Assinapink, the name of a small stream of water flowing to the Hudson from a lake bearing the same name--colloquially _Sinsapink_--known in Revolutionary history as Bloody Pond--is of record, "A small rivulet of water called _Assin-napa-ink_" (Cal. N, Y. Land Papers, 99), from _Assin,_ "stone"; _Napa,_ "lake, pond," or place of water, and _-ink,_ locative, literally, "Place of water at or on the stone." The current interpretation, "Water from the solid rock," is not specially inappropriate, as the lake is at the foot of the rocks of Bare Mountain. At a certain place in the course of the stream a legal description reads: "A whitewood tree standing near the southerly side of a ridge of rocks, lying on the south side of a brook there called by the Indians _Sickbosten_ Kill, and by the Christians Stony Brook." [FN] The Indians never called the stream _Sickbosten,_ unless they learned that word from the Dutch, for corrupted Dutch it is. The derivative is _Boos,_ "Wicked, evil, angry"; _Zich Boos Maken,_ "To grow angry," referring particularly to the character of the stream in freshets. * * * * * [FN] Adv. in Newburgh Mirror, June 18, 1798. Prince's Falls, so called in description of survey of patent to Samuel Staats, 1712: "Beginning at ye mouth of a small rivulet called by the Indians Assin-napa-ink, then up the river (Hudson) as it runs, two hundred chains, which is about four chains north of Prince's Falls, including a small rocky isle and a small piece of boggy meadow called John Cantton Huck; also a small slip of land on each side of a fall of water just below ye meadow at ye said John Cantonhuck." (Cal. N. Y. Land Papers, 99.) Long known as Buttermilk Falls and more recently as Highland Falls. In early days the falls were one of the most noted features on the lower Hudson. They were formed by the discharge over a precipice of the outlet waters of Bog-meadow Brook. They were called Prince's Falls in honor of Prince Maurice of Holland. The name was extended to the creek in the Staats survey--Prince's Kill. Manahawaghin is of record as the name of what is now known as Iona Island, in connection with "A certain tract of land on the west side of Hudson's River, beginning on the south side of a creek called Assinapink, together with a certain island and parcel of meadow called Manahawaghin, and by the Christians Salisbury Island." The island lies about one mile south of directly opposite Anthony's Nose, and is divided from the main land by a narrow channel or marshy water-course. The tract of land lies immediately north of the Donderberg; it was the site of the settlement known as Doodletown in Revolutionary history. The name is probably from _Mannahatin,_ the indefinite or diminutive form of _Mannahata,_ "The Island"--literally, "Small island." The last word of the record form is badly mangled. (See Manhattan.)
