In the floor are slabs bearing the names of Chancellor Reynolds (d. 1766) and of Precentor Trimnell (d. 1756), the "chanter" who was accused of removing the statues over the central doorway outside. On the wall at the north-east corner is a tablet to the memory of the officers, non-commissioned officers, and privates of the 10th or North Lincolnshire regiment of infantry, who died in the campaigns of the Sutlej (1845-46) and of the Panjab (1848-49); the tablet was erected by their surviving comrades. The compartments under the western towers were vaulted by Treasurer Welburne (ab. 1350-80), to whom is also due the tracery which covers the walls. The curious chambers constructed in the thickness of the old Norman west front are accessible from the sills of the western windows, these being joined by narrow passages in the wall. On the north side we are able in the same way to reach a long narrow chamber, which probably served as a treasury, constructed in the north wall of the tower. The chamber was originally lighted by four small round-headed windows. One of them, on the west side, is still open; the two facing northwards, formerly outside windows, are now enclosed by the northwest chapel, and blocked up; the fourth, on the east, is also blocked. A square hole in the floor formed at one time the only means of access to the chamber beneath, which may now be reached by a doorway from the porch. In the north wall of this lower chamber is a low semi-circular arch, supposed to have been constructed by the Norman builders, in order to avoid some obstacle in the way of the foundations. This arch was filled in with masonry, now pierced by a doorway. The north-west chapel, which is entered by this doorway, encloses the outer wall of St. Mary's tower. [Illustration: Half Section of the Nave, looking West.] The corresponding chapel on the south side of the minster is sometimes called the "Ringers' Chapel." On its walls is painted a seventeenth century list of the "Names of the Companie of Ringers of our Blessed Virgen Marie of Lincolne." In one place we see "Edward Whipp 1617 at the kings coming to Lincolne." This refers to the visit of King James I. in March of that year, when he visited the minster, and touched a number of persons for the evil. His Majesty went also to a cock-fight at an inn near the Stone-bow, and to a horse-race on the Heath. Edward Whipp was evidently one of those who rang the bells in honour of the royal visit. The Ringers' Chapel encloses part of the south wall of St. Hugh's tower, which has a large arched recess and a niche, similar to those in the west front.
