Task: Question Generation
Input (English):  The Last Chronicle of Barset concerns an indigent but learned clergyman, the Reverend Josiah Crawley, the perpetual curate of Hogglestock, who stands accused of stealing a cheque.
The novel is notable for the non-resolution of a plot continued from the previous novel in the series, The Small House at Allington, involving Lily Dale and Johnny Eames. Its main storyline features the courtship of the Rev. Mr Crawley's daughter, Grace, and Major Henry Grantly, son of the wealthy Archdeacon Grantly. The Archdeacon, although allowing that Grace is a lady, doesn't think her of high enough rank or wealth for his widowed son; his position is strengthened by the Reverend Mr Crawley's apparent crime. Almost broken by poverty and trouble, the Reverend Mr Crawley hardly knows himself if he is guilty or not; fortunately, the mystery is resolved just as Major Grantly's determination and Grace Crawley's own merit force the Archdeacon to overcome his prejudice against her as a daughter-in-law. As with Lucy Robarts in Framley Parsonage, the objecting parent finally invites the young lady into the family; this new connection also inspires the Dean and Archdeacon to find a new, more prosperous, post for Grace's impoverished father.
Through death or marriage, this final volume manages to tie up more than one thread from the beginning of the series. One subplot deals with the death of Mrs. Proudie, the virago wife of the Bishop of Barchester, and his subsequent grief and collapse. Mrs. Proudie, upon her arrival in Barchester in Barchester Towers, had increased the tribulations of the gentle Mr. Harding, title character of The Warden; he dies of a peaceful old age, mourned by his family and the old men he loved and looked after as Warden.
Output (English): What did Mr Hardng died of?
