The document is one of the most elaborate of ancient land deeds. Besides confirming him in tin* ownership, it erects the estate into a manor called Philipseburgh or Philipseborough, and also confers upor> Philipse the privilege of building a bridge across Spuyten Duyvil Creek at Papirinemen, on the line of the then existing ferry, and authorizes him, in recompense for his expenses in that enterprise, to collect, for his own behoof, fares from all persons using the bridge. Although along the Hudson the lands of Philipse reached as far north as Croton Bay, their limits in the interior were considerably farther south, not being above the headwaters of the Bronx River; and thus the northern boundary of his property, as finally converted into the Manor of Philipseburgh, was a southeast line from the month of the Croton to the sources of the Bronx. At its northwest corner it touched the estate of Stephanas Van Cortlandt, the brother of his second wife -- an estate which also (1<;!>7| became one of the great manors, called Cortlandt Manor, running east from Croton Bay to the Connerticnt line, and including, besides almost the whole of the northern part of Westchester Comity, a tract on the west bank of the Hudson. Van Cortlandt's purchases did not begin until L683, about three years after Philipse had entered actively upon his land-absorbing operations. In addition to his various purchases in this county, Philipse bought of white people, in 1C>S7, the Tappan salt meadows lying opposite Ervington and Dobbs Ferry in the present County of Rockland, a comparatively small but finely situated tract, which was incorporated in the manor grant of June 12, 1693, and always remained a part of the hereditary manor. The ancestors of Frederick Philipse are said to have been Hussites of Bohemia, who, driven from their home by religious persecution, emigrated to Friesland, one of the provinces of the United Netherlands.
