The extensive cellier, the area of which is 23,589 square feet, is understood to be the largest single construction of the kind in the Champagne district. Built entirely of iron, stone, and brick, its framework is a perfect marvel of lightness. The roof, consisting of rows of brick arches, is covered above with a layer of Portland cement, in order to keep it cool in summer and protect it against the winter cold, two most desirable objects in connection with the manipulation of Champagne. Here an endless chain of a new pattern enables wine in bottle to be lowered and raised with great rapidity to or from the cellars beneath--lofty and capacious excavations of two stories, the lower one of which is reached by a flight of no less than 170 steps. [Illustration: COURTYARD OF MESSRS. POL ROGER AND CO.'S ESTABLISHMENT AT EPERNAY.] Less than a couple of miles southward of Epernay, on the high-road to Troyes, is the village of Pierry, which, unlike most of the Champagne villages, is one of those happy spots with little or no history. Up to the close of the seventeenth century it was an insignificant hamlet; but at that epoch--when Dom Perignon's discovery gave such an impetus to the viticultural industry of the Marne--the waste land lying around it was broken up and planted with vines, and a number of rich strangers, chiefly from Epernay, built themselves houses and vendangeoirs here, and contributed to the erection of the church. The Benedictines of St.-Pierre-aux-Monts at Châlons, who continued to be the titular seigneurs of Pierry up to the period of the Revolution, were not behindhand in attention to their vines, and during the early part of the eighteenth century the wine vintaged in their Clos St. Pierre, under the fostering care of Brother Jean Oudart--whose renown almost equalled that of Perignon himself--was very highly esteemed.[449] During the eighteenth century Pierry continued to be a favourite residence of well-to-do landowners,[450] and was further embellished by the construction of numerous handsome châteaux, the most interesting, from a historic point of view, being that formerly belonging to Cazotte.[451] It was here that the ex-Commissary General of the navy composed the greater part of his works, and elaborated that futile scheme for the escape of Louis XVI. after Varennes, which was to conduct its author to the scaffold.[452] The visionary dreamer, to whom we owe the _Diable Amoureux_, appears at Pierry in the triple character of a practical viticulturist, a village Hampden withstanding with dauntless breast that little tyrant of the surrounding vineyards--the Abbot of Hautvillers,[453] and a local legislator put forward in the proprietarial interest at the outbreak of that Revolution[454] which he appears to have foreseen, if not to have directly prophesied, as he has been credited with doing.[455]
