"It's a great little ranch you have here." Thode turned in his chair to survey the close-packed avenues of low-hanging trees. "Any oil on your land, Mr. Hallock?"

"Not here. Got two gushers over near Tuxpam, next to some property that I reckon you'll want to look into for the Mexamer people. Larkin told me himself that he thought of taking it over."

The talk drifted into a discussion of relative values and prospects, and when Thode cantered down the driveway an hour or so later he had secured a good working knowledge of the surrounding country with which to commence his labors. He had parted with some little difficulty from his host, who insisted on sending in to Limasito for the young engineer's baggage and wholeheartedly desired that he make the Hacienda de Rosa his headquarters.

Kearn Thode, however, had other intentions. He must be free to go and come as he pleased on his mission and he determined to make the town itself the center of his activities. Moreover, Hallock's hacienda was a bachelor establishment and in Limasito there were girls; girls with blue eyes and black hair and incredibly white skin, who looked a man straight in the eyes and made him feel as if maybe he'd found a friend.

That blue adobe house on the southern end of the square began to loom large in the architecture of Limasito. Thode had caught a glimpse of the patio as he swung past; it had looked cool and green and inviting, with a fountain playing and little tables scattered about. What was it, anyway, and how could one meet a girl who lived there?

The curious old tale of the Lost Souls' Pool was temporarily forgotten in speculations of a more warmly personal nature. Was she an Americano? She seemed of too fair a type for a native daughter, in spite of her dark hair, and that, together with her violet-blue eyes, gave more than a hint of Irish ancestry. What could bring a girl of her sort to a boom town below the border?

So absorbed was the young engineer in his cogitations that he had reached the outskirts of Limasito before he awoke from his reverie. The swiftly falling curtain of twilight had wrapped the spreading orchards and haciendas in fragrant gloom and a myriad of mysterious chirpings and rustlings forecasted the coming night, when the harsh, grating screech of a horn blared upon their monotone and a low roadster appeared suddenly around a turn in the road, careening sharply on two wheels, and bore down recklessly upon the lone rider.

Thode's pony was quicker than he and leaped aside barely in time to avoid disaster as the car shot past and hurtled on into the dusk. He turned in his saddle and watched its unlighted shape swerve drunkenly from side to side of the road, until a further turn hid it from view. With a muttered imprecation, he gave the sure-footed pinto its head, and as it floundered out of the ditch the white, jeering face of the man at the wheel, as he had seen it in that flashing glimpse, rose again before his consciousness. It seemed for a startling instant to be grimly, portentously familiar, then the fancy faded before the fact of its obvious absurdity, and he laughed contemptuously. The danger of the moment had played tricks with his nerves.

A long-drawn, tremulous moan from the roadside broke in upon his thoughts and he halted the pinto abruptly. A small crumpled figure lay face downward in the ditch, twisting and quivering like a shot rabbit, and, bending over it, Thode saw a slender feminine form which made his pulse miss a beat or two and then race on with unaccountable acceleration. He flung himself from the saddle and reached the edge of the ditch, hat in hand, just as a pair of soft violet eyes were raised to his. It was the girl of the adobe house on the plaza.

"There has been an accident?" he stammered.
