The Chinese Government has given Notice, that on 12th July 1883, a light was exhibited from a lighthouse erected on the southern shoulder of Bonham island, the largest of the Bonham group, Parker islands :--

The light is a revolving light, showing alternate red and white flashes at intervals of half a minute; it is obscured by the high land of Bonham island between the bearings of Sa 4° 40′ W. and S. 47° 30′ W.; and to the northward and east- ward it is also obscured by Elliot, Raffles, and Senhouse islands, from S. 12° E. to S. 82° 15' W., with the exception of rays between S. 11° 25′ E. and S. 10° 35' E., between S. 2° 20′ E. and S. 0° 45′ E., between S. 1° 30′ W. and S. 3° 20′ W., and between S. 50° 5′ W. and S. 60° 10′ W.

The light is elevated 237 feet above the sea, and should be visible in clear weather from a distance of 22 miles. The illuminating apparatus is dioptric, or by lenses, of the third order.

The lighthouse 47 feet high, constructed of iron and circular in. shape, is painted red and white in horizontal bands; the dwellings are white.

Position approximate, lat. 30° 37′ 40′′ N., long. 122° 25′ 15′′ E.

Also, that the following fog signals have been established at Bonham island lighthouse :-

During thick or foggy weather-should a bell, fog horn, steam whistle, or other sound be heard, indicating the proxi- mity of a vessel, two guns will be fired with an interval of one minute between them; and if the vessel's fog signal is still heard, the firing will be repeated after an interval of eight minutes.

CAUTION.-Vessels should pass half a mile clear of the small islet lying 14 cables westward of Bonham island, in order to avoid outlying rocks which have from one to 2 fathoms on them at low water.

(The bearings are Magnetic. Variation 210 Westerly in 1883.)

EASTERN ARCHIPELAGO.

Sunda Strait-Navigation of; Also Lights.

•

With reference to Notice to Mariners, No. 254 (Preliminary), of 1st September 1883, on volcanic eruptions having taken place in Sunda strait, the charts of the locality being in consequence quite unreliable, and the lights destroyed :-

Further telegraphic information has been received from the Netherlands Government, through the Foreing Office, that the Great channel of Sunda strait is probably unchanged; but the channels between Krakatoa and Sebooko islands are blocked, and there is much floating pumice.

Also, that First point light, Java, is uninjured. A provisional light, visible about 12 miles, is shown from Flat cape (Vlakken hoek), Sumatra-the permanent light will probably be re-exhibited on or about the 17th September; Fourth point light, Java, is destroyed.

Precautionary measures are being taken by the Authorites, and Netherlands vessels of war will cruise for three months in entrances of Sunda strait to warn vessels.

Also, further telegraphic information, dated 12th September, has been received stating that the navigation of Sunda strait is now provisionally secured.
