“No; and they are the lineal ancestors of the neighbors we shall have presently.” Later the thought was to recur under conditions that would lend it enormous force. He forgot it in the moment of utterance, saying, as he glanced at his watch: “We have been doing pretty well. At this rate we’ll make the Barranca quite early.”

He had failed to allow, however, for the demon which, usually content with the complete possession of Paz and Luz, suddenly entered into the burros and sent them flying downhill through a grove of trees. Entering on one side fully loaded, they emerged at the other naked, and by the time they were rounded up and reloaded Seyd had to recast his schedule.

“We’ll be lucky if we make it now in daylight. We may have to camp at the top.”

Repeated in Spanish, the latter suggestion drew vigorous headshakes from both muleteers. Carlos made answer. “No, señor, at this time of the year one would perish of the cold, and there is an inn in the Barranca with the finest of accommodations. The trail? It is nothing! A peso for every time I have traveled it by night would buy me a rancho—and Paz and Luz, devils as they are, could travel it blindfold.” And whether, as Billy suggested, they were afraid of missing their usual communion with the fleas in the inn stables, both he and Mattias began to hustle the mules with oaths, hissings, whip-crackings. They kept after them so hard that the train trotted out of a forest of upland piñon upon the rim of a great valley a full half hour before sundown.

Though prepared by Seyd’s descriptions for something unusually fine, Billy’s blue eyes opened to the limit, and he sat silent upon his mule, staring, altogether bereft of his usual loquacity. From their feet the land broke suddenly and fell into purple depths from which dark hills uplifted ruddy peaks into the blaze of the setting sun. The Barranca was so deep, so vast in scale, that he grew dizzy in following with his eye the tiny zigzag of the trail down, down, till it was lost in blue haze through which even the giant ceibas and tall cedars showed like microscopic plants. Across the valley, miles away, naked mountains tossed and tumbled, seamed, scarred, gashed by slide and quake, sterile and desolate, as on the far day that some world convulsion raised them out of the sea.

“Drunk! drunk!” Billy breathed, at last. “Nature gone on a jag. Drunken mountains loose in a crazy world. The whole earth is turned on edge. Hold me, Bob, before I fall in. How deep do you call this bit of a hole?”

“About five thousand feet down to the floor. It falls off a thousand and more in a few miles to the coast. You see, we are still in touch with the old Pacific. Can’t be more than thirty miles or so down to the sea.”

“The dear old pond. Isn’t that pine on the other side?”
