Lady Catherine de Bourgh's attention to his wishes, and consideration for his comfort, appeared very remarkable. Mr. Bennet could not have chosen better. Mr. Collins was eloquent in her praise. The subject elevated him to more than usual solemnity of manner, and with a most important aspect he protested that \"he had never in his life witnessed such behaviour in a person of rank--such affability and condescension, as he had himself experienced from Lady Catherine. She had been graciously pleased to approve of both of the discourses which he had already had the honour of preaching before her. She had also asked him twice to dine at Rosings, and had sent for him only the Saturday before, to make up her pool of quadrille in the evening. Lady Catherine was reckoned proud by many people he knew, but _he_ had never seen anything but affability in her. She had always spoken to him as she would to any other gentleman; she made not the smallest objection to his joining in the society of the neighbourhood nor to his leaving the parish occasionally for a week or two, to visit his relations. She had even condescended to advise him to marry as soon as he could, provided he chose with discretion; and had once paid him a visit in his humble parsonage, where she had perfectly approved all the alterations he had been making, and had even vouchsafed to suggest some herself--some shelves in the closet up stairs.\""), + GERMAN(Locale.GERMANY, "Aber dieser Freiheit setzte endlich der Winter ein Ziel.
