The map includes numerous notations giving the reader some historical and environmental context. Examples of these are: "The climate of this land is a great deal more temperate than Hudsons Bay" for an area in western Ontario north of the Lake of the Woods and "Christian Sea discovered by Jn Monk in 1619" on Baffin Bay.
According to Skelton & Tooley (#13) the imprint is indicative of the 1st state of the North American Pilot. While several maps in the North American Pilot were previously published, the Chaleur Bay map was not. Notes underwater features and fishing banks.
Includes inset "The Entrance of the River St. John". The elliptical cartouche includes the following text and is typical of DesBarres' navigational notes when present: "The River St. John, has sufficient depth of Water for large Ships to the Falls. Whence it continues Navigable 80 miles up into the Country of Vessels of 100 Tons. At Fort Frederick, common Tides rise 18 feet perpendicular, and Equinoctial Spring Tides 25 Feet, above the Falls, it seldom flows more than 4 Feet. When the Tide has risen 12 Feet, at the Fort, the Falls are Smooth, after which during about 20 Minutes, they are passable. At times of great Freshets, which generally happen between the beginning of April, & the middle of May, from the melting of the Snow, the Falls are absolutely impassable, to Vessels bound up the River, as the Tide does not reach to their Level."
The counties are divided into parishes. Parishes are no longer used as geopolitical divisions, however, they are still used as expressions of a geographical area and by Statistics Canada as census subdivisions.
