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 Saint Marceaux and Co.’s new and capacious establishment is installed. The principal block of building is flanked by two advanced wings inclosing a garden-court, set off with flowers and shrubs, and from the centre of which rises a circular shaft, covered in with glass, 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 hundreds of casks replete with the choice _crûs_ of Verzenay, Ay, Cramant, and Bouzy, while some thousands of bottles ready for labelling are stocked 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 to Hong-Kong, San Francisco, Yokohama, Bombay, London, New York, St. Petersburg, Berlin, or Paris. The wine in cask, stored in the left-hand wing, after having been duly blended in a vast vat holding over 2,400 gallons, 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 prevent 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 descend 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 find no less than four-and-twenty galleries excavated in the chalk, without any masonry supports, and containing upwards of a million bottles of champagne. The length of these galleries varies, but they are of a uniform breadth, allowing either a couple of racks with wine _sur pointe_, or stacks of bottles, in four rows on either side, with an ample passage 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_.
