Brodhead suggested (Note K, Vol. i) that Pollepel Island was that known in early Dutch history as Prince's Island, or Murderer's Creek Island, and that thereon was erected Fort Wilhelmus, referred to by Wassenaer in 1626. (Doc. Hist. N. Y., iii, 35.) The evidence is quite clear, however, that the island to which Wassenaer referred was in the vicinity of Schodac, where there was also a Murderer's Creek. Hudson, on his exploration of the river which now bears his name, sailed into the bay immediately north of Butter Hill, now known as Newburgh Bay, on the morning of the 15th of September, 1709. After spending several days in the northern part of the river, he reached Newburgh Bay on his return voyage in the afternoon of September 29th, and cast anchor, or as stated in Juet's Journal, "Turned down to the edge of the mountains, or the northernmost of the mountains, and anchored, because the high lands hath many points, and a narrow channel, and hath many eddie winds. So we rode quietly all night." The hill or mountain long known as Breakneck, on the east side of the river, may be claimed as the northernmost, which would place his anchorage about midway between Newburgh and Pollepel Island. Quassaick, now so written, is of record, Qtiasck, 1709 ; "Near to a place called Qnasaik," 1709-10; Qviasseck, 1713; "Quassaick Creek upon Hudson's River," 1714. It was employed to locate the place of settlement of the Palatine immigrants in 1709 -- "The Parish of Quassaick," later, "The Parish of Newburgh." It is now preserved as the name of the creek which bounds (in part) the city of Newburgh on the south. "Near to a place called Quasek," indicates that the place of settlement was located by the name of some other place whioh was near to it and generally known by the name.
