Note 835 — Chapter IV · TUTORS AND GOVERNORS 1221–1223
Reading edition
“Treugas ... quas coepit, ut praedictis significavit, ut interim in partibus Lincolniae sua possit usitare et expendere.” Roy. Lett., vol. i. p. 172. There seems to be a noun omitted in connexion with “sua”; I think the meaning of the sentence must be as I have rendered it.
