In erased pencil on recto: "No 77 C". Military topographic map. Covers the townships of Franklin and Readington in Hunterdon County, New Jersey. Shows roads running through Lansdowne, Hamden, Sunnyside, Stanton and Pleasant Run. Also shows buildings and owners’ names, landforms and streams. Notice that the verso title’s "Letter B of the same number" properly refers to sheet 77,B not to any mark on sheet 77,C. Pen-and-ink, pencil on laid paper. Shows relief by hachures. Title proper from recto is the work of a later editor--Simeon DeWitt or his assign--subsequent to 1820. Title from verso is in Erskine’s hand and may be cited as such. Index title, statement of responsibility, date, series title and series numbering also by Erskine, but on separate index sheet filed at head of series. Torn, stained, and badly abraded. Mounted on cloth, cropped and bound, disbound and silked by subsequent owners. Cleaned after removal of backings 1999; some fill remains. Sheathed in mylar. Watermark: "CC" under crown; the second C being reversed and interlocked with the first. No comparable mark is shown in Gravell and Miller.
