So they chatted on. But what was it that Nan, who had accompanied them, had heard as she sat in the great, empty, dimly-lit Cathedral, with her hands clasped, her head bent forward on them, her eyes closed? Or, rather, what was it that she saw?--for this seemed to be a picture in music. She saw a small chapel far away up in the mountains, the trembling red rays in the windows looking strange above the snow. She heard the monks at their midnight chanting--low, and sad, and distant. And then it seemed, as she listened, as if the stars overhead were being blurred out, and a murmuring wind came down the gorge, and the air grew cold. The darkness deepened; the wind rose and moaned through the pine forests; then an angry gust swept along, so that the intoning of the monks was lost altogether. There was a rumble of distant thunder--overhead, among the unseen peaks. But still, unconscious of the threatening storm, those within the small building went on with their holy office, and there were snatches of the clear singing of boys--so faint that you could scarcely hear; and again the strong, sad, sombre voices of the men. Then the tempest broke, fierce and terrible: the elements seemed mingled together. She lost sight of the chapel in the whirling snow; the heavens rattled overhead; and the wind swept down so that the whole earth trembled. A horror of wrath and darkness has overwhelmed the world; and what of the patient choristers now? No longer are their voices heard amid the appalling fury of the hurricane; the sudden lightning-flash reveals nothing in the blackness; the powers of evil have overcome; and the universe has lost its hope. But now there comes a lull; and suddenly--far away, and faint, and triumphant--rises the song of reliance and joy. The demons of the night mutter and moan; but the divine song rises clearer and more clear. It is the voice of faith, silver-toned and sweet; and the very heavens themselves seem to listen; and the thunders rumble away into the valleys; and the stars, shining, and calm, and benignant, come out again over the mountain-peaks. And lo! once more she can descry the faint red rays above the snow; and she can almost see the choristers within the little building; and she listens to the silver-clear song; and her heart is filled with a strange new gladness and trust. What must she do to keep it there for ever? By what signal self-sacrifice--by what devotion of a whole life-time--by what patient and continuous duty--shall she secure to herself this divine peace, so that the storms and terrors and trials of the world may sweep by it powerless and unregarded?
