At _Claypole_ and _Althorpe_ the central shaft is carried down much below the spring of the ogees, and ends on a four-centred arch. _East Kirkby_ has two ogees on an ogival arch beneath. At _Saxilby_ the central feature takes the form of a round-headed arch in a square-headed bay with the spandrils filled with circles, surmounted by seven small bays, each containing a crocketed ogee terminating in a finial. At _Barrow_ there is a pointed arch, with pierced spandrils. At _Benniworth_ there is a large ogee with curious tracery over it (? modern), entirely different from the lateral bays. At _Ewerby_, already mentioned, this bay has on the inner side of each ogee a beautiful wheel; on the outer side a fine network of tracery. At _Folkingham_ the centre arch is carved and crocketed with grapes and vine-leaf ornament. At _Scrivelsby_, between two ogees is a large wheel of tracery, with two smaller ones filling in the spaces on each side. All screens probably had a door or doors, though but few of these are left in Lincolnshire. At _Westborough_ the original doors exist; they are square-headed, with tracery above and panelling below, similar to that of the side bays. _Cotes_, _Spalding_, _Theddlethorpe_, _East Kirkby_, _Moulton_, _Helpringham_, _Thorpe St. Peter’s_, and _Barton_ still retain their doors, but only the lower panels are left. Also slender buttresses have been mentioned above, as being moulded out of the uprights. Occasionally there were to the front (western face) of these uprights, especially on each side of the central doorway, flying buttresses with crocketed attachments. Remains of these are still to be seen at _East Kirkby_, _Moulton_, _Fishtoft_, _Thorpe St. Peter’s_, _Bratoft_, _Croft_, _Legbourne_, _Crowland_, and _Mumby_. At _Grimoldby_, where the lower half of the screen exists, two buttresses project some way westward and are well panelled. The extreme form of these, where the upright part of the buttresses was fashioned into a candlestand, may be exemplified by Ranworth screen (Norfolk), where the buttresses, panelled as to their lower two-thirds, separate the central passage from an altar on either side. The intervening spaces between the ogee and the confining arch will be filled in with delicate tracery, varying of course in style with the age and locality of each particular screen. Whatever the faults of Perpendicular work may be in stone, the repetition of similar forms, the richness of the detailed ornament, and the lightness of the tracery make Perpendicular _wooden_ screens, more perhaps than any others, the best representatives of the _Cancelli_ (lattice-work), and very valuable portions of the furniture of a church. In some churches, as at Laughton-en-le-Morthen, there was a low _stone_ screen, buttressed, which would carry a lighter screen of wood. Instances of a similar arrangement may be seen at Nantwich and _Morton-by-Bourne_, and there is a preparation for it at _Wellingore_ and _Boston_.
