The St.
Lawrence River was a vital artery for the colonial powers, and for this reason, Bellin,
dAnville, Cook and others published attractive charts of it. This particular chart
was first published in 1757. In addition to the main chart, there are insets (small
charts) of good ports and basins along the river.
