The old château of Ay, which dates from the early part of the last century, belongs to-day to the Count de Mareuil, a member of the firm of Ayala and Co., one of the leading establishments of the famous Marne-side crû. Perched half-way up the slope, covered with “golden plants,” which rises in the rear of the village, the château, with its long façade of windows, commands the valley of the Marne for miles, and from the stately terraced walk, planted with ancient lime-trees, geometrically clipped in the fashion of the last century, a splendid view of the distant vineyards of Avize, Cramant, Epernay, and Chouilly is obtained. The château formed one of a quartette of seignorial residences which at the commencement of the present century belonged to Balthazar Constance Dangé-Dorçay, whose ancestors had been lords of Chouilly under the _ancien régime_. Dorçay had inherited from an aunt the châteaux of Ay, Mareuil, Boursault, and Chouilly, together with a large patrimony in land and money; but a mania for gambling brought him to utter ruin, and he dispossessed himself of money, lands, and châteaux in succession, and was reduced, in his old age, to earn a meagre pittance as a violin-player at the Paris Opera House. The old château of Boursault, which still exists contiguous to the stately edifice raised by Mme. Clicquot on the summit of the hill, was risked and lost on a single game at cards by this pertinacious gamester, whose pressing pecuniary difficulties compelled him to sell the remaining châteaux one by one. That of Ay was purchased by M. Froc de la Boulaye, and by him bequeathed to his cousin the Count de Mareuil, whose granddaughter became the wife of one of the Messrs. Ayala, and whose son is to-day their partner. [Illustration: MESSRS. AYALA & CO.’S ESTABLISHMENT AT AY. (p. 121)]
