PlanPhilly: Planning Philadelphia's Future

Mr. Torben Jenk has recommended that we preface our map review with a demonstration by Jeff Locke of Colonial Instruments of seventeenth and eighteenth century survey tools since Jeff happens to be scheduled to be in Philadelphia that day. We have asked Jeff to speak for 1/2 hour and he will use a brief powerpoint I understand to open discussion on the compass, chain, drawing set and possibly theodolite he may bring. Jeff may also present a book made by a colonial survey student to practice his trade.

Lee Arnold of HSP says he would be honored to show these select maps and offer his insights. The gems which Torben suggested we may especially enjoy viewing include:
1) Original copper plate of Thomas Holme's Portraiture of the City of Philadelphia (1683)
2) Thomas Pierson and Isaac Taylor, 12 Mile Radius New Castle/ "The Figure of the Circular line Dividing Between the County of New Castle & County of (Chester)" (4 Dec 1701), their measurements (26 Nov 1701), and William Penn's instructions (28 Oct 1701) Am 2349 (folio)
3) British Army map of Philadelphia, 1777. Of610 (ca. 1777) b
4) Plan of the English Lines near Philadelphia 1777. Of 932* 1778 (from Am .602)
5) John Hill, Plan of Springettsbury Manor and other Estates. Cadwallader Collection, Maps, Flat File 4.
