CORRESPONDENCE. DAVIS'S SUN'S TRUE BEARING OR AZIMUTH TABLES. To the Editor of the "Nautical Magazine." SIB,-Allow me to draw your readers' attention to an erratum in my Azimuth Tables, kindly communicated to me by Captain James Gordon, of the s.s. City of Mecca. It is on page 194 under Declination 4°: NOTES OF A VOYAGE FROM CHINA TO AUSTRALIA. To the Editor of the "Nautical Magazine." SIR,-Having taken in your valuable journal for some years, and deriving a great deal of benefit from information found therein, I would like to contribute some items connected with a voyage from China to Australia, and back to China, which if you think worth you can publish. We left Hong Kong on the 11th August for Sydney, New South Wales, and passing out into the Pacific Ocean north of Luzon, proceeded south to the west of the Pellew islands, and passing within eight miles of the Sequiras Isles, as marked on Imray's sheet of the Eastern Archipelago, without seeing anything of them from the masthead at sunset, although the weather was clear. The next day, the 18th August, at noon, our latitude was 6° 56′ N., longitude 132° 36′ E. The day very clear, and favourable for seeing a long distance; but from the masthead we could see nothing of the Johannes Isles, which are laid down on the chart about this position. Our chronometers were rated in Hong Kong before we left, and the observations were good. We had light S.E. 1-3 winds from leaving Hong Kong till we got to 15° S., and from there to Sydney N.E. and Easterly, 3-4 fine weather; not a shower of rain. Currents from Luzon to 6° N., half a mile an hour to S.W.; 6° N. to 21° N., one mile an hour to Eastward; 24° N. to St. John's, one and a half mile an hour to Westward. Little current in the Coral Sea, and strong southerly currents on the coast of Australia. We passed between New Ireland and the Soloman group both going and coming, and had the currents nearly alike both times, and winds also till we got to 10° north, when we had N.E. winds. We passed in sight of Mellish reef, but saw beacon of any sort on it, so suppose it has been washed away. Squally Island, off the north coast of New Ireland, I found only to be about two miles square, instead of fifteen long and three broad, as it is in the charts I have; it is low, but covered with trees of a good height. Some canoes came off with about 40 men in them, and we saw about 150 more inhabitants on the shore. We passed within ten miles west of the island of Kumi (Meiaco-Sima Group), and saw no signs of broken water either to N.W. or S.W. of it, as reported and marked on charts; neither did we see anything of the Islet reported as existing in lat. 24° 9′ N., long. 122° 23′ E. We had clear weather and a moderately high sea. Found the Kuro-Sima current running 1 knot an hour as we passed Kumi. I am, dear Sir, yours very truly, S.S. Benledi, 9th November, 1879, JAMES ROSS, Master. RAPID STEAM COMMUNICATION WITH AUSTRALIA via CAPE OF GOOD HOPE.-The s.s. Orient, of which we spoke in the December number of the Nautical Magazine, has made the passage from Plymouth to Adelaide, calling at St. Vincent and the Cape in 37 days 22 hours; and, including the time of stoppage, in 36 steaming days.
