Work is proceeding to repair the fame of the lantern and the
window panels.  Rotten wood is being removed and the remaining sound
wood either filled or a new piece of wood scarfed in.  Only as a last
resort is a complete member being replaced.  Where necessary the joints
of each panel are being re-glued.  A crucial part of the lantern, the
sill around the base, is extensively rotted and is being replaced with a
new sill shaped to the same section as the original sill.
