The position of the lighthouse on Low Head is as follows:  latitude 41 degrees 03 minutes 26 seconds South, longitude 4 degrees 25 minutes 44 seconds West, of Sydney; or 146 degrees 50 minutes 16 seconds East of Greenwich, variation 10 degrees 05 minutes easterly.  The light is elevated 140 feet above the sea-level, and may be seen, in clear weather, sixteen miles from the decks of small vessels, revolving once in fifty seconds.)

THE GLENNIE ISLES.

On December 19th both vessels left the Tamar; the Vansittart for Flinders Island, to land the unfortunate natives; whilst the Beagle crossed the strait to Wilson’s Promontory, anchoring behind an island two miles long, trending north and south, with a hollow in the centre, forming a saddle, the highest part being 450 feet high.  It is the northernmost of a group called the Glennie Islands, fronting the south-western face of the Promontory; and is strewn over with blocks of granite, which give it a castellated appearance.  We did not find this anchorage very good, the depth being 20 fathoms, and the bottom sand over rock.  Three small islets lie close to the south-west point, and a reef extends a cable’s length off the northern.  There is a passage nearly four miles wide, and 23 fathoms deep, between this part of Glennie’s Group and the Promontory.  The singular break in the high land on the latter, bearing East 1/2 North is a distant guide to the anchorage, in which the flood-tide sets to the northward, and when aided by the current, attains a strength of a knot and a half; the time of high-water, is a quarter of an hour later than at Refuge Cove.

We found on this, the largest of the group, a small black dog, that had been left behind by some visitor, recently I should say, from his anxiety to be taken on board, which was done.  It was, also, on this island that the intrepid Bass met a number of runaway convicts, who had been treacherously left by their companions one night when asleep, the party being too large for the boat they had run away with from Sydney, with the intention of plundering the wreck of the Sydney Cove, at Preservation Island in Banks Strait.  Thus they were actually the first to traverse this part of the Strait, which has received its name from the enterprising Mr. Bass.

CAPE LIPTRAP.

Leaving the Glennie Isles we examined the coast beyond Cape Liptrap;* and from thence made the best of our way to Western Port.  There I availed myself of the kind offer of Mr. Anderson—­a settler on the Bass River, who was going to Cape Patterson, to shoot wild cattle, the produce of the stock left behind when the old settlement was abandoned—­to give Mr. Fitzmaurice, and a small party, conveyance in his bullock dray to that projection, for the purpose of determining its position.  A party was also landed on the eastern entrance of Grant Island, to collect tidal observations.
