2) American ship "Mandarin"
From the New York Times, 16th Nov 1864 (the year is wrongly noted on the map, 1864, not 1869):
"The Rock on which the Ship Mandarin was Lost.
The following particulars of the unknown reef upon which the ship Mandarin was lost is from a letter received by ELLWOOD WALTER, Esq., Secretary of the Board of Underwriters, dated
BATAVIA, Monday, Sept. 26, 1864.
"The ship Mandarin, of New-York, owned by Messrs. WESTON & GRAY, No. 64th South-street, while under my command in the Java sea to the northward of the group of the Thousand Islands, on the 19th of August, at 7 P.M., struck on an unknown reef not laid down on any of our charts. Horsburgh 1845 and 1853, marked in the chart of 1845 as "a safe channel" with from sixteen to twenty fathoms of water. The bearings are as follows: North Island bearing N.N.W.; Small Island to the east of West Islands, due west; the North Watcher just in sight, due north. These bearings and positions are verified by the Capt. of the Government steamer Ambon, that came to our assistance. This reef is about 3 miles in extent running E.S.E. and W.N.W. We ran on and struck on a branch of rocks, with less than 12 feet of water. I refer you to the protest and reports of the Captain of the Ambon and Harbor-Master, for particulars. I would suggest that ships coming through Sunda Straits, not being provided with Dutch charts, should top, or send a boat on shore to the Harbor-Master's, where all the latest charts are to be had, the Government making it a depot for the same. By comparison, there are great and dangerous errors in our charts.
The reef on which we were wrecked is not on any but the latest Dutch charts (of 1863), and not correct on those, it being merely set down as a rock, whereas it is of great extent; and for the time we were on the wreck, it showed no break or ripple."
