Por geographical details of coastlines, islands, soundings for navigation, and similar data, this diary and accompanying documents resulting from a survey voyage by Ensign Chabert from Brest to the region between Acadia and Newfoundland is outstanding. This fact undoubtedly explains its republication after two hundred and thirteen years. As the diarist constantly explains in his narrative, previous maps and charts were very erroneous, often causing maritime disasters. Because of the extreme competition of the mid-century, soon to break into open war between Great Britain and France for control of this area and the rest of North America, one can readily understand why the French king ordered the survey to be made close to the great fortress at Louisburg. The volume is an excellent example of réimpression.
