Then they ceased speaking. The procession was still gliding along, and at the corner of the Basilica bright sparks were still appearing, flashing suddenly from out of the obscurity, as though spurting from some invisible source. The vast train of little flames, marching in double file, threw a riband of light across the darkness. But the great sight was now on the Place du Rosaire, where the head of the procession, still continuing its measured evolutions, was revolving and revolving in a circle which ever grew smaller, with a stubborn whirl which increased the dizziness of the weary pilgrims and the violence of their chants. And soon the circle formed a nucleus, the nucleus of a nebula, so to say, around which the endless riband of fire began to coil itself. And the brasier grew larger and larger--there was first a pool, then a lake of light. The whole vast Place du Rosaire changed at last into a burning ocean, rolling its little sparkling wavelets with the dizzy motion of a whirlpool that never rested. A reflection like that of dawn whitened the Basilica; while the rest of the horizon faded into deep obscurity, amidst which you only saw a few stray tapers journeying alone, like glowworms seeking their way with the help of their little lights. However, a straggling rear-guard of the procession must have climbed the Calvary height, for up there, against the sky, some moving stars could also be seen. Eventually the moment came when the last tapers appeared down below, marched round the lawns, flowed away, and were merged in the sea of flame. Thirty thousand tapers were burning there, still and ever revolving, quickening their sparkles under the vast calm heavens where the planets had grown pale. A luminous glow ascended in company with the strains of the canticle which never ceased. And the roar of voices incessantly repeating the refrain of "Ave, ave, ave Maria!" was like the very crackling of those hearts of fire which were burning away in prayers in order that souls might be saved. The candles had just been extinguished, one by one, and the night was falling again, paramount, densely black, and extremely mild, when Pierre and Marie perceived that they were still there, hand in hand, hidden away among the trees. In the dim streets of Lourdes, far off, there were now only some stray, lost pilgrims inquiring their way, in order that they might get to bed. Through the darkness there swept a rustling sound--the rustling of those who prowl and fall asleep when days of festivity draw to a close. But the young priest and the girl lingered in their nook forgetfully, never stirring, but tasting delicious happiness amidst the perfume of the invisible roses. IV THE VIGIL
