Dennis Grenville was equal to the trying occasion. He found that the Church services were often either curtailed or omitted altogether; many of the churches were 'altogether unprovided of ministers'; and the fabrics themselves were 'ruinous and in great decay.' Not only the minor Canons and singing men, but even many of the highest dignitaries were guilty, according to Cosin,[37] of sluttish and disorderly habits, even in the cathedrals themselves; and the Rubrics and Canons were almost ignored. But, as Parish Priest, as Prebendary, and as Archdeacon, and afterwards, especially in securing a weekly celebration of the Holy Communion in his own cathedral, Dennis Grenville laboured so earnestly and so conscientiously, as to warrant his promotion, young as he was, to the post of Dean. His rapid advancement, however, seems to have almost turned his head; he became ambitious and extravagant, was frequently absent from his post, and fell into pecuniary troubles (aggravated by the non-payment of an expected marriage portion with his wife) which, almost to the last, hung like a millstone round his neck. On the 8th of July, 1674, on returning from public prayers and Captain Foster's funeral, he was actually arrested 'in his Hood and Surplice' for debt, within the cloisters; and although he was afterwards released as a Chaplain in Ordinary of the King, and though the bailiffs and the Under Sheriff who were responsible for his arrest were reprimanded before the Council Board at Hampton Court, yet the indignity seems to have entered into the Dean's very soul, producing, however, more than one good result, viz. the more economical management of his resources, and salutary counsels to his nephew at Oxford, published in 1685. He was a capital preacher, but a bad man of business: '"I cannot manage nor mind these money affairs," is his own candid confession,' observes the Rev. George Ormsby, in his interesting memoir. Of the Dean's management of his own household full details are preserved; they will probably be found interesting here as showing how a Church dignitary lived two hundred years ago: one who was always at work on the scheme of reformation to which he had laid his hands, and who seems to have taken for his model George Herbert's 'Country Parson.' This book he recommended to his curates, and to all the clergy in his jurisdiction, 'for their rule and direction in order to the exemplary discharge of their functions, having always made it mine.' The Diocese of Durham, under such auspices as those of Cosin and Grenville, (notwithstanding the incapacity of the latter to properly manage his money affairs,) accordingly improved rapidly in tone, until the Dean was at length able to report to the King that it was 'without dispute the most exemplary county for good order and conformity of any in the nation.' These, then, were amongst Dean Grenville's thirty-two Home Rules:
