On leaving Messrs. Pommery's we retrace our steps down the Avenue Gerbert, bordered on either side with rows of plane-trees, until we reach the treeless Avenue de Sillery, where Messrs. de St. Marceaux & Co.'s new and capacious establishment is installed. Simple and without pretension, the establishment, which covers an area of upwards of 18,000 feet, is distinguished for its perfect appropriateness to the industry for which it was designed. The principal block of building is flanked by two advanced wings enclosing a garden-court, set off with flowers and shrubs, and from the centre of which rises a circular shaft, covered in with glass, and admitting light and air to the cellars below. In the building to the left the wine is received on its arrival from the vineyard, and here are ranged large quantities of casks replete with the choice crus of Verzenay, Ay, Cramant, and Bouzy, while thousands of bottles ready for labelling are stacked in massive piles at the end of the packing-hall in the corresponding wing of the establishment. Here, too, a tribe of workpeople are arraying the bottles with gold and silver headdresses, and robing them in pink paper, while others are filling, securing, marking, and addressing the cases or baskets destined to Hong-Kong, San Francisco, Yokohama, Bombay, London, New York, St. Petersburg, Berlin, or Paris. [Illustration: THE PACKING-HALL OF MESSRS. DE ST. MARCEAUX AT REIMS.] The wine in cask, stored in the left-hand wing, after having been duly blended in an enormous vat, is drawn off into bottles, which are then lowered down a shaft to the second tier of cellars by means of an endless chain, on to which the baskets of bottles are swiftly hooked. The workman engaged in this duty, in order to guard against his falling down the shaft, has a leather belt strapped round his waist, by means of which he is secured to an adjoining iron column. We descended into the lower cellars down a flight of ninety-three broad steps--a depth equal to the height of an ordinary six-storied house--and found no less than four-and-twenty galleries excavated in the chalk, devoid of masonry supports, and containing upwards of a million bottles of Champagne. These galleries vary in length, but are of uniform breadth, and allow either for a couple of racks with wine _sur pointe_, or stacks of bottles, in four row's on either side, with ample passage-room down the centre. The upper range of cellars comprises two large arched galleries of considerable breadth, one of which contains wine in wood and wine _sur pointe_, while the other is stocked with bottles of wine heads downward, ready to be delivered into the hands of the _dégorgeur_.
