A French manuscript chart of Halifax harbour in Nova Scotia on eighteenth century French paper watermarked ‘I. Martin Poitou’. The naval base of Halifax was founded in 1749 by the British following the capture of Nova Scotia in the Seven Years War. It was attractive as an ice-free deep-water harbour and counter to the French fort at Louisbourg. The harbour was first surveyed by Charles Morris whose work was published by Thomas Jefferys in 1759. This manuscript may well be derived from it however there are notable differences. Whilst it does show the fort at Halifax it also records depth soundings in Bedford Basin which were not present on the printed chart. They do appear on Jacques Nicolas Bellin’s chart of the area published in 1764, but again significant differences occur. It is highly probable that this manuscript might have been produced in Canada.
