What was advertised in a revolutionary American newspaper 250 years ago today?

“To the last Number for July, is affix’d a new and correct Plan of the TOWN of BOSTON, and PROVINCIAL CAMP.”

In the summer of 1775, Samuel Loudon, a bookseller in New York, stocked books printed by Robert Aitken in Philadelphia.  He advertised Military Instructions for Officers Detached in the Field, “DEDICATED TO His Excellency General Washington,” and The Art of Speaking in the August 21, 1775, edition of the New-York Gazette and Weekly Mercury.  He also noted that he stocked an assortment of paper and a “Variety of Books” that he “sold at the very lowest Price.”

Loudon concluded his advertisement by promoting another of Aitken’s projects.  The bookseller advised the public that he collected subscriptions “for that very useful and interesting “PENNSYLVANIA MAGAZINE, published by Mr. AITKEN.”  The Pennsylvania Magazine, or, American Monthly Museum commenced publication with its January 1775 issue, briefly overlapping with the Royal American Magazine.  Upon the demise of the latter, it became the only magazine published in the colonies.

To incite interest, Loudon noted that “the last Number for July” featured a “new and correct Plan of the TOWN of BOSTON, and PROVINCIAL CAMP.”  According to the Norman B. Leventhal Map and Education Center at the Boston Public Library, this map “was the earliest printed depiction of Boston after the battle of Bunker Hill, June 17, 1775.”  It includes an inset that “shows the location of the location of the battle, as well as provincial (American) lines in the communities surrounding Boston.”  This demonstrated “the commanding position enjoyed by the Continental Army.”

Getting a free map of Boston following the Battle of Bunker Hill was certainly an incentive to subscribe to the Pennsylvania Magazine!  But was it the first map of Boston created after that battle?  Perhaps, but it might better be described as one of the first depictions of Boston after the Battle of Bunker Hill.  A note in the Leventhal Center’s online catalog states, “This date is inferred,” likely because the map was “Engrav’d for the Pennsylva. Magazine” for July 1775.  Yet the assertion that it was the earliest printed depiction of Boston after the Battle of Bunker Hill may rely on an assumption that colonial printers published magazines at the beginning of the month when they instead issued monthly issues at the end of the month or early in the following month.  Thus, Aitken distributed the July 1775 issue of the Pennsylvania Magazine at the same time that he, Nicholas Brooks, and others advertised Bernard Romans’s map of Boston, a map that also featured an inset showing the “Provincial Lines” during the siege of the city and the site of the Battle of Bunker Hill.  Aitken may have consulted with Romans when preparing a map to accompany the magazine.  For prospective subscribers, it may not have mattered whether they acquired the first map of Boston published after the Battle of Bunker Hill, only that they had access to the map … and at a bargain price since it came as a premium with their subscription to the Pennsylvania Magazine rather than purchasing Romans’s map separately.
