[All Bearings are Magnetic. Variation 1° 30′ Easterly in 1871.]

Jeanie Brazlog.--The danger under this name has been found; it is a small sand islet on coral, the approximate position being in lat. 9° 2′ N., long, 119° 48′ 30′′ E.

Tub Betabo - A reof, 16 miles long, extending in a south-west and north-east direction, has been examined near the locality assigned to the Tub Batuba. On the reef are many sandy cays, and blocks of dark rock on a base of coral, and at the norchern extreme is a candy islet about 15 feet high, covered with scrub, and visible at a distance of 5 or 6 miles in clear weather; this isler lies in lat. 8° 54′ 48′′ N. and long. 120° 00′ 45′′ E.

As within the distance of 2 miles from this islet there is no bottom at 1000 fathoms, sounding would give no indication of the vicinity of the danger at night or in thick weather.

St. Micbad Ghoul is a large coral back, lying E.S.E. and W.S.W., 8 miles long by 2 broad, having regular soundings

of from 10 to 15 fathoms on it. The western extreme of the shoal is in lat. 7° 40′ N. and long, 118° 17′ 30′′ E., and from it the peak of Cuprum Sula can be seen in clear weather bearing S. by E. & E., distant 38 miles.

Vessels Day pass over or anchor on the shoal; the Nassau lay at anchor here four days in 10 fathoms, sand and coral, but There is no sufo ahorage about the St. Michael islands to the north-east of the shoal.

There are doop channels between the shoal and St. Michael islands, and be.reen the islands, but care must be taken to void the rocks that run off them, especially that off Manuk Manukan, which extends 34 miles to the north-west.

The Jam Beef was carefully sounded, and not less than 16 feet water found on it; the reef is about a mile in extent, and lies nearly midway between the islands of Bancuran and Bancawang in lat. 7° 50′ 10′′ N. and long. 118° 35′ E.

Bancuran has a dangerous reef extending from it to the westward for about 2 miles.

Strong side rip: were observed in the neighbourhood of the Java reef; these rips disturb the surface of the sea without any apparent card, and are generally in the deepest water.

Pudsey DarsonsAn extensive mass of coral patches was found in the neighbourhood of this shoal; on one of these patches as little as 19 feet was obtained, and is probably the shoal known as the Pudsey Dawson. The position of this shoal patch à lat. 7° 4′ N., Jong. 117° 46′ 30′′ E., and as the vicinity is known to abound with dangers, mariners are cautioned accordingly.
