The ci-devant cibolero does as directed, going at a gallop; while the colonel and his adjutant trot on to the clump of blackjacks, standing some three hundred paces out of the line of march. It was the same copse that gave shade and concealment to Frank Hamersley and Walt Wilder on the day preceding.
On arriving at its edge, which they do before their followers, Uraga and Roblez see the tracks of the two mules. Not without surprise, and they exchange some words regarding them. But the fast-darkening sky drives the subject out of their thoughts, and they occupy themselves in choosing a spot for pitching the tents.
Of these there are too—one which Urago owns, the other, found in the ranche, an old marquee Miranda had carried with him in his flight. This has been brought along for the accommodation of his sister, whom Uraga has reason to treat tenderly.
Both tents are soon set up in the shelter of the black-jacks; the marquee, as ordered by Uraga, occupied by the female captives.
The lancers, having hastily dismounted, picket their horses and make other preparations for the storm, predicted by the ex-cibolero as something terrific.
Before long they see his prediction verified to the spirit and the letter.
The sky, hitherto shining like a sapphire and blue as a turquoise, becomes changed to the sombre hue of lead; then darker, as if night had suddenly descended over the sterile plain. The atmosphere, but a moment before unpleasantly hot, is now cold as winter; the thermometer is less than twenty minutes falling over forty degrees—almost to freezing point!
It is not night which causes the darkness, nor winter the cold. Both come from an atmospheric phenomenon peculiar to the table-lands of Texas, and far more feared by the traveller. It is that called by Mexicans and styled by the ex-cibolero El Norte; by Texans known as “The Norther.”
Alike dreaded by both.
