[THE STILES SKETCH OF THE BROOKLYN WORKS.]

Now published for the first time, and quite important as confirming the Hessian map in vol. ii. of the Society's "Memoirs." The fortifications at Red Hook are undoubtedly exactly reproduced. Taken in connection with General Greene's orders, the sketch is valuable, enabling us to locate the works. The drawing, of course, is not precise, but the names and relative positions are enough as long as we have Ratzer to follow in the matter of outline and topography. The writer is indebted to the librarians of Yale College, Profs. Van Name and Dexter, for the favor of tracing the sketch from the original.

[EWING'S DRAUGHT.]

This is a one-half reduction from the original in the possession of Mr. Stauffler, of Lancaster, Pennsylvania, who has kindly furnished the writer with a tracing. It was drawn by John Ewing, Colonel Hand's brother-in-law, but in topography is far out the way. It contains, however, several important items in the references, which are noticed in the text.

[MAP OF NEW YORK CITY AND OF MANHATTAN ISLAND, WITH THE AMERICAN DEFENCES IN 1776.]

So far as known, no contemporary map exists showing the whole of Manhattan Island, except the very small and inaccurate sketches in Stedman, Sparks, and some other works. The one presented in this volume is believed to be the first to give the entire island, with its roads, settlements, and topographical features, as it lay in 1776. In the compilation, Ratzer and Montressor have been followed as far as they go—namely, from the Battery to about Fiftieth Street. From this point to King's Bridge the map of the commissioners who first laid out the island into streets in 1814 has been adopted. This is official, and gives the old roads as they existed during the Revolution. The Bloomingdale and King's Bridge roads are laid down in the present map as the commissioners have them, the surveys being made by Randall. The fortifications at Harlem Heights are from Sauthier's English map as given in New York Hist. MS. and Stedman.

[FIELD OF THE HARLEM HEIGHTS AFFAIR.]

Reference has been made to the topography of this battle-field in a note in [Chapter VI]. The outlines are taken from Randall's city map, and the ground has been frequently visited by the writer. Point of Rocks has been partly cut away, but the main features in the vicinity remain.

[NEW YORK AND BROOKLYN WITH THEIR ENVIRONS IN 1776.]

In this outline map, a bird's-eye view is presented of the entire position in this vicinity. Details will be found in the larger maps. Care has been taken to give the outlines, roads, and relative distances with accuracy. The plan is a photographic reduction of Ratzer's, Randall's, and Coast Survey charts.
