Prepared on the eve of the Seven Years\u2019 War (or French and Indian War), it was the second large format map of North America printed by the British (the first being Henry Popple\u2019s map of 1733), and included the most up to date information of the region: \u200b\u201cthe result of a uniquely successful solicitation of information from the colonies\u201d (Edney). Over the following two hundred years, it would play a significant role in the resolution of every significant dispute involving the northern border of the then British Colonies and in the definition of the borders of the new United States of America."}
