After two or three hours spent in visiting the various departments of the glassworks overhead, M. Henrivaux led me through winding passages, which reminded me of the dismal vomitories at Baiae, down into this strange underworld. Walls and pillars, partly of the natural rock, left in the working of the quarries, partly of masonry built up to strengthen the reservoir, give this weird water, when you reach it, the aspect rather of a stream than of a lake. A workman, who had preceded and guided us with a swinging lantern, put out a long boathook, and drew slowly around to the landing-place a long, shallow boat, into which he invited us to step. M. Henrivaux had kindly sent orders in the morning to have the reservoir illuminated with Venetian and Chinese lanterns of various colours. These had been hung from hooks in the rocks and pillars with infinite good taste at long intervals, so as to illuminate not too brilliantly the mystical darkness of the scene. Looking upon the vague, indefinite vista, as it glimmered away into an indefinable distance, one seemed really to stand Where Alp, the sacred river, ran Through caverns measureless by man, Down to a shoreless sea. Seating ourselves carefully in the boat, our silent boatman, like a spectral gondolier, rowed us silently along the labyrinthine canals of this dim and ghostly Venice. Vathek Beckford would have made them waterways to the Hall of Eblis. CHAPTER VIII IN THE AISNE--_continued_ LAON The lively little city of Chauny, standing in the heart of the rich and lovely valley of the Oise, the 'golden vale' of this part of France, has a history of its own of which I shall presently have something to say, and which throws some interesting light upon the general history of France. But Chauny owes its actual prosperity mainly to its connection with the Company of St.-Gobain. From a very early period in the annals of the company, the plate-glass made at St.-Gobain was sent across the country to Chauny, and thence by water to Paris, where it was polished and 'tinned' at the company's works in the Rue de Reuilly.
