This key research resource is an important survival, being a manuscript account book detailing transactions - debits and credits - relating to the lead-ore company at Leadhills, operated by Sir John Hope of Craighall. Many important people are mentioned in this book, including Alexander Hope of London, Archibald Hope of Craighall, the Earl of Wigtown, the Duke of Hamilton, the Lord of Inglestone, Charles Erskine of Alba, Alexander Tait, Lady Marie Keith, the Earl of Crawford, Lord Mordington, Lord Cardcross, and Alexander Ross. The amounts involved are huge, with the account of revenues in hand running to over £70,000 towards the end of the period.
