One day in July a fair young girl, with beautiful gray eyes, sat musingly beside one of these southern trails gazing upon the inverted pyramid of red sky which glowed between the sloping shoulders of the westward warding peaks. Her exquisite lips, scarlet as strawberry stains, were drawn into an expression of bitter constraint, and her brows were unnaturally knit. Her hat lay beside her on the ground, her brown hair was blowing free, and in her eyes was the look of one longing for the world beyond the hills. She appeared both lonely and desolate. It was a pity to see one so young and so comely confronting with sad and sullen brow such aërial majesty as the evening presented. It was, indeed, a sort of impiety, and the girl seemed at last to feel this. Her frowning brow smoothed out, her lips grew more girlish of line, and at length, rapt with wonder, she fixed her eyes on a single purple cloud which was dissolving, becoming each moment smaller, more remote, like a fleeing eagle, yet burning each instant with even more dazzling flame of color than before--hasting as if to overtake the failing day. A dream of still fairer lands, of conquest, and of love, swept over her--became mirrored in her face. She had at this moment the wistful gaze which comes to the eyes of the young when desire of the future is strong. Upon her musings a small sound broke, so faint, so far, she could not tell from whence it came nor what its cause might be. It might have been the rattle of a pebble under the feet of a near-by squirrel or the scrambling rush of a distant bear. A few moments later the voice of a man--very diminished and yet unmistakable--came pulsing down the mountain-side. The girl rose as lightly, as gracefully as a fawn who, roused but not affrighted, stands on her imprint in the grass and waits and listens. The man or men--for another voice could now be heard in answer--came rapidly on, and soon a couple of men and a small pack-train came out of a clump of thick trees at the head of a gulch, and, doubling backward and forward, descended swiftly upon the girl, who stood, with some natural curiosity, to let the travellers, whoever they might be, pass and precede her down to the valley. She resented them, for the reason that they cut short her reverie, her moment of spiritual peace. The man who first appeared was a familiar type of the West, a small, lean, sharp-featured, foxy-eyed mountaineer, riding gracefully yet wearily--the natural horseman and trailer. Behind him two tired horses, heaped with a camp outfit, stumbled, with low-hanging heads, while at the rear, sitting his saddle sturdily rather than with grace, rode a young man bareheaded, but otherwise in the rough-and-ready dress of a plainsman. His eyes were on the sunset also, and something in the manner of his beard, as well as in the poise of his head, proclaimed him to be the master of the little train, a man of culture and an alien.
