The treaty of Aix la Chapelle did not remove the previously existing controversies between the colonies of France and England respecting boundary. These controversies, originating in the manner in which their settlements had been made, and at first of small consequence, were now assuming a serious aspect. America was becoming an object of greater attention; and, as her importance increased, the question concerning limits became important also. {1749} In settling this continent, the powers of Europe, estimating the right of the natives at nothing, adopted, for their own government, the principle, that those who first discovered and took possession of any particular territory, became its rightful proprietors. But as only a small portion of it could then be reduced to actual occupation, the extent of country thus acquired was not well ascertained. Contests respecting prior discovery, and extent of possession, arose among all the first settlers. England terminated her controversy with Sweden and with Holland, by the early conquest of their territories; but her conflicting claims with France and with Spain, remained unadjusted. On the south, Spain had pretensions to the whole province of Georgia, while England had granted the country as far as the river St. Matheo, in Florida. On the north, the right of France to Canada was undisputed; but the country between the St. Lawrence and New England had been claimed by both nations, and granted by both. The first settlement appears to have been made by the French; but its principal town, called Port Royal, or Annapolis, had been repeatedly taken by the English; and, by the treaty of Utrecht, the whole province, by the name of Nova Scotia, or Acadie, according to its ancient limits had been ceded to them. But the boundaries of Nova Scotia, or Acadie, had never been ascertained. Though the treaty of Utrecht had provided that commissioners should be appointed by the two crowns, to adjust the limits of their respective colonies, the adjustment had never been made. France claimed to the Kennebec; and insisted "that only the peninsula which is formed by the bay of Fundy, the Atlantic ocean, and the gulf of St. Lawrence," was included in the cession of "Nova Scotia, or Acadie, according to its ancient limits." England, on the other hand, claimed all the country on the main land south of the river St. Lawrence. Under the treaty of Aix la Chapelle, commissioners were again appointed to settle these differences, who maintained the rights of their respective sovereigns with great ability, and laborious research; but their zeal produced a degree of asperity unfavourable to accommodation. While this contest for the cold and uninviting country of Nova Scotia was carried on with equal acrimony and talents, a controversy arose for richer and more extensive regions in the south and west.
