Sandahan Harbour.-Great cantion should be used in approaching and entering this he bour, especially in vessels of over 12 feet draught. Good anchorage will be found well inside the entrance on the western ore, in from 9 to 6 fathoms, with a high peak bearing N.W. There are two small villages in the harbour, also a station of the Labuan Trading Company. Firewood and good water can be obtained from the natives, but no other supplies.
As it seems probable that many undiscovered dangers exist off that portion of the coast of Borneo south-eastward of the Banguey channel great care is necessary, and it is recommended that vessels should follow the lines of soundings shown on the Admiralty charts. The tides are irregular and the currents strong.
Caution. The natives of the Sulu islands are frequently engaged in hostilities with the Spanish, and Commander Buckle recommends that ships having occasion to communicate with them should previously hoist à flag of truce.

The information contained in this Notice is to be carefully considered, to be noted in the Sailing Directions, and compared with the chart when the Ship is navigating the parts to which it refers.

HONG KONG ISLAND.
With reference to that part of Hydrographic Notice No. 8, dated 15th March 1875, alluding to Bokhara rock :-Infor- mation has been received from Commodore J. Parish at Hong Kong, that the rock therein described is not the Bokhara rock which was originally found, and instead of there being only one, there are two distinct rocky heads, with nine fathoms between thein.*
Bokhara Rocks.-S.W. rock (on which the S.S. Bokhara struck) is a pinnacle rock with 3 fathoms on it at low water, from which Tathong rock bears N. by W. W., and cape D'Aguilar lighthouse W.S.W.
Buoy-A black and white chequered buoy has been moored in 9 fathoms close to the western edge of S.W. Bokhara rock, with Tathong rock bearing N. by W. W., and cape D'Aguilar W.S.W.
N.E. rock is a pinnacle rock with 18 feet water over it, situated about 1 cables N.N.E. E. from S.W. rock. From the centre of N.E. rock, Tathom rock is in line with the extreme of cape Collinson, bearing N. by W. 3 W.; the north-west point of Beaufort island is just shut in behind the rocky islet to the southward of cape D'Aguilar, S.W. souther- ly; and cape D'Aguilar lighthouse bears S.W. by W. W. distant 8 cables.
Directions.-Vessels bound to the southward through Tathong channel, and wishing to pass between Bokhara rocks and Hong Kong island, should, after passing to the eastward of Tathong rock, bring the summit of Beaufort island in line with cape D'Aguilar bearing S.S.W., and steer with that mark on, until Tatlong rock is in line with the left extreme of Taitoo island N. W., which mark should be kept on, until abreast of cape D'Aguilar. If passing to the westward of Tathong rock, the latter mark should be brought on as soon as convenient after passing that rock.
Vessels passing to the eastward of Bokhara rocks should not open Tatlong rock to the northward of Pottinger peak, until the southern extreme of Tytam peninsula is open south of cape D'Aguilar.
The most direct route for steam vessels leaving Hong Kong by Lyemun pass and through Tatlong channel is to pass west of Tathong and Bokhara rocks, and, after passing cape D'Aguilar steer so as to pass midway between Putoy and Sunkong islands, where there is a good channel with 15 to 20 fathoms mud.

JAPAN.
The following information, relating to sunken dangers on the coasts of Japan, hitherto unmarked on the charts, has been received from Captain H. C. St. John, R.N., H.M. Surveying vessel Sylvia, 1875.*
[All Bearings are Magnetic. Variation 4° 10′ Westerly in 1875.] INLAND SEA-AWA SIMA.
Awa rock is 23 cables long, in a W. by S. and E. by N. direction, a cable broad, and has from 7 to 12 feet water on it. From its eastern end the south-east point (the nearest part) of Awa Sima bears N.E. by N. distant 38 cables, Ko-yano- hana point and rocks, S.E. E. 14, miles.
Depths of 4 and 5 fathoms will be found near the rock.
KIUSIU, NORTH-WEST COAST.
Yobuko harbour-Rock_in_Ben-ten-no-Seto.-Near the extremity of the shoal which, in the immediate neighbourhood of Ben Ten islet, extends towards Kabe or Kata Sima, is a sunken rock, having less than 6 feet water. From the rock Ben Ten islet bears S.W. by W. W., a cable distant, the southern or nearest point of Kata Sima, N.W. W. 13 cables. There is a depth of 18 feet within half a cable north, east, and west, of the rock.
Kosime no Oosima (Wilson island) -Rock.-Off the north-east point of Kosime no Oosima, and half a mile distant from the shore, lies a sunken rock, with less than 6 feet water, which is steep-to around, having 6 and 7 fathoms close to.
The following bearings will give the position of this dangerous rock :—
The north-west extreme of Kosime no Oosima
The east extreme of Kosime no Oosima
