The cellars of the Champagne manufacturers are very varied in character. The wine that has been grown on the chalky hills is left to develop itself in vaults burrowed out of the calcareous strata which underlie the entire district. In excavating these cellars the sides and roofs are frequently worked smooth and regular as finished masonry. The larger ones are composed of a number of spacious and lofty galleries, sometimes parallel with each other, but often ramifying in various directions, and evidently constructed on no definite plan. They are of one, two, and, in rare instances, of three stories, and now and then consist of a series of parallel galleries communicating with each other, lined with masonry, and with their stone walls and vaulted roofs resembling the crypt of some conventual building. Others of ancient date are less regular in their form, being merely so many narrow, low, winding corridors, varied, perhaps, by recesses hewn roughly out of the chalk, and resembling the brigands' cave of melodrama; while a certain number of the larger cellars at Reims are simply abandoned quarries, the broad and lofty arches of which are suggestive of the nave and aisles of some Gothic church. In these varied vaults, lighted by solitary lamps in front of metal reflectors, or by the flickering tallow candles which we carry in our hands, we pass rows of casks filled with last year's vintage or reserved wine of former years, and piles after piles of bottles of _vin brut_ in seemingly endless sequence--squares, so to speak, of raw recruits for the historically famous 'Regiment de Champagne'[417]--awaiting their turn to be thoroughly drilled and disciplined. These are varied by bottles reposing neck downwards in racks at different degrees of inclination, according to the progress their education has attained. Reports caused by exploding bottles now and then assail the ear, and as the echo dies away it becomes mingled with the rush of the escaping wine, cascading down the pile, and finding its way across the sloping sides of the floor to the narrow gutter in the centre. The dampness of the floor and the shattered fragments of glass strewn about show the frequency of this kind of accident. [Illustration: DETACHING THE 'MASK' FROM THE SIDES OF THE BOTTLES.]
