"Does Cruz Mendez work for him?" interjected De Lancey desperately.

"No, indeed!" answered Don Juan patiently. "He packs in wood from the hills—but as I was saying—" and from that he went on to tell of the unfailing courtesy of the Señora Aragon to a gentleman whom, whatever his present station might be, she recognized as a member of one of the oldest families in Castile.

De Lancey did not press his inquiries any further, but the next morning, instead of riding back into the hills, he and Bud turned their faces down the cañon to seek out the elusive Mendez. They had, of course, been acting a part for Don Juan, since Kruger had described Old Fortuna and the Señor Aragon with great minuteness.

And now, in the guise of innocent strangers, they rode on down the river, past the concentrator with its multiple tanks, its gliding tramway and mountains of tailings, through the village of Indian houses stuck like dugouts against the barren hill—then along a river-bed that oozed with slickings until they came in sight of the town.

La Fortuna was an old town, yet not so old as its name, since two Fortunas before it had been washed away by cloudbursts and replaced by newer dwellings. The settlement itself was some four hundred years old, dating back to the days of the Spanish conquistadores, when it yielded up many mule-loads of gold.

The present town was built a little up from the river in the lee of a great ridge of rocks thrust down from the hill and well calculated to turn aside a glut of waters. It was a comfortable huddle of whitewashed adobe buildings set on both sides of a narrow and irregular road—the great trail that led down to the hot country—and was worn deep by the pack-trains of centuries.

On the lower side was the ample store and cantina of Don Cipriano, where the thirsty arrieros could get a drink and buy a panoche of sugar without getting down from their mounts. Behind the store were the pole corrals and adobe warehouses and the quarters for the peons, and across the road was the mescal still where, in huge copper retort and worm, the fiery liquor was distilled from the sugar-laden heads of Yuccas.

This was the town, but the most important building—set back in the shade of mighty cottonwoods and pleasantly aloof from the road—was the residence of Señor Aragon. It was this, in fact, which held the undivided attention of De Lancey as they rode quietly through the village, for he had become accustomed from a long experience in the tropics to look for something elusive, graceful, and feminine in houses set back in a garden. Nothing stirred, however, and, having good reason to avoid Don Cipriano, they jogged steadily on their way.

"Some house!" observed Phil, with a last, hopeful look over his shoulder.

"Uh," assented Bud, as they came to a fork in the road. "Say," he continued, "let's turn off on this trail. Lot of burro tracks going out—expect it's our friend, Mr. Mendez."
