AUSTRALIA-CORAL SEA.

OUTER ROUTE.

Reef's North-westward of Willis Group.

imation has been received from Commander W. U. Moore, H.M.S. Dart, of the existence of two coral reefs lying Bestward of Willis group, westward of the Outer route to Torres strait:-

Fe reefs (Moore Reefs) were passed in the forenoon of 1st January 1885; distant 2 miles, weather bright; they ash, and from the masthead appeared to be 3 to 4 miles apart, and to lie from each other in a N. by W. and S. by etion. The northern and smaller reef was estimated to be 2 miles long in a north and south direction, with a h of one mile.

The north-west extreme of Northern Moore reef is in lat. 15° 53′ S., long. 149° 9′ E.

-At 4 p.m. 21st January 1885, the Dart, from a position by observation, in lat. 15° 25′ S., long. 149° 4′ E., under steam S.S.W. W. a distance of 8 miles: thence a South course was steered, passing over the charted of the south-eastern of the two reefs seen by Bougainville in 1768. The weather at the time was not unfavourable ng breakers at the distance of 5 to 7 miles, but no indication of shoal water was discerned from the masthead. this tends to disprove the existence of a reef in the position assigned, it will for the present be retained on the alty Charts.

(The bearings and courses are Magnetic. Variation 63° Easterly in 1885.)
