with great force.  Off the north end of Byam Martin’s Island are several smaller islets and coral reefs; the latter extend from it for more than six miles:  the north-westernmost of these islets is the land seen in 1801 by Captain Heywood, and was called by him Vulcan Point:  RED ISLAND, which he also saw, is eight miles to the westward; it is in latitude 15 degrees 13 minutes 15 seconds, and longitude 124 degrees 15 minutes 45 seconds:  between it and Champagny Isles the ebbing tide uncovered several extensive reefs.  Ten miles North 26 degrees East from Red Island, and South 71 degrees West from Freycinet’s Island, is a dry sandbank surrounded by a reef.

DEGERANDO ISLAND, so called by the French, is the southernmost of the CHAMPAGNY ISLES:  considerable reefs extend off its south end, which are dry at low water; its centre is in latitude 15 degrees 20 minutes 45 seconds, and longitude 124 degrees 13 minutes 15 seconds.

CAMDEN BAY is formed between Byam Martin’s Island and Pratt’s Islands, and extends to the eastward to Roger’s Strait; it is twelve miles deep and eight wide.  Here the tide rose and fell thirty-seven feet and a half, the moon’s age being nineteen days.  High water took place thirteen minutes after the moon’s transit.

Between Camden Bay and Point Swan, a distance of ninety miles, the mainland falls back, and forms a very considerable opening fronted by a multitude of islands, islets, and reefs, into which, from our loss of anchors; we were not able to penetrate.  From Camden Bay the islands, for the coast seemed too irregular to be the mainland, extend in a range in a south direction for more than fifty-five miles, to where there appeared to be a deep opening, or strait, from three to five miles wide.  An irregular line of coast then appeared to extend for seven leagues to the North-West, and afterwards to the westward for five or six leagues.  To the westward of this, the land appeared to be less continuous, and to be formed by a mass of islands separated by deep and narrow straits, through some of which the tide was observed to rush with considerable strength, foaming and curling in its stream, as if it were rushing through a bed of rocks:  this was particularly observed among the islands to the south of Macleay’s Islands.  After extending for thirty miles farther to the South-West, the land terminates evidently in islands, which then trend to the South-East; and to the westward they are separated from Cygnet Bay, and the land to the southward of it by a strait five or six leagues wide.  The narrowest part of this strait is at Point Cunningham, where it is twelve miles wide; two-thirds over to the islands are two rocky islets, which bear due south from Sunday Strait.
