Evans’ pamphlet is called Geographical, historical, political, philosophical, and mechanical essays. The first, containing an analysis of a general map of the middle British colonies in America; and of the country of the confederate Indians [etc.]. Philadelphia, 1755. iv. 32 pp. 4º. A second edition, with the title unchanged, appeared the same year, while “Part ii.” was published in the following year.[155]
By Gen. Shirley’s order N. Alexander made a map of the frontier posts from New York to Virginia, which is noted in the Catal. of the King’s maps (British Museum), ii. 24. This may be a duplicate of a MS. map said by Parkman (i. p. 422) to be in the Public Record office, America and West Indies, lxxxii., showing the position of thirty-five posts from the James River to Esopus on the Hudson.
Le Page du Pratz gave a “Carte de la Louisiane, par l’Auteur, 1757,” in his Histoire de la Louisiane (vol. i. p. 138), a part of which map is reproduced herewith. See also ante, p. 66.
In the Gentleman’s Magazine, 1757, p. 74, is “A map of that part of America which was the principal seat of war in 1756,” defining the Ottawa River as the bounds under the treaty of Utrecht.
Janvier’s L’Amérique, in 1760, carried the bounds of Louisiana to the Pacific.
Pouchot, in a letter dated at Montreal, April 14, 1758, describes a map, which he gives in his Mémoires, vol. iii., where it is called “Carte des frontières Françoises et Angloises dans le Canada depuis Montreal jusques au Fort Du Quesne.” It is reproduced in Dr. Hough’s translation of Pouchot, in the Pennsylvania Archives, second series, vi. p. 409, and in N. Y. Col. Hist., vol. x.
In 1760 Thomas Jefferys included a map of Canada and the north part of Louisiana in The Natural and Civil History of the French Dominion in North and South America, purporting to be “from the French of Mr. D’Anville, improved with the back settlements of Virginia and course of the Ohio, illustrated with geographical and historical remarks,” with marginal tables of “French Incroachments,” and “English titles to their settlements on the Continent.” This map ran the northern bounds of the English possessions along the St. Lawrence, up the Ottawa, across the lakes, and down the Illinois and the Mississippi. The northern bounds of Canada follow the height of land defining the southern limits of the Hudson Bay Company.
After the peace of 1763, Jefferys inserted copies of this map (dated 1762) in the Topography of North America and the West Indies (London, 1768), adding to it, “the boundaries of the Provinces since the Conquest laid down as settled by the King in Council.” The map of 1762 is reproduced in Mills’ Boundaries of Ontario.[156]
Jefferys also gave in the same book (1768) a map of the mouths of the Mississippi and the neighboring coasts, which, he says, was taken from several Spanish and French drafts, compared with D’Anville’s of 1752 and with P. Laval’s Voyage à Louisiane.
