A bank with 18 feet at high water, runs out 14 cables E.S.E. of the south frontage of the dock, and this rises to a ridge of from 8 to 14 feet at high water. A post marks the shore end of the ridge which sometimes dries, and a red pear shaped buoy the outer end. The dock should therefore be approached from northward of East.
A ridge of 24 feet at high water, existed across the actual entrance, 20 yards outside the caisson, but this was being deepened to 27 feet.
A red mooring buoy is moored in 34 feet at low water springs, and a vessel 400 feet long, would just swing clear of the bank at half tide.

WEST COAST OF KOREA.
The following information relating to the entrance to Salee river, approach to Séoul, Prince Imperial Archipelago, and Prince Jerome gulf, is the result of a preliminary examination made by Lieutenant R. F. Hoskyn, H.M. surveying vessel Flying Fish, 1882.*

APPROACHES TO SALEE RIVER.
Shoals. A depth of 2 fathoms was obtained, S. by W. W., distant 104 miles from the south point of Sho-tung-tau, or Sho-Chung-tau island.
A depth of 1 fathoms was obtained, N.W. W., distant 63 miles from the summit of Moulaku-tau island. A bank of 1
fathoms lies E. by N., distant 4 miles from the summit of Moulaku-tau island, and apparently extends for a considerable distance in the direction of the island.
A bank of 1 to 2 fathoms, extends W. by S. about 3 miles from the south point of Whitthall group. Between this bank and the bank E. by N. of Moulaku-tau, there is a depth of 2 to 22 fathoms.
Between the south point of Whitthall group and the islet off the north-west point of Tcha-oul-to Marolles islands, there is a depth of from 16 to 20 fathoms. Shoal water extends from the Whitthall group to Richy island.
A bank, dry in places, extends 64 miles N.E. by E. 3 E. from the islet off the north-west point of Tcha-oul-to. The north-east extreme of this bank lies 23 miles S.W. by S. of the south point of Richy island. Between this bank and the shoal water lying between Whitthall group and Richy island, is a straight channel, 12 miles wide, with depths from 8 to 10 fathoms.
Directions.-Approaching Salee river by this route, caution is necessary in crossing the bar between Moulaku-tau and Whitthall group.
When about one mile south of the south point of Whitthall group, shape a course E. by N. & N., to pass half a mile south of Philip island, and when the western part of Richy island bears North, alter course to East, to pass southward of Round island, at the distance of a quarter to half a mile. From Round island to Rose island the existing chart will be found a sufficient guide.
Tides. It is high water, full
and change, at Rose island at 5h. 30m. (approx.), springs rise 29 ft. 8 in., neaps rise 24 ft. 3 in., neaps range 17 ft. 6 in. At Whitthall group, at 5h. 20m. (approx.), springs rise 24 ft. 3 in.
PRINCE IMPERIAL ARCHIPELAGO.
Sho-pai-oul. The island of Sho-pai-oul appears to be placed too far northward with regard to Fernande island and Sou-heng-tau. Caution is therefore necessary when entering Salee river by this route.
PRINCE JEROME GULF.
The Shoal, not completely examined, the south end of which lies 1 miles north of Seg-gumee, A-San anchorage, appears to extend for several miles in the direction of Eugenie island.
Directions.-Vessels may pass in safety on the north side of Eugenie island at a distance of one mile, and when the south point of that island bears West, distant about 2 miles, a course S.E. S. for the islet (50 feet high) situated on the reef of rocks north of Bagzug reef, will lead in deep water
