The gallery is almost entirely ruined, but a comparison with the arrangements of other monastic houses suggests that the upper storey of the western part, next to the dormitory, was the library or the writing-room. Here, where there was plenty of light, the records and accounts may have been kept. Here the books may have been copied which were used in the choir, and in the cloister and in the school. The completed records, especially such as related to the abbey lands, may have been stored in the room over the warming house, now used as a museum for fragments of pottery and broken carvings found in the ruins. This room, reached by the day stairs to the dormitory, had a bar at the door by which the occupant could lock himself in. This bar is a perplexing fact, and nobody has as yet explained why any official of the abbey should need to defend himself against intrusion in this peremptory fashion. If this was the muniment room, it held the great books of the Chartulary of Fountains, of which the volume A to C is in the British Museum. D to J is at Ripley Castle, and K to M is in the library of the late Sir Thomas Phillips. The remaining volumes are not yet traced. Here were kept the bundles of title-deeds, now at Studley Hall; with pendant seals, which show that there were neighbouring farmers who attested their signatures with impressions of Roman gems which their forefathers had turned up with the plough. The President Book would be kept here, with its dated list of abbots up to 1471; and the Coucher Book, with its register of the dealings of the monks with their manors. These two probably lay by the abbot’s side as he sat in his place in the chapter house at business meetings. They are now preserved in the muniment room at Studley Hall. The long corridor, which connected the cloister with the infirmary, passed, as we have seen, the abbot’s lodging on the right and the entrance-way to the chapel of the nine altars on the left. Opposite the chapel entrance there was an opening into the coal-yard. Coal was found here when the recent excavations were made. In the south-east corner of this yard lay the abbey rubbish heap, the materials of which were apparently shovelled out from the window beside it, whose sill shows the marks of this daily exercise. Here were found various broken dishes, a sickle blade, a copper can, bushels of oyster shells, and bones identified as belonging to beef, mutton, pork and venison, together with a great quantity of ashes. The room out of which this refuse was thrown is reached by a passage which opens out of the long corridor close by the infirmary door. Here, according to Mr. Walbran, stood the reservoir, fed by a lead pipe from a spring on the high bank.
