sleep that partook more of the character of a nightmare than of Nature's sweet restorer.
Meanwhile his wife had for some time made a show of sleeping. But she watched her husband anxiously. When she felt certain that he had at length succumbed to a deep sleep, she softly rose, and scarcely daring to breathe, crept out into the kitchen. She opened the window gently and looked out.
The night was dark; now and again vivid flashes of lightning lit up the sky. No sound was heard save the roar of the rushing currents of the Tagus, and the sighing of the wind as it swept in and out among the scaffolding and complicated framework of the bridge.
Catherine noiselessly closed the window. From the hearth she took one of the half-burnt faggots which still smouldered, and throwing a cloak over her shoulders went out into the silent streets, her heart beating wildly.
Where was she proceeding? Was she carrying that burning faggot as a torch to light her path in the dense darkness of a moonless night? It was indeed a dangerous track, covered as it was with broken boulders, and uneven ground. Yet she strove rather to conceal the lighted wood beneath her cloak.
At last she reached the bridge. The wind still sighed and whistled, and the river continued to break its current against the pillars, as though irritated at meeting obstacles which it could no longer sweep away.
Catherine approached the buttress of the bridge. An involuntary shudder of terror passed through her frame. Was it because she stood on the edge of that abyss of roaring waters? Or was it because her hand, only accustomed hitherto to deeds of goodness, was now brandishing the torch of destruction? Or rather did she tremble because a tremendous peal of thunder at that moment resounded through the vault of heaven.
Waving the torch to kindle it afresh, she applied it to the dry, resinous wood of the scaffolding. The wood quickly ignited, and the flame, fanned by the wind, ascended with fearful rapidity, spreading and involving arches and framework and the whole structure of the bridge.
"The flame ascended with fearful rapidity."
Then she quitted the scene swiftly. Aided by the glare of the conflagration and the vivid flashes of lightning which lit up the sky, Cath- erine soon traversed the space which separated her from her home. She entered as noiselessly she had left it, and closed the door. Her husband still slept soundly, and had not missed her. Catherine again pretended to be fast asleep, as though she had never left her bed.
