Patuckquapaen and Tuscumcatick are noted in French's Gazetteer as names of record in what is now the town of Greenbush, Rensselaer County, without particular location. The first is in part Algonquian and in part Dutch. The original was, no doubt, _Patuckquapaug,_ as in Greenwich, Ct., meaning "Round pond." The Dutch changed _paug_ to _paen_ descriptive of the land--low land--so we have, as it stands, "Round land," "elevated hassocks of earth, roots," etc. (See Patuckquapaug.) The second name is written in several forms--Taescameatuck, Taescameesick, and Gessmesseecks. _Greenbush_ is an anglicism of _Gran Bosch,_ Dutch, meaning, literally, "Green forest." The river bank was fringed by a long stretch of spruce-pine woods. Dutch settlement began here about 1631. In 1641 a ferry was established at the mouth of the _Tamisquesuck_ or Beaver Creek, and has since been maintained. About the same year a small fort, known as Fort Cralo, was constructed by Van Rensselaer's superintendent. Poesten Kill, the name of a stream and of a town in Rensselaer County, is entered in deed to Van Rensselaer in 1630, "Petanac, the mill stream"; in other records, "_Petanac,_ the Molen Kil," and "De Laet's Marlen Kil and Waterval." _Petanac,_ the Indian name, is an equivalent of Stockbridge _Patternac,_ which King Ninham, in an affidavit, in 1762, declared meant "A fall of water, and nothing more." "Molen Kil" (Dutch), means "mill water." "De Laet's Marlen Kil ende Waterval," locates the name as that of a well-known waterfall on the stream of eighty feet. Weise, in his "History of Troy," wrote: "Having erected a saw-mill upon the kill for sawing posts and timber, which was known thereafter as Poesten mill, the name became extended to the stream," an explanation that seems to bear the marks of having been coined. From the character of the stream the name is probably a corruption of the Dutch _Boosen,_ "An angry stream," because of its rapid descent. The stream reaches the Hudson on the north line of Troy. (See Gesmessecks.) Paanpaach is quoted by Brodhead (Hist. N. Y.) as the name of the site of the city of Troy. It appears in 1659 in application to bottom lands known as "The Great Meadows," [FN-1] lying under the hills on the east side of the Hudson. At the date of settlement by Van der Huyden (1720), it is said there were stripes or patches within the limits of the present city which were known as "The corn-lands of the Indians," [FN-2] from which the interpretation in French's Gazetteer, "Fields of corn," which the name never meant in any language. The name may have had an Indian antecedent, but as it stands it is Dutch from _Paan-pacht,_ meaning "Low, soft land," or farm of leased land. The same name appears in _Paan-pack,_ Orange county, which see. * * * * * [FN-1] Weise's Hist. of Troy. [FN-2] Woodward's Reminiscences of Troy.
