The beautiful groined roof of the chapter-house was intact until the end of the last century. Beyond the chapter-house was the fratry, or monks' common room, which was 200 feet long, and over it were the dormitories. Near the western tower the walls of the hospitium, or guest-house, may still be traced. At the south end of the ruins there is a building with a groined room which has generally been called the school-house, but many authorities now consider that it was a small chapel, as it contains a large east window and a piscina; if this be so, then it was without doubt the Abbot's private chapel. The date assigned to it is early in the fourteenth century. Near to the abbey the Preston family, to whom the site was granted soon after the dissolution,[179] built their mansion, and part of this house now forms the Furness Abbey Hotel. In 26 Henry VIII. the rentals belonging to the abbey amounted to £942 per annum, of which tithe offerings and ecclesiastical fines came to £182. In 1540 these possessions were annexed to the Duchy of Lancaster, and were not finally alienated therefrom until the time of James I. From the Prestons it passed by marriage to Sir William Lowther, Bart., whose son and heir married Lady Elizabeth, the daughter of William, Duke of Devonshire; his son and heir, dying without issue in 1756, bequeathed all his estates to his cousin, Lord George Augustus Cavendish. The coucher book of Furness is still preserved in London; it is a handsome volume containing 293 folios. On the seizure of the abbey in 1537 this volume and other memorials, trussed in three packs, were sent by Cromwell on the back of three mules to London, and £1 15s. 4d. was expended on their conveyance. It was afterwards placed in the duchy office, and ultimately handed over to the Record Office.[180]
