But at the close there was a procession which is worth considerable description. Six men with censers of silver lined up before the high altar, and stood there, slowly swinging the fragrant bowls at the end of their long chains. The music died down. One could hear the rhythmical, faint clangour of the metal. And then, intensely sudden, away in the west gallery, but almost as if from the battlements of heaven, pealed out silver trumpets in a fanfare. The censers flew high in time with it, and the sweet clouds of smoke, caught by the coloured sunlight of the rich painted windows, unfolded in the air of the sanctuary. Lights moved and danced, and the space before the altar filled with the white of the men and boys who should move in the procession. Again and again those trumpets rang out, and hardly had the last echoes died away than the organ thundered the _Pange Lingua_, as a priest in cloth of gold turned from the altar with the glittering monstrance in his hand. Even from where he stood Peter could see the white centre of the Host for Whom all this was enacted. Then the canopy, borne by four French laymen in frock-coats and white gloves, hid It from his sight; and the high gold cross, and its attendant tapers, swung round a great buttress into view. Peter had never heard a hymn sung so before. First the organ would peal alone; then the men's voices unaided would take up the refrain; then the organ again; then the clear treble of the boys; then, like waves breaking on immemorial cliffs, organ, trumpets, boys, men, and congregation would thunder out together till the blood raced in his veins and his eyes were too dim to see. Down the central aisle at last they came, and Peter knelt with the rest. He saw how the boys went before throwing flowers; how in pairs, as the censers were recharged, the thurifers walked backward before the three beneath the canopy, of whom one, white-haired and old, bore That in the monstrance which all adored. In music and light and colour and scent the Host went by, as It had gone for centuries in that ancient place, and Peter knew, all bewildered as he was, there, by the side of the girl, that a new vista was opening before his eyes.
