It was the figure of a handsome young horseman as abstracted as himself, but evidently on better terms with his own personality. He was dark haired, sallow cheeked, and blue eyed,--the type of the old Spanish Californian. A burnt-out cigarette was in his mouth, and he was riding a roan mustang with the lazy grace of his race. But what arrested Clarence's attention more than his picturesque person was the narrow, flexible, long coil of gray horse-hair riata which hung from his saddle-bow, but whose knotted and silver-beaded terminating lash he was swirling idly in his narrow brown hand. Clarence knew and instantly recognized it as the ordinary fanciful appendage of a gentleman rider, used for tethering his horse on lonely plains, and always made the object of the most lavish expenditure of decoration and artistic skill. But he was as suddenly filled with a blind, unreasoning sense of repulsion and fury, and lifted his eyes to the man as he approached. What the stranger saw in Clarence's blazing eyes no one but himself knew, for his own became fixed and staring; his sallow cheeks grew lanker and livid; his careless, jaunty bearing stiffened into rigidity, and swerving his horse to one side he suddenly passed Clarence at a furious gallop. The young American wheeled quickly, and for an instant his knees convulsively gripped the flanks of his horse to follow. But the next moment he recalled himself, and with an effort began to collect his thoughts. What was he intending to do, and for what reason! He had met hundreds of such horsemen before, and caparisoned and accoutred like this, even to the riata. And he certainly was not dressed like either of the mysterious horsemen whom he had overheard that moonlight evening. He looked back; the stranger had already slackened his pace, and was slowly disappearing. Clarence turned and rode on his way. CHAPTER IX.
