The organ is placed in a position differing from that of most others in England, although not unusual in Continental Cathedrals. The pedal and swell organs have been placed in the triforium on the north side, and the great organ, with the choir organ beneath it, project in front of the third bay, resting upon an over-hanging chamber behind the stalls. The organ was reconstructed, with great additions, by Messrs. Hill and Son, of London, when the removal took place in 1851, and several important additions were made in 1867, by the same firm.[39] The magnificent organ-case, with its sculptures, was executed by Mr. Rattee; the pipes in front have been gilded and ornamented by Mr. Castell, of London, and much of the woodwork having been left in its natural colour forms an agreeable contrast, and the effect produced, from almost every point of view, is rich and beautiful; while from its unusual position it loses little of its power or sweetness of tone, but sends forth its pealing sounds reverberating through the lofty arches with fine effect. We know nothing more sublime than the voices of a congregation, guided and supported by such an instrument, praising and adoring the great Creator and Father of all, and are led to exclaim with the poet Milton-- "There let the pealing organ blow, To the full voiced choir below, In service high and anthems clear, As may with sweetness through mine ear, Dissolve me into ecstacies, And bring all heaven before mine eyes." [Footnote 39: See Appendix I.] The division between the Early English work of Bishop Northwold and that part generally spoken of as Hotham's work is marked by two steps in the floor, and by two strong piers rising from the floor to the vault, which were in fact the original Norman shafts near the commencement of the apse or east end taken down by Hugh de Northwold, eighth bishop, who added the six beautiful eastern bays at his own expense; these form a pure and good example of Early English work, and were completed A.D. 1252, and dedicated in the same year, in the presence of King Henry III., and many nobles and prelates. This was called the "Presbytery," or "Sanctuary," a common name at that time for the east end of a church.
