"Licence for William de Stirkeland, to whom the king lately granted licence to crenellate with stone and lime a chamber in Penreth upon the March of Scotland, to make a mantlet of stone and lime, join it to the said chamber and crenellate the same and so hold it for ever, in aid and succour of the said town and adjacent country.
The roll recites the previous grant thus: "nuper," &c., "concessimus," &c., "licentiam," &c., "kernellandi quandam cameram in villa de Penreth March. Scociae. Nos de uberiori gratia nostra concessimus" &c., "licentiam quod ipse unum mantelettum de petra et calce facere et camerae prasdictae conjungere et mantelettum praedictam kernellare," &c."
Granted at Westminster, by privy seal.
