Rough draughts of surveys, begun A.D. 1778
Entries through number 114 are in Erskine’s hand. Subsequent entries probably by DeWitt, although nos. 115 and 116 have been attributed to Washington by Guthorn. Frayed, split, abraded, stained and soiled, faded. Mounted on cloth, bound and cropped, disbound and silked by subsequent owners. Cleaned after removal of backings 1999; some fill remains. Sheathed in mylar. Imperfect: text lost to fraying and abrasion at three corners, upper and lower margins. Entries 126 through 129 lost to fading but are legible under longwave ultraviolet light. Index to 129 military topographic map titles which in turn describe a series of approximately 341 separate map sheets. (At least 283 of those sheets still exist; an additional dozen sheets appear to be related but are not indexed.) In its farthest conception, the index describes territory bounded by the Detroit River in the west, Lake Champlain in the north, the Connecticut River in the east and Charlestown, South Carolina in the south. However, most entries refer to western Connecticut, southeastern New York, northern New Jersey and eastern Pennsylvania. Pen-and-ink on laid paper. Pencil annotations are 19th or 20th century. Series title devised by cataloger is based on title proper. Watermark: "J WHATMAN". References: Guthorn, Peter J. American maps and map makers of the revolution, p. 17-22; Heusser, Albert H. George Washington’s map maker, p. 249-256.
