HAINAN STRAITS.-The following banks have been examined off the Western entrance to the Straits. The bearings (Western Portion.) and distances are given from Cape Cami )Sand Hill) and shew the positions of the shoalest water BANKS.-found-from these positions the direction in which each bank lies is given, and also the distance thence
to the 5-fathom line :-
28ft. BANK.--N. 85° W., 6·8 miles, 28ft.-general depth also 28ft. It is a uarrow sand ridge lying
in a N. 43° W. direction 1.8 miles.
19ft. BANK.-N. 73° W., 12 miles, 19ft.-general depth 24ft.; extends N. 64° W., 0.3 miles and S. 61° W., 0.3 miles, which is also its greatest breadth. It is an oval sand bank- 8-fathoms mud will be got for 4 miles to N.W. of it.
24ft. BANK.-N. 88° W., 17 miles-least water and general depth 24ft.; extends N. 82° W., 0.6 miles and S. 79° W., 1.5 miles-greatest breadth 07 miles at the West end- Bottom sand-7 and 8-fathoms mud will be got for 4 miles to N.W. of it.
18ft. BANK.-S. 77 W., 29 miles, 18ft.-general depth 27ft., but 21ft. will be found in patches along its whole length-extends W. 1.5 miles and N. 68 E. 3-4 miles, thence E. 34 miles. It is a long narrow sand bank being about 1 mile wide near the position of the 18ft., and mile wide at its Eastern end.-Soundings of 7-fathoms stretch for 3 or 4 miles to N.W. of it.
SHOAL. A shoal having 3-fathoms over it at L.W.S. lies 9.3 miles E. S. of Cape Cami, and it is not safe to pass to the Northward of it.-Rocks extend under water from Cape Cami, 9 cables S. 20 W.
TIDES.It is H. W. F. and C. at Cape Cami at 2-45 P.M. when the sun is North of
the equator, and at 2-45 A.M. when the sun is South of the equator.
SHOAL EXPUNGED.-The 2-fathom shoal S.E. of Chai-une Island was searched for in vain by II. M. S. Magpie in 1881.
HAINAN ISLAND.-S.W. COAST.
COAST. The S. W. and W. coasts are incorrectly placed on Chart 2062, being from 5 to 10 miles West of their true position-From S.W. point the coast trends in an E.S.E. direction for 20 miles to Snake Point.- There are no islands West of Snake Point.
SHOALS. The bearings and distances are given from S.W. point:--A dangerous isolated breaking shoal lies N. 75° W., 18 miles. A 1-fathom shoal N. 861⁄2 W., 7-5 miles; a 4-fathom shoal lies S. 73 W., 45 miles, generally breaks, is 15 miles long in a N. 35 W. and a S. 35 E. direction; a shoal with about 2-fathom on it breaks N. 28 W., 18 miles; another with about the same depth breaks N. 34 W., 5 miles; a small shoal close in shore breaks N. 51 W., 0.5 miles; there is also shoal water S. 524 E., 13:5 miles.
Shoal Point bears N. 13 W., 22 miles from S.W. point, and breakers were seen 4 or 5 miles off it, shoal water apparently extending 5 or 6 miles to the Southward,
The bearings are magnetic :-
