Nice example of the 1770 edition of Captain James Cook's map of part of the Gulf of St. Lawrence, which appeared in his second major cartographic work.
Prior to acheiving imortality on his 3 Voyages of exploration in the Pacific Ocean, Captain James Cook served the British Admiralty during the French & Indian War aboard the frigate Mercury. During this time, Cook undertook a hydrographic survey, which would lead to his first major cartographic production in 1759, his chart of the St Lawrence. Between 1759 and 1767, Cook continued his surveying work, conducting a systematic survey of the St. Lawrence and Newfoundland, along with his assistant Michael Lane who would finish the project after Cook's departure in 1767. The complete work would be published for the first time as a series of charts in 1770.
The chart provides a highly detailed treatment of the region, with soundings, islands, bays, shoals, and a host of other details noted in the map. The chart includes a number of inset charts of the harbors in the regon.
Cook would go on to captain the expedition to track the Transit of the Venus.
