the centre of the port, a high rocky islet, the Lump, the 
summit of which is situated in latitude 15° 18' 30", and 
longitude 124° 37' 50". The western side of the port is an 
extensive island, Augustus Island, eleven miles long; it is 
high and rocky, and has several bays on its eastern side. 
The port affords very good anchorage, particularly between 
Entrance Island and the Lump, in nine fathoms, mud; but 
there is also very good anchorage with the Lump bearing 
west, in ten fathoms, mud. Port George the Fourth termi- 
nates in a strait, Roger's Strait, communicating with Cam- 
den Bay. The best entrance to the port is on the eastern 
side of Entrance Island ; for the opposite, although practi- 
cable and sufficiently deep for the largest ships, is narrow, 
and must be buoyed before it can be used. 
Point Adieu is the last land seen by us in 1820; 
it is the north-east end of Augustus Island, and is a rocky, 
bluff point. In the offing, at the distance of three miles, 
there is a considerable range of reefs, that extend from the 
peaked island of Jackson’s Isles; and more to the north- 
west is another group of rocky islands. 
To the westward of Augustus Island is a range of islands 
extending for five leagues ; on their north side they are 
fronted by considerable coral reefs, which at low water are 
dry ; besides which there are several small islets that con- 
tract the channels, and render the navigation intricate and 
difficult. Between Augustus and Byam Martin’s Islands 
there is an open strait, of one mile and a half wide; but, 
its communication with the sea to the north, appears to be 
little more than half a mile. Byam Martin’s Island is se- 
parated from a range of small islets, extending N.N.E. by a 
strait; and these last are divided from the Champagny Isles 
by another strait, from twenty-eight to thirty fathoms deep, 
through which the tide runs with great force. Oft* the north
