They were hours descending, but the hours seemed days. At length the path lost itself in the blackness of a cavern-mouth. Cristoval found himself in a reverberating tunnel driven three hundred yards through living rock. Openings on the right admitted air and the growing thunder of the torrent. In the open again for another giddy, stumbling clamber down a hundred fathoms; and the bridge! Cristoval whispered a prayer. From a narrow shelf it swung out over the chasm in a long, sweeping curve to its anchorage on the farther side, a mere gossamer swaying in the breeze and vibrating fearfully beneath the soldiers’ tread. Cristoval quailed within his steel at its frailty. From a huge windlass on the platform beside him stretched three cables of four or five inches in thickness, forming the support for the narrow floor. Above and on either side was a smaller cable connected with the floor supports by ropes, and serving as guard-rails, though the security afforded was largely moral, the vertical spaces between the cords being large enough to admit of a fall through at any point. As Cristoval looked out over the quivering one hundred and fifty feet of fragility, listening to the lugubrious creaking of the cables at their anchorage, his hardihood slowly oozed. The bridge was now clear for his passage. He swore a little in undertone, piously consigned himself to the Virgin’s keeping, and led off. His horse sniffed at the footway with deep-drawn breaths and long, tremulous expirations, but followed at his word. A stiff breeze was blowing up the canyon, swinging the structure rhythmically through an arc of six or eight feet, and Cristoval’s brain reeled as he glanced at the sinister, whirling rush of green and foam bellowing a hundred feet below. Steadying his eyes on a point ahead, he picked his way out into the air. An age in crossing, but at last he neared the end. Here his weight and that of the horse shifted the sag of the cables so that the last few feet were a steep ascent with scant foothold; but he scrambled up, and with a sigh of relief, stood on solid ground. He looked back. Father Tendilla was following, leading his mule and holding his hat in place, the wind tossing and tearing at his robe, and the cavalier turned giddy again as he watched the old priest’s slow advance over the narrow, swinging floor. Cristoval gave him a hand at the end, and fairly jerked him to safety on the shelf. Pedro and the señora were to follow, and here occurred a pause. The lady balked. She seated herself on the windlass, swelling with negation. "Cross that unholy thing of strings and straws, Pedro?" she exclaimed, indignantly. "Not if I were a spider! ’T is a device of the devil, and may the devil fly away with it, or roost upon it! It is no place for a Christian. I’ll go round, and that’s an end to ’t!" "Go round!" retorted Pedro, impatiently. "Thou’lt march four hundred leagues to go around, Señora." "Then I’ll go back."
