“From your horses!” he calls out, “take shelter behind them, and cover your faces with your jergas! If you don’t you’ll be blinded outright.”

His counsel acts as a command; though it is not needed, all of them, as himself, sensible of the approaching peril. In a trice they have dropped to the ground, and plucking the pieces of skins which serve them as saddles, from the backs of their horses, muffle up their faces as admonished. Then each clutching the halter of his own, and holding it so as to prevent the animal changing position, they await the onslaught of the storm.

Meanwhile, Aguara has not been inactive. Instead of having seized the pony’s bridle-rein, he has passed round to the rear of the troop, leading his captive along with him; for the wind strikes them in front. There in the lee of all, better sheltered, he dismounts, flings his arms around the unresisting girl, and sets her afoot upon the ground. He does all this gently, as though he were a friend or brother! For he has not lost hope he may yet win her heart.

“Star of my life,” he says to her, speaking in the Tovas tongue, which she slightly understands. “As you see we’re in some danger, but it will soon pass. Meanwhile, we must take steps to guard against it. So, please to lie down, and this will protect you.”

While speaking, he takes the plumed cloak from his shoulders and spreads it over those of the captive, at the same time covering her head with it, as if it were a hood. Then he gently urges her to lie on the ground.

To all she submits mechanically, and without offering opposition; though she little cares about the dust-storm—whether it blind or altogether destroy her.

Soon after it is on and over them in all its fury, causing their horses to cower and kick, many screaming in affright or from the pain they have to endure. For not only does the tormenta carry dust with it, but sand, sticks, and stones, some of the latter so large and sharp as often to inflict severe wounds. Something besides in that now assailing them; which sweeping across the salitral has lifted the sulphureous efflorescence, that beats into their eyes bitter and blinding as the smoke of tobacco. But for having muffled up their faces, more than one of the party would leave that spot sightless, if not smothered outright.

For nearly an hour the tempest continues, the wind roaring in their ears, and the dust and gravel clouting against their naked skins, now and then a sharp angled pebble lacerating them. At times the blast is so strong they have difficulty in keeping their places; still more in holding their horses to windward. And all the while there is lightning and thunder, the last loud and rolling continuously. At length the wind, still keenly cold, is accompanied by a sleety rain, which pours upon them in torrents, chill as if coming direct from the snowy slopes of the Cordilleras—as in all likelihood it does.

They know that this is a sign of the tormenta approaching its end, which soon after arrives; terminating almost as abruptly as it had begun. The dust disappears from the sky, that which has settled on the ground now covering its surface with a thick coating of mud—converted into this by the rain—while the sun again shines forth in all its glory, in a sky bright and serene as if cloud had never crossed it!

The tormenta is over, or has passed on to another part of the great Chaco plain.
