The Beekman grant was on both sides of Rondout Creek west ^nd immediately above Honk Falls, where a large rock lying in the kill was the boundmark to which the name referred and from which it was extended to the stream and place. The George Davis grant has not been located, and may never have been taken up. Beekman sold to Peter Lowe in 1708, and the survey of the latter, in 1722, described his boundary as running west from "the great fall called Heneck." In Mr. Lindsay's History of Ulster County it is said that the grant was half a mile wide on the southeast side of the stream and a mile wide on the northwest side. Hon. Th. E. Benedict writes me : "The Rondout is eminently a river of rocks. It rises on the east side of Peekamoose, Table, and Lone mountains, and west side of Planover Mountain of the Catskills, and flows through chasms of giant rocks. All the way down there are notable rocks reared in midstream. The rock above Honk Falls is hogback shape, a hundred or more feet long. It lies entirely in the stream and divides it into two swift channels which join together just above the falls. Here, amid the roar, the swirl and dash of waters breaking through rocky barriers, with the rapids at the falls, the Great Rock was an object to be remembered as a boundmark." Without knowledge of the locative of the name or of the facts of record concerning it, the late Dr. D. G. Brinton, replying to inquiry, wrote me : "I take Magozv or M o ggew-assing-ink to be from Macheu (Del.), 'It is great, large'; achsun, 'stone', and ink locative ; literally 'at the place of the large stone'." The name does not describe the place where the rock lies.
