"How soon can we put it in commission?" she demanded eagerly,

"I'll disk it to-morrow. The ground is soft now, after this recent rain. Then I'll harrow it well and run a culti-packer over it—well, by the end of the week it ought to be a fairly fast track."

"Goody! We'll go in to El Toro to-morrow and I'll wire to San Francisco for a stop-watch. May I sprint Panchito a little across that meadow?"

"Wait a moment, Miss Kay. We shall have something to sprint after in a few minutes, I think." As the hounds gave tongue in a path of willows they had been investigating far to the right, Don Mike pulled up his horse and listened. "Hot trail," he informed her. "They'll all be babbling in a moment."

He was right.

"If it's a coyote, he'll sneak up the wash of the river," he informed the girl, "but if it's a cat, he'll cut through that open space to tree in the oaks beyond—Ha! There goes a mountain-lion. After him!"

His alert pony went from a halt to a gallop, following a long, lithe tawny animal that loped easily into view, coming from the distant willow thicket. In an instant, Kay was beside him.

"Head him off," he commanded curtly. "This ruin of Pablo's is done in a quarter-mile dash, but Panchito can outrun that cat without trying. Don't be afraid of him. They're cowardly brutes. Get between him and the oaks and turn him back to me. Ride him down! He'll dodge out of your way."

She saw that he was uncoiling his riata as he spoke, and divined his purpose, as, with a cluck and a boot to Panchito, she thundered after the big cat, her heart thumping with mingled fear and excitement. Evidently this was an old game to Panchito, however, for he pinned his ears a little and headed straight for the quarry. Seemingly he knew what was expected of him, and had a personal interest in the affair, for as he came up to the animal, he attempted to run the panther down. The animal merely snarled and gave ground, while gradually Panchito "hazed" him until the frightened creature was headed at right angles to the course he had originally pursued. And now Don Mike, urging the pinto to top speed, came racing up and cut him off.

"Catch him; catch him!" Kay screamed excitedly. "Don't let him get away!" She drove Panchito almost on top of the panther, and forced the beast to stop suddenly and dodge toward the approaching Farrel. As Panchito dashed by, Kay had a glimpse of Don Mike riding in, his looped riata swinging in wide, slow concentric circles—casually, even. As she brought Panchito round on his nimble heels, she saw Don Mike rise in his stirrups and throw.
