blood in her--to seek, to strive, to find, to live. One look down that yellow valley, endless between its dark iron ramparts, had given her understanding of her uncle. She must be like him in spirit, as it was claimed she resembled him otherwise. At length Bo grew tired of watching scenery that contained no life, and, with her bright head on the faded cloak, she went to sleep. But Helen kept steady, farseeing gaze out upon that land of rock and plain; and during the long hours, as she watched through clouds of dust and veils of heat, some strong and doubtful and restless sentiment seemed to change and then to fix. It was her physical acceptance--her eyes and her senses taking the West as she had already taken it in spirit. A woman should love her home wherever fate placed her, Helen believed, and not so much from duty as from delight and romance and living. How could life ever be tedious or monotonous out here in this tremendous vastness of bare earth and open sky, where the need to achieve made thinking and pondering superficial? It was with regret that she saw the last of the valley of the Rio Grande, and then of its paralleled mountain ranges. But the miles brought compensation in other valleys, other bold, black upheavals of rock, and then again bare, boundless yellow plains, and sparsely cedared ridges, and white dry washes, ghastly in the sunlight, and dazzling beds of alkali, and then a desert space where golden and blue flowers bloomed.
