Another important map is _The Provinces of New York and New Jersey with part of Pensilvania and the province of Quebec, drawn by Major Holland, Surveyor-General of the northern district in America, corrected and improved from the original materials by Govern^r, Pownall, Member of Parliament_. It was first published in London, June 15, 1775, and in a second edition, in 1776, there were added to it marginal maps of Amboy and the city and bay of New York. The _Brit. Mus. Map_, 1885, col. 2,969, shows the plates with different titles, dated 1775, 1776; also Frankfort, 1777, and London, 1777. Cf. the map in Mills's _Boundaries of Ontario_; the Evans map as reproduced by Jefferys, 1775 (see Vol. V. p. 85); the map in the _American Atlas_, and that of the country from the Chesapeake to the Connecticut, in the _Gent. Mag._, September, 1776.] The letters of Washington and Greene are still the main source of information for the evacuation of Fort Lee, which at once followed.[798] It may be well now to note some of the contemporary maps of the whole campaign, as indicating the extent and character of the geographical knowledge then current. The earliest of these is one which appeared in the supplement (p. 607) of the _Gentleman's Magazine_, 1776, and is called a _Map of the Progress of his Majesty's Armies_. Two of the American household manuals, _Low's Almanac_ (1776) and _Isaac Warren's Almanac_ (1777), had the same rude cut, a fac-simile of which, with the key, is shown below. [Illustration: LOW'S ALMANAC, 1777. KEY: A, Gen. Washington's lines on New York Island; B, fort at Powles Hook; C, Bunker Hill, near New York; D, the Sound; E, Kingsbridge; F, Hell Gate; G, Fort Constitution [Washington]; H, Mount Washington; I, Governor's Island.] A popular map (price one shilling) of _The Country twenty-five miles round New York, drawn by a gentleman from that City_, was also published in London, Jan. 1, 1777, by W. Hawkes, with a chronological table of events from Dec. 16, 1773, to Oct. 18, 1776. Des Barres issued in London, Jan. 17, 1777, a large map, _Plan of the operations of the army and fleet of Admiral and Lord Howe near New York, 1776_,[799] and a more popular presentation of the same field was made in the _Political Mag._, vol. ii. p. 657. The earliest attempt at historical rendering, Capt. Hall's _History of the Civil War in America_ (London, 1780), was accompanied by a map, a portion of which is here given in fac-simile; and Gordon (ii. 310), a few years later, gave an eclectic map, made in the main from American data.[800] [Illustration: NEW YORK AND VICINITY.
