IMPORTANT TO MARINERS.

No. 1. —A rock, situated to the eastward of the Island Tiri Tiri Mancangi, distant from the island about one mile and a quarter, having about one foot of water (spring), and 15 fathom water close to it on every side, from which the following bearings (magnetic) were taken—Southern extremity of the island S. W. & W., \ remarkable white rocky islet at the north-western extremity of the island, N. W. by W. -§• W., centre of the Little Barrier Island due north, peak of Rangitoto S. E. From the position and shape of the island, Tiri Tiri Mantangi not being correctly marked in the Admiralty Chart of the Gulf, the bearings of the distant land marks do not agree on the chart with those of the extremities of the island. No. 2.—A rock off the northern side of the Island of Waihekie, (marked on the charts position uncertain) from which the following bearings were taken : North-eastern end of Waihekie due east (magnetic) ; Bird Island, E. by N. } N. ; northern end of Hura Kia Island W. f S. ; peak of Rangitoto Island S. W. f W. This rock is even with the water’s edge at high water, and has deep water within a short distance on all sides of it. These bearings were taken by the only means in my power, at the time—a boat’s compass. No. 3.—A small roJty patch, about half a mile from

the shore, between the north head of the harbour and the first point of land outside, from which the following bearings were taken. * Extremity of the North Head S. 11 deg. West; Bastion Rock, S. 18deg. E. ; Beacon on the Southern Reef, S. 45 deg. E.; Signal Mast on Mount Victoria S. •18 deg. West. This rock has six feet of water on it at low water (springs), two fathoms (sandy bottom) about it, and four fathoms (mud) inside and outside of it. This small patch of volcanic rock had been accidently overlooked in the chart made by Captain Stanley, of H.M.S. Brittomart; a Red Buoy has recently been placed near it, : as it lies directly in the way of shipping entering the harbour, David Rough, Harbour master, Auckland.
