The China Sea Directory, Vol. I., contains Sailing Directions
for the approaches to the China Sea by Malacca, Singapore, Sunda,
Banka, Caspar, Carimata, Rhio, Varella, and Durian Straits ; also
general observations on the passages from the Cape of Good Hope
to Sunda Strait aad Singapore.
The material used has been gathered from the following sources
Malacca strait from the surveys of Lieutenants Ward and
Jackson, Indian Navy, 1852-60. Portions of it, viz., the Lankawa
islands, Penang and its approaches, Diuding island and channel,
Perak river entrance and its approaches, and Larut river, have
been re-surveyed by Captain Napier, Commander the Honourable
F. Vereker, and Lieutenant H. Belam, in H.M. surveying vessels,
1876-84 ; also the south shore between Aroa islands and the
Carimon islands has been partially re-surveyed by the Dutch.
Singapore, Banka, and Rhio straits are from the surveys of
Messrs. Richards, Stanton, and Reed, Masters R,N., 1860-68, and
portions of Banka
Mr. Thompson, Government Surveyor, 1843-49 ;
and Rhio strait have been re-surveyed by the Dutch Government.
Durian strait is from the surveys of Lieutenants CoUinson and
Moresby, Indian Navy, 1822 ; Lieutenant Tjassens, Dutch Navy,
1843, with additions by Mr. Stanton, 1862.
Sunda strait to Banka strait is from various authorities. H.M.
surveying vessels in 1865-6 searched in vain for many reported
dangers and rectified the positions of others ; similar work is being
carried on by the Dutch surveyors ; yet, as no complete survey has
been made, vessels should navigate it with caution.
Gaspar and Caiirnata straits are principally from the re-surveys
made by the Dutch from 1880-5 ; the southern approaches to
Carimata were partially examined by H.M.'s surveying vessels
Sylvia and Nassau, 1874-6, and the Carimata islands, with some
of the Montaren group, were surveyed by Lieutenant H. Hoskyn,
H.M.S. Flying Fish in 1880. The positions of some of the out-
lying reefs, however, have yet to be investigated.
