ROCK OFF VAN DIEMEN'S LAND.
The Russian ship RURICK, in 1822, saw a dry rock above water off the south-east coast of Van Diemen's Land, in latitude 44 degrees, and longitude 147 degrees 45 minutes.
A rock was also seen by the ship LORD SIDMOUTH in 1819, in latitude 43 degrees 48 minutes, and longitude 147 degrees 15 minutes.

APPENDIX A.SECTION 8.
DIRECTIONS FOR THE PASSAGE WITHIN THE REEFS THROUGH TORRES STRAIT.
INNER ROUTE.
The passage recommended by Captain Flinders for passing through Torres Strait us by entering the reefs at Murray's Island; by which route a two-days' passage will carry a ship past all danger: but, as the space between Wreck Reef and Murray's Island is strewed with dangers, many of which have been discovered since the publication of his charts, and of which the greater number have only been recently seen, it cannot be called a safe navigation.

The dangers consist of low coral islands, surrounded by extensive reefs, upon which in long and dark nights a vessel is in momentary danger of striking; the result of which must be the certain destruction of the vessel, and the probable loss of the crew.
The Inner Route was first pursued by Mr.Cripps in the brig Cyclops, bound from Port Jackson to Bengal, in 1812.

It was subsequently followed by Lieutenant C.Jeffreys, R.N., in the command of the hired armed vessel Kangaroo, on her passage from Port Jackson to Ceylon, in 1815.* This officer drew a chart, with a track of his voyage up the coast; which, considering the shortness of his time, and other circumstances that prevented his obtaining the necessary data to lay down with accuracy so intricate and dangerous a passage, does him very great credit; he filled up the space between Endeavour River and Cape Direction, which Captain Cook did not see; the only part that had previously been left a blank upon the chart of New South Wales; his outline was found to be tolerably correct, and my alterations have only been caused by better opportunities, and by the greater detail of my operations.

The general feature of the coast has scarcely required correction; the principal corrections have been in the number, size, and relative bearings of the coral reefs and islands that front it.
