342 REEF NEAR LOW ISLES. 



on board the Beagle, without a word of notice, 

 particularly as its features are in themselves suffi- 

 ciently remarkable, having a singular peaked sum- 

 mit 550 feet high, near the north-east end. On the 

 western side is a little cove where Captain King 

 found snug anchorage. Passing midway between 

 Green Island, which is about twenty feet high, 

 encircled with a coral reef, and Cape Grafton, we 

 steered N.W. ^ N. for a shoal on which Her 

 Majesty's Ship Imogene grounded ; and at noon, 

 were exactly on the spot, in lat. 16" 24^' S. by 

 observations and bearings of the land, Low Isles 

 being W.N.W. four miles. Here we found sixteen 

 fathoms, not having had less than seventeen since 

 the morning. There was no appearance of any 

 such reef nearer than that laid down by Lieu- 

 tenant Roe, bearing east from the above-mentioned 

 Low Isles and under which Her Majesty's Ship 

 Tamar anchored. It must therefore have been on the 

 N.W. part of this reef that the Imogene struck, and 

 the south part must be the reef laid down in 

 the chart as having been seen by her to the 

 southward, which accounts for our not seeing 

 it from the Beagle. We passed through several 

 patches of discoloured water, caused by washings 

 from reefs to windward, which are very deceptive. 

 At sunset the anchor was dropped in thirteen 

 fathoms, for the first time since leaving Port Ste- 

 phen. The south pjint of Weary Bay bore 

 W.N.W. three miles, and Cape Tribulation S. by E.
