[Robert Bolton, Jr. (1848)] the old town of the same name, and erected into a distinct town-ship;a both having been formerly included in the Manor of Phil-ipsburgh. It is situated six miles north-west of the village of "W'liite Plains, distant thirty three miles from New York and one hundred and nineteen from Albany; bounded north by Ossin-ing and Newcastlcj east by Northcastle, south by Greenburgh, and west by Ossin-ing and the Hudson river. This tract of land must originally have formed a portion of the ancient domains of VVeckquaskeck, as we find Weskora, sa-chem of tliat place, and Ghoharius, his brother, (a chief residing here,) conjointly selling lands, bordering the Pocanteco, to Fre-derick Philipse in the year 1680. Upon the district situated near the mouth of the Pocanteco river, (called by the English Mill river,) the Indians conferred the name of Pockerhoe. Pocanteco, the Indian name for the beautiful Mill river, is clearly a derivative from the Algonquin, Pockohantes,^ a term expressive of a '' run between two hills." The local term Pockerhoe also points to the saniie root for its ori-gin. Be this as it may, however, no signification could be more descriptive of this wizard stream, which pours its swift current through the foldings of a hundred hills. The Dutch styled it the Sleepy haven kili,c hence the origin of the present term Sleepy Hollow, as applied to the valley. • Mount Pleasant was originally organized on the 7th oi' March, 1788. Rev.
