water" is not marked on Beatty's map. nor on the map of survey of the paten't in 1798, but it is marked, from existence or presumed existence, on a m.ip of the boundary line between New York and Massachusetts and seems to have been one of the several small streams that flow down the bluff from the surface, apparently abcmt two miles and a half north of Roelof Jansen's Kill, in the vicinity of the old Oak Hill station' on the H. R. R., later known as Catskill station. While referred to in connection with the boundmark to identify its location, its precise location seems to have been lost. In early days boundmarks were frequently designated in general terms by some well known place. Hence we find Catskill spoken of and particularly "the south end of Vastrix Island," a point that every voyager on the Hudson knew to be the commencement of a certain "rak" or sailing course.- Hence it was that Van Rensselaer's first purchase (1630) was bounded on the south by the south end of Beercn or Mahican Island, and the second purchase by the south end of Vastrix Island, which became the objective of the northwest bound of Livingston's Patent. While the name is repeatedly given as tha.t of the stream, it was probably that of a, place or point on the limestone bluff which here bounds the Hudson on the east

for- several miles. Surveyor Beatty's description, "Beginning at a place where," and the omission of the stream on his map, and its omission on subsequent maps of the manor, and the specific entry in the amended patent of 1715, "Beginning at a certain place called by the Indians Wahankassek," admit of no other conclusion, and the conclusion is, apparently, sustained by the name itself, which seems to be from Moh.
