The New York State library has also a manuscript _Map of part of the province of New York on Hudson’s River, the West End of Nassau Island, and part of New Jersey. Compiled pursuant to order of the Earl of Loudoun, Septbr. 17, 1757_. _Drawn by Captain [Samuel J.] Holland._ This is a map called by the Lords of Trade in 1766 “a very accurate and useful survey, ... in which the most material patents are marked and their boundaries described.” Something of the extension of settlements in the Mohawk Valley at this period can be learned from a manuscript _Map of the Country between Mohawk River and Wood Creek, with the Fortifications and buildings thereon in 1758_, likewise preserved in the State library.[518] A drawn map of New York province and adjacent parts (1759), from Maj. Christie’s surveys, is noted in the _King’s Maps_ (Brit. Mus.), ii. 527. The boundary controversy between New York and New Jersey has produced a long discussion over the successive developments of the historical geography of that part of the middle colonies. An important map on the subject is a long manuscript roll (5 × 2-6/12 feet), preserved in Harvard College library, which has been photographed by the regents of the University of the State of New York, and entitled _A copy of the general map, the most part compiled from actual survey by order of the commissioners appointed to settle the partition line between the provinces of New York and New Jersey_. 1769. _By Ber^d. Ratzer._ [New York, 1884.] 7-5/8 × 12-3/4 in.[519] Respecting the controversy over the New Hampshire grants, see the present volume (ante, p. 177), and Isaac Jennings’s _Memorials of a Century_ (Boston, 1869), chapters x. and xi. Of the special maps of Pennsylvania, the Holme map a little antedates the period of our survey.[520] The Gabriel Thomas map of Pennsylvania and New Jersey appeared near the end of the century (1698), and has already been reproduced.[521] In 1728 we find a map of the Delaware and Chesapeake bays in the _Atlas Maritimus et Commercialis_, published at London. In 1730 we note the map of Pennsylvania which appeared in Humphrey’s _Historical Account of the Society for the Propagation of the Gospel in Foreign Parts_.[522] [Illustration] About 1740, in a tract printed at London, _In Chancery. Breviate. John Penn, Thomas Penn, and Richard Penn, plaintiffs; Charles Calvert, defendant_,[523] appeared _A map of parts of the provinces of Pennsylvania and Maryland, with the counties of Newcastle, Kent, and Sussex in Delaware, according to the most exact surveys yet made, drawn in the year 1740_. The controversy over this boundary is followed in chapter iv. of the present volume. _A map of Philadelphia and parts adjacent, by N. Scull and G. Heap_, was published in 1750, of which there is a fac-simile (folding) in Scharf and Westcott’s _Philadelphia_, vol. i. The annexed fac-simile (p. 239) is from a plate in the _London Mag._, Dec., 1756.
