The earliest American is the 1769 (or last) edition of what is known as Price's edition of Bonner's map of Boston, which had done service since 1722 by successive changes in the plate, this last issue showing Hancock's Wharf, and "Esqr. Hancock's seat" on Beacon Street.[603] This map sufficed for local use till the events of 1775 induced new interest in the topography, when the earliest response came from Philadelphia, where C. Lownes engraved _A new plan of Boston Harbour from an actual survey_, for the _Pennsylvania Magazine_. It presented a reminder of the great event of the year in its "N. B. Charlestown burnt, June 17, 1775, by the Regulars." There is another _Draught of the Harbour of Boston and the adjacent towns and roads_, a manuscript, dated 1775, among the _Belknap Papers_, i. 84, in the cabinet of the Mass. Hist. Society. The same _Pennsylvania Magazine_, the next month (July, 1775), gave as engraved by Aitkins _A new and correct plan of the town of Boston and Provincial Camp_. The town seems to be taken from a plan which had appeared in the _Gentleman's Magazine_ (London) the previous January; but in one corner was added a plan of the circumvallating lines of the besieging army.[604] Later in the season two other plans were made, showing the American lines, which were not published, however, till long after. One is given in Force's _American Archives_, 4th series, vol. iii.,[605] and the other was made by Col. John Trumbull, in Sept., 1775, which was published in his _Autobiography_ in 1841.[606] Of about the same time is another very small _Plan of Boston and its environs_, showing the circumvallating lines, which is in one corner of a large _Map of the Seat of Civil War in America_, engraved by B. Romans, and dedicated to Hancock. There is also, in the library of the Mass. Hist. Society, a rude plan of the harbor and vicinity, showing the positions of the provincials, which are reckoned at 20,000, while the royal forces are put at 8,000. I find no other American plan till Norman's, in 1781, reproduced on another page; and not another till _The Seat of the late War at Boston_ appeared in the _Universal Asylum and Columbian Magazine_, July, 1789, p. 444, but this is a rather scant map of the country as far inland as Worcester. Gordon had the year before this given a map in his _American Revolution_ (London, 1788) based on English sources; but it has been the foundation of most of the eclectic maps since published in this country.[607] In 1822 a Mr. Finch printed in _Silliman's Journal_ an account of the traces then remaining of the earthworks of the siege, both American and British.[608] There is an enumeration of the different sections of the lines, within and without Boston, in the _Mem. Hist. Boston_ (vol. iii. 104).[609] [Illustration: BOSTON AND VICINITY, JUNE, 1775.]
