Firstly, then, a beam runs transversely and horizontally across from pillar to pillar of the chancel arch, or in front thereof, sometimes supported by corbels at either end, as has been the case at _Heckington_ and _Wellingore_. This may or may not be the rood-beam (_i.e._ the beam on which the rood stood). In some cases the rood-beam was quite separate from and independent of the screen, as at _Claypole_, where there are corbels for it on each side of and high up on the chancel arch; at _Legbourne_, where the same arrangement is made, and in the _Morning Chapel, Lincoln Minster_. At _Blyton_ the rood-beam remains above the chancel arch; above the upper side of the beam the wall is recessed, probably to allow of a boarded and panelled background to the rood and the other two figures. Further support to this beam (of the screen) is afforded by a number of stout uprights from the floor (where is sometimes a horizontal wooden or a stone base) to the rood-beam, dividing the screen into bays, varying in number with the size of the screen, whereof the middle one is generally the largest, though at _Frampton_, _Stixwould_, _Mumby_, _Middle Rasen_, _Lusby_, and _Miningsby_ it is of the same size as the others. The middle bay is as 13 to 11, for example, at _Cotes_, as 2 to 1 at _East Kirkby_, as nearly 5 to 4 at _Moulton_, as 3½ to 2 at _Bratoft_, and as 3 to 2 at _Thorpe St. Peter’s_. These uprights are often formed into small pillars in the front, and occasionally on the eastward aspect also, or, in more Perpendicular work, they are fashioned as slender buttresses, _Cotes_ and _Sleaford_ giving examples of the former, while _East Kirkby_ does so of the latter method. From these uprights, at about two-thirds of their height, spring more or less pointed arches, with their apices at the beam or just below it. Generally, the lower third of the screen is composed of solid panelling, sunk and with foliated and traceried heads; though at _Barrow-on-Humber_, at _Spalding_, and at _Alford_ the panels are perforated, probably this is not original. Along the upper border of these panels often runs a scroll or vignette of open work, as at _Winthorpe_ and at _East Kirkby_, and of Tudor flowers at _Croft_, while it is embattled at _Westborough_ and _Yarburgh_.
