As both of these Maps were originally official, one British and the other American ; as both were published from the respective manuscripts, as nearly aBpoBsible in /ac-simile; and as both are historical authorities of the highest character, they will be frequently referred to, in our narrative of the Military Operations in Westchester-county ; and, in order that our readers may also enjoy the benefits to be derived from a use of them, while reading the story of Westcbester-county's revolutionary history, the Publishers have re-produced them, at our request, as nearly in exact facsimile of the original publications, as possible. Sauthier's Map will be found opposite page 227 of this work, ante; and General Washington's Map will be found opposite this page of the same.

We may be permitted, however, to call the reader's attention to a singular error which was made in lettering the British Map. Where " Phil- "ipsbnrgh," [Philipsborough,'] or Yonkers, should have been designated the word "Wepperham"-- intended for "Neperhan," the nameof the stream, popularly known as the " Sawmill-river," at the mouth of which Philipsborough, or Yonkers, stood-has been erroneously inserted ; and, instead of designating Tarrytown, not "Terrytown," as situated miles adorns the Pocantico, on which the upper Manorhouse of the Manor of Philipsborough yet stands, that noted village ought to have been designated Wow that stream- indeed, the Pocantico ismade to appear as if it were the Neperhan, or Sawmill-river ; and Dobbs's-ferry and Tarrytown are consequently crowded up, into the immediate vicinity of the Crotonriver, although they are several miles below that stream ; and all the other lettering of the Map is similarly forced to the northward, unduly, in order that it may be made to correspond with the river-villages.
