A word or two must suffice to describe the side screens of the choir, which separate it from the north and south choir aisles. Very probably, in addition to other uses, these screen-walls were built to connect together the piers of the choir arcades, at least in the three western bays, and so help to take off some of the thrust produced by the central tower, and were constructed after its fall. The north screen-wall has an arcade or triple shafts, ornamented with dog-tooth, and with twisted bosses like the rounded head of a drill or a coil of rope at the springing of the arches. The fourth bay eastwards is of later date, the capitals much under-cut, and the corbels at the apex of the string-course having birds among natural foliage. The fourth bay on the south side is very similar; the next has later work inserted again, for the shrine of Little St. Hugh, the second bay being like the northern three, and the first taken up with the staircase for the constable of the close, and a square grated window lighting the room in the organ-loft, already described. Only those who have seen the magnificent sculptured work on the side screens of the choir of Chartres, Amiens, and Notre Dame can appreciate what _can_ be done in decorating these screens. The last stone screen to be described is in _Tattershall Collegiate Church_, founded in 1439 by Ralph, Lord Cromwell, Lord Treasurer of England. The pulpitum, or choir screen, is of stone, and is situated between the eastern piers of the crossing. It is approached by a broad stone step, wider at the southern than at the northern end. It is a solid screen-wall with a central passage, having on the north side a staircase leading to the loft above, and on the south side a door to a small room (in the same position as in the _Lincoln Minster_ screen), lit by three quatrefoils into the nave. The western face of the screen consists of three recesses, with wide ogee-headed arches, cusped internally, and ending in finials which run straight up to the cornice of the loft and are there cut off. There is a string-course at the apex of the arches; the intervening spaces are filled with shallow panels, having arched and cusped heads. The northern and southern ends of the screen are chamfered off, and there are traces of some pedestal and tabernacle work in the broken stonework about the height of the string-course, and again below the spring of the arches. The whole of this west front is finished off with a cresting of Tudor flowers. The central doorway takes up one of the recesses, the oak doors being mainly original, though great hooks for hinges still exist in the stonework behind them. The other two recesses exhibit very evident manifestations of having once contained altars, there being small pillar piscinæ in the south side of each recess, and marks of where the altar slabs were fitted to the work behind. They were in the same position as those at Bishop Le Hart’s screen at Norwich, at the beautiful screen in
